I have a pressurised (and sealed) central heating system.
I need to remove a radiator upstairs, and this will require draining the entire system upstairs. (Drain valve above boilder in kitchen will be used)
However, when the job is finished I do not really want to use just mains water to top it up as surely this will rust the system? So I guess I need to introduce some rust-inhibitor to the system.
I have no manual (or skills/knowledge) - so was wondering:-
- What product to use
- how much to use
- How to introduce it!
I had a new tank installed by a *cough* professional last year who did the similar drain, but didn't introduce anything (so down 50% on anything that was there anyway).
House is typical new small 3-bed semi
Many thanks indeed!
