 Replacing a radiator
Topic Originator: jake89

Looking to replace a single radiator. Straight swap and know how to do it myself. One thing I don't know though is whether the system needs topped up. I had to do this in my old house with a combi but this house has a standard boiler and a hot water tank.

There should be a plug on your outside wall jake that will drain the entire system before you remove the radiator so you don`t flood the place

The down side after you have swapped them is the boiler will keep cutting out until you have bled all the radiators including the one on the pipe in the hot water tank cupboard and the water pump which is a large flat screw head

A stander boiler will fill radiators, but as buspass says you will have to bleed radiators

I did this recently without draining the system. I isolated the radiator via the 2 valves.
Then used a drain kit I got from Amazon for about £14. Was really straightforward and system automatically refilled radiator when valves were reopened along with bleed screw.

Thanks all. Hopefully simple enough to do. If draining down the whole system I'll likely replace two of them.
