Through their construction and the number of available options, THERM OKC and OKH storage tank water heaters provide economical preparation of hot water via energy from an external source. Heaters are fitted with temperature regulation of water, a safety valve and an outlet for circulation. For easy connection, THERM OKH storage tanks are all outlets in the upper part.
In the NTR storage tanks is one exchanger for converting energy from heating water to hot water. Two exchanges are used in storage tanks with large NTRR volumes. This enables to heat water from a source with a high output or to connect two various heat sources to each exchanger. With the THERM OKC 200 model series, any combination of gas boiler, alternative energy source or solar system is possible.
