	RE: GSHP WOES! Midland based engineer recommendations? By ASHP-BOBBA, 7 hours ago Forum Ground Source Heat Pump (GSHPs)
	@johnbroome perhaps, does it rise in pressure when heated and then drop when off?
	RE: Ecodan Pump Issues… Circulation pump turns off when heat pump compressor turns off By ASHP-BOBBA, 7 hours ago Forum Air Source Heat Pumps (ASHPs)
	can you see here it not like a set of steps every 20 mins, it runs flat for 2 or 3 hrs. I also currently have a Vaillant that is running 808hrs for 432 compressor starts, the best systems have 1 start...

	Please see attached graph from 8.5kW Ecodan serving a 244m2 hose new build 2025. see how the return flow is steady. This is dissipating it heat so it can run steady and holding the home temp at 23, th...

	@ashp-bobba Thanks so much for the info! Very helpful. I’ve realised we are having an issue where the pressure on the IVT keeps dropping - I’m wondering if our issue may be a failed expansion vessel.
	RE: Ecodan Pump Issues… Circulation pump turns off when heat pump compressor turns off By ASHP-BOBBA, 8 hours ago Forum Air Source Heat Pumps (ASHPs)
	Great this is open loop so surely the heating should remain on constantly? Or until it hits the target temp from the tcc? Looking at your graph you are not dissipating the heat so it is overshooting o...
	RE: Ecodan Pump Issues… Circulation pump turns off when heat pump compressor turns off By Patch321, 8 hours ago Forum Air Source Heat Pumps (ASHPs)
	@ashp-bobba interesting, but currently the way I’m running the ufh it’s constantly calling for heat, it will never satisfy the room thermostats. so surely the heating should remain on constantly? Or ...
	RE: Ecodan Pump Issues… Circulation pump turns off when heat pump compressor turns off By ASHP-BOBBA, 8 hours ago Forum Air Source Heat Pumps (ASHPs)
	So hear I am trying to explain there are several reasons the ASHP can pause, UFH says stop so it pauses, ASHP flow DT overshoot so the ASHP can no longer chase the curve it says pause. Whole house de...

	@patch321 ok, so if the ASHP heating "Play symbol" switches to "II" pause and the pumps stop that is fine it is just cycling and thinks the demand is off, if wired through the UFH system this will pla...

	@ashp-bobba Hi Bobba, It’s an FTC 6, house was built in 2024. Yes, when the play button goes it switches the pumps off. I’ve asked the plumber about the zoning, also about the pumps and the lo...

	RE: Getting ready for export By Batpred, 9 hours ago Forum Electricity, Tariffs, Monitoring & Providers
	So I hear the export MPAN that UKPN assigned should be put to use soon. 🙂 My learning in this process will be to argue more robustly (and immediately) when an electricians' firm (no matter ho...
	RE: Recommended home battery inverters + regulatory matters - help requested By Batpred, 9 hours ago Forum Energy Storage
	From what I read, the Solis has a very long list of error codes it reports in situations where the grid input does not conform to the defined standard. Clearly such tests are to be only done in a su...
