Economy 7 Immersion Heater Element

I have an economy 7 water tank fitted with two immersion heaters one at the bottom of the tank and one about halfway up.

Economy 7 immersion heater element. Hi we have an immersion heater that is supposed to run on economy 7 electricity and heat up our water through the night. One morning i woke up to find there was no hot water and since then the economy 7 mode has not worked. Countdown boost display shows boost time remaining. Designed for use with economy 7 off peak rate overnight electricity plans.

Immersion heaters are electric heating elements that are found in water cylinders to heat water. If an element in an immersion starts to heat theres no noise. Suitable for use with single dual or twin element immersion heaters. Pre programmed automatic boost and three on demand options 30 minutes 1 2 hours.

After 15 years they were replaced as they had started to heat inefficiently. I have an economy 7 immersion heater setup with a horstmann economy 7 quartz control unit. The benefit of an immersion heater element within your heating system is that it means even the boiler fails you should still be able to get hot water. I replaced them with new elements.

Economy 7 water not heating overnight the entire water heating unit has had both elements boost and e7 replaced only 3 months ago but in the last 48 hours the e7 has stopped working it is not coming on at night when the radiators come on. A typical immersion heater how it works and how to test it. The boost mode still works. The off peak element was placed on just over 50.

Interchangeable with sangamo and horstmann economy 7 units. I have checked the fuse seems ok. The lower heater is wired to a circuit which is only live during cheap rate and the upper is wired on a normal circuit which is live all the time. They act like a kettle to heat the surrounding water in the cylinder.

I have an economy 7 boiler which has two temperature controlled heating elements.
