Caution with (older) diffusion-open plastic pipes,
e.g. existing underfloor heating
–
In the case of older underfloor heating, the dif-
fusion-open plastic pipes can result in increased
oxygen input in the heating system. This has a cor-
rosion-inducing effect on the heating system com-
ponents (see: Avoiding water-side corrosion
> 9 ).
– In this case, the system must be separated
(through installation of a heat exchanger).
– Newer plastic pipes (since around the mid 1980s)
are diffusion resistant in line with DIN 4726.
Buffer tank: Use, dimensioning
Advantages of using a buffer tank:
– The boiler can always be operated in the optimum
load range. This results in a longer boiler service
life and reduces emissions.
–
Avoids unnecessary boiler start phases, the hig-
her fuel consumption during the start phases is
significantly reduced.
– Continuously heated water is available in the buf-
fer tank for the heating circuit. The heating circuits
can therefore always be quickly supplied with
heat at all times.
If the heating system is operated without a buffer
tank, a hydraulic switch
> 10 must be installed.
Dimensioning the buffer tank:
For pellet boilers, a buffer tank volume of at 30 litres
per kW heating output is recommended.
Hydraulic switch
– A hydraulic switch separates the flows in the boi-
ler and heating circuits.
–
If the heating system is operated without a buffer
tank, a hydraulic switch must be installed bet-
ween flow and return.
Installing the dirt and sludge separator
– The separator removes circulating, magnetic and
non-magnetic free dirt and sludge particles (as of
5 μm) in fully-automatic continuous operation
from the heating system.
– Ensures the long-term, correct functioning of heat
generators, thermostatic valves, heat exchangers
and lowers the risk of defects and malfunctions
over the long-term.
–
Helps ensure quality heating water, even in the
case of existing systems, for example.
