Different Fuels to Power Your Boiler

Whilst most homes use the gas mains for boilers, there are other fuels available. Alternatives to gas include oil, coal, electricity, and biomass. Perhaps you live off-grid or you just want a different option to gas, here are some ideas. We are going to discuss six different fuels that can be used for your boiler, some you might have heard of, others not. This is the first step in choosing the right boiler type for your property.


1. Gas

First up is gas, which can be used to power your boiler if your home is connected to the mains gas line.


Gas is the most common fuel for heating your home. There are many benefits to gas, the main one being that it’s directly piped into your home via a supply company. Therefore, it’s extremely convenient as you will not run out of fuel for your heating.


However, gas is a fossil fuel. There’s no escaping the fact that natural gas releases greenhouse gases into the atmosphere. Home heating accounts for a large amount of UK emissions. Moreover, if you are not already on the gas mains supply, it can cost a lot of money to get set up.

2. Electric

Next, we have electricity. It is a good alternative to gas if you are not connected to the mains gas line.


Electric boilers use electricity as fuel. Therefore they don’t use up any fossil fuels, which means heat is not lost through flues or chimneys. Additionally, they are extremely efficient. If you use one, there is around a 99% efficiency rate. As well as this, it’s good to know they are almost silent, which means no more noisy boilers.


Nonetheless, electric boilers can be more expensive to run due to the cost of electricity over gas. Not only that, but some electric boilers are only able to heat up a small amount of the water you may need at any one time. Not to mention that if there is a power cut, your boiler won’t operate.

3. Oil

Another option to consider to fuel your boiler is oil. Mainly used if you live out in the countryside!


If you live in the countryside, you might not be on the main gas supply and perhaps you continue to rely on oil boilers. Oil is one of the best value alternatives to gas because the running costs are significantly lower. Furthermore, the efficiency of oil burners is extremely good because they only heat water on demand rather than storing it. Unlike gas, it doesn’t produce any harmful gases like carbon monoxide.


Even so, in most cases, you will probably need a tank installation outside the house. The tanks can be large and difficult to hide. Together with this, there are also several regulations on where to place it.

4. LPG

You might have heard of LPG, even though it is not very common. It is mainly used if you aren’t connected to the gas supply.


If your house is not connected to the mains gas supply, you can still use LPG which is an alternative to natural gas. LPG is a low carbon and therefore a clean-burning fuel that supports cleaner air quality.


Nevertheless, a disadvantage is that it’s less convenient. LPG arrives at your home in the form of 4-foot orange cylinders which need to be kept somewhere. As well as this, you will also need a boiler that is compatible with LPG. Hence, you’ll need a boiler conversion kit.

5. Coal and Coal-Based solid fuels

Now we are going to talk about a reliable energy source for your boiler, to keep your home running and warm this winter.


Coal energy is a reliable and affordable energy source. It’s easy to burn and produces high energy upon combustion. Moreover, it’s relatively inexpensive when you compare it to the other types of fuel. Solid fuel boilers can be aesthetically pleasing and provide cheaper energy bills.


However, solid fuel heating boilers using coal are mostly found in kitchen ranges. Furthermore, they can be inefficient as they consist of open fires. With this in mind, the fire providing the running heat must be active, even marginally, at all times.

6. Wood (Biomass)

A fuel that you might not have considered before this article, Which Type of Boiler is Best for my Property, is the fuel, wood.


A biomass boiler or wood boiler relies on wood pellets, chips, or logs to generate heat. If you have a biomass boiler, you are eligible for renewable heat incentives. Another benefit is that they emit around 3 tonnes less of carbon dioxide a year in comparison to a gas boiler. Wood pellet boilers are cheap in comparison to other alternatives.


Despite the benefits of biomass, not many homes are suitable for biomass boilers. As a matter of fact, they can be expensive to install and need a lot of space due to their size.

Our Top Boiler Fuel Recommendations

At Get Me A Boiler, we want you to have the best boiler for your home. The first thing to think about is the fuel for your boiler. If you choose a fuel that isn’t suited, then you could be spending more money on heating bills than first thought.

The Top 3 Boilers for 2021

Choosing a new boiler depends on many factors. From value to reliability, performance, warranty, and efficiency, there are a few things to consider. At Get Me A Boiler, we link you up with trusted gas safety engineers who can make recommendations for your home. Let’s have a look at the top 3 boilers for 2021. We discuss the top 3 boilers for gas, electric, and oil.

Top 3 Gas Boilers of 2021

Most homes in the UK are connected to the national grid, the main gas supply. The main advantage of a gas boiler is its convenience. Gas is pumped directly into your pipes through the mains supply and you can use it whenever you need to.

Top 3 Oil Boilers of 2021

Notably, if you live in the countryside and you are not connected to the mains gas supply, you may be continuing to rely on oil.

In general, oil is a good alternative to gas and tends to be the fuel of choice. It’s cheaper than electricity, gas, and LPG. However, with an oil boiler, you need a tank of oil that is kept somewhere on your property and is subject to a range of regulations.

Top 3 Electric Boilers of 2021

Electric boilers pass the water through an electric element to get it hot. In general, they are becoming more popular, especially if you are looking to reduce your carbon footprint. Or, if you are not connected to the gas mains supply and you are looking for a boiler.

They are relatively new to the market and there will be many more brands and models in the years to come. Here are the top 3 electric boilers of 2021.


The THERMAFlow Electric Combi Boiler

Generally speaking, using an electric boiler is more expensive than a gas boiler. However, the THERMAFlow Electric boiler is designed specifically to operate during periods of cheaper electricity tariffs. Hence, you can reduce running costs and energy while still meeting your hot water and heating needs.

This boiler stands upright on the floor and can be connected to a wood-burning or solar thermal system. Therefore, it helps to reduce your electricity usage, heating bills, and carbon footprint.

The Electromax by Heatrae Sadia

Thanks to its digital modulation, it can reduce energy consumption and therefore, your energy bills. The Mattira is available in 12 different outputs, so you can find the right model for your heating and hot water requirements.

Different Types of Boiler

There are different types of boiler that you must consider when selecting a new boiler to have installed. There are 3 main boiler types. The combi boiler, the conventional boiler, and the system boiler.

Combi Boiler

Fully known as the combination boiler, this is the most efficient type of boiler. Combi boilers are high in energy efficiency and this will help you to reduce your gas and electricity bills.

Because the combi boiler is only one unit, it’s compact and easy to fit into smaller spaces.

However, it can only provide a singular flow of hot water at any one time. Generally speaking, this means that you will be unable to run a hot bath and have hot water in the kitchen at the same time. It’s worth keeping this in mind when you are choosing a new boiler.

Conventional Boiler

A conventional boiler has an open vented heating system. This means it’s able to heat and store water to keep it warm until it is needed. Hence, conventional boilers can provide hot water for multiple taps and showers at the same time.

However, the conventional boiler needs both a hot water cylinder and a cold water tank. Hence it requires more space, such as an attic or loft.

System Boiler

The system boiler is also known as a sealed system. This means that it requires a hot water cylinder, but not a cold water tank. Therefore you don’t need the same amount of space as for a conventional boiler.

A system boiler has all the heating components built into it, hence the heating takes place inside the system. This makes it very economical to run. As well as this, it can provide hot water for more than one bath or shower at any one time.

Choosing the Type of Boiler


The amount of space you have in your home is a factor when you come to choosing which type of boiler.

For example, the combi boiler is ideally suitable for smaller homes for two reasons. The first is because of its compact size, which means it can fit into smaller spaces. Secondly, it can only provide hot water from the unit for one purpose. Hence, you can’t have hot water for multiple bathrooms at the same time.


The conventional boiler requires a great deal more space. This is because the whole system needs a hot water cylinder and a cold water tank. In general, more householders keep their tank in the loft or attic, so you will need this space to fit in the boiler.

A system boiler is a sealed system which means it does require more space than a combi boiler, but less than a conventional boiler. It can also provide hot water for multiple purposes.

Current Boiler

With this in view, your current boiler is also a factor in considering your next option. Replacing like for like is not necessarily the right way forward. Your heating requirements may have changed since the original boiler was fitted.

For example, perhaps your property now has double glazing or loft insulation which all help to reduced heat loss and therefore demand.

Or, your property may have an extension or additional bathrooms. This will increase the demand for heat and hot water.

Depending on what your current boiler is makes a difference to what you can choose now. Perhaps the infrastructure is not there in your home to choose a conventional boiler and it will be more expensive and difficult to install one. It’s worth talking to your gas heating engineer about what type will now suit your home.

Hot Water

Additionally, it matters how you use your hot water. Perhaps your family has grown since you last changed your boiler. Perhaps there are more needs for hot water in multiple bathrooms. You might need hot water from the kitchen tap, while someone else is in the shower. This is worth bearing in mind when choosing a new boiler.

Choosing the Size of a Boiler

Size of Property

Furthermore, the size of your property is a factor in considering choosing a new boiler. Previously in this article, we talked about the space you will need for each type of boiler.

An open vented system, such as a conventional boiler requires more space. Because it needs a cold water tank as well as a hot water cylinder. Usually, people put the cold tank in the loft or an attic. Therefore it is suitable for larger homes.

A sealed system, such as a systems boiler requires less space than a conventional boiler. It only needs a cylinder, not a tank. Hence, it’s also suitable for larger homes with more than one bathroom.

The combi boiler is the most compact type and can fit into a kitchen cupboard as it’s only a single unit. Therefore this is the most suitable option if your space is at a premium. A combi boiler is useful for smaller homes with one bathroom.

Water Demand

Another factor to consider is how much hot water you need. What are the demands you will make on your new boiler? For example, will there be more than one shower running at the same time? Do you want hot water for a bath and be able to use it for the washing up downstairs?

A combi boiler can only provide hot water for one purpose at a time. However, a conventional boiler heats up and stores the water for exactly when it is needed.

Heat Loss

Furthermore, it’s worth considering heat loss as a factor in choosing your new boiler. A bigger boiler isn’t necessarily the right option for a bigger home. As a homeowner, you might not complain about having more hot water and heat than you need. However, are you wasting energy as a result?

Consider the energy needs of your household. A heat loss calculation can help to determine the correct output for your boiler. Moreover, this will ensure that your boiler performs to expectation and doesn’t lead to heat and energy loss. If you are confused about which type of boiler to choose, it’s worth speaking to a professional gas engineer who can talk through the different options for your home.

Which Boiler is Best for My Home?

Choosing the right boiler for your home depends on many factors. These include the amount of heating you use, the size of your current boiler, its age, and fuel consumption. It also depends on the size of your property or room where you wish to store the boiler and cylinder or tank if needed.


1-2 bed flat

Firstly, if you have a smaller house, maybe a 1 or 2 bed flat, then you will need a compact boiler. The most popular type for smaller homes is a combi boiler. It can do two things at once, heat your home and heat your water, from a single small unit. Hence, it can even fit in a kitchen cupboard.

Combi boilers don’t need any extra elements. For example, a conventional boiler requires the boiler, a cylinder and a cold water tank. Therefore they are more suitable for homes with more space.

Moreover, if you only have one bathroom, then you won’t need such a powerful boiler. However, it’s just as important to find one that suits your requirements, you don’t want to see your energy bills begin to rise because it’s the wrong size of boiler for your home.

3 bed Flat

If you are living in a three-bed flat, it could be as part of a family or a flatshare scenario. This means that you may have more than one person using hot water at a time and may require a more powerful boiler.

Depending on the needs of your household, it’s still likely that a combi boiler is the best type for you in terms of space.

With this in view, it’s worth bearing in mind that electric combi boilers are available too and come close to 100% efficiency.

3 bed Semi

With a three-bedroom semi-detached house, you probably have more room. Therefore you may have more options to choose from.

If your home has two or more bathrooms, a System boiler may be suitable for you. It incorporates a hot water storage cylinder as well. This means it can supply lots of outlets with hot water at the same time without losing pressure. So two people can have a shower at the same time without dropping the temperature or power of it. However, the water won’t be ready to use instantly, as with a combi boiler. But when it’s heated up, you will have enough for everyone in the house to shower at once.

Like the combi boiler, a system boiler is a sealed system with one individual unit, making it easy to fit inside your home. However, it does come with the cylinder, so you will need a bit of extra room to store that.

If you’re confused about which is the right boiler to choose for your home, you can speak to an engineer who will be happy to help you find the right solution.

Four-bed house

There does reach a point when a combi boiler is not suitable for a type of property. And probably, it’s reached that point if you are living in a four-bedroom house.

Your choice of boiler will be affected by how many bathrooms you have. A system boiler or conventional boiler will be preferable here. Because both types of boiler can provide heating and hot water on demand to several outlets at a time.

A system boiler has the benefit of a separate hot water cylinder to hold a higher volume of hot water. Similarly, a conventional boiler has a separate hot water cylinder and a cold tank. Therefore it can also store large volumes of water and heat it up ready for use.

An average three or four-bedroom house typically has around ten radiators and will usually require a boiler with around 24-30kw. A larger house with substantially more radiators or an en-suite bathroom will generally need a bigger boiler, typically 30-35kw.

Low Pressure

If you are living in a low water pressure area, a combi boiler is probably not a good idea. Combi boilers are not as efficient in properties with poor flow rates or poor water pressure.

However, if you are stuck on the amount of space, then a combi boiler is still an option for you. It’s worth talking to a local gas engineer about the area you live in and what type of boiler is suitable.

Combi boilers require good incoming water pressure and good internal flow rates in order to operate. They need at least a 10 litres per minute flow rate to operate. If you have less than this, you’ll either needs a mains pump or a pressure accumulator tank.

An Old House

Perhaps you live in an old or listed house with old radiators or pipework. Generally speaking, a combi boiler is not a good idea here either. There could be a risk of leakages when installing a combi boiler.

A system boiler may be the better option here because they don’t need as much pipework as a conventional boiler, and you don’t need a big tank in the loft. However, if the house already has the pipework in it, you might find that it’s a lot cheaper to install a like for like replacement.

Furthermore, if your pipes are hard to access because the house is old or unusual, then you should consider sticking with the type of boiler you already have.

Eco-friendly options

If you want to keep warm and minimise your carbon footprint, the most important thing to consider is the energy efficiency of your home. A home that doesn’t waste energy is more eco-friendly.

You can improve your energy use easily, by turning down your thermostat, insulating your home, and having energy-efficient radiators. You could also use smart heating technology.

Boiler technology is regularly updated. Hence, there will be many more options in the future for eco-friendly boilers.

Whichever boiler you choose, make sure that you book an installation with a gas safe registered engineer.

Top 3 Heating Controls

Another thing to consider when choosing a new boiler for your home is the heating controls. Does your new boiler come with heating controls? Does it connect to your phone? Can you use your current heating controls?

Smart heating control

Smart heating controls allow you to manage your heating controls remotely from a computer, tablet or smartphone. Many have features that can control your heating in an even more sophisticated way. For example, some can learn from your previous choices and make adjustments for you. Others use automation and optimisation to help determine exactly when to turn the heating on.

A particular advantage of a smart heating control system is that you can also make changes remotely. Maybe you’re out somewhere for the day and you’re not going to return at your usual time. Then, you can just take out your phone and change the time your heating comes on if you are later than you thought.


Room Thermostat

A room thermostat prevents your home from getting warmer than necessary. They turn the heating on until your room reaches the desired temperature. For example, you have set the room thermostat to 21 degrees. If the temperature falls below this, the boiler will come on. If it reaches 21 degrees, then the heating goes off.

Room thermostats need a free flow of air so they must not be blocked by curtains or furniture or placed near heat sources. Your room’s thermostat should be set to the lowest comfortable temperature, typically between 18 and 21 degrees Celsius. If it’s cold outside, you don’t need to turn your thermostat up, the house will heat up anyway.

A programmable room thermostat combines time and temperature controls. Hence, it allows you to set different temperatures for different times of the day.

Radiator Heating Valve

Thermostatic radiator valves (TRV) allow you to adjust the temperature of individual radiators or turn them off completely.

The valves do not control the boiler. They reduce the flow of water through the radiator they are fitted to when the temperature goes above a certain setting.

You should set the to the level you want for the room. If you feel the radiator is not hot enough in a particular room, you can turn it up in that particular area.

How Heating Controls Can Help You

If you only want your boiler to come on at specific times, a heating control can help you. For example, maybe you only want your boiler to come on in the mornings and before you get home from work. Hence, you can set your timer and know that you won’t be wasting energy from your home.

Furthermore, a heating control can save you money, as well as energy. For example, you live in a typical three-bedroom semi-detached house that is heated by gas. If you install a room thermostat, you could save around £55 per year and 280kg in CO2 emissions, according to the energy saving trust.

By turning your room thermostat down by just 1 degree, you can save 10% on heating bills over a year. This equates to around £50 for the typical heating bill.

Another advantage is that you can heat up a particular room you are using instead of the whole house.

Steps to Getting a New Boiler

In this part of Which Type of Boiler is Best for my Property, we discuss the steps you need to take to get your new boiler installed. With Get Me a Boiler we make the process easier and less stressful.

Get a quote

If you’re looking at getting a new boiler, the first step is to get a quote for one. There are many different brands and types of boiler on the market. What you choose depends on several factors, including the age and size of your home, as well as the hot water and heating needs of your household.

For example, if you live in a 2 bed flat with 1 bathroom, you will probably need a combi boiler. This is small enough to fit into a kitchen cupboard and does two jobs, heating your home and providing hot water, in just one unit. Therefore it’s ideal for smaller homes.


Or, if you live in a 4 bedroom detached house with multiple bathrooms, you may wish to consider a system or conventional boiler. Both of these need extra elements so require more space to function. The advantage of a system or conventional boiler is that it can heat water for multiple outlets at the same time. So, more than one person can have a shower or bath at the same time and expect the same level and pressure of hot water.

But where do you go for a quote?

Firstly, you should always use a gas safe registered engineer. Again, quotes will vary on installing your boiler. A local, independent engineer may be cheaper than using an engineer from a big national company. However, it’s up to you to do your research on this.

Choose your boiler

When you have thought about the needs of your household, the next step is to choose which boiler you would like.

Different brands include Worcester Bosch, Vaillant, Ideal, and Baxi. These are only a sample. Perhaps you want the most eco-friendly boiler to suit your home. Or, maybe you are short on space and you just want the smallest, most efficient one.

Perhaps you live in an old home where complicated pipework means that you can only replace the boiler with a matching type.

If you’re confused about which type to get, it’s worth speaking to a gas engineer about it.

Get your new boiler installed

Next, make an appointment to get your new boiler installed. Again, depending on which type you go for, the engineer may need more time at your home. An easy installation, such as replacing like for like in a fairly new house should take a couple of hours.

But, if you are changing the type of boiler and need different infrastructure to support it, this could take many more hours.
