My gas water heater has sprung a leak. I managed to fix it with
self-tapper and
teflon tape for temporary fix. But I wanted to get solar to replace it
Can anyone suggest the best value brand to buy?
Should I go for stainless steel tank?

Solartech Genius


product description -


It comes in a 200 lt or 300 lt version, is made from rotationally moulded
plastic, can be electrically boosted as well as 'wetbacked' off a
woodheater, no rust problems (being plastic), hard water won't cause mineral
build up (nothing for it to 'bind' to), doesn't need frost protection (safe
down to -20C) and is light enough that myself and 3 mates carried it up on
my roof and attached it.

sales agents -


I'm as happy as a pig in the proverbial with mine.

After rebates and installation costs (in my case the plumbers had to do the
wetbacking to my woodheater as well), it came out at roughly $000.00

 Thanks for the info.
I am getting quote now.
Quote I had from solhart was nearly 5,000
(as i dont get federal rebate)
There does seem to be a lot of trouble with some of these system with
either aluminium or stailess steel tanks.
does the tank have the fittings (bungs) to make it easy to install
a booster such as wood fire or gas?
Not familiar with the term - "wetbacking" - what does that refer to?

thanks again for info

The woodfire connection is done just before the pipe enters the hotwater
heater (my plumber built the connection).

Not sure about gas boosting, you are probably best asking the makers about

Wetbacking is a connection into the back of a slow combustion wood heater,
where a down pipe brings cold water down into a grid of pipes in the back of
the heater, and a return pipe takes the heated water (heated by the fire)
back up to the hot water cylinder by thermosiphoning - it means that, in
summer most of your hot water is supplied by the sun, in winter most of your
hot water is supplied by the wetback/fire.

No problem, I'm very happy with mine, at a guess (depending on where you are
etc), I'd say you will pay about half of what solarhart quoted you, for
info, my heater is only barely high enough (according to the manual) to get
an adequate water pressure, I'm not unhappy with it - but if you like your
hot water at high pressure and the height is borderline, consider getting
the 'high flow kit' (a pump).
