Heat Pumps - post here.

Its unlikely that it will be just a switch or valve that you need to turn to fix it. It will most likely require a plumber so I'd be asking for plumber recommendations rather than advice on how to fix it considering that none of us will know how your system is plumbed/wired/etc.

At a guess maybe a faulty pump. Not something you'd be doing yourself.

Did you get someone out to fix the Solar? Maybe get them out again?

Hi folks, getting a Mitsubishi Split heat pump installed in two weeks. Comes with it's own controllers etc.

Just wondering what their controllers etc. are like, I've a hive system at the moment and just wondering if I sell it on?

Is there someone we can pay to come and assess the system and change from the defaults to tailor the system to our home? We had a guy service it last week, but he wasn't interested in tweaking or assessing the efficiency of the system.

Are these the flow temps?

Switched on heating mid month, from past years it will berate out during winter @ 12kwh per day for hot water and under floor. Heating is exclusively night rate @14c. Hot water is about 2kwh of the above and can come on at any time

panels and battery due to go in next month

Just did. https://www.boards.ie/discussion/2058320305/heat-pump-quotes/p1?new=1

How do you check/adjust the flow temps on Joule/Samsung gen 6 system as per my pic above? The manual isn't very clear.

Yes, ufh everywhere no rads. on default settings after commissioning my flow temps were actually in the 40's, madness!

I tried the weather compensation for a while but I didnt like it. So now i set the flow temp manually at 26-28c depending on the outside temp.

Fair play, a lot of others would just leave the settings at default and let the bills roll in! I guess you have the advantage of UFH everywhere, whereas I have rads also so need higher flow temps to compensate for them. Currently playing around with temps but 35 degC seems to be doing well for me at the moment.

Interesting everybody raves abut weather compensation, im beginning think its not all what its cracked up to be. Today flow temp of 29/30 has house nice@22, im thinking im going to switch to constant flow temp and see how that goes as weather gets colder, as if it was say 0deg it would be flow temp would be 37.5 on weather comp. Im trying running it from 12pm to8pm and see how house reacts as running in the cold of the night consumes lots of electricity. Last night shut off heating at 8pm and house still 22 at 9am.

Yeah i have went to 26 and that didn't warm house enough, going to chance this for few days, just swapped to fixed. House retains heat well and is air tight so il try running for 12-8pm. Generally nobody here long enough in morning to have house at 22.

Yeah but im thinking like keyno, gonna try fixed temp because if 30 works in lower outside temp and i run for set period and house retains heat i wont need the curve.

My point on fixed flow temp is that the wc curve doesn't know how well my house retains heat or how quick it heats up. I could set my curve that it runs at 30flow temp @ 0degrees, however, when its say 7 degree outside the flow temp will drop too low and not heat the house. I ran 12-6pm last night @30 flow. My house is still 22 degrees in living areas today. I getting cop above 5 so lots of thermal energy is being transferred to slab during warmest part of the day (12-6). Heat pump running at night is expensive and noisy. I will see how this theory goes in colder weather and may switch back to wc.

Would this be set at the tank or what?

Not all systems the same i'm sure but I don't have a clue so as simple as you can explain please :)
