Good to hear the pressure stabilised because I wasn’t too hopeful when it dropped off so quickly. Would be interested in the monitoring data you mentioned. Did octopus fit the additional equipment for this or did you get it done afterwards?
I installed a esp32 board loaded with espaltherma which I connected to home assistant. I also got an electrician to fit a Shelley pro 50 in the heat pump consumer unit with ct clamps around the power cables to monitor the electricity used.
@@HarjDoolno the Daikin app is very basic and gives hardly any info. You can get more from the mmi but still much more using the esp32 and Shelley. Have a look at people’s graphs on heatpumpmonitor.org and you will see the kind of info you can get.
I had to get planning permission as my heat pump was calculated to be 1 decibel over the allowed level for the distance to the neighbours bedroom window.
I’ve just had a Heatpump installed by octopus, very similar install to yours. My only concern with yours is that going forwards for maintenance - the immersion heater is inaccessible should it ever need to be replaced. My installer made a point of saying they had to position the tank so that in the future it could be changed if required. You’ll probably have to cut a hole in the side of that cupboard to access it!
1) music horrible; totally detracted from what you were saying. 2) overall it seems Octopus couldn’t plan a p…. Up in brewery. Why all the return visits - plan it and do right in the first place. 3) I have seen much neater pipe runs. Looking forward to hearing about your future journey. Thanks
Concur with the comment about the music although I did watch all the way through. It was intrusive and I couldn’t hear the heat pump when you showed that bit. Otherwise thank you. I will be interested in your winter performance.
@@kindnsartex has been de classified on the possible amount of asbestos that it might contain. Was it sampled? I have the same in my house and have had it sampled and the report is clear no problems.
Do you know if the legionella cycle uses the immersion heater or does the HP ramp to 55 degrees for this? I know the Valliant units can do 55 degrees without too much trouble as their max is 75 degrees but the R32 units have a max of 60 degrees.
I believe it heats up using heatpump to certain temp then tops up to 55 or 60 as default with the immersion. I do however have a problem with this as has never managed to complete. I did report this to octopus and had an engineer visit but still get the dreaded AH-00 error. I will do some more investigation and tweaking but may just disable the legionella cycle.
@@kindns That's a shame, hope it gets sorted. I know Heat Geek have a video on legionnaire cycles but haven't watched it. Assume the regular HW heating cycle doesn't involve the immersion?
My Mum had the same issue for the first three weeks of her install. Turns out the immersion that was fitted was the wrong one. It couldn’t reach the target temp. Octopus swapped it and she hasn’t seen the issue again.
I found getting water hammer and octopus keep trying all sorts to fix it, but problem still persists today and my initial install was start of April. Not really had the rads on, just the hot water. When they did come on they felt lukewarm warm so hope they get hotter in the winter or we will freeze to death.
Thank you for sharing your specific journey. Neat jointing work and the final job looks really sound. At the end of the day, any scop over 3 will be good if you close the spark gap with gas to the point it is cheaper than. Will you be montoring the scop/efficiencies and reporting on those, too, for us?
Yes going to be monitoring my scop. Just find the Daikin ones on the mmi not particularly accurate as round up the usage. So far it’s reporting 4.66 on the heating and 2.7 on dhw. I’ve been setting up home assistant and got the esp bits to install in the heat pump when I’m brave enough to get accurate figures.
Hi Stuart, Thanks for your interesting videos. I'm just waiting for my design to come from Octopus and then (hopefully!) we'll get a heat pump in before the cold weather arrives in the Autumn. Your videos have been really useful, showing me just what to expect. Cheers, Phil
We’ve been running ours for 6 weeks now and it’s great 8kw Daikin very similar to you we ran the pipes parallel to the drainpipe and followed the roofline into the loft they did a great job. 👏
I like your videos they were very helpful, can I please ask what was your quote less the BUS. I am just waiting on the survey and have to say looking forward to having my ASHP installed. It be good for your next videos to show how to work the system and adjust the settings etc
The total cost once the BUS was taken off is £950. I did have to spend about an extra £500 on removing asbestos from the cupboard ceiling and getting planning permission. I only needed this as the pump was scored at 1 decibel over the allowed limit when closer than 6m to my neighbours bedroom window.
Good vid, did they give options for the external pipe routing, interested to see if flow and return can enter via loft and drop to airing cupboard, rather than longer wall routing. Interested to see your results a and spend
Good stuff. May I ask: Did you need all radiators replacing? Were they flexible in radiator size and location? Did you have choice of hp location? What controls will they install do you know yet? What size is your existing radiator pipework sizing; it looked maybe 10mm? What was your heat loss calculated as and what hp size resulted? How long between survey and install? My fast quote just came in at 4200 so I'm wondering why the difference. Thanks for the videos; Very helpful 👍🏻
Just 4 rads were replaced. They are a bit flexible as long as they meet or exceed the heat loss for the room. In my kitchen they were originally going to add a second radiator but would have required more pipework so they agreed to put in a wider K3 one instead. My total heat loss was worked out as 4208 Watts. They have fitted a 4Kwh HP. I had the survey last August but due to lack of fitters couldnt book me in until this week.
Twofold really, one to do my bit for the environment and secondly financial. I believe as long as I can get a scop over 3 and being on Octopus Agile it should be a fair bit cheaper than gas. It also only cost £950 after the grant. Although did have to spend about £500 on planning permission and to remove asbestos from the cupboard ceiling.
