108% Efficiency
Viwa ErP Boilers have the Gas Adaptive feature which ensures the ideal use of air-gas ratio for high efficiency operation.
Energy Class A
Viwa ErP Boilers are fully compliant with the ErP Directives of the European Union and save gas and electricity at the same time. ErP Viwa Boilers are energy class A.
Connection of up to 6 boilers and a total power of 390kW
Depending on the requirements of each installation, Viwa boilers can be connected in an array of up to 6 machines to produce a maximum central heating power of 390kW.
Easy View
With a multi-function digital display, ErP Viwa Boilers are easy to use and have an elegant design.
Long Lifespan
The stainless steel ErP Viwa Boiler exchanger ensures clean water for the system and extends the life of the boiler by reducing the risk of clogging to a minimum.
Just the Energy You Need
With a 1:7 modulation range, it adjusts its power according to your needs, offering savings and comfort.
Silent mode
Viwa ErP Boilers operate quietly thanks to the special 10 mm thick insulating material they have on their inner surface.
Absolute Security
ErP Viwa Boilers have a built-in particle separator and prevent air and particles from damaging the exchanger.
