	RE: DHW heat loss through pumps. By ngillam, 54 minutes ago Forum Domestic Hot Water & Cylinders
	@marzipan71 Morning, it looks as though it's a very much a "must have" in spaced out residences, do you witness the same temp drop from DHW tank on initial start up of pump as the pipework is primed? ...
	RE: British Gas vs Octopus Energy vs Heat Geek vs EDF vs Aira By Sheriff Fatman, 8 hours ago Forum Air Source Heat Pumps (ASHPs)
	A very interesting episode, and it was good to hear a constructive discussion from a group of contributors who are rivals within the same space. One thing that cropped up which I can absolutely attest...
	RE: Melpump Users Anywhere? By Sheriff Fatman, 10 hours ago Forum Air Source Heat Pumps (ASHPs)
	I signed up to Havenwise control on the day after the heat pump was commissioned so, unlike you, I don't have any prior data to compare to. I'm intrigued by how the algorithms are working on my syste...
	RE: Getting ready for export By Batpred, 10 hours ago Forum Electricity, Tariffs, Monitoring & Providers
	So I can now confirm that no MCS qualified person ever touched this! I used electricians and if anything, the installation was overspec´ed. I had it all inspected after labelling, etc, no changes were...
	RE: British Gas vs Octopus Energy vs Heat Geek vs EDF vs Aira By JamesPa, 10 hours ago Forum Air Source Heat Pumps (ASHPs)
	Really good episode thanks for that. Uplifting as well as informative and, dare I say, it giving real hope. The guy from heat geek (James?), 51 mins in, talks in very strong terms and with ref...
	RE: Octopus Cosy Heat Pump Owners & Discussion Thread By JamesPa, 11 hours ago Forum Air Source Heat Pumps (ASHPs)
	Very sound reasons imho. My current feel, albeit based almost entirely on hearsay and what they say, is that they have a good mass market offering. Two years ago they wouldn't do my property but if ...
	RE: Octopus Cosy Heat Pump Owners & Discussion Thread By AgentGeorge, 11 hours ago Forum Air Source Heat Pumps (ASHPs)
	@jamespa I chose Octopus as they will be in business far longer than any individual company, their heat pump uses R290, which is supposed to be state of the art better than R134, will see how the HP m...
	RE: Octopus Cosy Heat Pump Owners & Discussion Thread By swwils, 12 hours ago Forum Air Source Heat Pumps (ASHPs)
	@jamespa the insides are very well done. High quality compressor and inverter. Such a large monolithic case is also an achievement in itself. Personally I think the case geometry is going to be a ca...
	RE: Electricity price predictions By Batpred, 12 hours ago Forum Electricity, Tariffs, Monitoring & Providers
	In general, in order for the market to work and drive prices down, oversupply is required, so the more get closer to the finishing line, the better. As for evidence: When I talk about lack of sense...
	RE: Octopus Cosy Heat Pump Owners & Discussion Thread By JamesPa, 12 hours ago Forum Air Source Heat Pumps (ASHPs)
	That's interesting. We don't know what design trade offs octopus, or for that matter any other heat pump manufacturer, have made. Octopus however are particularly interesting, they are vertically in...
	RE: Electricity price predictions By JamesPa, 12 hours ago Forum Electricity, Tariffs, Monitoring & Providers
	That alone, assuming it's true, suggests that generation is too lucrative. Which prima facie is at variance with zero bids for a windrarm licence call about 2 years ago. What's changed, or are we ge...
	RE: Octopus Cosy Heat Pump Owners & Discussion Thread By AgentGeorge, 13 hours ago Forum Air Source Heat Pumps (ASHPs)
	Section 7 states the Cosy 6 is 5.63kW and can achieve COP of 4.29
