203646-E16 M2 Heat Exchange Unit 16kW c/w 3 bar security Unit

The E16-M2 16kW Heat Exchange Unit is a compact, pre-assembled hydraulic separation solution designed to safely isolate distinct heating circuits in domestic and commercial hydronic installations. Engineered with a high-efficiency stainless steel plate heat exchanger rated up to 16kW, this unit is ideal for separating primary boiler loops from secondary underfloor heating zones, biomass systems, thermal stores, or sealed/vented heating boundaries.

Equipped with an integrated 3 Bar Safety Security Group—including a pressure relief valve and system pressure gauge—the E16-M2 provides reliable pressure protection and effortless monitoring in a single, space-saving assembly.
