Range Tribune Question

[Reefs]

Hi all,

I’m looking for some advice on a Range Tribune HE.

it is fed from a system boiler, and I didn’t believe the immersion heater was in use.

Since I have been provided better graphs from my smart meter I can see both gas an electric spiking when the cylinder heats up.

I appear to be spending more money on electric than gas to heat the water.

I don’t have any switches, and from a colleague who has a similar setup, he has his immersion turned off, and can turn it on as a backup.

I don’t have this option, should I?

If you have a immersion that’s wired up it must have a isolation switch

There is a plastic cover, with part numbers, but no external cable, or isolation Which led to me believe it wasn’t in use.

there is a very odd electrical correlation with the gas and the heating timers in the house.

An immersion element draws 3kW and will run for 2 hours to heat 120 litres of water from 10C to 60C. 6kWh consumed.

Rough figures, of course, and less if you start from a warmish tank.

You seeing a draw of 3kW on your "spike"?

The correlation is uncanny. I’m intrigued to the point I want to find out why the electricity follows the gas.

Then start by giving figures in m3/h for gas and kWh (and kW)for leccy.

Or post pictures of your cylinder and boiler.

Cylinder pictures to show any cabling connections.

Thanks, I’ll post the pics. What tools would you use to get spontaneous readings? I don’t think I have enough detail on the smart meter to get the figures for a specific time period.

Well, that immersion certainly is not connected.

I know nothing about "smart" meters; can yours be tweaked to give you readings other than in pounds, shillings and pence?

 

[Reefs]

Thanks, I didn’t think it was.

the meter will give you some overall stats, kWh for the day for example, but not for a specific point in time.

I want to find out why the electricity follows the gas.

Change the times of the gas to something else (such as several hours earlier), and see if the electricity moves with it.

It almost certainly won't - the peaks of electricity use are exactly when they would be expected, as in morning when people get up, and evening when people return from work and switch everything on.

 

[Reefs]

I might just turn the boiler off for a day

Your boiler and pump both use electricity when running as well as the boiler using gas.
So when it fires up both will go up on your smart meter.
