## Description

Immersion Heater. Backersafe Immersion Heaters are manufactured to the latest Legislation of BSEN60335-2-73. Two specific clauses within this specification are aimed at eliminating the risk of boiling water. The most significant requirement is that the Immersion Heater be isolated from the mains supply, should the primary thermostat fail with the contacts closed, which would allow the water to reach a temperature in excess of 85Â°C."

Review: Well packaged and not damaged - It is exactly what the description says. Very good and well packed
Review: Reliable brand. Top product. - Does exactly what it's there for. I've had it in two years now and not had any issues so far! I had to use high temp resistant silicone around the threads because PTFE tape wasn't doing a very good job, but I blame that on the old tanks threads rather than the products threads. Highly recommended product.
