Vitoladens 300-C is an oil-fired condensing boiler with an excellent price/performance ratio
The Vitoladens 300-C oil condensing boiler is a premium product in its class. The tried-and-true energy system for detached and semi-detached houses is now equipped with the ability to run on a variety of Green Fuels Ready. These include HVO (hydrotreated vegetable oil), PTL (energy to liquid), and higher proportions of FAME (biodiesel) instead of fossil fuels. Therefore, this boiler is promising and can play an important role in climate protection.
Investing in the Vitoladens 300-C pays for itself quickly. Due to its high efficiency, it consumes much less fuel oil than older boilers. Due to its compact size, it takes up minimal space and can be configured to work with a sealed or open chimney. Therefore, it is well suited for a basement or utility room and is ideal for updating the heating system. In new construction, valuable space can be used for other purposes.
Green fuel is ready
