Vaillant TURBOmax Pro 28/2 E DHW Plate Heat Exchanger 189mm 065123
Product Overview
The Vaillant TURBOmax Pro Domestic Hot Water (DHW) Plate Heat Exchanger (Part Number: 065123) is a replacement heat transfer component associated with selected Vaillant heating systems.
The plate heat exchanger transfers heat from the boiler's primary heating circuit to the domestic hot water supply without allowing the two water circuits to mix.
The 189mm plate heat exchanger is designed to support domestic hot water production by transferring heat efficiently between the two separate water circuits.
ℹ️ Product Condition Options:
This part may be available in New or Refurbished condition. Please select your desired option from the dropdown menu above. Refurbished components should be professionally inspected, cleaned and pressure-tested to confirm correct operation and integrity before installation.
Technical Insight & Common Failure Symptoms
The domestic hot water plate heat exchanger consists of a series of metal plates that provide a large surface area for transferring heat between the primary heating water and the domestic hot water circuit.
Over time, heat exchanger performance may be affected by limescale accumulation, internal restrictions, corrosion or leakage.
Possible symptoms that may indicate a plate heat exchanger or associated hydraulic system problem include:
-
Domestic hot water failing to reach the required temperature.
-
Fluctuating hot water temperatures.
-
Reduced hot water flow caused by internal restrictions.
-
Hot water taking longer than expected to heat.
-
Reduced heat transfer performance.
-
Leakage around the heat exchanger or its connections.
-
Unusual pressure changes associated with an internal heat exchanger leak.
These symptoms do not necessarily confirm a faulty plate heat exchanger, as similar problems may result from temperature sensors, diverter valves, water flow restrictions or other boiler components. Correct professional diagnosis should be carried out before replacement.
Compatibility
This part (MPN: 065123) is associated with selected Vaillant TURBOmax Pro boiler systems, including the 28/2 E VUW 282/2-3 range.
Please verify the exact boiler model, original part number, heat exchanger dimensions and connection arrangement against the manufacturer's technical documentation before ordering to ensure correct fitment.
Safety Advice
Boiler plate heat exchangers and associated hydraulic components should only be inspected, removed or installed by a suitably qualified and competent heating engineer.
Always isolate the appliance and relevant water supplies before carrying out any work. Allow the system to cool and safely release residual pressure before removing the heat exchanger. Follow the manufacturer's servicing instructions and complete all required pressure, leakage and operational safety checks before returning the boiler to service.
