What Type Of Boiler Do You Need?

To find the right boiler for your unique circumstances consider the following questions: How big is your property? What are your heating and hot water needs? What type of boiler is being replaced? What are your environmental considerations? How insulated is your property? What is your budget?

The boiler fuel you opt for is also a critical consideration. Let’s touch on this briefly:

  • Gas and oil – dependable and relatively affordable but are being phased out in the long term.
  • Electricity – cleaner than gas, dependable but currently expensive.
  • Electricity from renewables – affordable and eco-friendly.
  • Biomass wood chips – affordable and relatively eco-friendly.
  • Hydrogen – we mention hydrogen because green hydrogen has been discussed as a substitute for gas; however hydrogen heating is not a realistic option at this stage.

There is plenty to think about when investing in a new boiler. Let’s explore the main boiler options and break down approximate costs and sizing guidelines.

Combi boiler

Best for:

  • Apartments
  • Smaller homes (with one or two bathrooms).
  • Smaller offices with low water demand.

A combi boiler is a compact appliance that heats your water on demand directly from the mains supply. These all-in-one boilers deliver quick hot water and efficient heating. They boast energy efficiencies of over 90% and sleek stylish designs.

Their main disadvantage is they struggle to supply hot water to more than one or two taps simultaneously. Additionally, they don’t work well in low-pressure water zones. There is a combi-hybrid incorporating a hot water tank that helps to overcome these challenges, but this invalidates the combi’s uniquely compact appeal.

Combis come in gas, electric, or oil variants.

system boiler

System boiler

Best for:

  • Most types of residential and commercial properties.
  • Work well in areas with low water pressure.

System boilers are similar to conventional boilers, except they connect directly to the water mains, eliminating the need for a cold water tank. A hot water storage tank is integrated into the system to ensure reliable warm water. Robust heat to radiators and underfloor heating is also delivered effectively. These boilers come in a wide range of sizes to suit different heating demands.

System boilers are a great choice for busy households where a shower, the washing machine, and the garden hose may all run at the same time.

Gas, electricity, oil, and LPG models are available.

Conventional boiler

Best for:

  • All types of residential and commercial properties.
  • Properties in areas where the water pressure is low.

The conventional boiler is the most tried and trusted of all the UK’s heating systems. These traditional (or heat-only) boilers have warmed millions of UK properties for generations. The system comprises a boiler unit, a hot water cylinder, and a cold water tank. This setup takes up more space than alternatives like combi boilers but provides dependable central heating to all types of properties.

Because they burn fossil fuels, conventional boilers are not part of our low-carbon future, so expect gas boiler installation to slow in the decades ahead. That said, these boilers are still an essential part of the UK’s heating mix and won’t be phased out for many years (though gas boiler installation in new builds may be discontinued from 2025).

Most heat-only boilers use natural gas. LPG and oil models are also available to cater to those off the gas grid.

conventional boiler
electric boiler

Electric boiler

Best for:

  • Small to medium-sized homes.
  • Small offices.
  • Modest-sized homes and offices powered by renewables.

Using electricity to heat water for your central heating system, electric boilers are highly efficient, with the best appliances exceeding 95% efficiency. They are also quiet and relatively easy to install.

Their main disadvantage is they are expensive to run. The average cost per kilowatt hour (kWh) of electricity is substantially higher than gas (24.50p compared to 6.04 per the latest Energy Price Cap adjustment). With an off-peak Economy 7/10 electricity plan, consumers can use the cheaper off-peak rates to reduce costs here somewhat.

The real win of electric boilers is when they are paired with renewable energy. If your property is powered by solar or wind, your boiler costs fall dramatically and your heating becomes truly clean and green.

Biomass boiler

Best for:

  • Larger homes.
  • Commercial premises.
  • Rural properties.

A biomass boiler uses wood pellets, logs, or chips as its fuel source. Biomass boilers are a low-carbon heating system – though they aren’t entirely eco-friendly. Trees are felled for fuel, but the industry does make active efforts to replace them and minimise the environmental impact.

Biomass pellets or logs are relatively cheap, costing on average 3p-7p per kWh (similar to gas). However, the capital outlay for biomass boilers is hefty. Automatic models cost over £10,000 while manual feeding models may cost you £5,000 (excluding installation).

Achieving 80-90% efficiency, these boilers are an effective heating solution for larger homes, farms, and a variety of business premises.

How Much Does It Cost To Install A New Boiler In Mirfield?

The cost of installing a new boiler in Mirfield varies depending on:

  • The type and model of boiler. With the range of products available, you can opt for a premium ‘all-bells-and-whistles’ unit or something more affordable. 
  • The complexity of the boiler installation. Replacing an old conventional boiler with a combi is quite involved, for example. It entails removing tanks and pipes, reconfiguring the system, and fitting new connections. The job tends to be more expensive than a simple combi-for-combi swap. 

Here are the cost estimates for new boilers in your area. Note that these are estimates because every situation is different.

The cost of complex installations in large premises gets pricey. Several powerful boilers may be required, taking weeks to install.

What Size Boiler Do You Need?

Boilers come in different sizes, ranging in power outputs from under 7 kW to over 70 kW (or even over 100 kW for some industries). More rooms and bathrooms (and radiators) = a larger boiler. A poorly insulated building similarly needs a more powerful boiler, since so much heat escapes through roofs, doors, walls, and windows.

A rough rule of thumb for households is 1.5 kW- 2 kW of energy for every radiator, plus around 3 kW for hot water. So a house with 10 larger radiators needs a boiler with a heat output of at least 23 kW.

Here are approximate boiler sizes for different size residential and commercial properties.

For homes

Note: For combi boilers you typically need a higher kW because the combi’s energy output is divided between providing heat and hot water simultaneously.

For commercial businesses

You’ll appreciate that commercial heating requirements differ widely from business to business. Here is an idea of estimated boiler outputs for different-sized commercial properties.

Can I install a boiler myself?

Installing a boiler is not a job for the amateur DIY enthusiast; it should be left to professionals. By law, a Gas Safe registered professional must install your gas boiler. For an electric boiler, you need an electrician or certified boiler technician. For oil boiler installations, an OFTEC (Oil Firing Technical Association) technician is recommended.

Why is boiler installation so expensive?

Boiler installations get expensive when the job is complex and takes two or three days. More standard installations can be done in less than a day, but even these cost several hundred pounds because you’re paying for the time of a certified technician plus all parts. Connecting the pipework and fittings, setting the thermostat and controls, and removing the old boiler all add to the bill.

Can a plumber install a boiler?

While boilers in the UK should be installed by qualified professionals – usually gas and heating engineers (Gas Safe registered for gas boilers) – some plumbers have the skills and are Gas Safe registered, allowing them to work on boilers. It’s important to check that your plumber is properly certified and competent to do the job before hiring them to install or service a boiler.
