Hello, I have a Baxi DuoTec Combi 28 HE and 8 radiators.
I normally run it at 60-70 degrees flow temperature, but I wanted to see if I could run it at a lower temperature (can I get itnto condensate more? is my house heat pump ready?)
When I set it to 40 degrees the ‘gas’ light turns on while I hear the gas igniting inside, then the temperature rises rapidly reaching 50° in a matter of seconds, the fire and gas light turn off and the temperature drops to 30° in about a minute, then it ignites again and the temperature rises to 50° in a matter of seconds; then the cycle repeats.
Ok, the mean flow temperature may as well be 40° (oscillating between 30 and 50), but I don’t think this cycling is a good thing; does it even get a chance to condensate in those 5 seconds it stays on every 1-2 minutes?
The only way this doesn’t happen is if I set the flow temperature to 60°.
I have Tado valves and external sensors for each but 1 radiator and this test was done with all rooms calling for heat.
