Baxi Immersion Heater 95606957

The 95606957 is an immersion heater supplied under the Baxi brand and used across Heatrae Sadia and Baxi Megalife Solar hot water cylinders. It screws into the cylinder boss and provides a direct electrical heat source, either as the primary means of heating the stored water or as a backup to the boiler-driven coil. The element and its associated thermostat assembly sit inside the cylinder, so the unit is exposed to the full stored water temperature and to any scale carried in the supply.

• No hot water from the cylinder when the immersion is switched on, even though the circuit is live.
• The immersion circuit breaker or RCD trips as soon as the heater is energised.
• The element is heavily scaled or corroded when inspected at the boss.
• Water weeping from the thread or around the head of the immersion.
• The cylinder reaches temperature erratically, or the water runs hot then cold, pointing to a failed thermostat rather than the element alone.

• Confirm the cylinder model and serial number against the compatibility list, as several Megalife Solar and Heatrae Sadia variants use different immersion assemblies.
• Check the existing immersion head and thread before removal so the replacement matches the cylinder boss.
• Inspect the sealing washer at the boss and renew it if it is compressed or perished.
