Alpha has designed the E-Tec 20S system gas boiler to be a compact unit that can be fitted inside a standard kitchen cupboard, saving you space around your home.
However, it is important to note when purchasing a new or replacement system boiler, that an extra hot water cylinder is also required. Cold water enters the boiler from the mains water supply, gets heated, and is then stored in a hot water cylinder for when it's needed. Great for those who need hot water instantly.
The Alpha E-Tec 20S has an output of 26.1kW, which is perfect for small to medium-sized homes that have around 15 radiators and one bathroom. Meanwhile, if you feel that the 20S is not powerful enough for your home, Alpha has designed the 30S, with an output of 29.7W, for a home with higher demand.
