What it is

The Worcester Bosch 87161076370 is a domestic hot water (DHW) thermostat control supplied for appliances in the Greenstar Heatslave range. It monitors and regulates the stored hot water temperature, feeding that reading back to the appliance control so the burner and diverter sequence respond correctly. The result is stable hot water delivery and efficient, safe running of the appliance.

Signs this part needs replacing

  • Domestic hot water runs hot then cold, or never reaches the set temperature
  • Hot water temperature drifts away from the value set on the appliance control
  • The appliance fails to fire on a hot water demand despite the tap or outlet calling for it
  • Fault codes or lockouts relating to the DHW sensor or thermostat circuit appear on the display
  • Resistance readings at the thermostat fall outside the expected range when tested with a multimeter

Before you order

  • Confirm the appliance model and serial number against the compatibility list, as the same thermostat body is used across several Heatslave variants
  • Check the existing part number on the component being removed and cross-reference it with 1015223
  • Inspect the thermostat pocket and any sealing washer or O-ring at the same time, as these are disturbed during removal
