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

LG units are good and affordable you'll need proffesional install.

You could buy a DIY unit that has Flexi pipe but I have no experience of them.

Hello all,

I'm currently debating whether to stay with my THTC meters at the moment or remove and just get a standard meter. I had storage heaters but removed them and put in an ASHP with air units in the house.

One local electrician has said i should keep the THTC but going by rates and comparing i think i should be able to save with changing to just the single standard meter.

Any one on here done this change?

Cheers.

Deffo switch to a standard meter if you don’t have night storage heaters any more.

If you are a competent DIY'er you can install your own, have just done so myself but as my current unit has R32 gas (inverter type) I had a qualified person come to flare the pipe ends and vent the system then check all was good.
The budget units (in fact most units) are pre-gassed & the above can be done yourself without the need for tech to turn up, but this is the UK so you need to check house insurance/regs etc so you cover yourself & on balance this was the main reason I had a tech myself (never had to worry about this in Spain though)
IMO it will work a treat in your conservatory & can be removed should you need to move it at any time.

What size unit did you install, and at roughly what cost please?

VFR

Mine is a Panasonic CS-FZ25UKE & cost around the £450/500 mark (did not pay that), tech to finish the install was £120.
I bought this unit with a deep discount otherwise I would have gone for a budget myself and many of these now come with a quick connector for easy install to the outside unit. (unlike the more expensive ones)

Unit is small enough to run from a regular 13amp outlet as its rated around the 2.5kw mark.
When I say budget these seem to be around the £350 mark in the UK but easily bought for around 200 in Spain so I am out of touch with UK prices that seem to be a good deal more (can be a lot more)


Anyway, if you want fast inexpensive heat aircon is the best route and of course nice in the summer.

Look into Lg Units: standard plus, deluxe or Artcool (mirrored finish) these systems are very reasonable.

There's also a floor console unit they do which is great in heating as it blows warm air out at your feet giving a more even heating area.

Hi everyone,
New to the ASHP world and looking for some advice.

My landlord has just installed a ASHP system after my oil fired system broke down in mid Dec. Last week it was working for the first time but only for 48 hours. Temp got to about 18c which was ok. Then I returned home on Friday and the entire system had shut down and appears to have no electrical supply, all trip switches were fine but the controls would not even turn on, now waiting for electrician to attend. I'm so sick of no heating and hot water since mid Dec. Could high winds of 50mph blowing directly on to the fan unit cause it to burn out or blow a fuse? I live right on the coast and there is often high winds and it get very cold, just a few weeks ago -12 during the night. The system is a Samsung 9kw system with hot water tank, feeding huge rads in a 1850's house with no insulation aside from 15 year old plastic double glazed windows.......... I understand I will have to run it constantly (if it ever works for long enough) and I'm concerned about the efficiency, whether I will ever be warm again and also the cost of it running constantly. Any advice would be much appreciated.

The fan won't be impacted by high winds, what could have happened is rain may have been blown into the casing somewhere where it might not have been screwed down properly and has shorted out one of the PCB's.

Thank you, glad to here the high winds will not cause problems but possible PCB doesn't sound like a quick fix.
