    We are considering downsizing from a coachbuilt to a PVC. And because we want a new van with a comfortmatic gearbox and a specific layout, it is likely we will need to place a factory order.

    Looking through the various options list for a Rapido / Dreamer van it is possible to specify 230 volt underfloor heating. Obviously need a hook-up to benefit, but that's frequently what we choose.

    I haven't come across electric underfloor heating in a van before.

    So the question is does anybody have electric underfloor heating in their van? If so, is it any good? And I haven't yet been able to discover what the power consumption is - but suspect not a lot.

    The cost is £390 inc vat. Now although a significant amount of money, and much more than a £20 fan heater or oil-filled radiator, it does have appeal. Especially as we're downsizing and need to reduce the amount of 'clobber' we carry 'just in case'.

    Another advantage could be 'airing' the van in winter when parked at home, and possibly creating a frost-free zone too?

    Any thoughts?

    It sounds great and when I specified our overland van for retirement I plan to have that fitted (although I'm having an inboard genny so it will be the only source of heating)

    So that's the question. If you spec that what is the in motion and off site heating option? We have diesel heating right now and it is great for day trips.

    Maybe better than you thought, I was told we were not insured if I use any electric heater in the van as it's none standard, electric underfloor solves this problem and better than an electric Truma because no moving parts.

    Thanks - that's an interesting point which I hadn't considered! :)

    Oh, and I should have said that the underfloor heating would be in ADDITION to a Truma combi boiler for space and water heating. The standard spec is a Truma 4 (gas only), but we're thinking of upping the spec to Combi 6 EH (gas and electric).

    We've got diesel space heating in our current van, which we like and is both convenient and frugal; but we're not too concerned about going back to gas, especially if there's electric heating back-up.

    We had underfloor heating in our first van, a 2008 coachbuilt Burstner. I wouldn't say it was any good for keeping the van warm on a cold day but the floor did feel comfortably warm and pleasant to walk on.

    I have only underfloor heating in my last house in Port Solent to consider never had it it a van. In the house it was brilliant; kick your shoes off and leave them downstairs and they would be toasty by the morning, and of course hot air rises so you have the benefit of the floor acting like a storage radiator. Go for it.

    Paul - I assume it was 230 volt electric? Do you happen to know how much power or current it required? Watts or amps?

    Got under floor aquatherme system (hybrid of truma and alde) can be run on gas, 230v or a mixture of both. Excellent, especially on the sinuses (I find blown air dries them out ), but as has been said it's a background heat that will keep a warm van warm but pretty rubbish at heating a van from cold.

    As to current, the one on our 12 year old van can be set on the control panel to 0.5kw, 1kw or 2kw hence the choice of being able to use it together with gas. I supposed you set it to suit your EHU.

    Wet water probably a better option as van can be used of grid on gas.
    had a demountable once with Alde heating plus their underfloor heating.

    The best aspect of the underfloor heating was in the shower room

    No experience but it sounds a very good idea. You could walk around in bare feet in winter and have warm tootsies! But I think you would want to specify a secondary system like the Webasto Dualtop for use off EHU and of course hot water.

    The standard heating is a Truma combi 4 (gas only), in addition to the electric underfloor heating. But we're thinking of upgrading it to a Truma 6 EH (electric & gas).

    In a house/building if it's primary source heating then you work on 150 watts/sq m. In a motorhome with far less actual space to heat I imagine you could get away with less.

    That's rather what I thought. But to be honest I've no idea what to expect in terms of heat generated - will if make a significant difference to the 'room temperature', or will it simply be a case of warmer on the feet? Either way, I think it's probably worth a punt. There are plenty of occasions when a little gentle background warmth would be appreciated, but I realise it's not going to sensibly heat up a freezing van.

    If it's a proper primary source kit then you won't need anything else. It has to be fitted properly, what's underneath it is just as important as what's on top of it.

    The thing you need to be aware of in a motorhome is that if you go that route and you're ever anywhere with no, or not big enough, EHU then you have no heating.

    Personally I would recommend an Alde wet system instead.

    hya we have the same system in our hymer, if the ehu is weak we set it on low and it just goes in and out on the thermostat and the biggest bonus is no sound.. unlike the fan blow heater. i would have it again if i could afford it.. works just as well on gas or both

    Problem is, I don't think the Alde wet system is available in a PVC. (n)

    So we'd have to rely on the Truma for serious warmth.

    But I appreciate you point concerning the current available at the EHU - we're used to juggling our appliances dependent on power available. In our current van we carry 2 electric hotplates - one rated at 1,500 watts and the other at just 500 watts. Additionally, we have two electric kettles - a large one at just 1,000 watts and a small one at 600 watts (not to mention a 3rd kettle that goes on the gas!). Also have a Remoska at 400 watts. Two oil-filled radiators - 900 watts and 600 watts - and a fan heater rated at either 1,000 or 2,000 watts. Not forgetting the fridge and the battery charger and all our tech stuff... As I said, we need to downsize and cut back on all the kit!

    It's available anywhere you want it if you're happy to pay for it.
