Hi there boiler people,

I have a Britony II T gas water heater, like so:

http://www.plumbworld.co.uk/574-2348?PHPSESSID=

It was installed as a second hand unit when I first bought it, and
I've no idea how much use it had prior to me. It's worked fine, and
I'm very happy with it, but [on account of chatting to a heating
engineer some years ago] I have a feeling that the temperature of the
heated water is has dropped somewhat. I'm aware of seasonal
differences in performance, but coupled with it's age and the fact
that I live in a hard water area, I am wondering if performance might
be enhanced with a descale?

Is this possible to do this job without a circulating pump? -
[obviously, with the heat exchanger removed]. Or can you hire such
pumps yourself? And if so, what about a suitable chemical to work
with?


Thanks
Garry

Before you waste a lot of time and effort on this exercise take a look at a
new replacement price and decide if its worth the aggravation to end up with
an ageing lump

You can hire one from Acorn Gas Supplies in Leeds £50.

You can buy the solution these days. In instructions for Britney the Hydrocloric acid formula is given, think it's 5 water 1 acid.

one main problem with Britneys is worn diaphragm, costs about £5. Very important to lubricate the pin with silicon grease. In failure mode the boiler stays fired up after hot tap is turned off. Very quickly heat and pressure is sufficient to blow apart the first joint after the heater and fill the room with steam.

Apart from that they are dream machines.
