how often do you hve to change the water in your central haeting system?

Question

i know mine hasn,t been changed for 7 years, is it damageing my system?

Answer 1

it's best to drain, flush out the water every 5 years, make sure u use a sludge remover before you drain it, the instructions should be on the container.

Answer 2

It shouldn't need changing if it had the correct amount of inhibitor put in on installation. Its a job for the summer if you feel you want to do it. On the lowest part of the system is a drain valve where you can connect a garden hose and run it outside .

Answer 3

It depends if you live in a hard water area or not. Wouldn't do any harm to change it though, except you might be adding a whole lot more calcium to the system.

Answer 4

If you have the proper amount of scale inhibitor in your system then you don't need to change it , However it does no harm to flush your system out each year adding new scale inhibitor when refilling

Answer 5

changing the water regularly would add to the problem of build ups in the system.- usually it happens only when necessary

Answer 6

Best bet is to shut it down and wear longjohns evryday till spring comes. Oh and get an electric blanket as well, for those cold nights.
