  1. How’s does your Ufh weather compensation affect your heat pump one?
  2. Not been a problem yet, have both heating and cooling on weather compensation so they shouldn’t hit the desired room temperatures on the stats. I suspect hot days and cold nights in autumn maybe a different story but I’ll see how it goes. I can change the deadband higher if needs be.
  3. Sounds complicated? I know you probably want to use what you’ve got but heatmiser fan coil stats are good https://heatmisershop.co.uk/app-control-fan-coil-thermostat/ It has 1 call for heat and 1 call for cool, used a relay to switch a volt free connection on my heat pump. Has a 2c deadband, my set up is heat to 20c and cool from 22c, flick automatically from each with both having weather compensation. If you get the neohub you can automate IFTTT app with octopus energy rates and local weather forecast, this service is all free.
  4. I’ve been running my fan coil units all summer on 12-14c flow temperature. I get water beading on my copper pipes when it’s really humid outside which isn’t too bad to worry about. The water coming out of the condensation trap I’ve had to bowls under them! A insulated pipes and condensate trap pipe work is on the list for me.
  5. I wonder how many on the list are actually doing cooling aswell? Done well tweaking your settings.
  6. I pay more in standing charge then i use in gas for cooking on the hob.
  7. @JohnMo off topic, what heat pump do you have? My friend is starting his self install heat pump and yours was a good price and quality.
  8. In 2008 you would need a buffer as they were all fixed output, now with inverter driven heats pump like yours they can modulate down to the heat demand. I managed to get a grant aerona3 10kw, megaflow cylinder and a cordvari buffer for £1600. Right place right time.
  9. When I was on octopus agile it was a lot cheaper then octopus intelligent go which currently on. Only swapping over because I got an electric van. On agile it’s cheapest between the 10am to 4pm. You can get tracking apps to tell your technology to come on when it’s cheapest 4 hour window. In summer you get paid to burn electricity. I would swap back but I need to charge my van (60kw) at night when I’m home.
  10. . I’ve got myson ivectors (1000x600) fan coil units, 1930’s detached outside walls insulated to 0.3 U-value. Running a flow temperature -2 35c on lowest fan speed nice and quiet. Now it’s 32c outside running it at 15c just above dew point and its fan speed 3 to keep 21c. So If you are thinking about cooling more than heat, insulated pipe work to run lower than dew point or bigger units if you can’t insulated pipework. These Panasonic units are a nice looking unit, some are nasty out there.
  11. I’ve got heatmiser fan coil stats do cooling and heat. Need 3 pole relay to get it to work because I’ve got a 4 pipe buffer setup.
  12. I got a tiny bit of condensation on my pipe works yesterday but it was very humid. 12c flow temperature seems to be the best outcome for me.
  13. I was having a look yesterday for my kitchen, found theses https://theheatpumps.co.uk/products/chilled-water-fan-coil-units.html I have no idea how quiet they are. Might be a starting point…. ive got myson Ivectors in the bedrooms quieter than a normal fan blowing about, managed to keep the bedrooms at 20-21 while it was 29c outside without insulating the pipework. They are control by heatmiser fan coil stat
  14. You could swap the radiators for fan coil units? I swapped mine beginning of last summer worked a treat. Not insulated the pipework, 16c is my flow temperature not had any issues. I’ve got myson Ivector units, think they are brilliant, lowered my heat flow temperature to 32c @ -2. My bedrooms suffer room overheating in the late evening, they kept the bedrooms at 20c on the hottest days last year.
