I want to fit some TRVs throughout the house. Do I need an automatic bypass installed if I don't have a TRV on every radiator? I won‘t have one in the hallway, kitchen, and upstairs ensuite.
Further to that, if I do need one, do any boilers come with them pre-installed? I have a Worcester Greenstar 30si combi boiler.
Thanks in advance!
