Heat Pumps: anyone have one/thought about it?

We went for Air to Air heat pumps, because they are slightly more efficient, give better per room control, quicker response, and cooling in summer.

2x9kW Daikin multisplits, one on each side of the house, each running 4 indoor units. Very happy with them and not used gas since getting them installed!

We actually have both now, a Mitsubishi 8kW split air to air installed in 2022 which services the three main rooms (living room, kitchen and main bedroom) and the more recent 6kW Daikin air-to-water installed by Octopus in April.

The Mitsubishi is mainly for air conditioning but we have used to it to bring rooms up on particularly cold days. It is rated at a COP of 4.7 and will sit as low as 480w when heating and 350w when cooling quite happily.

Our gas meter goes on Monday so no more standing charge!

Octopus were fine doing the BUS grant without touching the split?

I would like an A2W for water heating and possible ufh.

As long as it's totally separate (electrically and isn't too close) they don't seem bothered. They initially made comments about planning permission being required, but the council planning department said there was no need for it and the latest reg change seems to do away with all of that anyway.

The BUS grant itself wont be an issue as long as you're replacing a gas or oil boiler.
 
The issue with the BUS grant is it talks about the new ASHP being the "sole source of heating", I guess you can make the argument that the A2A is for cooling.

I want to do UFH everywhere and rip out radiators, but only if I can get an A2W with the BUS grant. Otherwise I'll keep heating via A2A.

I think I would technically need planning still as it would be a 3rd unit :D

I risked it with the existing two, knowing they didn't comply at the time but that if I got a rectification notice I'd have 6 months to rectify and by that time the new rules would be in place and I wouldn't need planning anymore.

I wondered that, question answered if you click the link in his post. If you read the comments, they are all complaining how expensive the electric is, seems it's only just reached out current rates, basically they've had it cheap compared to the UK.

It appears prices were held artificially low for years by regulators, the electric supply company also had a fixed price contract with EDF which appears to have supplied electricity at a loss after the big prices rises, and that's come to an end

Yes sorry, should have mentioned I'm in Guernsey, CI. We're in a fortunate enough position to not be impacted greatly by the price hikes.

Most of our electricity is imported from France, and the the pricing hikes are there primarily to deal with lacking infrastructure for modern demands as I understand it - more and more households are becoming fully electric, and the network simply can't cope!

I know people who have applications declined for heat pump installations and car chargers due to the risk of overloading the network.

I'm unsure how standing charges work within mainland England, but that's a huge portion of our bill and not actual unit usage.

Standing charges here are 47.6p/ day. Some are higher some are lower depending on where you live, London is cheaper, Scotland is more expensive.

The standing charge makes up about 20% of my import costs but my solar exports more than pay for my entire bill.

Solar is the way to go for home owners.
 
Ours currently works out at ~95p per day, and will raise to over £1 a day when the new tariffs hit (based on having two meters, one for residential electricity and one for the heat pump).

Over £100 per quarter, justified by trying to extract more money out of people who have solar yet still rely on the islands infrastructure with low unit consumption from the grid.

Most people here have a separate gas standing charge as well though rather then two for electric. The combined charge most people pay under the price cap is currently about 86p a day and will be falling about 4p in July.
 
A separate meter, due to tariff difference - same main cable feeding it! It's a 3 phase cable however, and 1 phase is used for the heat pump and house. The remaining two are currently not used, but we do have a 3 phase heatpump to be installed in the distant future (or sold, given we may never get round to installing it!)
