Installers Said It Was IMPOSSIBLE | The Ultimate Heat Pump Challenge

[@KingzyPin]

Well done guys! Had one of your trained engineers install our HP near Bristol…it’s amazing! Simply!

[@terryrigden4860]

Looking forward to seeing how it goes in

[@mattundercoat]

I don’t think you mentioned flow rate. Do you have to make an educated guess when the pipe work isn’t visible or is there a way of testing it?

[@carbongrip2108]

Why not go with a heat pump mini-split a/c system? Get the benefit of both heating and cooling. Unit goes on the roof in the same spot and you only need power. No need to play with water or have radiators in the way of your furniture.

[@umark6695]

If he's the Co founder and CEO of heatgeek a) Why is he consulting the builders plumbers about heat pumps? b) Whid did he find heatgeek whilst searching on KZbin? Sorry just my cynical side!

[@egocd]

a) He's a business/software guy, not a heating engineer. b) Heat Geek already existed, but he helped expand.

[@Umski]

It is a bit puzzling, you’d think that they might have held back to get some Heat Geek input before finishing the property but then again it makes for an interesting case study 🤔

[@jonblacklock1052]

I can’t remember whether I’ve asked this before. Vaillant & a couple of other OEMs have integrations to heat batteries like Sunamp. These have a better & more compact form factor than cylinders. In addition they are low loss. Would a Heat Geek consider one of those in place of a mini store?

[@jonjohnson2844]

Good to know a heat pump isn't a total waste in a old terraced like mine, I think I'd probably be more inclined to invest in solar first as a fairly heavy electricity user but I suppose that only makes a heap pump make even more sense. I'd definitely be sticking a roof terrace on that extension though!

[@tlangdon12]

A heat pump, even on cold winter days, should take 2kW of solar energy and convert it into nearly 8kW of heat for your hot water, so it's much more efficient that a Solar diverter that dumps the solar energy into an immersion heater.

[@robinbennett5994]

Solar will have a better ROI, but a heat pump will save more carbon - so it depends on your goals which you do first.

[@Biggest-dh1vr]

Solar offers payback against whatever fuel you have, so I'd treat that separately from the heat pump.

[@KavanOBrien]

Would be nice to see a video using ATA rather than always seeing ATW Would also be nice see a comparison not only installing cost but running cost .

[@derloos]

2:15 ...and also, this whole house has been renovated top to bottom, so we can't open the walls. How tf does one go about renovating the whole house and not doing first things first, such as real actual plumbing!! Mindblowing, that.

[@egocd]

Because people focus on making everything look pretty over all else.

[@JohnThomas-ey1hx]

And why not insulate the walls while he was renovating?? Not the best advert for HeatGeek when the CEO didn't consult Adam or one of his many trained up engineers for advice and get the place insulated as part of the renovation work. Even if he is doesn't understand heat pumps, surely he understands heat loss and the value of insulation whatever heating system you use. I'm just a bit bemused by the whole video.

[@Sam-mb1yk]

​@@JohnThomas-ey1hx He's new to heat geek so probably did the renovation before joining

[@longline]

Yo, distance to the windows and that, r290? I'd like to hear specifics in the follow up. Some real world clarification, re a 5m wide property.

[@simonnicholls3650]

No, the Ultimate is a pre 1919 Detached house...Now that's a challenge for you.

[@LyubomirYanchev]

14:13 what’s the software they are using?

[@Biggest-dh1vr]

HeatGeek own I think?

[@mihairachita174]

1.Honestly guys, not every house have an extension to get the heat pump on top of the extension and also 5m each side of the heat pump. 2. I bought a semi detached 3 bed house, have had a survey done by octopus and the only place we could have the heat pump was 9m away from the house, 1m away from the boundary ,nothing within 50 cm around the heat pump and nothing in front of the heat pump within 1m . Basically in the middle of the deck. AND can't be installed on the deck !!! So we have to destroy the deck to get a pump?and pay someone to dig around 70cm channel for the pipes , around 9m long?! and to get the cylinder in the loft, the pipe work from the heat pump to the cylinder can't be more than 21 or 23 m (can't remember for sure). All this are a NO NO for us. Forgot to mention, we installed solar panels before thinking about a heat pump(4.35 kwh array, 3.6 kwh inverter , 10.8 kw batteries. So now a heat pump would make sense. We wanted all this because we want to get rid of the gas boiler, change the cooker to an electric one(so no more gas in the house) and we could move the american style fridge freezer in that corner. Still waiting for a solution.

[@tEXKiKos]

hey. check out KERS MEV ASHP Hot water cylinder. it will work better for what you are trying to do. I see they are also doing option with coils so maybe you could even plug heating from it. Not sure if they have ever done it this way before, but you can also include on the flow pipework Heater Sadia Amptec electric heater to top it up to replace heating circuit or just go with electric heating... . you are welcome :). let me know if you went for it.

[@Teslabull]

I guess we will need to build a new house to install heatpump

[@danielduggan7126]

Just keep the gas and be happy....and warm.

[@Biggest-dh1vr]

HeatGeek installers (or even others) may have different ideas for installation?

[@chester6343]

Notice that the owner is obviously caked because that probably helps 😂

[@robertszynal4745]

I can't help but feel that something like a communally shared ground source heat pump will be one of the only solutions to get off fossil fuels for most normal terraced housed. That would be a major challenge.

[@longline]

Literally about to move house in London, this is the data that I need. Second thought... Aren't all of the heat geeks over worked and over booked? Is there a point where further promotion just makes your installers pressured and sad?

[@gibbodive140]

Constructive question.... how keen are the manufacturers service engineers about getting onto a roof for servicing and repairs ? Is that or could that be a problem ? Thank you

[@johumm455]

for an aircon it is pretty common to have the outdoor unit somewhere on a roof So no probs at all

[@WyndStryke]

Talking about impossible, how about my middle-terrace maisonette with no land? Where does the external unit go?

[@johumm455]

on the roof or on the wall in a PVT system ?

[@WyndStryke]

@@johumm455 That's interesting, never heard of one of those before. Are they on the market, or at the research stage?

[@Beni10PT]

I thought an old appartment would be the impossible challenge! :)

[@tlangdon12]

I think apartments are harder than terraced houses because you still have the same lack of space for a cylinder, but greater problems with noise and the space to locate the outdoor unit.

[@jordanbarnes7671]

[@jordanbarnes7671]

[@jamesdaw131]

I’m intrigued by that location for the heat pump. What are the rules? 5m was mentioned? Also any idea what sort of strength of support is needed (I have a sloped roof so would have to build something to make it work?

[@Liam_Hirst]

It will be wall mounted on a bracket

[@jamesdaw131]

@@Liam_Hirst interesting. The challenge for me would be how does the engineer service it… I don’t have the easy access flat roof. If I could make it work it’s a game changer mind as I have no where to put the outside unit really.

[@Liam_Hirst]

@@jamesdaw131 yes you would need access for servicing We’ve fitted a few on brackets but never anything out of reach yet

[@bramptonkendell]

Maintaining existing microbore heating pipework AND use 45 deg C flow temp and frequently starve heating circuit for the domestic hot water tank? Does not sound like a recipe for a comfortable house in the winter.

[@Biggest-dh1vr]

I can't see the hot water needing to run that often or for that long though, with the Store size, except during showers or heavy hand dishwashing? The pump matches the heat loss with the given emitters at that temp (with some hand-waving), so no problem there?

[@aclelland]

Funny thing is that I used your website earlier today after watching another one of your videos. Got quoted nearly £15k for an install. Not your fault, the equipment is not cheap and well trained labour isn't either but even with the government grant I think I'll be sticking with gas for the foreseeable future.

[@edc1569]

Yeah no way that will ever make sense.

[@Biggest-dh1vr]

Other installers are available!

[@davetaylor4741]

My question would be why. For a start plumbing and electrical are done when the place is gutted. Not after full restoration. Secondly is the cost. The house shouts money, and you have heat geeks on tap. Money can buy a solution to most things. But for the average punter, not so easy. Then you have a flat roof extension to sit a big ugly box on. I had a similar style house in a terrace for many years. It wouldn't have complied there. And my biggest issue with heat pumps is constant running and constant temperature. I like to turn on on off with a timer. And I like rooms all different temperatures. Heat pumps work. With enough money that could be almost anywhere. Would I want one. No.

[@Biggest-dh1vr]

Presumably with modern controllers offering different temps at different times, and limiting flow rates you could do what you want with a heat pump? Though it might be cheaper with a more consistent heat?

[@clarkfinlay78]

wait if it wasn't for the large flat roof and the neighbours bathrooms on either side giving you more than 5 metres for the mcs020 this would have failed both the 1m distance and sound?

[@affieuk]

The HP is wall mounted. Although not sure if that would be viable for service engineers? I think I've seen a video of a wall mounted unit raised quite a bit of the ground.

[@Teslabull]

Got a 5 bed 1920 terrace, really want a heat pump, octopus surveyor came said too much of heat loss, so we can’t install. asked British Gas, said no entrances in the backyard, heat pump not allowed to go through front door.

[@TheRonskiman]

The thing with Octopus and British Gas is they want the easy jobs, try an independent installer.

[@metalhead2550]

What did they say your heatloss was? Because Octopus have recently just announced the Cosy 10 also, as of a few days ago

[@Biggest-dh1vr]

​@@metalhead2550is the Cosy 10 much cop (as it were)?

[@K-carbon]

For sum one thats poor at maths now very poor is the heat geek course a non runner

[@andrewmillwardwatford9410]

Not at all. The support is excellent.

[@jamesdaw131]

Hang on. He is the heat geek ceo and didn’t know how to get a heat pump…?

[@Biggest-dh1vr]

The Mini Store only became available earlier this year. Installing a hot water cylinder in the space available would've been tough before that? Presumably he renovated before joining HeatGeek?

[@tvtalkshowshigh]

While London might be full of houses like this, the bulk of the properties across the UK contributing to that statistic are very different from this. They're perhaps also occupied by people who consider heating infrastructure a higher priority than a decorative plant shelf. I admire what you folks are doing, but it's disingenuous to present your approach as being for the majority. The demographic you target is distinct from, but just as constrained as that served by the likes of Octopus. Why not just be honest about the problems you've done a great job of solving rather than making grandiose marketing claims?

[@tEXKiKos]

ROI on the investment, never. Its an hobby, not a strategy for that kind of building. Saving 100 a year on electricity (compared to gas cost) cost when you need to fork out 10k do ASHP. Shower flowrate barley will scratch the surface. two people cant shower at once and you will need to wait ages for buffer to recharge. all great by too many sacrifices.

[@josephmcmahon7470]

Edited yet you're still going for an attack of "two people can't shower at once".

[@andrewmillwardwatford9410]

I think you make some fair points and almost all of the customers I have changing for heat pumps are doing it either for the advantage of the Grant and or a desire to reduce their carbon footprint. But the video is on point because so many people living in this kind of house want to make the transition to reduce their carbon footprint and generally this is not been easily achieved.

[@tEXKiKos]

@@josephmcmahon7470 of course. how many seconds of sustained 42 degC heat pump can provide without massive water cylinder and electric immersion heater inside? you are trading of useable apartment/house space which is not cheap. if you need to use electric immersion heater to top-up water heater than you have defeated a purpose of ASHP.

[@TheRonskiman]

​@@tEXKiKosPerhaps you should watch the video they released a while back about the combi cylinder.

[@MentalLentil-ev9jr]

@@tEXKiKos Even if a top-up immersion is needed (is it?), it wouldn't defeat the purpose of a heat pump which would still be more efficient than an immersion on its own, plus the heat pump would still do the heating which is the major energy consumer. An electric shower is always an option. It's also worth pointing out that within a few years gas boilers won't be an option, so the choice will be heat pump or 100% electric heating. That is the real choice for anything past the short term, a gas boiler is only a temporary solution.
