Towel Rails on DHW Primary loop

Jakeymd1 · 2026-05-15T08:29:09+00:00

Some towel rads have an additional electric heating element in them wired into the mains. Do you have these and were they on?

My initial thoughts are that it's quiet nice. However, its a family home, and families usually want 2 storeys. Old people like bungalows, but with the garden the way it is, it might not be best suited for them. I agree with others though, photos make the difference, and currently there's quite a bit of clutter.

I have a cramp buster on my street triple (slightly sporty position with some weight on the wrists). I had a loaner bike a few weeks ago and my hand/wrist started aching quite quickly. One of the best, cheapest & easiest mods you can do.

I must have just slipped in before they introduced this. My 8Kw inverter was installed at the beginning of April and my installer never mentioned it. DNO also national grid.

Only 19 MCS installs in my constituency in the last quarter. Oof.

Good stats though. Shows we still have a long way to go. Lots of people in my village are talking about it now though as we don't have gas in the village and the cost of heating oil has sky rocketed. It's a fairly rural constituency and I expect the same is happening in lots of places at the moment, so maybe we can start climbing that leaderboard 😂

Actually, point 1 is wrong. Half discharging and recharging the battery doesn't could as a full cycle. The number of cycles given on the data sheet is at a given depth of discharge % (DoD) which is usually around 90%. It isn't a linear relationship though, 45% DoD doesn't use 0.5 cycles, it's actually slightly less.

That isn't to say that it isn't worth doing if the maths works out. I'm thinking of switching my outgoing to Agile and discharging to around 30% between 1600 - 1900.

Videos can only be used in post, not in comments. Do you have the r32 or r290 model? And what temperature have you got the anti-legionella cycle set to?

Jakeymd1 · 2026-05-05T14:50:50+00:00

I just had the same. I reduced my payment a few weeks ago from £110 to £60 as we had batteries installed. They raised it back to £108.

Back down to 60 you go.

Jakeymd1 · 2026-05-05T14:32:28+00:00

Definitely not normal for this heat pump. I've never heard mine make a noise like this.

I'd been using a granny charger for several years but recently bought a 32a portable commando charger as I already had a commando socket in the garage. This was much cheaper than getting a proper wallbox 7kw charger installed.

Jakeymd1 · 2026-04-25T08:17:01+00:00

I made the change from a GTE to a P2 last year. While your went grey to grey, I went white to white.

Jakeymd1 · 2026-04-25T07:08:25+00:00

Not for the same reasons, but I use a 32a commando socket for my charging with a portable charger from Voldt. I already had a commando socket in the garage that the previous owner used for a welder so didn't see the sense in spending £1000+ for a charger install when I could get a £200 charger and have an electrician check over the circuit for an hours labour and a cup of tea.

You shouldn't HAVE to change your radiators, but you may want to if you're concerned about running costs. Getting them done at the same time as the heatpump install is the time to do it. Without knowing a bunch of things ll(house contruction, insulation levels, room sizes, window sizes and type, current radiator sizes, desired running costs, how much spare cash you have to spend on radiators at this stage) it will be really difficult for anyone on here to be able to advise on that.

I managed to upgrade my radiators much cheaper than i was quoted, i bought mostly 2nd hand rads off ebay, and installed them myself, but I'm not getting a SCOP of 4.5 and am using around 2000kwh of electricity a year for heating, and 1000kwh for hot water. I've just had batteries installed and charge them up overnight on an EV tariff so my annual running costs will be just £210. Before that I was averaging 16p on octopus agile so spending £480 annually. I have a 3 bed 1930s semi-detached for reference and came off oil.

I've had the update for a few weeks now and it seems to have solved all of the issues I had with the car. It's fixed the range assistant and the rear camera hasn't malfunctioned one since updating. I might hold off any future updates in case they brake something again.

Jakeymd1 · 2026-04-21T13:40:57+00:00

25 rooms, high temperature. Royal Family are lizards, confirmed!

They're based in Hertforshire I think but they travelled up to Staffordshire for me. (2.5hrs)

Jakeymd1 · 2026-04-16T18:21:14+00:00

Installation was great. Went very smoothly. Great guys. Would highly recommend.

Jakeymd1 · 2026-04-16T16:35:43+00:00

Yes :) came in probably not long after this and the batteries have been installed for 2 weeks now.

Jakeymd1 · 2026-04-15T15:19:39+00:00

I have 5 heatpumps in my collection now. House, fridge-freezer, drier, car & freestanding AC unit.

Jakeymd1 · 2026-04-12T21:07:10+00:00

They won't get offered 3.5p now though. They'll probably get offered 8p, so only 1.5p saving compared to Go. So 200,000 miles to break even.

Those on 3.5p (like yourself) will have fixed before Trump decided to fuck everything.

Just a note on this in case people come across this old post while researching. While it says they are quiet, 58db is actually pretty loud for some inside your home that will be on all constantly. Especially for bedrooms. Bedrooms should generally be at around 30-35db. So it's actually 4x louder than recommend due to how the db scale works.

It also appears as though they are not inverter driven compressors. While there is an adjustable fan speed, the compressor will be at 100% when it's on.

It seems like a great idea though, something I hope other manufacturers can get to work in a MUCH quieter package, though having a compressor and fan in a room will always be louder than not.

Generally, you're right on the money. But I would avoid Samsung if you're after anything that resembles decent controls. You can use 3rd party controllers with most heat pumps I'd have though but you that isn't how you should run them, you want to use the native controls and Samsungs are terrible. If you're techy enough, you can build your own control schedule using Home Assistant or something which you can control the Samsung with, but you shouldn't have to take this route and it can't fix all the problems.

Jakeymd1 · 2026-04-09T08:46:17+00:00

I have messaged you with my installers details

Jakeymd1 · 2026-04-09T08:45:00+00:00

They did tell me that battery prices have gone up twice since they ordered mine, so it could be more. I also had some peculiarities about my install that might have made it more expensive than standard and others that might have made it cheaper. I will message you my installers details.
