The 2-in-1 increased coil boiler for Domestic Hot Water (DHW) & Buffer, combined with the Dotels Heat Pump, is the perfect combination for heating, cooling, and providing domestic hot water for your home.

The 2-in-1 boiler integrates the function of DHW production + buffer for heating (cooling), with excellent thermal insulation performance, a compact structure, simple installation and construction, saving a lot of space and installation costs.

The DHW tank uses indirect heating from a large internal coil surface to prevent the introduction of impurities into the DHW system.

For the inner part of the DHW tank, SUS304L stainless steel is used, thus obtaining much better corrosion resistance.

Advanced welding technologies have been used in the construction of the tank, which can effectively improve its quality and strength, and at the same time, can extend the life of the tank.
