Caravan Heaters


Hi All 

I am trying to come up with a cheap safe heating option for my 19 ft caravan as all available units are too expensive for our budget. I would like others opinion on the following.

In my younger day's my friend and I  installed a wood fired back boiler in our kitchen which supplied hot water to 4 radiators supplied by 20mm copper tubing coupled to the back boiler with the water feed connected to the bottom of the boiler and the outlet at the top of the boiler. The boiler worked well without a pump and gave a comfortable temperature in even the harshest english winters. I got to thinking if the same principles could be used in the caravan utilising the current water heater and a combination of gas and  electricity heating the water with a hot water circuit going to and returning to the tank via a small radiator. I have 570w of rooftop panels with a 50a controller and 7000w inverter together with 2 9kg gas bottles. Please be honest and tell me if I'm dreaming. Alternatively has anyone got any other idea's

Interesting concept and I guess theoretically possible.  I would imagine however that the water heaters are not rated for continuous use and would have issues with long periods of use.  You would need to check that out. The wood fired boiler would have been on continuously I assume to heat and circulate the water.

This may be of interest...Google     Swift Ecotherm Heater

Or you could make your own adapting a truck/car heater (from wreckers) and connect to your hot water service with small pump

If you are going to the trouble of making that heater it would be just as economical to buy a diesel heater and fit it yourself.

In other recent posts on here the diesel heaters have been listed at a very low price from some ebay suppliers.

You have a fair amount of solar so,
if only just to take the chill off the air you could probably use a small blow heater for short periods or possibly just use an electric blanket.

This form of heating is not going to be as efficient as directly heating the van eg a diesel heater. With a regular diesel or gas heater, virtually ALL the heat from the fuel goes into your caravan. With an external heat source, you will lose heat on transferring it from the fire to the van. This is fine if you are using wood - normally there is plenty of wood available and you would never know how efficient or otherwise the system is, but when you are supplying the heat (gas, electric or diesel) and paying for it, then efficiency becomes important. It is probably better to go for a commercial unit because they have already calculated the amount of heat required for comfort etc. They have done the design work for you.

noThe car heater core is made to run at 15psi, the caravan pump is 45psi, use a OIL cooler preferably a new one . I have installed one works good PM me for other info.
