What it is

The Ideal 176749 is a 3kW immersion heater with a 1 3/4 inch BSP threaded connection. It screws into the cylinder boss on Ideal thermal store units and provides direct electric heating of the stored water, either as the primary heat source or as a backup to the main system. It is listed for the Ideal Thermostore range and Ideal Commercial appliances.

Signs this part needs replacing

  • No hot water from the cylinder when the immersion is switched on and the circuit is live
  • The element trips the MCB or RCD when energised
  • Continuity or resistance test across the element shows an open circuit
  • Scale build-up, corrosion or a weeping joint at the cylinder boss
  • Water temperature is inconsistent, or the immersion cuts out earlier than expected

Before you order

  • Confirm the cylinder model and the boss thread size on the appliance data plate; a 1 3/4 inch BSP fitting is not interchangeable with other boss sizes.
  • Check the part number stamped or labelled on the existing immersion heater against 176749.
  • Cross-reference the alternative number 1783126 when checking older stock or documentation.
  • Fit a new sealing washer at the cylinder boss during replacement and check the electrical supply rating matches the 3kW element.
