Mark bought an Eco-58-1800-20 collector, an AX controller
and various other parts for his installation. He writes:
"Dear Eco-nomical,
It has been a while since I bought my panel and various
fittings from you in January but I just wanted to let you know how it is
going. I am not normally one for economising but I decided I wanted to go to
solar heated water in the most cost effective way possible so that I could
recover the expense in the shortest timeframe. To that end, I invested in a
58mm x 20 tube panel with a no-frills Resol AX controller, an 18 litre
pressure vessel, a Caleffi air separator, a standard central heating pump and
small domestic radiator in the loft as a heat dump if required. I saved money
by installing the system myself and as I had already installed a 200 litre
solar cylinder previously i thought the rest of the job would be relatively
simple. It was straightforward but I guess if i am honest it was very hard
work especially if you lack a head for heights! I had very restricted room to
work with a small airing cupboard already dominated by the cylinder and loft
that could bearly be accessed on hands and knees but I squeezed it all in.
The results; very impressed. I have had no teething
troubles, no leaks, the air separator works excellently as does the controller
and it is really rather dull in that everything works as it should! The only
fly in the ointment was that extra turn of the screwdriver on one of the tube
clamps that I knew I shouldn't do and sure enough... crack. So at some point
I will need a new tube and will also need the overvoltage protection device
that you didn't have in stock in January. However, I finished the
installation at the end of April and it has provided all of our hot water
since, fantastic...just in time for yet more gas and electricity price rises.
Regards Mark
Well, that is the sort of dullness I can live with! Thanks for the information, Mark.
