Condensing technology, the efficiency principle:
Condensing technology allows heat to be obtained in a very economical way. In a condensing appliance, a heat exchanger cools the water vapour sufficiently for it to turn back into water. Thus, the condensation heat contained in the waste gas is used to obtain additional heat.
The effect: More heat from less energy. Comfortcondens demos this, with a capacity factor of 106%.
Unique heat exchanger technology from bosch-WB5:
- Al-Si-alloy material with high resistance of corrosion
- Produced in sandcasting procedure, therefore getting a homogeneous microstructure
- High efficiency because of big area of heat-exchange
- Opening in front of the heatcell，easy service is possible
New generation control HIT3:
- Unique technology from Bosch, compaitable to Bosch Fx Controller
- Key lock (child protection)
- Extended service functions ( e.g. thermal disinfection ) and key pad navigation
- Weather depending controls for wall installation or integration in HT III
