Alpha E-Tec 25R Regular Boiler

The Alpha E-Tec 25R 25kW is a wall-mountable, condensing regular boiler that is compact and lightweight, perfect for installation in your standard kitchen cupboard, out of sight, out of mind. However, 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.

The Alpha E-Tec 25R is the most powerful heat-only boiler that Alpha sells, with an output rating of 26.1kW for central heating. This model is perfect for medium-sized homes with a high demand for heating and hot water. This regular boiler could comfortably heat a home with up to 15 radiators with no issues.

However, if you feel that this may be too much power for your home, or you have less than 15 radiators, Alpha has designed the E-Tec 15R with an output of 15.1kW as well as the E-Tec 20R, with an output of 20.4kW, which could be better suited to your home.
