Just thought I’d mention that the Guardian are asking for opinions on people’s heat pump experience. Of course I’ve provided mine.

I suspect this is the outcome of the survey. It’s a bit odd how Mitsubishi come out so well in each story. And that’s coming from me who has one. [image] At home with a heat pump: ‘It makes hot water when it’s freezing outside’ Four householders with recently installed air source heat …

Interesting article, I saw the call for contributions, I wonder if this is the first part of many or the final piece… How are you getting on with your heat pump @MyForest have you done any further optimisations? @muzza what do you have? have you been monitoring it’s performance? Here’s a screensh…

I have a 5kW Mitsubushi EcoDan with a 3m2 coil in a newark cylinder, I’ve got the FTC2b flow temperature controller for the EcoDan which lets me control the flow temperature using a voltage signal created using a digital to analog converter connected to a RaspberryPi…

a 5kW Mitsubushi EcoDan Your 5kW scales down way better than our 14kW one. It’s amazing to see yours being gentle and warming over a two hour stretch and hitting a CoP of over 4. Ours is like a tiger waiting to be unleashed and it races off to heat the water really quickly, so mostly it’s doing h…

Thanks for sharing @MyForest , yes I can imagine 14kW for DHW is going to push those temps up quickly! Do you have a large surface area coil or external heat exchanger? What is the deltaT between the max flow temperature and the DHW cylinder temp that you usually set it to reach? Here’s my flow tem…

[image] MyForest: My 16 year-old daughter said yesterday “when I move to my own house can I use your heat pump controller?” which is about the best review I can expect from someone who lives with the consequences of how it works. Great review! :slight_smile:

Thanks for the info. On a somewhat both related and not related topic and as currently a novice on the topic of Air Source Heat Pumps, what central heating control method(s) do they use? By this I am referring to the fact that traditional boiler heating systems originally used ‘call for heat’ contr…

[image] TrystanLea: @muzza what do you have? have you been monitoring it’s performance? Nothing that sophisticated (as documented by others here in this forum!) When I got my Solar installed 5 years ago my journey began. Installed a Pi and connected it to the inverter to monitor the Sun. Its …

Fantastic @muzza sounds like a good system! And a nice example of simple monitoring. I helped a friend install an EmonTx on an air-to-air heat pump a couple of weeks back, we put a CT sensor on the electricity supply and a temperature sensor either side of the indoor blower unit and that works real…
