I live in Caravan city, the North Wales coast has one of the most densely populated areas for caravans. The local Morrison's do it he told me.
I was thinking it would be best to have some kind of yearly inspection/service, so a cert for that would be no bother.
Spruce, what boiler would be best, please? I want something reliable and safe, I don't mind too much about the price I just dont want anything unreliable or dangerous.
This is a difficult question to answer.
Someone put a link to a boiler somewhere on one of the posts. Many have used that boiler sucessfully. I know of one that has been in the van for the past 6 years and still works when needed.
There have been others than haven't managed to get the same reliability out of the same model. But as someone once said. at the price buy half a dozen and replace them if one fails.
A few years ago a poster ordered another make from the States for around £160. My guess was that the components were also made in the same Chinese factory. The boilers also didn't have the CE mark which again would be an insurance issue if things went wrong.
A fellow windie fitted one of these Ebay ones and it worked fine with a vent through the roof. Unfortunately the regulator started to leak and filled the van with gas whilst he was working. Thankfully he came back to the van and turned the gas off at the bottle. He removed the whole unit that evening and has gone back to cold water.
I would certainly ask your caravan guys what boilers they recommend. They have much more practical experience than we do.
In our application we need a boiler that will light up with a flow as low as 1 to 1.5lpm. Most tankless gas boilers don't fit this criteria as they are designed to heat water to fill a kitchen sink or bath quickly using a higher flow rate.
