RE: Commencing on an ASHP Installation Process  

By Sheriff Fatman, 6 hours ago

Forum Air Source Heat Pumps (ASHPs)
  I prepared this analysis for a post on another forum (a football one!) for some people curious about heat pumps, and then subsequently realised that it would provide a good general update on the econo...

  Yes, more than an adjustment... This is the only combined inverter+ battery that I found (from Eleven) , but the specs look very high level:

Forum Energy Storage
  It is not AI, it was my own thinking! I was just describing a possible explanation. The fact that there is recent research about safety of lfp batteries (when, as far as I know, there have not been si...
RE: Poll for Time of Use, tariffs, technology

Forum Electricity, Tariffs, Monitoring & Providers
  @old_scientist Interesting point, but I suspect that's not a typical usage case for most people. I'm using Intelligent Octopus Go. I've looked previously at the Flux options and, on each occasion, ha...

  Not necessarily. Some more expensive batteries (e.g, GivEnergy, Tesla) also give access to more lucrative tariffs (Intelligent Octopus Flux), so one could base a strategy around the purchase of the ch...

  So, assuming any technical issues could be overcome, if you factored in a 16kWh battery cost at £2,000 or a 32kWh battery at £3,400 and added on a cost to install (they've been described as 'plug and ...

  We have solar, batteries and ASHP. We use seasonal tariffs. In the summer We use Intelligent Octopus Flux (we generate more than we consume, thus are net exporters) and in the winter we use Octopus Co...
RE: Different dT on each radiator?  

By JamesPa, 9 hours ago

Forum Thermostats, Volumisers, Buffer Tanks, TRVs, Pumps, Piping, Valves, Radiators & Controls
  I cant sorry. Its based on some calculations I did from Mitsubishi's R32 COP VS FT tables, which roughly gives a penalty of 3% for each degree increase in the DT at design OAT. Its a bit less, perha...
RE: Setback savings - fact or fiction?  

By JamesPa, 10 hours ago

Forum Air Source Heat Pumps (ASHPs)
  Maybe this: or maybe that the effect you are seeing is not caused by setback (correlation does not equal causality) or maybe it is but not due to the obvious thermodynamics - eg something to do with ...

  No, I haven't yet, and I will need to wait until I have enough post 'big bang' data to do it. I will look at how much data I already have tomorrow.
