Termix Solar A+

Wall-mounted domestic hot water module for ﬂats, single-family houses and apartment buildings

Application

The Termix Solar A+ is an instantaneous water heater, featuring superb heat extraction and high performance – due to the patented Micro PlateTM echnology and a high performance charging pump. Termix Solar A+ is applicable for heating systems with buffer accumulators, solar systems or for other heat sources, where a very low return temperature is preferred. The primary source is cooled out very eciently by the heat exchanger, thereby creating a very good operation economy. A ow switch in the domestic hot water pipe is controlling the primary pump. An optional circulation pump can maintain the circulating temperature at a desired temperature.

Domestic hot water (DHW)

The domestic hot water is prepared in the heat exchanger and the temperature is regulated with a thermostatic control valve. The AVTB valve ensures a stable hot water temperature by varying loads, ow temperatures and dierential pressure, without the need for readjusting the valve. There is no additional pressure loss on the secondary side of the heat exchanger with a thermostatic control. Therefore this unit is suitable in systems with low pressure in the cold water mains.

Options

The water heater can be provided with a circulation pump with safety valve, a white-laquered steel cover and two dierent ball valve sets (one set is with DVGW approval for DHW).

Construction

All pipes are made of stainless steel. The connections are made by nuts and gaskets. The brazed heat exchanger is made of copper and stainless steel with copper brazing.

FEATURES AND BENEFITS

• Domestic hot water module with tap capacity of up to 35l/min. at 90 kW

• Thermostatic control

• Operates independently of dierential pressure and ow temperature

• XB06H+ Micro PlateTM heat exchanger:

- Low pressure loss

- Superior heat transfer

• High eciency pump capable of 7m head

• Reliable long-life AVTB regulation valve
