Open ch system converted to Combi

[rich42]

I have had my 25y old open ch system converted to a Combi system. The guy that quoted the system said it would be flushed before doing anything.
Anyway, the guy who tuned up, ( i think he left his horse tethered to his van) did not flush the system, amongst other things i wasn't happy with.

He allegedly put inhibitor in the system but the boiler manifacturer says inhibitor is not nessesary.

Could i have problems in the long run?

which boiler ?

it is hard to speculate if you will have an issue.

If the system has weakness, elevated system pressure will require regular top ups else system may not work reliably plus system corrosion increases due to regular pressurisation

System sediment concentration could effect hot water delivery for a start.

Gas line most often needs upgrading.

Do you have a room thermostat fitted or just the clock to control the boiler. If no thermostat then you may not have boiler interlock

Check with manufacturers if your boiler has been registered.

Did the installer give you the boiler literature and is the Benchmark filled in
