catalytic gas heaters (1 Viewer)

[pappajohn]

does anyone understand the workings of them ?
i know HOW they work (basic chemical reaction i believe) but not the materials used.

i have a small heater in the RV which doesn't seem to output a lot of heat.

if i hold in the 'start' button the 'matting' appears to glow a little brighter but is extremely patchy.

could this be the catalyst is coming to the end of its life ?

Hi PJ, willing to bet I know what it is..
See, having Gypsies in the family does help sometimes....
It is usually caused by using automotive LPG..

As you proly know it has a tiny amount of lubricant in it. That tends to build up over time and eventually partially blocks the ruddy jets.

What the travellers do is take em apart, back blast em with compressed air for a while and refit.. Almost every time it works spot on and your good for another few years :thumb:

cheers John, never gave that a thought.

i thought it would be the catalyst 'pad' was losing its platinum content.

of course, its spent all its life running on autogas so it could be the problem.

got some precision jet probes somewhere so i'll give the jet a clean and see what happens. :thumb:

if that dont work i have found a replacement which is a similar size and wall mountable.

Hi John,
I know they have been mentioned before but if you ever get to Spain or happen to see one for sale on Ebay etc these Butsir catylytic heaters are excellent and a good bit cheaper than the minicat you are looking at.
A 3kg camping gaz bottle will fit if only in UK.
We always leave the roof vent open slightly and never really had any condensation problems. Never left it on overnight though but great for keeping RV warm if electricity is a problem.
