Types of connections

Purmo LST radiators can be fitted with two types of thermostatic radiator valves:

Close Coupled TRV Kit (UK Patent No 2259758)

Suitable for TBOE or BOE connections.
This arrangement offers a choice of positions for both the valve body and sensor head.
The kit allows the thermal sensing head of a PURMO Thermostatic Radiator Valve to be mounted directly on the top left/right hand side of the LST enclosure. The point of fitting has been half-sheared and requires only to be knocked out to facilitate easy installation, becoming an integral part of the appliance.
The valve body is fitted to the heat emitter and is coupled to the sensing head by a flexible capillary extension lead.

Direct Fit TRV Kit

Suitable for TBOE connection only.
This kit allows a PURMO TRV body to be directly fitted to the radiator, with the thermostatic head projecting beyond the enclosure.
