Heat Interface Unit /
KFS 722E ELECTRONICALLY CONTROLLED INDIRECT DOMESTIC HOT WATER & INDIRECT SPACE HEAT INTERFACE UNIT
Indirect Domestic Hot Water & Indirect Space Heating Heat Interface Unit
KODFLAT722E series Heat Interface Units are the most compact solution, operating with district heating system that require high static pressures and thermal medium temperatures.
The domestic hot water and space heating circuits are completely separate from the district heating circuit; no mixing and contamination are allowed.
KODFLAT722E is useful when designing or redesigning the heating and domestic hot water systems of apartment buildings under renovation, as well as facilitating any maintenance required in the individual dwellings.
