Worcester Bosch Greenstar Heatslave Boiler Diverter Valve Body 87161087220
Product Overview
The Worcester Bosch Diverter Valve Body Assembly (Part Number: 87161087220) is a hydraulic component designed for selected Worcester Bosch Greenstar Heatslave oil-fired combination boilers.
The valve body forms part of the boiler's diverter valve mechanism, which directs heated water between the central heating and domestic hot water circuits according to the appliance's operating requirements.
This component provides the hydraulic section of the diverter valve arrangement and works alongside the associated actuator to support correct water distribution.
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 valve bodies should be professionally inspected and tested for correct operation and leakage before installation.
Technical Insight & Common Failure Symptoms
The diverter valve body forms part of the boiler's hydraulic system, providing the water passages through which heated water is directed to the appropriate circuit.
Problems affecting the valve body, internal sealing surfaces or associated diverter mechanism may interfere with the boiler's ability to direct water correctly.
Possible symptoms that may indicate a diverter valve or associated hydraulic component problem include:
-
Central heating failing to operate correctly.
-
Domestic hot water temperature becoming inconsistent.
-
Radiators warming unexpectedly during domestic hot water demand.
-
Hot water failing to reach the required temperature.
-
Water leakage around the valve body or its connections.
-
Restricted or incorrect water flow through the heating circuits.
-
Visible corrosion, damage or deterioration affecting the valve assembly.
These symptoms do not necessarily confirm a faulty diverter valve body, as similar problems may result from the actuator, internal valve components, circulation issues or other hydraulic controls. Correct professional diagnosis should be carried out before replacing the component.
Safety Advice
Boiler diverter valve components should only be inspected, removed or installed by a suitably qualified heating engineer competent to work on the relevant oil-fired appliance.
Always isolate the appliance's electrical supply and relevant water connections before carrying out any work. Allow the system to cool and safely release residual pressure before removing the component.
Follow the manufacturer's installation and servicing instructions. Ensure the valve body is correctly fitted, all required seals are in place and appropriate leakage, pressure and operational safety checks are completed before returning the boiler to service.
