I have a very tight install for a new retrofit Heat Pump and was wondering if I can have a Spirotech mb3 filter between my unvented cylinder and the T of to my expansion vessel on the return for my heating circuit or is it better to put it on the flow???
Spirotech MV3 filter between Expansion Vessel and Unvented Cylinder
- Thread starter myatix
- Start date
On the return after the last rad wherever possible to maximise protection of the boiler
