Alpha E-Tec Regular Heat Only Boiler 15–25kW
The Alpha E-Tec R is a compact natural gas regular (heat only) boiler with a stainless steel heat exchanger, an easy replacement for an old cast iron boiler on an open-vented system with a hot water cylinder. Choose the 15R, 20R or 25R. It can also run on a sealed system with the Alpha sealed system kit.

Required with this boiler: a flue kit
Alpha supplies this boiler without a flue. The Flue kit selector above Add to cart adds the Alpha CD EasyFlue 1000mm telescopic horizontal flue kit (6.2001010) by default, as a separate line in your basket. Pick the Alpha CD vertical flue terminal with 1m flue (6.2000520) instead for a roof exit.
Only choose "I already have this" if you already have a compatible Alpha CD 60/100 flue kit for this boiler. Check maximum flue lengths and terminal positions in the installation manual.

- Connection kit with gas service cock, wall mounting bracket, condensate discharge pipe and literature pack, as supplied by Alpha
