Air source heat pump costing loads in electricity.

I dont have a Samsung (mines a Daikin), so I can't comment on how it operates or how your system configured or controlled.

However as Andy says, you need to try and leave the unit controls to control the unit and just use the room stat and TRVs to adjust for the temperatures that you require in each room. have a shufti here https://www.freedomhp.co.uk/wp-content/uploads/downloads/Installation%20Manual%202019%20for%20email%2019-07-19.pdf and read page 7

Also because heatpump systems are much slower to respond, you should only make small adjustments to one thing at a time and give it a couple of days to stabilise - keep tweaking just means that you don't know what is going on - if necessary write down the settings, together with meter readings and what the weather is doing so you can correlate what is happening

It probably took me a couple of months before I'd got my system set up properly and by shutting it down to a low level during the coldest part of the year we ended up doubling our electricity consumption whilst it struggled to reheat the house using the boost heater. We just let it get on with it nowadays and if it's everso cold it runs all night at a low level rather than trying to get it to go flat out to reheat the place

If the heatpump has weather compensation enabled then it will adjust the flow temperature depending on the external temperature and so will turn the heat pump down when it's warmer and up a bit when it gets colder so mucking about with it will actually reduce the efficiency and cost you more. What temperature have you got your hot water set to, we get away with 45 degrees with a boost to 60 once a week.

Looks like we have both settled out at similar numbers. Mine is set to 44C and I don't use a boost, I let the solar immersun boost the tank up to 60+ whenever there is enough sun to do so - today was one of those days. I've not had to intervene yet, the sun shines enough at least once a week / 10 days even in the gloomiest of weathers I find.

Hi, I'm new to this forum but hoping for some info, - trying to buy a property but so far put off by the heating system, it has a Dream 22Kw Air Source Heat Pump, the property is 3850 sq.ft. - Is the pump vs floor space about right? Any ideas on running costs, it also has an immersion heater for hot water top-up. The current owner is not there all the time so cannot give me any accurate figures except about £100-150 per month which reading here I don't believe. Any help would be really  appreciated, many thanks, Jeffrey

Hi All
I am looking for some advice, if you can help.
My mother currently has Economy 7 storage heating in her home (she has under floor heating in the kitchen), which is both expensive and inefficient in heating her home and we are looking at an alternative heating system. There is no gas supply on the estate, so a boiler is completely out of the question.
Her home is a very small 2 bedroom property, with just the kitchen and lounge on the ground floor, with one double bedroom, one single bedroom and a bathroom upstairs.
The house is a terraced 'cluster house' with properties to the left, right and behind hers. She only has a front door with a small garden (no back garden).
We are looking at an electric heat pump for heating her home and I was wondering what the pros and cons of this are? Would this system be sufficient in heating her home in the winter months (the loft is well insulated)?
Any advice or help would be greatly appreciated.
