How I fitted an Air Source Heat Pump ASHP: Samsung Gen6 5kW

This is my experience self-installing a 5kW Samsung Gen 6 Air to Water Heat Pump and a 150L hot water cylinder in a 200-year-old terrace house in the UK.

*Clarification*: In the video I mistakenly said the total floor area of the house is 30m2, however this is just for the ground floor. Total floor area including both ground and 1st floor is 70m2.

*Heat loss calculators: *

**Note: I'm not a professional plumber or heating engineer, this video is just documenting my experience, it should not be used as any sort of instructional video.**

Im a heating engineer with over 20 years experience & im not sure what you do for a living but i would seriously consider a career obviously if the moneys right in this as you've done a great job here & should be extremely proud. good luck with what ever you do in life

Much more informative than a lot of videos made by professional heat pump installers that I've watched.

I am plumber most of my profession time I have spend for electrical heating installation and repair work . Now I am doing course for heat pump installation . I like your video cause its give me confidence for heat pump course . good luck

[normanboyes]

Glyn first of all congratulations for achieving your install. You have likely done a whole lot more research on the subject than many ‘professional’ installers and you clearly have a holistic knowledge of the principles, theory, controls and instrumentation as well as the ‘geekery’ ability to get it all ‘talking’ to each other. I really enjoyed the video and look forward to the update.

This is fantastic to see the whole process start to finish and all the considerations you took. That data capturing stuff should be standard for everyone as it must be so good for people to see the actual COP over time. Very jealous of your skills and that you were able to do this yourself. Wishing you a very low cost and warm winter and looking forward to seeing your results in Spring :D

Just finished fitting a 5kw air to water heat pump to existing boiler. I bought the heat pump second hand for £180. It comes on for 4hours a day 10 to 2pm as the 6kw Solar array is at its peak at that time. I don’t have the knowledge to fit a cylinder yet but I will do by summer. The heat pump is mounted in the loft so no one see the condenser. I’ve made so many mistakes but it’s a learning experience. My system is way simpler than your system it only consists of a two way motorised valve, automatic air vent and that’s it. All prv, expansion vessel and safety related stuff is in the vallaint condensing boiler. It’s working dude just tweaking system and balancing radiators now and then. Total cost around £400 to £500 not including solar. Your project is on another level dude, you are one smart cookie 👍

Great works and enthusiasm, all works well planned and executed.
It's quite funny when someone not in the know usually sees the plant room they comment " what the hell is that mess "
Anyone who has some knowledge usually comments " thats neat and well planned ".
One thing i noticed is regs require 2 x 2 port valves for safety resons.When 3 port is used you must still have a 2port valve with safety controls and manual reset wired through it beween valve and pressurised cylinder.

Always nice to see someone having fun with a pipe slice.

That's a really nicely put together video. Good pace, good amount of content and some nice pauses as you dive into the details that are most interesting. Great work Glyn (and army of helpers including a very patient camera person :) )

You're a skilled man Glynn and that's a beautiful family you have there

[alanlee]

Glyn, well done, this is excellent information and very well presented and filmed. Fantastic to see the whole process and the challenges and your honesty, I love sustainable devlopment and I'm very impressed with your skills and abilty and look forward to seeing your report in the Spring 🙂I wish you good luck to you and your family in all you do and your future career.

Thanks for this great video Glyn. Open energy monitor is a good thing showing how well heat pumps can work. I think your work is having an impact on decarbonising heating in the UK.
Also you've given me an extra boost with trying to do my own heat pump install. I did the heat loss, radiator spec and pipe size/head loss check using heat geek training. Now I've learned to solder pipes and started upgrading rads and pipe work. I'm thinking I'll range rate the boiler over a cold spell to validate the heat loss and flow temp to help select the best matched heat pump. If only there was a way to DIY it and get the grant!
Your video also made me want to move to Wales and go rock climbing!

[johncantor]

Excellent video Glyn and great work. Well done for doing such a well thought through job. We are of course all looking forward to seeing your results.. it will be very interesting.

It started out with me thinking that I might do that, but as you progressed in the work I started to have doubts. Excellent job young man, all the best to you and yours.

[hughelgar]

I thought, he's a climber. And it turns out you are! I'm installing an ASHP in a new build on my property near Loch Ness, but with underfloor heating. Your vid is very informative and the paintings on the walls are intrigueing!

[mrpingen]

I picked the correct video to watch here for sure. Very detailed and thorough.
I am looking at adding a heat pump to an existing vented thermal store system already heated by; solar PV immersion, wood gasifying stove, gas condensing boiler and mains immersion (as a backup). Your reply to comments has also been useful regarding integrating to a vented system with a heat exchanger. Thank you. Looking forward to the next video.

30m2 for a 2 story, 2 bed end of terrace with an extension? I doubt it!!

But impressive work.

Edit: I've just seen in the description that youve addressed this and it is in fact 70m2.

[hedleypepper]

Bless you my son.
I've been doing a lot of research.
I see no reason why a heat pump should not be a DIY install. The pump itself is literally plug and plumb and play. Even though service is likely a job fir an expert.

[johnb]

Very impressive Glyn, love your diy skills and work ethic, hope you have a toasty house this winter and the system performs as you expect, 👍

[michaelridley]

Came to this after watching your winter results video. Amazing job, well done!

[JackButlerVideos]

can't wait to see the winter tests!
