Hi all,
I am upgrading my radiator to take the wiser radiator thermostats.
I have Myson/purmo radiator s.
I have purchased trv bodies to swap over and want to know if the 15mm compression fittings are compatible?? They look slightly different
Will this be a direct swap, can I use the nuts left on the pipes or do I need to change everything? This would require an Olive puller too get them off!
