How did you get on with your calfont? I am keen to put one in my caravan as well. At the moment i have a burnco 5L per minute califont in a batch and its fantastic. gets temp to 55-60 degress no problem and hardly uses any gas at all. I am keen to put a similar on in my caravan.

Under Current Gas laws you are not allowed a Califont in a sleeping or living area of any structure. That makes it impossible to install in a caravan legally.
This applies even if unit is flued to exterior because a flue will only take away burnt gas (co2) but you still have semi open gas works and the possibility of a gas leak into space

As I've already bought the califont and flue for my bus, please can you quote the reg that bans this option?

I don't have the reg because as all gas work has to be don't by a gas fitter. it was the gas fitter who told me this is not the reg and not only would he not install a new califont he would not fix the current one. Best you check with Gas fitter you are going to use for your gas install. Like most things rules/regs can be taken different ways by different gas fitters

Here are the regulations.

11 General rules for when things deemed to be unsafe....
(1)(d) ensure persons are not exposed to carbon monoxide and other harmful products of combustion of gas....

from this prohibited product notice
"They do not comply with the gas installation standards cited by the Regulations (NZS 5261:2003 (Gas installation)) which prohibit the installation of instantaneous water heaters in bedrooms, bathrooms or toilets" ....

There is no dispute - fitting a califont inside a motor-home or caravan is illegal. I know of people who talked about having one installed into a sealed locker venting outside, don't know if they actually did it though. In theory it would be possible.

Hmmm... So if my califont went inside my gas locker (right underneath) and was sealed from the inside... Presumably it would be an 'ignitions source' and fail to be far enough from the gas source and fail the gass bottle conditions too then?? With 120l tank @10l/m it's a 12 min max burn time... Very unlikely to be a hazard(!)

*sigh* no issue for people who have them, but #%*t for people who want them... Same as the seatbelt rules :evil: :roll:

Also, since it's directly next to the gass hob, it will have the same air circulation as that open flame cooking...soooo, If the rule prohibits bedroom and bathroom, all I need is a door between kitchen/califont and sleeping area and it's then legitimately a different room space?

I survived a califont inside my old campervan for five years. Next our gas hobs and ovens will be deemed illegal.

Matt has pointed out the regulation that says an installation is unsafe if it exposes people to CO.

The regulations also say that a caravan gas installation must be built to the standard AS/NZS5601.2. Section 2 of the standard is mandatory and section 2.9.1 says (in part)
Instantaneous water heaters shall not be installed in bedrooms or areas used for sleeping unless the water heater is of the room-sealed type. There shall be no ventilation openings or other connections between any area used for sleeping and any compartment in which an instantaneous water heater is located if the water heater is not of the room-sealed type.
NOTE: An area used for sleeping includes any combined living/sleeping area
This is a NZ only section, the Aussies ban califonts outright.

The prohibition on califonts is not unique to Australia and NZ, the North American and European caravan codes also do not allow them. So the majority of the western world does not allow their usage.

Why not hobs? I believe it is a risk management thing. There are alternatives to califonts so the standards call for those alternatives. So far nobody has invented a flued hob.
