Why heating controls matter
Heating unused rooms is pure waste. Smart TRVs and zoning let you turn down bedrooms during the day and living spaces overnight, squeezing more savings from the same boiler.

Match valve bodies
Smart TRV heads fit most standard valve bodies, but check compatibility or budget for adaptors.

Consider a hub
Some smart TRVs need a bridge; factor that into the total cost for a multi-room setup.
