I live in a village without mains gas and inherited an external oil boiler when we bought our bungalow in 2018. This is a timber-framed property built in 1980 and the central heating pipes that fed the radiators had been buried just below the surface of the concrete floors without any protection against corrosion.…

A little story… ...I decided to get a heat pump installed by Octopus. The installation went smoothly last July and I had all new radiators as well. Very happy. Come winter and the heat pump was working constantly and the house just never was warm enough. Several engineers ( I think 6) sent out to investigate and endless…

Outdoor "air conditioning". I was doing some fairly heavy work in the garden, and was a bit of a sweaty mess, when I noticed the ASHP had fired up to do the hot water. Stood in front of the fan for a few minutes and was restored to cool as a cucumber status. Have you found any unexpected features in your installation?

I have put together with information on reverse cycle air conditioning (heat pumps), where people can ask questions, chat about heat pumps, discuss experiences, installs, electricity usage & anything else heat pumps related. There's a lot of info here to take in, please do read it all as this may just help. However, if you…

I thought this was cheering: https://www.theguardian.com/environment/2026/sep/17/milk-source-heat-pump-barbers-cheesemakers I like their cheese too, but don't think they do an unpasteurised, which is a shame..

I thought I'd join in all the air-to-air excitement 😄 but I'm not ready to have F-Gas folk around for a permanent installation (my house is full of stuff my kids have brought back from university and it looks like a candidate for one of those "extreme hoarders" TV shows). Instead, I have bought a 12k BTU (3.5kW) portable…

Just had a survey and quote and just for the bedroom at this stage a single unit quoted £1225 all in. Hopefully fitted before 16th June before the installer goes on holiday and before the next ramp up of heat. Daikin unit so the budget end of the scale (5 year warranty) but realistically they must all be much of a muchness…

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-…

As ASHP become more mainstream as heating they become a part of the main energy board. ASHP are rarely left by installers at the most efficient settings and often installers will leave them turned up to max to mimic gas central heating so they don't get called back for radiators that don't scold your hand when touched.…

https://www.daikin.co.uk/en_gb/residential/products-and-advice/product-categories/air-conditioners/multi-plus-split.html I didn't think an A2A system that heated a hot water cylinder existed yet. I have asked for a survey and quote and will go the Multi or Multi+ Split route, depending on installation requirements . Has…

New, improved grant to get rid of oil or LPG heating: https://www.gov.uk/government/news/decisive-action-to-break-influence-of-gas-on-electricity-prices

Looking for some advice please on getting best out of green energy tech. Have recently installed Vaillant aroTherm 7kw (new larger rads). 4kw solar panels and 5.12kw battery. I am not seeing any reduction in costs over the 15 yr/o electric boiler it replaced. House is 25 y/o 2-bed detached bungalow in central Scotland with…

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…

I can't see any mention of heat pumps freezing over at low temperatures. Ours freezes over at anything lower than 3C. The defrost system activates but the effect is pretty feeble and all it seems to do is consume more electricity without giving us any more heat. Leaving the thing on set to 18C inside temperature with sub…

https://www.current-news.co.uk/octopus-energy-announces-the-launch-of-its-cosy-6-heat-pump/ Fascinating development - wonder how it will stack up against the Arotherm+?

https://octopus.energy/smart/cosy-octopus Whether it makes financial sense is for heat pump owners to judge. PS: it is compatible with Agile Outgoing.

https://www.gov.uk/government/statistics/heat-pump-deployment-statistics-june-2026/heat-pump-deployment-statistics-june-2026-summary Any thoughts on what has caused the decline in adoption?

So we have had one of these units for just over 5 years. It just failed (no power up) so if anyone would like to see the inside of one of them here you go whilst hubby strips it down and replaces the PCB and Motherboard. The PCB and Motherboard are all click connectors so the hope is it's an easy fix(famous last words) And…

We're starting the process of looking at the options for getting rid of the stinky oil boiler and stupidly small oil tank, and talking to ASHP installers. As we're planning on getting rid of the boiler, we've recently been running it as low as possible, and working on getting it delivering continuous low(ish) heat rather…

I have a Vaillant aroTherm Plus 5kW heat pump and a SensoComfort 720f thermostatic controller. The SensoComfort has a control called a heat curve which determines my system's flow temperature for any given outside temperature. But there is also a control to set the desired ambient temperature. What I don't understand is…
