Im about to purchase and fit a large central heating system based on an oil combi boiler. :(
Im buying fairly basic convector radiators, choice based on room requirements. im very confused about the huge range of TRVs available and the associated wide variations in price of these on the market.
Apart from looks, can anyone guide me re what features, brands or types i should select? wax? TRVIIs? Im aware that these are a good feature for heating control but in my expeience rads are either on (max) or off!!
please advise
:) thanks
