The Energy Regular is a gas boiler from Glow-worm, which has been designed with a variety of features and benefits in mind to create a highly reliable and long lasting boiler. The Regular will heat the central heating system directly, as well as provide hot water for a seperate cylinder, meaning a hot water storage cylinder will be needed, which is fed by a cold water storage cistern located in the loft. This may not be the choice for small homes but it is ideal for a like for like replacement of a regular boiler. This unit is a highly efficient A rated boiler with a rating of 89.3%. This boiler has an output of 25kW making it perfect for homes that do not have a high demand for hot water. This boiler is compact in size helping to save space in the home. The bright, modern LCD display provides clear and obvious status updates for both customer and installer. The Energy comes with the choice of a top or rear mounted flue giving it ultimate flexibility when you're choosing an installation site. Utilising an industry standard DIN layout makes boiler swaps quick and painless. The large waterways on the aluminium heat exchanger also makes it the perfect retrofit solution.
