Different Boiler Types

Nowadays, there are many boilers out there to choose from, so it can be helpful to get some guidance on which is the best option for your home. At WPJ Heating, we’re backed by our years of expertise in the plumbing and heating industry, providing boiler repair, maintenance and installation services to customers throughout South-West London, so we’re happy to shed some light on the main types of gas boilers on the market today, and to give our recommendations for the most discreet, energy-efficient options available.

Combination Boilers

Combination boilers are commonly seen in British homes thanks to their space-saving advantages and efficiency. As both heating and hot water are provided directly from combination boilers, there’s no need for a separate hot water cylinder; by delivering hot water through your pipes at mains pressure, there’s no need for a pump either. Combination boilers are also cheaper to install than conventional boilers, as they don’t require a tank in the roof space, so there’s less pipework for the installer to do.

Condensing Boilers

Known as condensing boilers because of the condensation they occasionally produce, these types of boilers are the ‘greenest’, most energy-efficient option. Condensing boilers can turn 90 per cent of the fuel they use into heat; by converting the water vapour from flue gases into liquid condensate, they use the latent heat of the exhaust gases to generate heating and hot water for your home.

Condensing boilers are so energy-efficient that governments in certain countries even offer incentives for installing them over other types of boilers. These are the only types of boilers we install at WPJ Heating, made by the world’s top manufacturers; we’re Worcester and Vaillant-accredited, so we can offer up to 12 year guarantee on our boilers.

Conventional Boilers

Conventional or regular boilers are older systems that directly heat your central heating system, and deliver hot water to a hot water cylinder. Conventional boilers take up a lot of space, as they need several different components to function: the boiler itself, a hot water cylinder, a cold water tank often found in the roof or loft, and a feed and expansion tank. As a result, installation time is longer and costlier, and repairs may be needed more frequently.

System Boilers

System boilers are neater, more efficient, and quicker to install than regular boilers, as many of the main components are built-in and there’s no need for a feed and expansion tank. System boilers take up the hot water expansion in the expansion vessel in the back of the boiler rather than the feed and expansion tank in the loft. They also house the pump, rather than having it as an external component.
