Was there something I missed in the steps I outlined? :O Please let me know. icon_smile.gif

like having to turn rads on and off and the need to rebalance afterwards

balancing the rads is easy enough


This is something i'm not sure about. How does I balance them? It is where I use a key to let out air of each radiator OR do I need to do something with the boiler?

you balance the flow through each rad with the lockshield valve

and if you have to top the boiler press up you dont need to turn the water off just the boiler icon_wink.gif


I've got no idea about this. Please explain what you mean.

boiler is on a pressurised system you only need mains water to top the pressure up afterwards

1) We had a new boiler installed about 2 months ago and I was told to make sure I get it done

who told you that?

During the time of installation, I was telling the engineer about the bottom of radiators being cold and top being hot. He then reccomended getting a powerflush.

I told him i'd get it done and hire a machine so as a favour he put the chemicals into the boiler. The idea being that if the chemicals sit in the system for a while that it would enhance give it more time to work before I eventually ran the powerflush. However, he also warned me to make sure I get it done because if not flushed out, the chemicals would affect the life of the boiler.

Did the installer flush the system before fitting the new boiler?

If not, the system will not have been installed in accordance with manufacturer's instructions, which will invalidate their warranty.

Which chemicals did the installer add to the system?

its the installers job to make sure the boiler is installed on to a clean system. He hasn't done you any favours, he should have flushed the system before installing the new boiler.
