    Common as muck they used to be, now as rare as hens teeth..

    Looking for a small flue-less type about 300mm wide

    hi i have two ,one is 750wt the other is 800wtboth just under 300mm , one 12ins square the other 10ins square. . all i would say is is that enough they work in a vw . how big do you you want to put it in . my trailer i have 1,7kw . they are old but work . tenner each.
    you do see them on some of the caravan leisure stores . thermex arent making them now but others do.
    i also have a blue flame thermex . my mate uses one in his truck but not as good as a catalitic . they were cheap though . not for leaving on overnight etc.
    try danfast leisure . or pm me if you want more info. 2.8kw and 4.2kw.does have a co ,co2cut out. he finds it works great . i bought one as well ready for my next truck. danfast do other things as well for campers dometic stuff waeco shurflo.

    I had never seen/heard of these before? What are the advantages/disadvantages of this type of heating?

    It looks interesting as a compact heating system instead of a big combi Truma boiler... Are they more efficient than blown air heating? do they use much current on 12v Side?

    Lots of questions sorry...

    Had them in several caravans.. work on the same prinicipal as a vehicle cat converter

    Advantages

    * they don't need a flue or any complex installation..
    * produce no CO or other noxious gasses
    * no naked flame,
    * don't use 12v.
    * compact.
    * silent

    They do burn oxygen so small amount of ventilation required

    can't really think of a disadvantage .. ideal for off grid camping ..

    Thanks for that Mark... That is the one but I am looking for a second hand one..

    Cheers Peter, but that would just look weird nailed to the wall and folk will keep bumping in to it ! :Wink:

    Yup !!! It is not for use as a main form of heating but just to keep the chill off at night when we are wilding.. Def interested in the 800w one Alan,, can you ship it and how would you like paying ?


    Thanks to Jim for replying to Karl.. Appreciate it :thumb:

    Indeed, and it is due to the huge amount of built in ventilation my bloody van has got that we need the thing !
    Considering the van is supposed to be fully winterised and with a 6" a 5 layer floor I have no reason to doubt that, it has vents fitted that you could pass a small bloody cat through ! ( with enough hammer work on said cat and a bit of shoving you understand )

    Never had one cause excessive condensation though.... Not saying one wouldn't just own personal experience has never seen it happen

    yes, water vapour is produced.. so does cooking, washing .. breathing

    I acknowledged that it needs ventilation.. but you can't live in a van with no ventilation .. (heater or not).. we use o2 and exhale co2 .. same as a cat heater.

    I was talking about them the other day. They are great little heaters but I am not sure they are officially recommended these days though

    hiya jaws ,pm me .i,m sure i can post it .
    i use my thermex if in the snow etc when away. yes it can cause condensation . but i prefer the warmth anyway. i used to pick them up years ago in northern spain from the factory . .the two i have here are made in uk or where . i have spoken to the places but they dont make them now . .its abit like instantanious water heaters .i get them in maroc .
    i was keeping these two but seems i shant use both . i,m sure this one will suit you..8kw (2700btu hr )butane or propane . made in twyford berks.
    these days every thing as gone fancy .
    i still have gas lights in the trailer they are great . light heat and help keep mozzies away.
    have fun .cheers lan
