Midea Heat Pump expensive to run
Hi all I've just bought a house with a Midea heat pump fitted by the previous owner. She left me a very vague handover on how it works but admitted herself that she never really felt like she understood it. I'll add at this point that I am patiently waiting for the engineer from AirSourceUK who installed it to visit and…

Air to air heat pump?
Hello everyone. I’m in the process of renovating a 1950s 3 bed semi, and my priorities are insulation and heating. The current heating system is old storage heaters, and immersion for hot water. I’ve been researching different heating systems for a while now, and would appreciate any input to help in my decision. I’ve…

Warm Homes Plan - effects on those in Scotland?
Just wondering about the UK government’s warm homes plan and how this will affect those interested in solar/batteries/heat pumps in Scotland? Anyone have any insights on this? The Scottish gov seems to already offer similar grants anyway (or am I missing something?). Thanks

ASHP Quotes
I have an oil boiler and am off the gas grid. I’ve been getting quotes for supply and fit of a 14 kW ASHP and 250 L cylinder. The engineers that visited confirmed that my radiators and pipework are fine as is. I tried local MCS-listed installers and also big energy companies. All quotes came in around £15 k, minus the…

Problems with ASHP supplied on Eco 4 grant
In October 24 we had a whole system installed under an Eco 4 grant ( due to husbands ill health) It didn’t work properly for 12 months ( by their own admission) We had regular return visits from plumbers, electricians & surveyors. It took until October 25 for it to work as designed. I can see from our electric bill that…

Is Valliant extended warranty worth it?
https://www.vaillant.co.uk/service/heat-pump-cover-care-packages/ I noticed the extended warranty includes annual service. Or is it better to just buy a third party service plan which is about £220 a year.

DIY & Ecodan Heating System
I've just moved into a house with an Ecodan Heating System, I know nothing about ASHP so this is quite a step learning curve. It was installed by GreenGen in 2021 and I've booked a service and hope they can explain a bit to me then. Unfortunately the service is not until March and I wanted to remove a handbasin and…

Under Floor Heating with my GSHP
Hi all, Happy New Year. I have a problem with my underfloor heating, unfortunately I suspect it could be a messy fix. When it was installed in 2009/10, one of the plumbers kink'd the pipe to one of my upstairs bathrooms. The pipe runs in spreader plates fixed between joists with insulation fixed below. Instead of cutting…

My ASHP Journey in Bonnie Scotland.
We have our new ASHP - just three weeks now and I want to get the best from it. As it was part funded by a renewables grant we also had a phenomenal amount of additional insulation put in the attic. We have 2 zones - upstairs and downstairs. I have so far left the settings as put by the installer. 20 downstairs 18…

Frozen Heat Pump
Our first winter with a heat pump and it is very cold here (around minus 10 last night). The back of the pump has frozen over: One side has rather a thick covering of ice. Is this normal? Online reading suggests it should run a defrost and low refrigerant could be an issue? It's a 12kw 6th Gen Samsung. Thank you in advance…

Powerflush with GSHP
We had a slow leak on our central heating for a while, which suddenly became a fast leak (about 1 bar every 10 hours). Can't find evidence of a leak anywhere. I called a leak detection company. They advised a power flush because leak sealant has previously been added to the system, which can interfere with leak detection…

Extra heat sources impact on HP
I have an A2A HP and a log burner in my lounge. I am having a wet HP system fitted, what will be the impact of using the first two on the third? As an example, I light the log burner at night and the room temp (door closed) might hit high twenty c’s, how will that impact on the rest of the house?

I know absolutely nothing about how this sort of system works and how it could compare in cost to what we have now. Currently we have multi fuel heating, with all of our…

Complex Leak in system after Heat Pump Install
Hi, I thought I would look here to get some information, as I seem to be going round in circles with Octopus. Last December I had a Daikin heat pump installed through Octopus, it was a painful process to get that far but I was excited when it went in. Since then though it's really not been smooth sailing. I noticed almost…
