Space heater burner cleaning

Post by gareth111278 on Sat Jan 16, 2016 10:31 am

I have a 1986 Talisman with a Truma space heater. Does anyone know the best way to access the burner in the space heater?
I need to clean it, the flame looks poor throiught the viewport & the output is poor.
I've removed burners from below before but its far from easy. I know the burner is housed behind a narrow panel below the heater but it still looks tricky!
Is it possible to remove the heater exchanger to clean the burner?Cheers Gareth

Hi there,

Before dismantling the heater just check the "kg/hr" on your gas regulator and check the requirements of your heater.

A lot of regulators won't put out enough gas to allow the heater to work efficiently so if a previous owner (or yourself) has installed a low "kg/hr" regulator the heater won't be getting a sufficient volume of gas.

Hope this helps. allthumbz

Hi Dutto
Thanks for the advice.
I had a little peep through the flame viewing port & the burner looks like new.
I'll check / replace the reg.
Does the physical size of a regulator have any relation to its output?

Hi there,

Not really, but they usually get more accurate and more expensive as they get larger.

Thank you, very informative, It was quite cool when I used the heater so maybe I wasn't getting the best from the regulator.
I'll replace it with the newer one on the BBQ & see what happens, if it's no better I'll get a 'bigger' one.
I'll check the potential maximum demand of all the appliances before I order.
Cheers for the advice
Gareth

I assume you are using propane this weather, and not butane gas !!      Whistle1

I'm on butane but I thought it was OK in temperatures above freezing?

I believe it gets a bit sluggish below +5 degrees centigrade. Gassing gets increasingly difficult the lower it gets..... scratch head
That's my understanding of it......... shrugg   could be why its "quite cool"     scratch head
Someone will most likely tell me I'm talking out of the top of my hat...........But Hey !  You don't want to strip the heater apart, unless you have to... cold

The experts will be along shortly to advise you on the actual temperature that butane causes problems. I believe it to be several degrees above freezing point. With that in mind I only use propane for all of the year. That way there is no problem with the gas supply.

I think I'll replace the reg & see if its better, I've no idea how old it is. If that doesn't help My dad taught me the trick of putting a hot water bottle on top of the bottle I'll try that to see if its just too cold for butane.

I always ran propane but this van came with 2 x 4.5kgs butane
bottles , so I stuck with them.

Useful info at link above. I use propane all the time. Whatever the specs say Butane is unreliable under +5°C

Mea Culpa!!

It never dawned on me that anyone would be using Butane in the winter. Sorry!!

As a general rule, insufficient Butane will boil off to satisfy a heater at any temperature of 4 degrees celsius or below; and actually stop boiling altogether at -4 degrees celsius.

The problem is exacerbated inside a small cupboard because even at higher temperatures there is insufficient air to allow for an effective heat-exchange.

Sorry, but I would move over to Propane; which will keep boiling all the way down to -44 degrees celsius!

Hope this helps. allthumbz

To be honest I've never used it in such cold weather , my son was at a party so I decided just to take him in the camper, go for petrol and park up to wait for him to phone. If we use the van in cold weather in earnest I'll switch to propane
