Water Plate Heat Exchanger for Espar / Eberspächer & Webasto Coolant Heaters
Product Overview
This water plate heat exchanger is designed for use with Espar / Eberspächer, Webasto, and similar coolant heaters, allowing efficient heat transfer from the heater coolant circuit to a separate fresh water circuit.
The exchanger is constructed with 22 internal plates, keeping coolant and fresh water fully separated while allowing both circuits to flow independently and efficiently heat domestic hot water. Suitable for replace 4111204.
PEX-A Compatibility
The 0.55 in (13.9 mm) outer diameter water connections are ideal for PEX-A expansion installations, ensuring a secure and reliable fit.
The thermostatic valve and connectors are pre-fitted for simplified installation.
