I'll be running the heat pump only when it's on the cheaper rate, which is 7.5p kw/h, so a slight reduction in COP isn't a huge biggie. Just wondering if the Mitsubishi is worth the extra 2.5k or not, or if the Samsung will be easier to control via home assistant.

Hi, I've had numerous quotes for heat pumps. The majority went for a Mitsubishi Ecodan 6kw PUZ-WM60VAA(-BS) heat pump with a 200litre water cylinder for about £4,000 (After the government incentive). But we've just had a quote for a Samsung AE080RXYDEG/EU 8kw heat pump with a 210-liter water cylinder for around £1,500. Just looking for any input to see why I shouldn't go for the cheaper quote for the Samsung? Or if there's a reason most companies choose to go for the Mitsubishi. One must, is that it must be able to integrate with Home Assistant. I know Mitsubishi does with the MELCloud integration, but unsure about Samsung. I want to only have the heating on & heating the water tank when the car is on charge and activated my cheaper Octopus Intelligent tariff. I live in the UK, we have a small semi-detatched 3 bedroom new build house from 2019. I believe it's around 95 meters squared in total, and it doesn't need much heat to keep the house warm on the current gas boiler as it's well insulated. Thanks.

Okay, I see it was a bad idea to post here. Just being told that it doesn't make sense. I just wanted to cut off my gas and go completely electric to put pressure off gas and go towards renewables. As far as I see it, the gas standing charge is paying for the upfront for the heat pump, and I'll be saving money on the gas I use on my cheap electric tariff.

@SteamyTea @Gary68 @Roger440 We're currently using about 1.5m^3 of gas a day. Our Bill shows that we use around 1800 kWh yearly. It does come with a wifi module for MELCloud. We haven't had a proper heat loss survey, that would be done once we place a deposit and decide to go ahead with it The main reasons we're doing it is to go fully electric and remove our need for gas, and aim to save a few £'s from running in the cheap electricity rate. We got quotes from 4 companies, they all suggested the same Mitsubishi 6kwh heat pump unit.

I've recently got quotes for heat pumps, and found one at £4,000 for a Mitsubishi 5/6kw Heat pump, and a 200L cylinder in the loft with 7 radiator upgrades after the gov grant. I'll be adding this onto my remortgage so it's costing a couple of quid a month for the upfront cost. I live in a 2019, 3 bedroomed, small new build so it's very efficient, usually only need the gas combi boiler heating on for 2 hours a day max when it's currently about -1 degrees c. If i get onto the heat pump, I can cap the gas off and stop paying the standing charges for it. I'm currently on Octopus Intelligent with my EV, and I get cheap rates of 7.5p between 23:30 and 05:30, and can get more hours of this within the day when 'charging' my car. Outside of this, it's 30p kw/h. On a usual day, I can get 7.5p kw/h between ; 09:30 - 12:00, 14:00 - 16:00, 20:30 - 22:00, 23:30 - 05:30. My question is, I know heat pumps should be left on 24/7 at a set temperature. However, I could run the heat pump 4x cheaper than the normal electricity rate if I keep within those set times to reduce to 7.5p kw/h. If I set the schedule on the heat pump heating to only run between the above hours, as well as the hot water heating within those times, will it be enough to heat the house? We're comfortable with about 18 degrees, so don't need the house super hot.
