Who thinks it is a good idea not to use chemicals in their heating systems?

Answer 1

Rickster and Drive Rob have the right idea.
Water in a central heating is very corrosive as it is heated.
The pH of the water is usually slightly acidic below 7 ( neutral) so it makes sense to increase it above 7 to make it slightly alkaline.
When water is slightly alkaline it tends not to corrode metal, and chemists have been working for years to counter corrosion, FERNOX chemists noted that iron bars wrapped in old sack and buried in a tree had been there for hundreds of years, and were still like new. The explanation being that the tannin in the bark somehow preserved them .Government establishments use fernox to preserve their central heating systems.
No black indian ink comes out of a radiator treated with inhibitor.
Magnetite is the black sludge as a result of corrosion.

Answer 2

Some heating systems require chemicals, i.e. a boiler needs water treatment for corrosion prevention.

Answer 3

I dont

using a rust supressant in a central heating systemn improoves the heat transfer, reduces build up of corrosion and magnetite and extends the life of th system.

if you are going to leave the property occsaionally then addeing an antiofreeze nmay be a smart move

Answer 4

If you don't have any (special) chemicals in your CH system then the water, and the minerals it naturally contains, will react with the copper/brass/steel in the various parts of the system, corroding and clogging them.
Typically, black, insoluble iron oxide powder will form, circulate and build up in the lowest parts of the system.

Answer 5

Actually avoiding chemicals in all the aspects is good;but we can't do it.

Answer 6

you should put central heating protector in it it leaves it cheaper to run and your system will last longer
