System gas boilers are ideal for homes that have a high demand for heating and hot water. System boilers are supplied with cold water directly from the mains, this water is then heated and stored in a hot water storage tank. This hot water is then sent to your radiators and your taps when needed.
It is important to note when purchasing a new or replacement system gas boiler, that you will need the space in your home for an additional 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.
The Glow-worm Energy System 15kW has a high-efficiency rating of 89.3% and an ErP A-rating for heating, meaning that this boiler could not only potentially help you to reduce your carbon footprint, but also lower your energy bills.
With an output of 15kW, this gas system boiler is better suited to smaller homes with less demand for heating and hot water. Nonetheless, this system boiler is still powerful enough to heat a home with up to 10 radiators and a single bathroom. If your home has a higher demand, the Energy System range also has outputs of 18kW, 25kW, and 30kW. The 12kW model is also available for those with lesser demand.
