The THERM series of condensing boilers marked “Only for heating” is primarily designated for heating buildings. These boilers are recommended in cases where heating of water is resolved in another manner, e.g., by an electric reservoir. Additionally, these boilers can be completed by heating water in an indirect heating reservoir with the use of an additional three-way valve accessory.
These types of sources are recommended for heating in systems in new buildings, low-energy houses and residential units. They achieve a maximum efficiency of 108 % when combined with floor heating. The outdated gas boiler in the existing heating system can also be replaced.
For residential units and industrial buildings with large heat losses, this series of boilers is supplied in the Thermona cascade boiler room version.
