- This is the last of the Heat Pump and Rinnai water heater Video Uploads, the next upload will be back to Antennas and Ham Radio Promise!
Anyway please enjoy and subscribe, the next time I upload it will be about the new MagLoop I am building..
This is not a how to, but a just for interest look at installing an Air to Air, air sourced heat pump system.
More Radio Amateur / HamRadio stuff soon..
See Dameon Hill's UA-cam Channel at / @dameonhill
Thanks for watching.
Plus. there is a good upload from heat geek with a similar title • Air To Air Heat Pumps:...

Hi MIKE, glad to see your video. Happy Holidays for you and your family. 🎇🎉 73 👍🏽
Great information all around, good to see you like it thus far.
Have a wonderful holiday, see you on the flip side. 73, N2IMB
Intersting. Thanks.
Hi Mike,
Thank you for sharing this much detail on the system. Really looking forward to the next update (especially since we had the 2 week cold snap in the UK)
We're getting almost the same system installed in our home in January 2023 (2x Daikin multisplit compressors + 7 indoor units) due to the fact that the previous owners had a terribly sized/designed air-to-water Heatpump solution put in place. 3x 4kw ASHP, 200m2 house - it fails miserably at temps under 10c outside! During the -5c temps we were using 150kwh+ per day just for heating... Mainly due to original pipework that was never replaced, as well as using original radiators.
I've seen enough USA "mini-split" videos to give me confidence of the air-to-air route that I'm going, and your initial data also helps to back that up!
Think similar to you ripping out all the pipework, replacing all the radiators etc would've been an astronomical figure.
I have just done a calculation based on the last 34 days ( this is for the two Daikin heat pumps and seven room units only and not any hot water) and I have used £6 per day giving that includes some very cold days, -12 at one point but mainly around -6.
I would also add that on the coldest days we averaged 29kW of electricity used. Average temp in the house 22deg C
Thanks for the information.
Hi Mike - fascinating. By all means do your Magloop video (love all your radio videos), but for me your heating videos have been just as enlightening. I love the honest assessment - you went for Air-to-Air heat source for space heating, but for now have stuck with a gas boiler (direct water as required), rather than jump to the full heat pump solution (and have given the reasoning ). Dameon seems very knowledge too (now following his channel). / For my situation I do find our air-water heat source pump solution more efficient for hot water than for space to be honest. Writing on the 15 December, the pump has provided all space heating to 20C, and all hot water required, and it has been comfortable for sure. But at £10-12 / day. Now this is in quite cold weather, and in the summer we have all the hot water we need for
Hi Mark, yes time will tell on efficiency and cost now sub zero around -8 for me and the heat from the system is still coming cost are around £10 per day but my neighbour who is still on the old gas system is reporting £12 per day for his Gas (smart meters) if you take into account my gas usage we are at around the same costs!
Wil be interesting to see Kwh consumption over this very cold weather. Gambio !
Yes that’s for sure.
One giant con, Luke warm water. At best, and that's in a hot summer.
Yep got to love cold showers
Happy New year Mike a bit of a diversion but well explained. I was a heating engineer many moons ago, thanks for the CPD. As you still have a Cylinder Have you and your Man factored in Solar thermal for hot water? would it be cost-effective? I have seen your tubing skills you could do the first fix to cut costs, might even be resonant.
Would a long wire work in a rotary drier looking for something for the motorhome we only do pub stopover one-nighters so needs to be up and down like Topolz elbow.
Cheers M7 HTO 27mhz H2O.
No cylinder, it was removed with the heating.
Love to see what all the indoor units look like, and how much space they take up. Can you install this in a maisonette? And...what did it all cost?
Prices vary so you would need to get pricing for your situation.
That's a lot more per day than I pay on gas in cold weather. Perhaps his house is large?
Genuine Question here and not a "snipe" but any discount on supply or installation for the you tube coverage/ advertising on your channel?. Thanks 👍🏻
Well that would have been nice but no, I prefer to pay the proper price as that means there is no issues if things go wrong.
Hi Mike, Just one question - how long will it take to pay for itself with the current charge for gas and electricity?
Not sure why this question is being asked, so I will ask you first how long will it take for you to get the money back on your boiler/ heating system? The question should be is the investment worth the results? Is it reducing your monthly/yearly energy usage? For me the answers are yes yes and yes
@@mike-M0MSN Good question Mike, ours is a new build (paid for while the floor drops out of the house market!) So not really return for me. I wasn't kncking your investment if it fits your build and your willing to wait a number of years for the return on your investment. Then cracking. 👍
@@Martin-kq9qt No offence taken, unlike solar I am not expecting to recoup the total cost of the install and I would not advocate replacing a perfectly good working gas or oil heating system just to save 10 - 25% of the energy usage. The facts are the cost of install will pay for 10 - 15 years of the additional energy prices. However if you find yourself in the situation where you need to replace your heating system, then heat pumps are the way to go.
In my case the cost of replacing my Gas system and replacing radiators and pipe work would have cost 2/3 the cost of heat pumps, so it was a logical choice for me.
🤪😀
Hi Mike how's it working out with the radio's and interference?
Zero interference atm.
@@mike-M0MSN excellent news there then 👌
What's the running costs ?
Around the same or a little less for me.. still early days
Ah it's dead easy to convert celsius to fahrenheit, all you have to do is multiply the number of firkins by the length of the groundhog's shadow then divide by the inside leg measurement of a flat earther.
and don't forget to carry the 1
Show us the maths,, cost of install us running costs, minus any gas costs saved. When is the break even. 10 years, 20, 25, 40?
Not sure how to do a comparison when the amount of water being used is not a consistent nor the price of the gas. What I can say is that it works. Find out your own costs and go onto the internet and look and see if this is better for you.
