I'm getting my CORGI mate to install a new boiler after Xmas. He suggested that to save a few quid I could drain the system & add a cleaner, then drain & remove the rads & flush them out with a hose.
It occurs to me that if I going to do that I might just as well change all the rads anyway. We have 5 double 1300 x 600 & 3 single 600 x 600 rads which must be 30 years old.
Looking at the Screwfix book I could replace the lot for under £400 inc TRV's.
Are the Screwfix rads OK?
