Hi there everyone, with the colder months fast approaching, can we pick members suggestions as to the best source of heating for our Leisureline? We want to use it more but currently have no heating except when on 240v. Look forward to hearing your suggestions. Thanks.

Most people here will recommend diesel heater. They are reliable, produce plenty of heat and have a low running cost. Most models are 'blown' - the have ducting and run a fan to distribute the heat. These can be installed by anyone. For a caravan you do need to install a diesel tank, and the tank needs to be maintained if the heater is not used (diesel can get a bug in it that blocks filters. The only down side of diesel is its messy if you spill it, so the tank installation needs to be carefully though though to enable easy filling and draining.

An alternate is gas which is regarded as an inferior fuel for temperature below about 5C. You can get blown heaters, similar to the diesel ones, or water radiator heaters. Installing a gas heater needs to be done by a registered gas fitter and is covered by fairly strict regulations. This means a gas heater will be safe.

We have a Gas heater in out UK caravan. It works fine and pups out more than enough heat. Despite living in the south island have not had a problem with the bottle freezing - but we don't use the van much in the real depth of winter. We have used it a few times in sub zero temperatures with no problems. If installing a new heater I would be going diesel.

A diesel heater is probably the best when you are off the grid. There are a couple of well known and well proven german makes and quite a few similar (copies) available from china. The german ones are quite expensive, whereas the chinese-made copies are much cheaper. The installation is relatively easy for a DIY handyman taking his time. Most manufacturers provide 2 models: a 2.2kw and a 4 or 5kw model. Most caravaners find the 2.2kw heater quite adequate. The diesel heaters are very fuel efficient - from memory, something like 0.1 litres per hour for a 2.2kw heater. There is a Christchurch retailer selling, and possibly installing, one of the chinese-made heaters.

Some vanners use LPG, after all most vans already have LPG bottles. But there are a couple of negatives with LPG installations. Firstly, it is not DIY - the heater has to be installed by a registered gas fitter. Secondly, LPG in NZ is comprised of 2 gases - 40% butane and 60% propane - and in cold climes, like the South Island, the efficiency of LPG heaters is compromised by the cold outside temperature. Another disadvantage is that the heater will be subtracting from your cooking and water heating gas supply = more frequent gas refills will be required.

Hi ,in our previous m/h we had a gas blown heater ,on its own settable thermostat , 2kw ish ,was efficient ,quiet and did not use a lot of gas at all .Our caravan has a 2kw diesel heater ,have had some smell from it ,it seems a lot noisier ,but is equally efficient too , On balance up to yet(only used a few times) i`d prefer the gas . A question for those with diesel ,you say diesel gets a bug in it ,so as we have only a 10ltr tank and its very easily accessable does it need to be drained periodicaly and if so how often please . Cheers Andy .

Diesel 5KW heater on AliExpress is only NZ$250 delivered, and around 2 hours to install for any competent DIYer.
Lovely and toasty in my 8m bus :TU
