Description
Suitable for both New Build and Replacement applications on sealed systems, the new Vitodens 100-W System and Combi Boilers combine great performance with easy installation and maintenance.
The Vitodens 100-W also helps achieve long term savings on gas bills as it is designed to work with weather compensation controls.
As with all Vitodens Boilers, they feature the InoX-Radial stainless steel heat exchanger, designed and manufactured by Viessmann for high performance and long term reliability.
The modulating action of the MatriX pre-mix cylinder burner accurately matches output to the heat requirement for comfort and efficiency.
Both Combi and System models also benefit from Viessmann's space saving AquaBloc. All the hydraulic connections, along with the diverter valve, are centrally mounted and easily accessible for quick and easy routine maintenance.
General Testimonials
We replaced our old boiler recently with a Condensing Boiler and have noticed a big difference in both efficiency and cost. The boiler is reliable, easy to use, good quality and, perhaps most importantly, more efficient - we estimate about 20-30% cost savings compared with the previous one. We have an Evacuated Tube solar system and it works well with the new Condensing Boiler. The Installer Enerfina recommended to us was professional, competent and experienced and we are very happy overall with the service Enerfina provided.
