This system boiler has been designed and manufactured by Glow-worm, in the UK, to be a compact and lightweight unit so that it can be wall-mounted into your standard kitchen cupboard, out of sight, out of mind.
System boilers are ideal for homes with a high demand for instant hot water and central heating. This is because once the water that is supplied directly from the mains enters the boiler unit, it is then heated and stored in a separate hot water storage tank. However, this does mean that you will need to consider space for an additional tank when purchasing a new or replacement system boiler, and for this reason, we don’t recommend them for smaller homes with limited space.
Most of the important parts of the hot water and heating system, such as the pump and expansion vessel are pre-built into the unit, making it quicker and easier to install. This also means that you get a faster response to demand for heating and hot water, plus you don’t need to have a feed and expansion tank in the loft as you would need with a regular boiler.
