Flushing Out Radiators

coolmen

I am installing a tankless boiler and the house has convectors and radiators.I will flush out the system befor firing up and some one said to install a inline filter. Is this a good idea to protect the new boiler of grim and rust?
has any one done this? what about preassure dro?
any thoughts on this
thanks.

After power flushing systems in the UK we used to install a high power magnetic filter. The machine we used to flush the system with also used the magnetic filter and the water would go into the flush pump black then leave clear just because of the magnetic filter. This is the system we used but you can also get a system you install in the return line for the rads. Im sure they must sell something like this in the US.

Here's the system you install. They must have a US dealer as they were installed on every system we flushed and were very good way to keep sludge down. .
