	RE: Replacing my 18 month old ASHP By JamesPa, 55 minutes ago Forum Air Source Heat Pumps (ASHPs)
	Thats expected I wouldn't expect it to rattle. can you tell what is rattling?. I would expect it to be iced up Honestly no idea what cycle they run but the refrigerant has to be colder than the out...
	RE: Octopus Cosy Heat Pump Owners & Discussion Thread By AndrewJ, 1 hour ago Forum Air Source Heat Pumps (ASHPs)
	@agentgeorge Do you run on two zones then? I believe it is building regs that requires a TRV on every radiator except the one that is in the room with the thermostat. Bit crazy really as these days m...
	RE: 10kw heat pump run in 24*7 data? By JamesPa, 1 hour ago Forum Air Source Heat Pumps (ASHPs)
	Unless your house cools a lot during the setback, its still losing heat at almost the same rate - houses dont stop losing heat because you turn the heating off! All all that heat has to be replaced w...
	RE: Replacing my 18 month old ASHP By trebor12345, 1 hour ago Forum Air Source Heat Pumps (ASHPs)
	JamesPa Could I ask for your interpretation of the defrost algorithm for the heat pump? I am seeing a defrost at around an outside starting temperature of 5C. The evaporator gets to -18/20C prior to...

	RE: Getting ready for export By Majordennisbloodnok, 2 hours ago Forum Electricity, Tariffs, Monitoring & Providers
	No. There are already acceptable limits quoted and variations within that are to be expected. However, if I had historical data showing consistently high voltages during the summer months, I would fee...
	RE: Electricity price predictions By Jeff, 2 hours ago Forum Electricity, Tariffs, Monitoring & Providers
	Interesting logic. We could also drill for more gas in the North Sea during the transition to net zero. This wouldn't necessarily reduce costs unless it was cheaper than LNG but it would dramaticall...
	RE: Getting ready for export By Batpred, 2 hours ago Forum Electricity, Tariffs, Monitoring & Providers
	My inverter is set to use G99, so it would also automatically stop exporting, etc according the the normal rules expected. But 185 volts on your network is not acceptable, what has UKPN's response ...
	RE: Getting ready for export By Batpred, 2 hours ago Forum Electricity, Tariffs, Monitoring & Providers
	In my case, my voltage reads are now 240V. They should be 230V, so should I consume less? I see your point is to adjust on a personal level, but I am concerned that by letting UKPN believe that is an...

	RE: Getting ready for export By Jeff, 2 hours ago Forum Electricity, Tariffs, Monitoring & Providers
	Is the national 10% figure quoted somewhere @transparent? I assume you are looking at a different figure than me? The government gives a breakdown for total losses for 2024 at 9%, broken down as: Tra...
	RE: Getting ready for export By Majordennisbloodnok, 3 hours ago Forum Electricity, Tariffs, Monitoring & Providers
	I think you miss the point, @batpred. What I may or may not be doing isn't because of any emergency situation; all I'm doing is recognising that what I do as an individual has an effect at local level...
