3.3.2 Non return valves

To prevent heat losses through the connection lines when the
heat pump is turned off and during periods without drinking water
flowing (gravitational circulation), circulation brakes (set of two,
16 50 70) should be built into the connections to the ROTEX
High-efficiency hot water storage tank.

3.3.3 Dirt filter

If the ROTEX High-efficiency hot water storage tank is connected
to a heating system with steel pipes, radiators or non-diffusion-
proof floor heating pipes, slurry and swarf could enter the hot
water storage tank and cause blockages, local overheating or
corrosion. This can be prevented by fitting a dirt filter or sludge
trap (see ROTEX price list).

3.3.4 Scalding protection

There is a danger of scalding at hot water temperatures over
60 °C. Fitting scalding protection enables the hot water temper-
ature to be varied continuously and limited from 35 - 60 °C.
