I've averaged a COP 4.7 for this month (heating and hot water combined), 5 people, 4 bed 180sq.m. 1930s semi, Arotherm 5kW. Small solar array and Tesla 14kWh battery. Octopus Cosy: electricity cost just under 13p/kWh. For the battery, I'd wait as long as you can as the prices are dropping due to China's supply ramp up.

hI I want an affordable camera that can detect a snake well within 3 meters in adverse conditions. Is the P2 capable of it?

Vaillant Heatpump good I have a LG Therma V Monoblock 9 KW 60 degrees. Hot Silent Cheap Easy. 3575 euro subsidie 3075. With Rooftop Solar no Energybill.

ask any plumber , theyre shite

Climate change my Backside !! It’s called weather

Put in a new combi boiler, more than happy, will not be installing a heat pump anytime.

A useful insight to the process. We are in advanced stages of moving over with a couple of similar quotes. We haven't gotten a quote from British Gas though but perhaps we should have. I would be concerned about getting a response from them on any issues. We will probably go with the Heat Geek team as the assured nature of it does give us some comfort after all the online horror stories of bad installs and poorly heated homes. Our microbore pipework does seem to complicate matters but the contractors seem to be confident their designs will overcome it. Its that the makes us more likley to go down the Heat Geek route. They arent a large organisation like BG so, hopefully, if we need to contact them with issues we can. The downside for us with HG is the finance rate is expensive but it can be paid off at any time. For ease that suits us and means we dont have to find a large deposit just after Christmas. Thanks again for the videos.

Have you tried using it to find pipes/cables in stud walls? For example, if you drill an 8mm exploratory hole, would you be able to fit this through and articulate to peek around the void and then fit a 8mm wall plug in the same hole when you're done? I've been considering a Teslong with a 6.5mm head but it is a bit pricier and would have to go through Ali.

I've had a few quotes for a heat pump for my Semi Detached 3 bed house, Octopus £2522, Heat Geek £5300, Aira not full quote yet but estimate on website is from £6500 for a 3 bed house (probably will be more if radiators need changing). I think it will likely be between Heat Geek and Octopus. As Aira are relatively new and untested, I am reluctant to pay a premium for them. Also I am concerned about the 15 year warranty, the same company behind Aira (Vargas Group) was behind Northvolt and we know how that has gone. Having a lot of financial backing alone is not sufficient to ensure success. The Aira heat pump is proprietary and app based so in the event of the worst happening to the company, how would you control the heat pump or have it maintained/ serviced. Although the Aira is in my opinion the best looking heat pump, my head says not to go with them. One thing I would be keen to know is the servicing cost, Octopus charge £108 for cover including an annual service whereas I understand Vaillant services start from £250 -300. This may significantly reduce any savings from a more efficient system. Even with 25% increase in efficiency, I.e. say if with Octopus I could use 4000kwh @0.25 ppkwh = £1000, whereas Heat Geek is 3000kwh at 0.25 = £750. The £250 savings would be almost eaten up by higher servicing costs. With battery storage, Octopus would be even cheaper than heat geek If on intelligent octopus go. Octopus would be 4000 x0.08 = £320 whereas heat geek would be £240 which would means that the increased cost of service say £200 would be more than the efficiency savings of £80, resulting in octopus being cheapest in running costs as well as up front.

I have an ASHP & MG4, solar & batteries, and yes it does save upto £500 in winter per month, but only because I’m on a cheap overnight electric tariff. Oil is still cheaper cost wise for heating (at around 6p/unit 24x7)

Does your payback calculation take into account if you'd just stuck the money in a high interest account? I'd be interested to see how this affects things with current interest rates. Great videos BTW 👍

From my Heatpunk calculations it looks like I'll need quite a few radiators replacing. I'll get a local Heatgeek engineer to do a quote and probably British Gas in the new year. It's quite likely I'll replace the rads myself to save on some labour, I'll sound them out when they come round for the survey.

I guess it is for people who live in flats/rented accommodation or have an unsuitable roof who can't get their own solar panels.

Heatpumps are the way forward. Have your Gas Disconnected as soon as possible. 🙏🇬🇧

Interesting. The new windows for the house were by far the most expensive part of our journey to full electric. Well over twice the cost of the heat pump install. Wow, your journey took ages! Enquiry to install of our heat pump = 3 months

Interesting

Thanks for putting up some real life numbers, it really helps the slightly undecided.

Thank you for the information, I am crunching the numbers at the moment to install a 7-8kW HP on a diy basis, we already have a load of PV and battery storage and if I can make the boiler redundant that would be great. Just need to convince the Mrs to get rid of her old gas cooker and the bye bye meter and standing charge.

Wow. As a Canadian, my first thought was - THAT'S CHEAP. Before I watched through to see that there was a substantial grant off of it, but still - what YOU paid was dirt cheap. The second thought was - OMG, I thought OUR local bureaucracies were petty and stupid. (They are, it simply depends on the attitude of the local municipality). Now if out idiot PM has done something more like this than the hated "carbon tax" (Yes, it worked well in Sweden - CANADA is NOT Sweden, sadly) he might be getting less hate these days. Really interesting ... I follow Dave from "Dave takes it on" and watching real people in the UK makes me wish I could MOVE there (technically I think I can but I don't know how healthcare would work).

My take on it usvthst if you stick to the original fit your usage should deliver the kw consumption they tested however the speed rating and load are the defining characteristics to adhere to.

FYI - we went with Heat Geek. Our actual quote was considerably lower than the online estimate - about £6k less. The online calculator seems to be very approximate.

I swapped from LPG to an ASHP a couple of years ago. Having a Tesla Powerwall I can store some cheap energy from overnight and use it to heat the home. Could never do that waith gas. I also looked at all my spening on the home as an investment in my home and had has reduced my outgoings massively, along with the EV and home charging. Merry Christmas!

Very helpful.Thank you.

As the pink Friday 20% off deal is ending, I've just started with the octopus online quote and its just under £6000 for a 1990's 4 bed detached house. I don't know if they are trying to make up for the discount but it seems quite high. The octopus rep who called me was non committal about whether it would get any lower when I mentioned that I thought it would be a fairly easy install.

My oil boiler is coming up on 25 years and my annual service guy last year told me it is on borrowed time. Heat pump is high on my list of replacements options so your videos are really helpful and pushing me towards the heat pump. Next task is to convince my wife.

Merry Christmas mate. Another fab video

Thanks for a great year of fab videos. Detailed nerd filled yumminess. Keep them coming.

I recently had a replacement LPG gas boiler installed. During the quote process 3 Bosch approved installers visited and I took the opportunity to ask their opinions of air source heat pumps as our home has under floor heating downstairs. Every installer said the same, don’t go there. One even told me he recently removed 3 heat pumps due to their excessive high running costs. I also looked at ground source but the installation costs were prohibitive in terms of long payback time.

The problem is, all these heat pump installs need a grant to make them affordable, £7500, and that isnt free money, that comes from the taxpayer, standing on their own merits without a grant but installed by MCS companies,, heat pumps are not viable, the biggest issue is, the £7500 grant is stopping the heat pumps being installed at a naturally lower price, take away the £7500, the p[rice to install would dramatically drop otherwise there would be no installs, so as long as the grant is there, other people (who usually cant afford a heat pump even with the grant) are paying for those installs .. now I am talking instals by MCS registered companies, I can buy a Samsung 8kW heat pump for 2K, add another 1K for plumbing and fitting (by Joe blogs plumber) and you have an 8kW heat pump installed for about the same price as a good gas boiler, but why install for 3k when you can add 7.5k Grant and still charge another 3K plus

I am two weeks into with my Vaillant ASHP and love it. If you are considering one do your research such as signing up here! I had a good price from Octopus but there assessment of 9kw h ASHP staggering. I went with a local company which fitted a 5kw H ( it will go up to 6) and touch wood, seems to spot on.

Interesting about your DNO thing - we really haven't had a problem with that and the craftsperson who visited told us it would be fine to go ahead with the installation even before the works are done! I'm still waiting on planning; I can't see them saying no, but this is Wales - we'll see.

99% not subscribed, really? Not exactly shouldering their share of helping out here are they! Subscribing is free, commenting maybe be a chore but if it helps the Algorithm and you then its worthwhile, and a thumbs up is another zero cost return for your time and effort.

How much did the heat pump install cost 😂

I'm in a fairly new Build, with a 2 year old Boiler, and a UFH System. I still don't know if I should make the Jump to a Heat Pump or go for an Electric Car 1st. Solar and Battery system all done, but what to do next....? Keep up the Good Work and Seasons Greetings and all that to you and yours.

I would have assumed that British Gas would be the most expensive, very surprised. My boiler is 8 years old just over mid life, so I am prevaricating but also aware that the grant could go anytime.

Ive been following all your videos for the last year, I only wish BG had a quicker roll out of installation of heat pumps, currently not installing in Chelmsford, Essex

It's seems the MG 5 has a better battery technology, I have seen cleverly EV MG 5 holding up really well but I can't say the same for the ZS ev models. My car is 2021 model and only 48000km my SOH is at 90.65% which is really a shame. My 2011 Nissan leaf with no thermo management system was 82 % in 2024 before I sold its for the MG zs ev due to CCS and thermo managements but the Zs ev model has really let me down.

Thanks for this video. What made you need planning permission? ASHPs are permitted development? Did you do the application yourself (I think I'll need to do a planning application too)

I had the British Gas surveyor come round in April 2024 and he told me that they as a policy will replace all the pipe works. I told him I had no interest in having the house ripped apart and send him on his way. In hindsight I should have let him carry on with the survey and waited until the organisation got over that craziness. Sounds to me like there are some internal battles going on at British Gas that are at the very least not helping the heat pump installation part of the business.

I watched your original videos recently as I am still mulling over whether to add extra A2A to existing A2A setup or just go A2W. The A2A unit will probably be only slightly less the your final bill and also no hot water. My biggest worries about going full A2W are the fact I have plastic 10mm piping which was done when the original 1980's system sprang a leak 12 years ago and could not be located with many pipes sealed in walls and under concrete. Another re-piping probable with all the disruption. Also radiators belong in museum, so full replacement might be necessary. What paperwork did BG sort out themselves ? Not the DNO ? The paperwork for my Solar/battery system was completely arranged by my installer including G99 DNO and I just had to sign and post.

Thanks for the insights. My former landlord replaced our combi boiler with another because heat pumps are too expensive and don’t work. Upon moving my my new build home I have solar panels, lovely insulation and a gas combi, because the builders were not required to install a heat pump in the first phase of construction. All future homes on the site have heat pumps and my home has all the space needed. I appreciate any and all objective information on this subject as the noise around it is deafening. 😊

Do you think in the future that a heat pump would be able to replace a boiler without the need to upgrade the radiators , so it would have to generate a heat factor that mirrors a gas boiler .

Great to hear about the stages of your journey.Enjoying your content👍

7:38 Octopus are the same tbh. We've still not had any invoice
