What Type Of Boiler Do You Need

A boiler is a big investment for your property, so making the right choice is important. Below are the various boiler types to consider for your home or business.

Combination (combi) Boiler

Combi boilers are single-unit boilers fueled by natural gas, electricity or oil. They heat water for taps and showers and provide central heating for your home. 

A combi boiler draws water from the main water supply and heats water on demand once a hot water outlet or central heating system is turned on. It does not need a hot water cylinder or storage tank, making it a very compact unit. 

These boilers have little to no standby heat loss. They are highly energy efficient and will ensure lower energy bills.

Combi boilers are best for smaller properties like apartments or townhouses with one or two bathrooms and low to medium hot water and central heating demands. Their compact size also suits homes with limited space.

system boiler

System boiler

System boilers use a heat exchanger, where water is heated by a burner fueled by gas or oil. 

The heated water is stored in a separate hot water cylinder, which takes up considerable space.

System boilers can heat a large amount of water, providing hot water and heat to multiple outlets. Additionally, their simple design makes them easy for heat engineers to fix when maintenance is needed. They are also quite energy efficient and can integrate with renewable energy sources like solar panels.

System boilers are best for large homes or small commercial properties as the hot water storage tank requires sufficient space.

Conventional boiler

Conventional boilers are the most widely used in the UK.

These boilers work almost identically to system boilers, except that they also have a tank where cold water is stored – typically in the loft. They also use a heat exchanger, where water is heated by a burner fueled by gas or oil. The heated water is then stored in a separate tank, ready for use.

They are very durable, so with proper maintenance, conventional boilers can provide reliable heating for well over a decade. However, It is important to note that conventional gas boilers are currently being phased out in the UK due to their carbon emissions. This means they aren’t going to be a good long-term investment. 

Conventional boilers are best used in large households or commercial properties with lots of bathrooms and high demands for heat. They produce a high heat output and can heat multiple water sources simultaneously.

electric boiler

Electric boiler

Electric boilers use electricity to heat water. They are an energy-efficient option and are also an excellent choice for properties where boilers fueled by gas or oil are not permitted, or the property isn’t connected to the gas grid.

Electric boilers are a great option for apartments, smaller homes, and small-scale commercial properties because they are small and don’t require additional space for a flue or chimney because they don’t use gas or oil as a fuel supply, and therefore, don’t require ventilation.

Biomass boiler

Biomass boilers are fueled by burning natural materials, the most common being wood, in the form of pellets, logs, or wood chips. These boilers are the most environmentally friendly option seeing that they don’t use fossil fuels. Biomass boilers are suitable for medium- or large-sized homes and businesses.

Something to note is that these boilers have a high upfront cost to install. However, the materials used to run a biomass boiler will be cheaper than those fueled by gas, oil, or LPG.

Large businesses

Large businesses will likely need much larger boilers. They have a significantly higher demand for hot water and heating, so they will require industrial boilers with 100 to 200 kW power outputs.

For this reason, boilers for large businesses are often exponentially more expensive than for small or medium-sized businesses. The table below shows the estimated costs of installing a new boiler for large businesses.

What Size Boiler Do You Need?

Like the types of boilers available, boiler sizes also vary. Usually, boilers range from 10kW to over 70kW. Your boiler size will depend on the property’s size and insulation. A larger property with a higher hot water and heating demand will need a much larger boiler than one with a lower demand.

Insulation is also important when deciding what size boiler you need. A well-insulated property means less heat loss, and you can get away with a smaller boiler for your central heating needs. The number of radiators on a property will also impact the size of the boiler you need, with more radiators needing a larger heating output.

Below are the estimated boiler sizes you will need for homes and commercial businesses.

For commercial businesses

The size of your boiler will depend on the size of your commercial business. Small and medium-sized businesses will require smaller boilers than large-scale businesses. This is due to hot water demand, the number of rooms on the property, and the number of radiators the property contains.

Below is a table with the estimated boiler sizes that your commercial property will need.

When Should You Install A New Boiler?

Whether you need a boiler service or opt for a complete boiler replacement will depend on several factors. Generally, you should replace your boiler if it is over 10- 12 years old or needs constant servicing, which will cost you more money to fix than buying a new one.

Below are some signs to look out for when you need to replace your boiler:

  • You need help finding parts to repair it, which could indicate it is too old
  • Constant leaking
  • Making abnormal sounds
  • Low water pressure
  • Rancid smells
  • Your water and energy bills are abnormally high (despite no change in usage behaviour)

The best time of year to install a new boiler is in summer.

Boiler companies and heating engineers will be less busy during summer. Winter months are chaotic regarding boiler emergencies, so it is not a great idea to try to schedule an installation then.
