Typical price for adding Corrosion Inhibitor to a central heating system?

[adrian816]

Hi,

I've had some work done on my central heating system (which has 4 radiators) and need to have new corrosion inhibitor added. What's the typical cost of someone coming to do this - it's a new system (7 months old) so I'm not sure that it needs flushing.

thanks, Adrian

Hi,
it deffinately requires flushing with a cleanser to get rid of the manufacturing oils & swarfe from the rads. Then add inhibitor.
This should have been done by the installer.

if you are unsure what has been done on install then you want to run a cleaner through the system then flush and fill with an inhibitor added. Its 3-4 hours work min plus chemicals.

as reguards cost it depends on what engineers in your area charge, get a couple of quotes.

to be honest the original installer should flush and add inhibitor as part of the install, this is standard practice and required by your boilers manufacture to comply with its warranty.

Thanks for your comments. The system was cleaned and flushed by the installer. When a service engineer came on Friday to replace a radiator valve the system was drained. I asked about inhibitor and was told "don't worry" but as I want the system to last I'd like to get the inhibitor replaced. Would the system need to be flushed?

not for what hes done but he should of added inhibitor when he filled the system back up

The system shouldn't need flushing again. It's good that your thinking about the maintenance of your system early on.

Inhibitor should definitely be added, what area of the country are you from? Perhaps someone local from here can give you a quote.

If you buy one of these it is a simple diy job to add it through the filling loop or an airvent.

If you don't feel confident to do it get someone in. It won't be expensive.
The guy who drained the system should have added some. The system won't need flushed if he just replaced a rad valve.

As has already been said, it wont need flushing and its not a very difficult job to do so shouldnt cost much. Call a couple of local companys to get some quotes.

one hour of min charge plus inhibitor so arond the £70 mark

Hi,

Did the work involve draining the system? If so, the person who did the work should have added inhibitor when refilling. Ask him to do it on the basis that you will pay for the inhibitor but not for his time.

You should also check the Benchmark log (usually in the boiler installation manual) to make sure that the system was flushed and inhibitor added when the system was originally installed.
