The circulation pumps in CTC’s products have energy efficiency class A.
11.3 Flow check
Once the system has been in operation and stabilised and as the outdoor
temperature gets colder, the temperature differential between HPout and
HPin should be checked so that the set flow speed is enough:
For heat pump in product range:
• EcoAir 400, see table in installation instructions for heat pump.
• EcoAir/EcoPart 600M series:
Underfloor heating: HPout–HPin should not exceed 5 degrees, when
rps > 20.
radiators: HPout–HPin should not exceed 10 degrees, when rps > 20.
If HPout–HPin is greater, the circulation pump speed should be
increased.
With an outdoor temperature of -15°C, the temperature differential
should be around 5/10 degrees depending on the temperature
differential the system is designed for.
• EcoPart 400, see table in installation instructions for heat pump.
