Economy 7 Immersion Heater Timer

[drurydd1]

Hi All,

I have a very strange problem to solve.

We are on economy 7 metering with 2 CU, 1 for appliances/lights and 1 for our heaters and the immersion heater. The immersion heater has its own 16amp fuse on the CU.

The problem we have is the immersion heater switches on about 3pm and goes off around 5pm we have looked everywhere and cannot seem to find any sort of timer switch. Is one of the meters controlling when the immersion heater comes on and off?

We are going to have another look for some sort of timer at the weekend and I was looking for any information to help me understand how this could be happening.

Sorry for the lack of information/detail

Immersion is controlled by economy meter so should come on when economy 7 kicks in What is Economy 7?

Sounds like the timing of your economy seven is out, I’ve come across this before. It thinks it starts at 3pm, by 5pm I expect the cylinder is hot so the immersion goes off again.

Observe which tariff meter is running when this immersion comes on at 3pm.
It is then for you to decide wether to tell the electric company and get the timing correct OR wether the way it is is beneficial to you

Do the heaters come on at the same time?

Are you sure its not turning on and turning off via the thermostat which is what it’s supposed to do .
