I have ran LPG at around 0 to -20 just as normal for several weeks at a time.
(the gas was turned a little lower than in summer)
This is my first winter without running gas for years.

A very strong battery & a Quality Jump Start booster ready just incase cranking fast enough is a problem.
Especially important to run the correct oil for low starting temps.
(i never, just used 20/50)

Engine tuned properly, timing set,
quality plugs & leads.

A good anti freeze ratio.
Keep the air filter dry. (possibly have 2 to swap about,
use one & then take it in to dry over night)
Everything kept clean & dry as possible under the bonnet when temps rise & you can get condensation.

Kettle of boiling water over the vapouriser on a morning.

ah thats good news ebay has served me well.

ive already replaced the coil, gone for lpg spec ht lead.

new dizzy cap and bocsh super 4 plugs to be fitted at the weekend.

The kettle trip has been used more than once this week Very Happy

Battery is questionable, i have been eyeing up a twin battery system.

The viscous fan made me think to, the last thing the vapouriser needs is to be cooled by a great fan when your trying to keep it warm. Laughing

When its around -10 or lower you learn rather quickly not to go around using boiling water, (anyplace other than in your drink)
well not if you intend using the vehicle often.

(warm possibly,
but if you are staying out in the very cold its a liability,
& boiled water freezes faster & very hard in my experience,
& i knows its said to be a myth that boiled water freezes differently from cold water)

Insulation is the last thing the vapouriser needs, it's the LPG vapourising that cools the vapouriser as it turns from liquid to gas. That's why you need to run water through it to stop it freezing even on a hot day. Put an insulating jacket around it and all you'll do is keep the cold air in and stop it warming up.

Insulating jacket is a good idea, to keep off cold wind, and preserve what meagre heat you may be getting from the coolant flow.

The vaporiser would never work from heat exchange from air alone, it relies on the water flow. Even water at -10C will "warm" the vaporiser core enough to work, if you circulate enough of it.

Do not obstruct the vap's diaphragm breather hole with insulation. Do not pour water into the breather hole, either; it may freeze.

A mass of hot water can freeze faster than cold because of internal currents

Has anyone tried?:

- Polish flat side of vaporiser to a shine (and seal edges with silicone?)

- Apply a a spot of this:

- Add one of these:
http://cgi.ebay.co.uk/320W-Cooling-Peltier-Ther...sh=item230d9910eb

- Strap on a heatsink with a big jubilee clip (also seal heatsink to peltier?)

- Add a simple timing circuit and relay onto the peltier for the length of time it takes coolant to get to a good temperature (say, 10mins)

- And a master switch so you don't drain the battery when pulled over with the ignition on.

Would it provide sufficient heat?

Unless you are looking for a sub -20C solution, it's much simpler just to give the vap some thermal mass to tide it over until the coolant warms up a bit. Simply, use a physically big vap and make sure it has a good water flow.
