good quality strainer in the return flow to the unit will invalidate the
warranty on the unit.
6.7 TRVs
Where standard steel radiators are to be fitted, careful consideration
should be given before using Thermostatic Radiator Valves (TRVs) because
they are not designed to be used with low temperature systems. If the
decision
is taken to use TRVs, one should NOT be fitted in the same room
as a room thermostat.
6.8 Distribution Water Pump
If, as advised, you are using a buffer tank in the system, you will need to
fit a suitably sized water pump on the water distribution side of the
system. This water pump will need to be wired to receive an appropriate
signal from the heating system.
6.9 Glycol
The system
must be protected from freezing by using a glycol solution in
the water circuits. The glycol/water should be added into the system
from the expansion tank of the water loop or via the top of the buffer
tank. The following table details the volume of the glycol/water solution
mix:
% Glycol 10 20 30 40 50
Ambient Temp -3 -8 -14 -22 -33
Heating Capacity Fluctuation .991 .982 .972 .961 .946
Power Input Fluctuation .996 .992 .986 .976 .966
Water Flow Fluctuation 1.013 1.040 1.074 1.121 1.178
Water Drop Fluctuation 1.070 1.129 1.181 1.263 1.308
Note: if the glycol/water mix is too strong, the water flow and water
pump will be affected and the efficiency of the unit will be
decreased. The above table is for reference only and you should use
a glycol/water solution that is suited to local conditions.
