Upgrading your boiler isn’t just about comfort. A new boiler can improve a building’s energy efficiency and reduce your home or business’s energy bills. But with so many boiler sizes, types, and features on the market, choosing the right one is not straightforward. That’s where expert guidance comes in.

Eco Happy takes the worry out of boiler installation in Brooklands. Our certified professionals will help you select the right boiler for your space and expertly install it. Proper installation avoids energy wastage, potential safety hazards, and unnecessary future repairs.

We’ve helped thousands of UK homeowners and businesses choose the optimal-sized boiler for their property that results in pleasing long-term savings!

What Type Of Boiler Do You Need?

You want a boiler that is the right fit for your property and heating needs. Firstly, it’s important to consider your fuel choices. You are probably connected to the gas grid. If not, LPG or oil are viable alternatives. You could also opt for cleaner electric heating.

Other key questions to consider include:

  • The property’s size and configuration.
  • How well insulated is the property? (a poorly insulated building needs a more powerful boiler).
  • How many rooms need heating? What temperatures do you prefer?
  • How many bathrooms and showers do you have?
  • How strong is your mains water pressure (a conventional or system boiler is usually better in low-pressure areas than a combi).
  • Are you looking for integration with your renewable power (like solar)?

It’s helpful to consult a heating expert who can identify the solutions that work best for your circumstances. Let’s explore the most popular options.

Combi boiler

Combi (or combination) boilers deliver heating and hot water from a single compact appliance. Unlike traditional boilers, there are no hot or cold water tanks. This is a tremendous space saver. Using gas, electricity, or oil, combis provide near-instant hot water, quiet performance, and top efficiency.

Sound too good to be true? There is one crucial downside. The standard combi struggles to supply hot water to multiple taps simultaneously. So, they don’t work well in households or properties with high hot water demand. They also aren’t as effective as traditional boilers in areas with low water pressure either.

Combi boilers are ideal for apartments, small homes, and offices with a single bathroom.

Electric boiler

Electric boilers offer a quiet, easy-to-install, and low-maintenance heating solution. They use heating elements (similar to a kettle) to heat the water distributed through the system.

Electric boilers are highly energy-efficient with the best models converting over 95% of electricity into heat. However, the running costs of electric boilers are high. Average electricity prices are 4 times higher than average gas prices in kWh (as of May 2024).

However, the running cost of an electric boiler falls significantly when electricity is generated from renewables. Connecting your boiler to solar or wind produces cheap, green, low-carbon heating. This makes electric boilers ideal for a green home or small office space. 

System boiler

System boilers effectively integrate a central heating system with a hot water cylinder. These boilers draw water directly from the mains supply to provide efficient heating and hot water without needing a cold water tank.

System boilers are great for active homes where several taps or showers often run at the same time. They also perform well in medium and large commercial buildings. A range of sizes ensures that systems can meet virtually every heating need. You can even get a system-combi hybrid which combines the combis’s compactness with the system’s hot water delivery capabilities.

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

Biomass boiler

A biomass boiler is a low-carbon heating setup that uses wood matter as its fuel source. Biomass boilers incorporate a water tank to provide central heating and hot water.

The more expensive models have an automatic fuel-feeding system while more affordable units must be manually fed. Either way, this technology isn’t cheap. Biomass boilers cost from £4,000 to over £10,000, excluding installation.

To assist property owners in installing a biomass boiler, the UK Government’s Boiler Upgrade Scheme (BUS) provides grants of £5,000. Biomass pellets, chips, and logs are also relatively affordable, costing on average 3p-7p per kWh. Running costs could work out on par with gas.

A biomass boiler is an effective option for larger homes, farms, and many business premises. These boilers aren’t ideal for properties with space limitations because the wood fuel is quite bulky and needs proper storage to prevent deterioration.

Conventional boiler

This traditional boiler and tank system heats the vast majority of UK properties. Modern conventional boilers – called condensing boilers – are energy efficient, boasting efficiencies of over 90%. Available in gas, LPG, or oil, there is a huge range of models and sizes to choose from.

Let’s talk about the conventional boiler ‘ban’. It’s true that gas boilers don’t feature in the government’s 2050 net zero plans and may be excluded from newly built properties after 2025. However conventional boilers are not banned and remain a vital source for home heating.

Conventional boilers can deliver heating to multiple rooms and hot water to several taps simultaneously. They are effective across all types and sizes of residential and commercial properties. 

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

The cost of installing a new boiler in Brooklands varies depending on the type of boiler and how difficult the installation is. 

Parts, labour, and a system flush factor into the costs of installation. If pipes need to be upgraded or connections re-configured, this certainly adds to the bill.  

When comparing boiler prices, you should also compare warranties. It’s probably worth paying an extra £300 if it buys you an extra 5 years of warranty coverage.

While every situation is different, here are the best cost estimates for new boilers in your area.

What Size Boiler Do You Need?

Boilers come in different sizes, ranging in power outputs from under 7 kW to over 70 kW. The more rooms and bathrooms you have, the larger the boiler you’ll need. 

A poorly insulated building similarly needs a more powerful setup because a higher percentage of heat escapes through leaky roofs, doors, walls, or windows.

Here are approximate boiler sizes for different residential and commercial property sizes.

For homes

A rough guide for homes says you need 1.5 kW- 2 kW of energy for every radiator in your home and 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. 

Note, that for combi boilers, you typically need a higher kW because its energy output is spread between providing heat and hot water simultaneously. 

Bedrooms BathroomsRadiatorsBoiler sizeType of boiler
111-69 kW – 18 kW (24 kW for combi)Combi, system, conventional, electric
211-1018 kW – 27 kW (30 kW for combi)Combi, conventional, electric, system
3-42-310-1630 kW – 35 kWSystem, conventional, biomass 
5+4+15 – 20+35 kW – 45 kWSystem, conventional, biomass

For commercial businesses

Commercial heating requirements vary widely from business to business. For example, the requirements of a small, boutique shop differ from a care home. Here is an idea of estimated boiler outputs for different-sized commercial properties.

When Should You Install A New Boiler?

When is the right time to replace an old boiler? Generally, once your boiler is in the 15-18-year range, it’s past its best. If costly boiler repairs become a trend (say every 6 months), you should invest in a new unit.

Rising heating bills without obvious explanation is another sign your boiler is underperforming. Other issues that indicate it may be time for a replacement include:

  • Disturbing noises from your boiler – rumbling, knocking, whistling, grinding and hissing.
  • Frequent leaks.
  • Erratic functioning and reoccurring fault codes.
  • Unexplained pressure fluctuations.
  • Your water or radiators take too long to heat up and don’t deliver the required heat.

Some of these issues may be due to worn parts or dirt buildup. Your boiler technician should be able to detect and resolve normal wear and tear. It’s worth reminding that regular servicing and maintenance are vital to your boiler’s longevity. A boiler service may cost £75 to £100 but it’s money well spent if it gives you a few more years of dependable service.

When is the best time of year to install a new boiler? 

The best time to install a new boiler is during the summer. It’s a quieter period for heating engineers so they can readily assist you. You also have more time to make this important investment decision and explore deals without feeling rushed.

Where will my boiler be installed?

A boiler should be installed inside the property, usually close to an external wall and somewhere easy to access. Boilers are most commonly installed in the kitchen, bathroom, or utility room. A gas boiler’s flue pipe must feed out of the building, through the exterior wall or the roof without posing a safety risk. An electric boiler doesn’t have a flue system, giving you more choice about its location.

How do I choose a boiler installer?

When choosing a boiler installer, research and check the reviews of the relevant installers. Be sure to ask questions about the proposed installation to understand all it involves. You want to get the installation agreement in writing and ensure the installer provides a warranty that ideally covers parts and labour.

What is Gas Safe certification?

The Gas Safe Register is the official gas registration body in the UK. It is a legal requirement in the country for gas boilers to be installed by Gas Safe registered professionals. Gas Safe engineers are trained and qualified to work safely and legally on gas appliances. This certification ensures high standards and compliance with safety regulations.
