Alpha E-Tec 20R Regular Boiler
Thanks to its high-efficiency rating of 92% and an ErP A rating for heat, the E-Tec 20R is an extremely efficient boiler that could also help you to save money on your energy bills.
With an output of 20.4kW, the Alpha E-Tec 20R is powerful enough for a small to medium-sized home with 10-15 radiators. However, if you feel that your home requires a higher demand for heating and hot water, the Alpha E-Tec range includes the 25R which has an output rating of 25kW. If your home does not require this amount of power, then the E-Tec 15R with an output of 15.1kW is also available.
It is important to note when purchasing a new or replacement regular gas boiler, that you will need to accommodate for an additional hot water storage cylinder and a cold water storage tank, which is usually installed in the attic. As a result of these additional elements, regular boilers are not recommended for homes with limited space.
