Hi due to get a new boiler (ideal logic ) fitted and at the moment towel warmer has normal valves fitted and rest of house has trv’s but also there is a manual bypass fitted (gate valve) between flow and return. So 2 questions can I remove the manual bypass (gate valve) and can I change the towel warmer to trv’s and would the boiler bypass work or should I keep the towel warmer as standard valves ?
