If you have a heat exchanging coil within the higher part of the body of

hard water area but a routine acid flush will prevent problems for some
considerable time. Suitably located valving will ease access to do this.

I read somewhere that as long as the temperature of the water is 60 C
or below, that scale will not precipiate of the water much.

This would explain why kettle and immersion elements scale up, but the
inside of how water pipes don't suffer nearly so badly.

Anyway came aross some links on scaling and descalers:

http://www.electronicdescaler.com/indexx.php?id=22
http://www.electronicdescaler.com/indexx.php?id=31

They have quite an impressive client list and their site doesn't look
like a snake oil marketing job.

This is a wind-up right??

Lord Hall, do you mean that web site is wrong and all those impressive and
highly professional companies do not use the scale reducers?
