This video covers the 30 days since installation of our Vaillant 7kW Air Source Heat Pump here in the UK. A Heat Geek assured installation by JMR Heating & Energy Ltd in July. This data covers August and rolls into early September where the heating kicked in for a few colder days.
We have one minor issue which is explained in this video in more detail. The previous video covered the 6 day installation and costs can be found here: https://youtu.be/yo_-V3fH47o

Great overview video John. Would be interested to know if you've looked into if it's possible to integrate into Home Assistant and if so,what benefits that would give?
Great video as always – those Valiant systems look very nice.
Did you get a quote from Octopus Energy – – Daikin heat pump , Daikin compatible water cylinder, Any necessary new radiators and upgrades, Any necessary plumbing and electrical work
Labour and workmanship. Quoting just under £2000 (following the increase of the grant to £7500) for our 4 bed detached house. Which seems very cheap compared to your 15k bill ?
Hi John. Great video, again ! I have 2 questions: what is the distance between the heat pump and the fence ? It looks less than 1m for me. Isn’t it maybe too close, so that you will have recirculating the cold air?
Second one: did no-one recomend you to use an deaerator, like spirovent or zeparo ZU? I am thinking of installing one, just to be sure.
This country is finished, Tories u-turning on their green pledges and schemes made to make their mates rich. How does one factor in a green system when they keep taking away incentives and deadlines. When will it end??
Hi John, Great video, but could you maybe add some more information for the ASHP monitoring with EmonHP. Dis you buy the level 3 kit and then get it installed or purchased with the ASHP? I am also interested to know more of how it connects up. I like you want to have more monitoring available to view and keeping track of how it is working.
I’ve instited octopus run my pipes internally
Still waiting for them to get back to me.
This has been really interesting John for a number of reasons. We have been looking at ASHP but had a few concerns due to the plastic microbore pipe. Watching your videos has reassured us that it will work as our house is 2018 and very well insulated, plus we have already installed large radiators to run our system at a lower temperature. Also by astonishing coincidence, JMR Heating is local to us and will be doing a survey.
I still think the clearance in front of the heatpump is questionable. Certainly Octopus Energy would not of installed it there, because of the possibility of recycling the air as that will lower the efficiency.

Thank you John
What led your installer to the conclusion that the buffer tank is not necessary?
What happened to LLH? Reasons for removal?
Just looking at the clearance distance to the fence , I’d say there probably be an issue once the outside air temperature drops and the re circulating air caused by the fence ,starts to cause freezing on the coil, which will cause the efficiency to plummet. Will be interesting to see.
I am thinking of adding a Valliant heat pump to my home and noticed you have an Eddi, are you using the Eddi to get the heat pump to heat the hot water wit the Eddi relay or is the Eddi simply heating with the immersion?
I have read your comments re the distance of the unit to the fence – I fully expect you to have issues once the ambient drops to zero and below.
What a monstrosity..
Until the price of electricity drops in relation to gas, I don't see why anyone would install a heatpump in the UK. Electricity is 3x – 4x more expensive than gas so a COP of 3 – 4 is basically the same cost as gas. That is until you get into winter when you need the greatest performance out of your heating system. A gas boiler is unaffected by outside air temperature but the COP of an ASHP is greatly affected in a negative way. COP of less than 2 is not unheard of in sub zero temps. Until the price of electricity is decoupled from gas there's absolutely no point, unless HPs start producing COPS of 5+ down to -10 degrees C.
I would expect better lagging in an unheated loft space like that.
No wonder theres not been another update, geezers probably frozen solid along the ASHP with those clearances from the fence, no buffer, massive external pipe run and prikary pipework size.
