Can I ask why you are worried about the cost and safety of installing an immersion?
Even if you got a decent plumber it won't cost as much as other options.
Mine has been working fine for about 18mnts now

Hi Mark
I'm interested in installing something similar what set up you use?
I know a couple of plumbers who would be happy to install it for me
Whereabouts are you mate?
You're welcome to come and have a look
As for it getting cold later in the day - yes of Course it gets colder but its never freezing - and it's never froze - surely that's the point?
I have mine to come on at about 4 in the morning on a timer and the water is lovely and warm and van is nice too
It might take a couple of hours but its surely cheaper and a lot less hassle than LPG/diesel with less to go wrong
