We recommend all TRV’s are installed on the flow, rather than the return pipework of a radiator. When used in conjunction with a system automatic bypass valve, this thermostatic valve can be installed on either the flow or return in any orientation. System automatic bypass valves are a specific building regulation requirement for all new installations and boiler upgrades. All bi-directional TRV’s from any manufacturer require the bypass valve to function correctly and thus avoid radiator hammer.
