cathodeRay RE: Testing new controls/monitoring for Midea Clone ASHP  

By cathodeRay, 2 weeks ago

  @benson - that looks encouraging. The all important IAT is stable apart from the solar gain boost, and no harm in that! It does (LWT flat lines), and I think the trigger is the OAT being somewhere in...
RE: Octopus Cosy Heat Pump Owners & Discussion Thread  

By JamesPa, 2 weeks ago

  This will differ from house to house depending on how it's set up. Because the octopus user manual is heavily dumbed down it's impossible to tell what the actual algorithm is. This is probably why y...

  I'm running 24/7 at 22c with no setback. Not tweaked any of the WC setting yet. I don't know how else to ask this and I sometimes think I must be speaking Martian as even on the Facebook Octopus group...

  I thought I would share some stats here too. As I said I run 24/7 at 21c and 19c setback overnight. I also do 2x 50c dhw cycles per day at 250L. With my solar PV and battery I have the following bill...
RE: Octopus Cosy Heat Pump Owners & Discussion Thread  

By AndrewJ, 2 weeks ago

  I'm assuming that it is cycling around the 21c and not running continuously? I'm on Intelligent Go with 16kW of battery and so far all my electric consumption since May has been at 7p although I've ...
RE: Replacing knackered oil boiler with Samsung ASHP - Perthshire  

By Mike H, 2 weeks ago

  The Water Outlet temp on the controller screen will display the current flow temperature whether in space heating mode or during DHW heating, so during the latter, you will see it rise above 50 degC. ...
RE: Testing new controls/monitoring for Midea Clone ASHP  

By benson, 2 weeks ago

  Hi again all, By way of quick update, today has probably been the first cold day of the year (at least down South anyway) so I've been keeping a close eye on how the ashp is performing. Here's the plo...
RE: Octopus Cosy Heat Pump Owners & Discussion Thread  

By wreckguru, 2 weeks ago

  @andrewj my house is pretty balance for supply and I have lazily adjusted just 2 TRV in 2 bedrooms from 5 to 3.5 and that's it.   I am running 21c all day everyday and 19c overnight.   I am ...

  @toodles Thanks - it would seem that apart from the cycling mine does (it can't ever stay continuous) then power consumption is similar.

  @andrewj In this chart, I have selected just the power demand and this in turn also indicates Attachment : IMG_1376.jpeg when the pump turns on and off. Regards, Toodles.

  @andrewj Here is a chart of ‘Today so far’, I have added the ‘Heating on/off’ data from which you can see that at the overnight temperatures, the pump stayed on ticking over; the system returned to cy...
Transparent RE: DHW Efficiency  

By Transparent, 2 weeks ago

  Do you need the DHW tank as high as 50°C @egp01 ? Have you tried running it at 45°C for a few days to see what effect it has on the COP?
