Extending a property with an ASHP and underfloor heating
Hoping for some advice from those more knowledgeable, please Have viewed a property we really like this morning which was built about 3 years ago with an ASHP and underfloor heating, neither of which I know anything about. We would need to build on, either a ‘proper’ extension and/or a conservatory/sun room (with a proper…

ASHP heating problem
I have a Samsung ashp heating pump, no air in the rads to bleed, no error on the screen, although there is one in the logs. The system shows as both heating and water on, but no matter what I do, I cannot get any heating

A2A Heat Pump / Air Con
As with the 29/5/2025 changes I understand that it's possible to install air con / A2A heat pump without planning permission? We don't have radiators / gas at the property and air to water heat pump costs even after grant were just too high, hence I was thinking of getting A2A mostly for heating and casual 5-7 days a year…

Anyone replaced central heating with air to air in bungalow?
As per title wondering if this is a good idea vs keeping central heating and heating a heat pump. Im thinking going immersion for hot water but the idea of being able to cool and heat rooms and dehumidify etc is quite appealing. That with cheaper cost cos bungalow with suspended timber floor means I don’t have to lift…

Ducted A2A heat pump
Hi all, does anyone have experience of ducted air to air heat pumps? I used to have a heat recovery ventilation system. It didn't work very well so I removed it, but the duct routes are still there which makes me wonder if this would be a good route to go down.

180L Cylinder
Just have British Gas come out for survey today. My space can only fit slim cylinder but BG only have 180L the biggest. He tried to convince me this should be enough for my 133m2 3 bed bungalow and 5 of us (3 young kids, but they will grow...). I think this is really marginal although we only have 2 bathrooms and it is…

BUS grant and NRPF
I was wondering whether the Boiler Upgrade scheme (BUS)
comes under the category of No Recourse to Public Funds (NRPF) Or is this
something one can make use of without violating the NRPF especially
for those who are on Visa?.

Battery with heat pump but no solar - your thoughts
Hi all,We're just starting our retrofit journey and have had a home energy assessment which gives rough guide costs for each of the project elements. Obviously we are going for a fabric first approach, adding more insulation above the ceilings, reducing drafts where possible & replacing our ancient double glazing (at a…

Water tank placement
Hello My gas boiler is near end of life and I am looking at my options. I live in a 3 story 4 bed detached house with fairly new radiators that are about 2x the BTU that are needed in each room and the heating uses 15mm plastic pipes embedded in the studded walls. I have 3 bathrooms. I am looking into if a heat pump will…

Radiator Fans rather than upgraded Radiators with ASHP
SO we all know that with more efficient low flow temps for an ASHP it is likely that rads may be undersized. The correct option is of course to fit larger rads but I was wondering if Radiator Fans could be used instead as a short term solution? With rads it is easy to find the heat output at different flow rate but I can't…

3 way valves
Hi, I have an IVT HT+ E7. Last September (2024) I noticed the flow to the UFH was getting hot when the Heatpump was heating the DHW. I opened her up and saw the 'disk' on the 3 way valve just turning slowly. It wasn't stopping at one particular outlet, just kept turning. Not sure if this was a micro-switch problem inside…

Heat pump replacement using BUS scheme??
Hello. We bought a house in October. House built in 2009 already with heat pump. Long story short - it keeps braking and cannot fix it. Has few quotes to replace system. One of heating engineers adviced that it's possible to use BUS grant to replace it - but what he meant was to get few electric heaters get new EPC that…

Quote for ASHP
Just had a survey done for an ASHP 13kw for a property with approximately 120 square meters. 9 new radiators, full installation. I’ve not been able to find many other quotes that other people have had but I’m pretty sure this one is very steep! £20k before any grants. With all the grants we’d need to pay £11k. Doing some…

Please help with this heat pump dilemma
I’m looking for advice on a heat pump install and facing a few issues. The biggest problem is space: my current airing cupboard (which holds a cylinder linked to a back boiler system) has a depth of just 480 mm. E.ON told me the Ideal system they offer needs at least 650 mm, and the Vaillant AroTHERM won’t fit either. Is…

Octopus HP survey - what shuld I ask?
I have booked an Octopus survey for HP for a 4 Bed Detached in May. What should I ask - can they give me some sort of idea of running costs. I am not bothered about a return - I am in my 70's. I do care about cutting carbon. I am 1 in a 4 bed house but hoping that HP would make it more attractive to sell. Not against…
