Thanks to its efficiency rating of 89.3% and an ErP A-rating for central heating, this system boiler could potentially help you to lower your energy costs. This Glow-worm Energy system boiler has an output of 25kW, which is one of the more powerful boilers of its range, powerful enough to heat a home with up to 15 to 20 radiators and 1-2 bathrooms.
However, if your home requires a higher demand for heating and hot water, the Glow-worm Energy range has a more powerful output of 30kW available. Meanwhile, if your home doesn’t need this output of energy, the 12kW, 15kW or 18kW could be better suited to your home.
System boilers are ideal for homes that have a high demand for heating and hot water. System boilers heat cold water from the mains supply and store it in a hot water storage tank. This hot water is then ready on demand for when you need it.
It is important to note when purchasing a new or replacement system gas boiler, that you will need the space in your home for the hot water storage tank. If you have a smaller home with limited space, it may be better to consider the Glow-worm Energy combi boiler range.
