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 eciently 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 dierential 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 dierent 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 dierential
pressure and ow temperature
• XB06H+ Micro PlateTM heat exchanger:
- Low pressure loss
- Superior heat transfer
• High eciency pump capable of 7m head
• Reliable long-life AVTB regulation valve
