Having emailed 3 companies in my area they now all confirm in Scotland the recommendation is an ASHP backed by a hydrogen ready gas boiler to boost the temperature. I can only go by the advice and recommendations of the companies fitting the systems, I have limited knowledge but my brother who designs AC and Heat Pumps has that exact set up in his house.
I will look into the Scandinavian model as we are clearly being wrongly advised in the UK
This may be a factor of the insulation standards of the average house in the area. Heat pumps require a high standard of insulation otherwise heat loss would cancel out a fair degree of the heating efficiency. You'd generally find insulation standards in Nordic regions to be of a very high standard for obvious reasons.

The extent to which this is specific to heat pumps is overstated - low insulation is a problem however you heat your house. As I say, in the electrification of heat programme they found 15% of houses needed extra insulation (mostly just loft) before installing a heat pump.

Yes British houses are generally badly insulated - getting loft insulation up to the minimum 270mm (10.6") of modern building regs is A Good Thing To Do however you heat your house, ditto double glazing any windows that aren't.

Heat loss through walls and floors is also a major factor. And relatively much more expensive to fix.

Sure - but in general you don't need to fix it before installing a heat pump, based on the EoH project we're talking 1 house in 50, something like that. (I forget the exact number but it was hardly any).

The real problem with heat pumps is that they need a bit of skill to install properly, and that doesn't always happen - they're less forgiving of bodging than a gas boiler. It's notable that heatpumpmonitor.org lists the training of the installer, and the ones with efficiency >4 have almost all trained with two particular outfits.

Anyway, this is all getting a bit OT....
 
We had a Worcester 4000 greenstar 30kw boiler fitted last week which is hydrogen ready, it is very smart, 30kw will run about 18 rads we have 6, most homes in the uk only need 13kw it will also modulate down to 3kw which saves on gas also i have altered the range they come preset at 86% you can go in the service menu and turn it down mine is now set at 60% which also saves gas usage i also altered the flow rate which was set at 75c to 65c, well happy with it
 
Just a bit!

Well to bring it sorted of back on topic, this weekends weather warning doesn't faze me, as we can always gather around our EV - that will inevitably catch fire - to keep warm, when the leccy cuts out due to the wind.
Well that's me sorted then - we've got a diesel car which is much more likely to self combust than an EV although the blaze might not last as long as the expected rain will soon douse the fire.

I have yet to see an EV on fire in the sodden freezing climate that is the West of Scotland haha
 
I thought this was an Electric Car thread. Seems to be straying more than a little...
Good point and as its now too late to remove previous heating posts can i ask members to open a new thread if they want to discuss heating and allow this one to get back on topic of EV's, thanks.
 
A month in to EV ownership and I couldn’t be happier. The Kona is comfortable, refined, and just makes driving easy and very low stress.

More importantly, the wife is thrilled with it too.

We’ve got a long drive to do for Christmas, which will be interesting. I’m planning some places we can stop off the motorway as I’m expecting the chargers at services to all be in use, but I’m also expecting that issue to be rare and will improve in time.

Yep, 6 months in only thing I done to mine is replace headlight bulbs as they failed upgrade to led is awesome. Great little car the reverse camera on mine fails does not bother me has good mirrors

Have a look at the Tesla subscription so you can use Tesla's SC network.
Not all sites are opened up to other manufacturers, but worth looking if there are any on your chosen route, as they are plentiful and easy to use and generally cheaper

The superchargers have a similar issue to the charging network in general - they don't have enough at the hotspots between major destinations, so they don't open them up to non-Tesla owners.

For example on the London-Manchester route of M40 and M6 there are 8 or 9 supercharger sites, but only three are open to the public, and only one of those is near Birmingham that is the natural stopping place. That one site is a Tesla servicing centre on an industrial estate in Solihull where the other facilities appear limited at best.

There's plenty of places we can charge so we'll get there, but I still expect plenty of headlines of 'Chaos of chargers during Christmas commute' in the Telegraph/Mail.
 
Just don't get a VW they are going back to ice, that's if they don't shut down all together :laugh8::coat:acheers.

There will be a few of the legacy carmakers that will disappear because they're unable to keep up. Think of all the British car companies that used to exist. Bit early to be predicting VW's demise though.
