RECIRCULATING SYSTEMS
The mono-block manifold has a blanking cap which when removed acts as a return port for a recirculating ring main. Contact us for ring main setup or design advice.
DIRECT MOUNTING OF THE TEMPERING VALVE
Notwithstanding acceptable methods detailed in G12, the manufacturer Caleffi has specifically engineered this tempering control valve to directly mount onto the hot water cylinder with no minimum pipe length isolation requirement as an alternative method of achieving compliance.
