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. The Glow-worm Energy 18kW system boiler has an output that is powerful enough to heat a home with up to 15 radiators and a single bathroom.
If your home requires a higher demand for heating and hot water, the Glow-worm Energy range has the 25kW and 30kW also available. Meanwhile, if your home doesn’t need this output of energy, the 12kW or 15kW could be better suited to your home.
System gas boilers are ideal for homes that require a high demand for heating and hot water. This is because, with a system boiler, cold water is supplied directly from the mains and then heated and stored in a hot water storage tank. This hot water is then be sent to your radiators and your taps when needed.
However, 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.
