A listed building and heating system
I live about 46 meters from a 210 year old listed stone building My boiler busted and I’m having it replaced by Northern Ireland Housing Executive under their Affordable Warmth Scheme Normally it would just be a straight swap - oil for oil. However, the boiler been that close to the structure I wonder if the HE considers,…

Whether to disconnect gas supply following heat pump installation
We had a Vaillant Arotherm Plus 7kW heat pump fitted by British Gas a couple of weeks ago. They did a brilliant job and we're very happy with things, although we've only used it for hot water so far. We no longer have any gas appliances and I'm considering disconnecting from the gas supply in order to avoid the standing…

Calculating how many kWh/day electricity a heat pump will consume (worst case)
Hi all, apologies for asking this here as well as in the Green and Ethical section but it's buried away in a thread mainly about something else. I'm trying to work out what battery capacity I'll need to run an ASHP on off peak electricity on a cold winter day. At the moment I have gas central heating. I have a 15 kWh…

What's your monthly SCOP
As there are a few of us with ASHPs installed, I thought I'd start a thread to compare monthly SCOPs so we can see how we are performing.I had my 12kW Samsung ASHP installed in June. It's been heating DHW over the summer and we are just now starting to get a feel for heating. It's an oversized unit, so we won't be able to…

People Saying Heat Pumps are Rubbish - Are They?
I think most of the people I've spoken to have always read "something" about heat pumps being a bit rubbish for heating homes and having showers. But I rarely see this from people who have them installed, where the general view seems to be fairly positive. I understand it's a bit of a learning curve coming from a gas…

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

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…

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…
