Re: Cavity wall recommendations near Edinburgh

No one?

How about has anyone had a bad experience? Ie any contractors to avoid?

Cavity wall recommendations near Edinburgh

Hp installation has made it clear that our single -storey 80s extension has no cavity wall insulation. Before I get lost on Google can anyone recommend either a local contractor or a national contractor who are nice and straightforward? Also, which is the right / wrong material for it? I remember da...

Re: Samsung HP any good?

I like the simplicity of being able to plumb HP into existing circuits then upgrade rads later if need be. Sounds good to me too... Yep, this is what I was worried about but this forum and the plumber (who was a member in the other place) gave me the confidence to go for it. So far it’s working gre...

Re: Samsung HP any good?

We’re in East Lothian Gareth. Pm me if you fancy a coffee in Edinburgh to discuss as I’m in two or three days most weeks.

Kerosene (Heating Oil) in a tractor?

Our oil boiler died soon after we'd filled the tank. I'm very pleased to say we've now replaced it with a HP. I now have over 1000 litres of fuel oil sitting in a tank, though. We could theoretically sell it to someone who would take it in ibcs but i somehow doubt we'd get much for it that way. A fe...

Re: Samsung HP any good?

Hi folks. I thought I'd post on here in case anyone looks it up later. 14 kW Samsung (16kW for cooling I think) ASHP was installed 5-6 weeks ago now and has been running well. Better than expected, tbh, but that's because there seem to be a lot of anti-HP scare stories and press out there these days...

Re: Battery or thermal storage for HP timeshifting

Thanks CPaul. Yep, I think you've confirmed my feeling that insulating and draftproofing the hosue would be the best bet as it would enable the thermal mass of the building to be used. And to get on with replacing radiators with underfloor. Though we're in an exposed stone-walled farmhouse, so I don...

Re: Battery or thermal storage for HP timeshifting

Now, assuming your non peak times are 7 hours then you will need 127000/2.7 (an average cop) 47kWh input or 6.7kW from the grid to your HP to charge the tank let alone service your heating. Single phase wouldn't be able to recharge in the time required. Hi Andy. I wouldn't be trying to load ALL the...

Re: Battery or thermal storage for HP timeshifting

And thanks HML. Yep, it's definitely beginning to feel like just HP producing elatively low temp heat and thermal store doesn't make a lot of sense. Certainly with domestic payments for providing grid flexibility as they are - just simple time-of-day tariffs. A high temp heat input on top of the HP ...

Re: Battery or thermal storage for HP timeshifting

A very quick google shows 5,000 litre thermal stores at £3-4k. That's not installed though. I'm pretty sure we'd be talking £5-6k once installed by a friendly plumber. Which is roughly price of an off-the-shelf 10kWh battery, right?
