'IMHO the gas shuts off automatically when the flame goes.....'

When you switch the heater on you have to hold the knob down until the flame detector has reached its temperature ( at least thats what I assume is happening).

It must be possable to retro fit a timer if you wanted to, our van is fitted with a 7 day unit as used in domestic systems, ours is an Alde system, but i would have thought they could be used. may cost a packet though.

We set ours low overnight to increase just before we get out of bed, as there is no fan there is no noise.

If the burner goes out it's not burning at all, therefore it cannot produce carbon monoxide which is a product of partial combustion, not no combustion at all !!

When you hold the knob down to ;light the burner, you are holding the gas safety valve in contact with an electro-magnet. The thermocouple heats up and produces about 50mv of electricity which is enough to energise the magnet, this then grabs the valve and holds it open when you let go.

If the flame goes out the magnet should become de-energised within 60 seconds, (usually 30-40secs), the magnet lets go and the valve shuts with a 'cluck' that you often hear after switching off.

As far as mains 240v heating goes, theres no reason why a plug in type timer cannot be used. You will need to cut the 240v supply to the heater to connect in a three pin socket for the timer, a three pin plug then goes on the fire side of the mains cable.

Many thanks for all your replies.  You have provided me with much useful information.

Thanks again,

John
