Heat Pump Installation Secrets EXPOSED

[@JOOI525]

It's one of the best videos I've seen on the 'need to know' before a ASHP installation. I think it's a perfect watch for my wife before we have ours fitted early Feb. Thanks and look forward to the rest.

[@JonathanTracey]

Thanks glad it was useful

[@BrianTootill-e7j]

Thanks again JT for a really informative video that gives great pointers for someone like myself who's hoping to get a heat pump installed later in the year. 👍

[@JonathanTracey]

Hey Brian, glad it was useful, planning for 5 videos in this series, hope to pass along some things i have learned along the way

[@BrianTootill-e7j]

@JonathanTracey Hi Jonathan, I'll look forward to watching your up and coming videos when you release them. Any useful information gives me more time to get my questions ready once I can move forward with getting a heat pump installed. Thanks again.

[@JonathanTracey]

any time, glad it’s a help

[@johnbell1859]

Thanks Johnathan, good video.

[@JonathanTracey]

Glad you enjoyed it

Hi JT. Great idea to have this series looking at the things to consider before getting a heat pump. I’m at the planning stage and my preferred, and only realistic, location is the other side of the wall where my boiler is so not much distance for pipe work into the house. The outside space might be a squeeze with only 1.5 metres from house to fence. I hear what you say about clearance but I am encouraged by another KZbinr John Tisbury who has an almost identical space to me. His ASHP works fine with a SCOP of around 4.2. So I might be okay. Looking forward to the rest of the series.

[@JonathanTracey]

Thanks for the kind worlds, with regards to space, i think 1.5 is more than enough so long as there is a flow of air to carry the cold dense air away

[@jamesp.1784]

Thanks JT, this is a big unit, and given the clearance needed, is it possible to wall mount it? Front and back of my house is not an option. On one side, I have a driveway, so clearance isn't guaranteed, the only remaining side of my property is totally unused but there is a 6 foot boundary fence about a meter away from my house. Would it be possible to mount the unit on the wall just above the height of the fence to achieve the clearance? Do they have to be on the ground for ease of servicing? Thanks

[@JonathanTracey]

yes they can be wall mounted and yes they need servicing so you would need to discuss with a surveyor. could you place it behind the house but not connected , eg i. the garden and run pipes under the ground?

[@jamesp.1784]

@JonathanTracey thanks, that's interesting.. a garden or wall mount would suit me. 🍻

[@JonathanTracey]

I was just seeing a post on Facebook, if ys more than 6 foot off ground servicing needs scaffolding, adding to cost

[@jamesp.1784]

@JonathanTracey Thanks for the advice. At least I know it is a definite possibility🤔

[@davidsteele3037]

A very informative video. Can the outdoor unit be further away from the house than 300mm? Finding a suitable location in my garden may be a challenge.

[@JonathanTracey]

yes i believe 300mm is the minimum, but have seen the half way down the garden

[@colingoode3702]

Locating the HP outdoor unit is my biggest barrier to having a HP system (A2W or A2A). Even though we have a 7m deep front garden I definitely wouldn't want it out the front of the house. Both side walk ways down each side of the house are only 1m wide so they are a no go & I wouldn't want it facing our patio or up against our conservatory in the back garden either. Think I'll be sticking with my gas boiler for now - & that's coming from an HVAC product manager who's been involved with all sorts of commercial & domestic Heat Pumps & A/C for 45 years. My son has recently had a 10kW Daikin R32 HP installed in his 1950's 3 bed semi. He has a massive rear & deep side garden so location of the outdoor unit was not an issue for him. It's a big single fan unit sized to allow for a future extension & a HW tank in the loft. He had some issues with the install but since the house is a "fixer upper" he can sort them out when he comes to renovating & decorating. Wood burner on the way as well I think. The Octopus install took 7 days & they were without HW for 5 days. Not great with a 2 year old in the house but it's working OK now. The best bit was that after the BUS grant, rebates & discounts from Octopus to reimburse them for the install issues & inconvenience the install was pretty much FOC.

[@JonathanTracey]

sounds like it all worked out, with regards to location, you can ask them for recommendations and your not obligated to go ahead

[@nervousfrog101]

Just as a matter of interest when running at a steady pace whats the lowest power you have seen your 6kW draw, my 8kW seems to run at a minimum of about 400W it does sometime go a little lower as it shuts the compressor off but 400W seems to be about the minimum?

[@JonathanTracey]

The lowest is around 192w when it’s basically idle.

[@_Dougaldog]

I have the same unit as Jonathan the EDLA06E2V3 I run mine using 'flow control' as opposed to weather compensation, where I set the flow at 34C or 36C as needed. Like you during warmer periods (above 10C if I remember) lowest continuous draw averages 400W, currently using a steady 566W at outdoor temperature of 5.2C. When 'off' in App' (standby) it sits at 10 or 14W. At the moment it runs 24/7 and used 14kWh over last 24 hours, average temperature outside @ 2.5C. Livingroom 20C average, bathroom 22.8C, Bedroom 18.9C, so nice and comfortable throughout. Coldest day on 11th Jan, lowest external temperature was -5.5C and unit used 29kWh over that 24 hour period. During which it ran @ 17 defrost cycles.

[@JonathanTracey]

Yeah cold days were brutal, I run in weather comp, coldest day was around 24kWh

[@_Dougaldog]

@@JonathanTracey One thing I've noticed when looking at other Daikin 6kW units is just how predictable they seem to be. My Carnot estimated COP for 11th was @ 2.7, my SCOP to date (11 month period) is 4.05 according to Daikin control panel data, unfortunately I don't have an MID flow meter installed to verify these but I've no complaints as yet regarding energy usage nor heat output.

[@JonathanTracey]

@Dougaldog i agree it just does its thing reliably every day, can’t ask for more

[@Dannyy802]

Hi there Daniel from Manchester. If we get a heatpump will the exterior fan unit give off heating as me and my fiancee were contemplating moving the rabbit hutches next to it for exra warmth.

[@JonathanTracey]

no heat pumps push out cold air, so don’t put your pets near it. Air conditioning units push out heat but you generally use them in summer when pets don’t need heat

[@Dannyy802]

@JonathanTracey well maybe if heat pumps ever improve we mabel to do these this at the moment there seems to be so many issues with heat pumps.

[@JonathanTracey]

@danny no issues i can see, and don’t wait for heat pumps to exhaust heat, that’s going to need a change in the laws of physics

[@Dannyy802]

@@JonathanTracey At the moment there are too many issues. Costs of upgrading everything and the water isn't hot enough. It would of been nice if the heat could be recycled to keep the rabbits warm, but the costs and upheaval associated of the upgrading of insulation and bigger pipe work, leaves a sour taste in one's mouth.

[@_Dougaldog]

@@Dannyy802 How hot do you want the water to be, anything over 50C will scald you, and my 'low temperature' heat pump will push it to 60C without resistive heater.

[@lesmarston7709]

I was going to get a heat pump, we got octopus out to do everything in October 2024, end of January and not a lot further on, octopus did the survey, said I needed certain things doing and they would sort it out, they just never happened, even though I have had lots of communication from them. Unfortunately my gas boiler was on its last legs and that is why I was getting a heat pump. Now the gas boiler collapsed and was unrepairable, because of the time it took I had to get a new gas boiler. This video is a very informative one, but please really find out how long things will take. Although originally I was told a couple of weeks. Not correct, that was octopus sales team.

[@JonathanTracey]

sounds like they dropped the ball, i can only give you my experiences, from survey to install was about 12 weeks. i had to take care of a few items myself to be ready but other than that it went smoothly.

[@TheRonskiman]

I don't think the next episode will be out in time for me, heat loss survey 9am in the morning.

[@JonathanTracey]

good luck, let me know if you get any questions

[@alimack5489]

It’s really not rocket science, take your boiler run it at 40c flow temps for CH (if you have a combi) and see how you get on, run it 24/7 is your house comfortable?

[@JonathanTracey]

and it will cost you an arm and a leg, there is a reason most people heat in bursts, it’s because it’s too expensive to run a boiler 24/7

[@alimack5489]

⁠@@JonathanTraceyI agree mate, but it gives an idea very very basically in terms of compatibility, that’s the worst case 40c with a heat pump.

[@JonathanTracey]

I’m seeing my flow fluctuate between 33 when it’s mild outside and 48 when it’s -6. Do you know if boilers can weather compensate, don’t know if that’s possible
