Cavity Wall Insulation for ASHP
To get the government grant for an ASHP: Your property must have a valid Energy Performance Certificate (EPC) with no outstanding recommendations for loft or cavity wall insulation. Our house does not have cavity wall insulation and I am planning to have it installed. What I am uncertain about is whether to extend the…

ASHP Legislation
Hi, is there any legislation regarding the installation of ASHPs that specify the distance from the front of the unit to the boundary fence? We have been told ours is too close to the fence and that it should be at least 1 metre from the boundary fence. Is this correct, and if so, what is the legislation and how do we find…

ASHP - Terraced house
So whilst you can't plonk one outside the house fairly easily, say you've got a cellar in said terraced house Could the ASHP go in the cellar instead? Would the COP also be slightly "better" in such a situation too given it isn't actually exposed to the outside temperature but rather the internal temperature of the house?

Gas smart meter removal
Presently investigating the possibility of a Heat Pump, one thing springs to mind, I presume someone would need to remove my gas smart meter, not sure if it can be taken out FOC or is there a charge for removing? Don't want to get lumbered with a standing charge if I decide to go down the route of getting a Heat pump…

Help, need advice for ashp
Hello we have built a new house (no choice, last one falling down) and it's airtight and highly insulated. We were supposed to put an ashp in but we have run out of money and don't get a grant. Also have heard a lot of horror stories about crazy electric bills. So plan is to plumb it for an ashp but put on for a few years…

ASHP for Water only + Electric Radiators (FTB Purchse)
Hello! FTB here and surveying options. There are quite a few new build (2023) 1 bed flats nearby that use ASHP - but only to heat the hot water (this done via a "vent brick?). I am aware that the property has EPC of B (and there is varying opinions on the accuracy of these). The EPC says the estimated costs are approx £800…

I need to turn mains water off for a bit, will it affect ASHP?
Hi I want to fix a dripping tap, so Ill need to turn the mains off. Will this affect the ASHP plumbing? All my heating (radiators etc) is controlled by the ASHP. I think its safe to turn off the water, but thought Id check first. Thanks

Concerned over ASHP noise for sensitive ears
I have reactive tinnitus and hyperacusis and a new 60 home housing estate is being built, nearest house will be approx 35 metres away from my house. All 60 houses will be built with air source heat pumps due to the new government rules. I am terrified I am going to have a low frequency hum cutting through my ears,…

Heat Pumps and "Microbore" pipes
Would like to pick the collective brains about Heat Pumps and a 25+ year old central heating system that uses 10mm "microbore" pipes. I have 250m of this piping and 19 steel radiators in my wet system along with a 300L HW tank. The system is in good condition, works perfectly and keeps my well insulated (as well insulated…

New home, solar and ASHP, or new boiler?
As title, moving in 5 weeks and the boiler needs replacing. Looking at Solar and battery, with an ASHP but will this do our hot water as well? Would you just replace the GCH, add solar, or solar + ASHP? This is a long term home so happy to invest for the long term. TIA

I've posted this before in the green and ethical forum but is worth mentioning as the scheme looks to have been extended again without a deadline: https://www.barclays.co.uk/mortgages/greener-home-reward/ £2000 for a heatpump for Barclays mortgage customers. Or lower amounts for solar or other green improvements. Other…

101 Intro to Heat Pumps & running costs - help required
Hi, Had a survey for a heat pump via Octopus last week and have just received the response. I'm scheduled to have a call with the sales advisor a little later. In anticipation I'm looking for a little help in trying to work out the likely running costs, so I've got a better idea if this is all worthwhile or not, so any…

Interesting heat pump installs and resource links
Perhaps after viewing some of these the myths of older, badly insulated houses and heat pumps can be put to bed, or at least give home owners a better idea of what they can do with terrace/bungalows etc that have low EPC ratings. I particularly like Glyns installs https://youtu.be/Hyv_vQEvHgo?si=QaCq2H6FoNmwE-V-…

Hitachi ASHP - Freezing
Moving to a new build with a Hitachi ASHP - RAS-3WHVRP1. Trying to understand the issue of freezing (if there is one). Can any explain the freezing issue with respect to this heat pump?

Old ASHP cycling - lack of modulation?
IAS a temp fix for our failed gas boiler I have added a second hand ashp into the rad circuit. Seems to work fine except that it cycles rather than modulating down. It has a rated output of 13kw and draws about 4kw. I know from our modulating boiler and smart meter that at current temps we would use about 3-4kw of heat…

ASHP service do you bother and if you do how much do you get charged?
So our Ecodan can with a service manual and for the last couple of years we have done the regular maintenance and kept an eye on performance and pressures etc. Before Christmas next doors had theirs serviced and the guy was there for four hours they passed on his number and yep at ours for four hours checking everything…

Multi split heat pump
We recently moved in to a 1930s semi. We have an old boiler with an immersion tank that is expensive to run, and rooms are often still quite cold. Local gas engineers have advised replacing it with an efficient combi boiler and said we’d also need new radiators as ours likely couldn’t cope with a pressurised system.…

Ecodan
Relatively new to this system as we just moved into a new build, seems our water is heated by immersion, as we have no mains gas supply, our ecodan has underfloor heating and 2 rads upstairs, all controlled by individual room controllers, but its the settings that are confusing, do you have it on flow/curve or room ? what…

Underfloor cooling with ASHP?
As part of a renovation, we're going to be installing UFH with an ASHP. We're also considering air conditioning for the bedrooms, but I'm wondering about using a reversable ASHP for cooling instead. I mentioned this to some of the ASHP people we've been getting quotes from, and their comments have basically been that it…
