Very interesting to see this Roger Guy started at Bosch here in this video when they were developing what pumps over 10 years ago. Now he is advising its possibly a car crash in slow motion, after years of seeing development and his first hand experience with heat pumps. This guy now speaks the truth advising against them in his new videos, as he did spend years with them! Fair play for his honesty, and his predition is looking quite accurate here.
@@ChazWyvern he was ahead of his time, not right :-) Heat pumps are nice for the Ritch, who want an air-conditioning anyway. For the normal person heating will become a luxury. It will be a total mess when people are going to heat their flats with wood out of desperation.
I am ridiculously jealous of that dirt. Like damn. I have this lovely red clay with a healthy dose of flint where I live and I have never seen a ditch cut that pretty.
It's really tough to see this as a realistic choice to be retrofitted to more than a fraction of a percent of existing housing. Perhaps it would stand a chance if the government forced builders to incorporate it into new builds.
Agreed. Also a problem when the usual housing developer suspects cram in as many houses (not homes) into as little space as possible leaving no useable gardens for GSHPs. However, GSHP should be required in 'luxury' housing developments surely, along with solar and battery storage as part of the design. For new-build rabbit hutches, shouldn't ASHPs be specced in preference to gas? British house builders are frankly bloody dinosaurs.
£15,000 for each house to convert from gass and you know your annual bills will be way higher to pay for the system that runs into multiple houses its going to fail in the uk when no one can afford it
The reason behind a reverse return piping configuration is to equally balance all loops - first in last out theory - by balancing loops you don't have flow in just a few of your loops it balances all - keep all lengths within 5% of each other
So it's nothing to do with geothermal heat, but a bore hole insulation up to 200m is still collecting heat from the sun? I'm sure there's some level of geothermal energy at that point, even if it is only 1-2c.
Great video but note flow and return pipes should not be insulated, they form part of the collector system and there is always a net heat flow into both pipes which are both colder than the surrounding ground at 1m depth. In a system designed to MCS standards the return must always be above freezing and the flow is just a few degrees below that. Given the thermal conductivity of PE100 used for the pipe material the flow pipe surface temperature will also be above or around freezing so there is no danger of freezing in a properly designed system.
I don't understand why the pipes to and from the field have to be insulated. Why not separate them from one another in the trench and count them as part of the system that's in contact with the ground?
Question for you Roger Bisby, do you know if a house (new built) doesn't have a garden area can the compact heat exchanger be put right within the footing of the house, i.e. right withing the footings when the foundation is being dug?
Skill builders roger, must look back at this and laugh, at how he did such an advert for this sort of product. He never said in his vids on skill builder, that he once promoted heat pumps, that now he does not like too much.
Same here in the USA...gas is dirt cheap....for now. Thing is gas isn't available in very rural areas and it is there that I see the huge advantage of ground source heat pumps. I suspect the same is true in the UK. Is nat gas not readily available in Sweden. You Swedes always seem to do everything with efficient machines...whatever it is. I admire you guys for that.
Why insulate the line with the flow to the house? Ground temperature is ground temperature. I would double insulate the cold line flowing from the house instead and keep them well separated.
1:05 This system is NOT using the sun energy..... (under 1 m deep) If there is no sun a whole month example winter groud covered with snow , even then it is working because it is geting the earth heat. Otherwise it is a good system.
I like hi-eff gas...gas is great...it's what I use. Question is...what do you do if/when gas prices skyrocket? Then there is still remaining the question of what to do about A/C? Here in the US gas is cheap right now, but expected to go up as demand for this cheap fuel rises.
GSHP 1:3 or 1:4? In my view the same area and budget, if devoted to PV, would earn FiT all year round and 20 years tax free is better than seven. RHI has a kind of biblical sense of foreboding perhaps?
“WHAT” this don’t sound mega expensive, does it. All this instead of just having a small gas boiler. You seem to have changed your mind all of a sudden. The trust I had in you seems to have gone.
Advanced system, for 200-250 house shouldn't cost more than 10k Pounds, everything above that is a scam. Also remember that this type of heating uses approx 8-10kWh of energy p/day. So the electricity bill will be approx 550 pounds more p/a than usual.
Ok, so one unit of electrical input generates 4 units of heat energy, so electricity at 15p kw/h, get's 3 heat units. Gas is about 3p kw/h, so 9p for 3 heat units. That looks like a very expensive system to run, plus the significant installation costs of £10k????
@@amphibiousmarineinc NO DISPUTE REGARDING YOUR CLAIMS. However, will this in-ground heat collection system work if you have 12" of snow cover for a month or two? Waiting for your reply & THANK YOU. Respectfully, Ben

Step up and force the UK government and developers to insist your tech is designed into new builds. You could start by phasing out the production of gas boilers
Heat Pumps still rely on "THE BURNING OF FOSSIL FUELS"! Where do you THINK the electricity comes from to operate the compressors and pumps? It comes from coal fired and gas fired electrical generation plants. Plus you loose a high percentage of electrical transmission line losses and transformer losses. So it all depends WHERE you burn the fossil fuel - at the electrical generating plant or your high efficiency gas fired furnace and, of course, costs considered.
I recently serviced a client that has a lot of money but is a 'greenie'. He has 14 heat pumps in his "house". I replaced the compressors in three of them. Not only are these repair costs high, he pays $9,000 per month for electricity. Solar, yes. But just as important, insulation, insulation, insulation and watch the glass exposure.
It's still much cleaner. Electricity demands are low in general, and very low compared to electric baseboard heating. A well-insulated house cuts demand even lower. The unit can run for 25 years without needing to be replaced. If all buildings had them there would be far less demand for electricity overall.
Geothermal energy is energy taken from the Earth's core, it comes from heat generated during the original formation of the planet and the radioactive decay of materials, and is not green in any way. Just because it doesn't cause CO2 emmissions some shallow thinkers imagine it's part of the solution to global heating, it isn't, it's part of the problem, and while fossil fuels are being phased out geothermal is expanding because simple non thinkers imagine it's green. Just repeating low carbon is a mantra to reassure those scared of the consequences of climate change. Dream on.
An idea that works on the same principles as Communism. That is to say that on paper it works, in the real world the poorest in society will pay the highest price. PS. If you are living in a place that despite 'global warming' is still cold then its not global warming.
