hi i live in flat, had combi boiler fitted, no hot water coming through to kitchen unless you put hot water tap on in the bathroom, which is next door to kitchen?
so these two types of trvs can b fitted where you can not identify which pipe is the flow or return? ie no rads on the wall just 2 pipes from floor in each room so can not turn heating on to identify flow. thax :?:
Does it really matter the size of rad i.e double single length etc as i would like to change all my 9 single rads to double i have a worcester 28 combi
