Vigas Boilers: 16-40 kW premium payment and RHI eligible

![]() |
Vigas 25 - 80 kW (Domestic and Commercial) Dunster Heat Limited is pleased to offer the full range of Vigas log fired central heating boilers. There are four models ranging from 25kW to 80kW in nominal output. In addition, there is a 25kW air heater model suitable for workshops. All the boilers employ the latest "gasification down burning" technology and have sophisticated electronic controls that ensure maximum efficiency and minimum emissions. All models comfortably exceed the best performance class of EN303-5, the British Standard governing solid fuel boilers. This is true both for efficiency and for emissions. Models 16-40 are eligible for grant aid underThe Microgeneration Certification Scheme (MCS). |
25Kw will heat and provide hot water for a 2 - 5 bedroomed house. 25Kw warm air will heat medium sized workshops.
