Hot water
Hot water is produced in a copper coil. There are ribbed flanges on
the outside on the coil for best heat absorption. The cold incoming
water is mixed with the heated water from the coil in the mixing
valve (1). The mixing valve includes a thermostat where you set
the temperature on the outgoing water. If you don't run the boiler
with pellets there also is a possibility to heat the hot water with the
electrical heater which should be set to 70°C for good hot water
comfort. If the operating temperature of the burner or electrical
heater is too low, the coil will not deliver the quantity of hot water
as desired for larger amounts.
When hot water is prepared in a coil, legionella bacteria cannot
occur.

Valve combination
The combination valve is there so the hot water
temperature cannot scald. In order to increase the
temperature turn (1) towards +. You may also need to
tune the flow valve (6) to reduce the flow through the
coil. There is a safety valve (9) that releases the water
out of overflow tube (10) if the pressure in the hot water
circuit is too high. Note that overflow pipe should
always drain to a floor drain.
