I’m replacing the radiators throughout the house from the ancient and starting to rust to modern type 22's but nothing fancy. Which brands stand out as good quality and what should I avoid?
My preference based on 25+ years of maintaining and upgrading my own heating system is Myson Premier radiators. Much heavier and better quality than others I have tried in the past.
It's important to use quality TRV valves too. Drayton TR4 are what I use.
There is not much difference between mainstream radiators it's more down to the water (inhibited) inside your system and the amount of oxygen in the water.
Myson being one of my least favourite due to the amount we have replaced due to bad paint and from years ago when they fitted air vents on the back face of the panels, and they supplied a pressed steel spanner as a key wouldn't fit, so customers could snap off the brass vent that that caused the rad to be scrapped. Stelrad used to be the brand we mainly fitted, they were more expensive and the B&Q and Screwfix ones seemed just as good.
There's a lot to be said for rads with separate air vents and plugs that can be easily replaced if necessary.
15 yrs in, Screwfix and Toolstation ones still look in good condition on the outside - running inhibitor and filter not dragging anything out of the system, so I assume the internals are too.
stelrad for me im not a lover of myson rads but to be honest there all roughly the same
some buy weighty rads but dont want to pay for a second person to fit the rads onto the wall for the same amount of money
when upgrading the rads watch your btu to boiler ratio you can change a double convection rad to an enclosed rad and still use the double convection rad btu number
but changing a rad from a double single fin rad will cause a higher btu
weighty rads take longer to heat up but take longer to cool down more so if you use cast iron rads
