Popular Combi Boilers

Combi boilers do not require a hot water cylinder and header tank as they take their water supply directly from the mains and produce hot water on demand for both your radiators and taps.

Alpha’s InTec range of Combi boilers is suited to small to medium sized homes. The most popular range is the InTec C which is available in 2 outputs, but the more recent model – the InTec2 CE – is smaller and lighter and delivers better energy efficiency. They also offer the E-Tec range which includes a brand new stainless steel heat exchanger and is their smallest boiler yet.

The InTec S models are available in 3 different output for small, medium and large homes. They are compact in size and have been designed with simple installation in mind. The ProTec Plus range has been designed for installation in larger properties with a significant demand for heating and hot water. They are suitable for fan-assisted, sealed heating systems only.
