UK sites with metered electricity

As for outfits using 20Kw or 10Kw that would be impossible. 10Kw would draw over 40amps and 20Kw over 80amps.

How so? the post relates to a days usage, and quite possible to have the 2kW heater running for 10 hours or whatever in the depths of winter.

despite what some say on here, 900w is pitiful to try and heat a large MH or caravan when it's freezing outside..

I disagree, I've now idea about heating a MH and wouldn't resume to talk about them and perhaps a MH with all that glass in front to lose heat out would be pitiful? We have always had a large 6 six berth caravan and after warm up 900W is more than enough. In fact the heat thermostat is often at 3 out of 5 otherwise we're too warm, and yes that was was it was cold enough to freeze the water tap at the bollard.

I am certain you know what you talking about for MH but as you have never owned a caravan or even stayed in one how do you know?

Ive stayed in many caravans, actually. Doesnt change my view

Youve twice said 'after warm up'....what do you 'warm up' the van with?

yes,  900w can maintain heat but ill wager it will find it a struggle to heat a stone cold caravan or MH to a comfortable temp when its below freezing outside.

we have underfloor heating, double floor insulation but heating from stone cold is asking a lot from 900w...

Just my opinion.

We have owned caravans, two of them. The first a 2004 Abbey, made by the Swift group, had the old truma blown air system with a convector fire below the wardrobe. This as well as keeping your coats lovely and warm, kept a fairly small van toasty on 900watts, once everything was warmed up, in all but the coldest weather. I don’t know what the insulation level was but the van was old style construction.

Our modern construction much larger 2014 Unicorn Cadiz with Alde heating was much different. Although the heating generally kept it lovely and warm, it did need the 2KW setting in cold weather. Otherwise it wouldn’t maintain 22C day 18C night.

Our MH has a Truma combi blown air, in cold weather 900watts isn’t sufficient to keep it pleasantly warm and the E2 1.8 KW setting is required. As long as the silver screen is used, I don’t think we loose a lot through the screen and front side windows. Overall I think we have less window area than our  Cadiz.

Whether you use 900w or 2Kw to maintain a set temperature is irrelevent. What it really means is the 900w heater will be on longer than the 2Kw one. End result is more than likely they consume the same power (Kwh) for an identically insulated van.

Thanks Whittakerr for pointing out the obvious regarding site metering. In terms of consumption we are talking Kwh (units) rather than outright power drawn otherwise I agree even 4Kw would trip a 16A outlet

"We warm up the van with 1900Kw". No wonder it warms up quickly...

im sure you meant 1800w or 1.8kw or the EL2 setting?

my point was clearly referring to heating up from stone cold, not after 'warming up'....with nuclear power😉
