UPDATED: Air Source Heat Pumps/Air Con - Full Info & Guide, is it cheaper to run than mains gas?

Unusual terminology! What is the "power receiver component"?

I agree with comments about fantastic service, but some huge expense being incurred here. The company may well need to increase prices to recover from this situation. Maybe Albyota can keep us updated.

Even if the costs are £50mil or more.....to a global company such as Mitsubishi, I would have thought it is small change to them, considering British Gas have made £585mil profit in 6 months.
I don't think this will damage their reputation....they will probably gain from it.
I would say that their prices would reduce somewhat for a short while.

I think it should say:

An investigation has found that the accumulator part on the W85 unit failed under pressure due to a manufacturing fault.
The part is designed to control the level of liquid refrigerant, used in the heating process, in the system.

Re: supporting words with regards your BWarm 9000i of last September. Was your winter experience good? If not can you let me know what issues you had.

Odd how the units made in Scotland are fine, yet the other units are all to be replaced. Maybe that’s just me yearning for the return of the manufacturing industry.

The majority of the systems to be replaced were assembled in other parts of the world, Japan, Malaysia, Europe. They have been assembling the W85 VHA2 in Livingstone for a good few months now, these systems use a different component to the one that failed, Mitsi are producing around 3,000 units a year in Scotland, rumour has it, the 140's and 50's to follow on next year, Agree with you about the manufacturing industry, we used to be good at manufacturing in this country, a combination of, we just got too expensive and other countries can do it a lot cheaper, I think.

Hi, Been looking into ways to heat my new home. Currently no heating and looking at all the options. TBH never really considered this Heat Pumps until I read this and it has interested me. Are they expensive to install compared to OCH. Anyone give me a rough idea of installation for a 'dry' system for a 4 bedroomed house

Hi Sparkie, an Ashp with DHW Cylinder and 9 or 10 rads fully fitted would cost in the region of £8.5k to 9.5K. if the rads and pipe work is installed by yourself then the heat pump and cylinder fitted would be about £6k to 6.5K

Hi,

I realise that this is my first post so my credability might not be the best but anyway. I've reacently bought a smallish (50sqm) quirky flat that is more like a semi-detached bungalow. Insulation is OK, not good but could have been a lot worse. Heating is solely electrical with no gas in the flat and storage heaters are installed. Now to my point, I'm from Sweden and used to very cold weathers but nicely heated houses. The 'biggest' thing in heating for the last 10 years in Sweden has been air-to-air heat pumps and they are extremely common (think more like no oil or gas is used in Sweden, all new installations are pretty much heat pumps). I notice 2 main differences between the forums in Sweden (which are vary large with thousands of recent posts) and the discussions here. First and foremost PRICE.

Sweden is by no means a cheap country, pretty much everything is more expensive than in the UK. But, an installed Mitsubishi Electric heat pump with one internal unit is never (OK, maybe in very special circumstances) more than £2,000. Here people are talking about £4-5,000+. why is that.

Secondly, people here seem to complain that the unit is not efficient or working when it's cold, hmmm Sweden -20 degrees and my parents 170 sqm detached two story house is heated by a 5kw Mitsubishi unit with ONE internal unit on the lower ground in the stairwell, inside temperature in any room (internal doors open of course) never falls below 20 degrees. How can it differ so much in efficiency? OK, I know that we have 'space age' triple glazing as standard and everything is insulated but I've seen people installing 4 pumps with a internal unit in pretty much every room here... This is not how we use it in colder climates. And also, there seems to be a raliability issue as people are suggesting having a 'back-up' system. Why? I just say.

And after my rant, here is my question. If a buy a unit in Sweden instead (~£1,500) for a Mitsubishi and bring it here, would it be possible to find an installer for it? I'm in Greater London.

I would greatly appreciate any input/comments!

Thanks very much. And a ground sourced one ? Roughly speaking - more or less ? I will be doing as much of the labouring work as possible and probably even installing the underfloor heating myself.

Was thinking of having UF (I have to replace the floor on the ground floor anyway) on the groundfloor and rads upstairs. Is this possible ?

Given the price of gas and oil now I was even thinking that I would not bother with rads upstairs and just go with storage heaters.

Woodburner to heat the water - we're having one anyway so I thought that it would make use of the extra heat. Hopefully that mixture of systems will ensure that I can walk home into a (fairly) warm house after work, provide extra heating when the woodburner (I will get my wood for free) is on, top up the water temp in the summer (when there is no woodburner) with electric.By my reconing this would would out cheaper initially and give me some degree of control in terms of heating. All without oil or gas and the cost of installing all of this (Boiler, oil tank etc)

Any thoughts anyone ?
