Powerflush in new house

Mr_Thrifty

Likely to be moving to a new house soon, and was wondering whether it's worth getting the central heating powerflushed. What do you think? The boiler looks like a fairly old one and I've no idea how well it's been maintained.

Surely first priority would be to have boiler checked for safety and serviced (by someone who is gassafe registered) then ask if they think powerflush necessary

Arbrighton is correct. A powerflush should be the last thing on the list. Get it checked for safety first, then get it serviced and see what the gas safe engineer recommends.

Thank you all very much, I will get the boiler serviced as a priority.

Out of interest, what exactly do they do during a boiler service?

The boiler's manual will have the service requirements.

They check for safety (CO leaks - CO kills!) and clean the burners and stuff so make it more efficient (I'm no expert!)

A powerflush is only needed if the pipework/radiators have clogged up with sludge, meaning the hot water does not circulate efficiently.

So if the boiler is working well, but the rads don't get hot this could be a sign of sludge (basically rust and stuff that can build up in the rads). Another way to tell is to find the drain c*ck and draw off a bit of water from the pipes/rads - if it is black, and gunky, a powerflush might be needed. If it is clear water, no need.
