Eddi not heating water long - config required?

OO7FITZY

You could be right

Cyslinder is 20 years old I think and connected to an Eddi hot water diverter that's on most days so prob needs replacing

thx for feedback!

Also, the temp stat is at max, probably lead to shorter life span of immersion element (just a hunch)

slave1

afterthought, is it working at all? could just need temp stat replacing

OO7FITZY

Not working

drawing zero power

I'd try temp stat replacement first to avoid hefty immersion replacement, around €12-€15 from any electrical supplier

It should be under the blue cover on those thermostats.

So in my case, I had my solar installer call out yesterday. Turns out it was the thermostat in the immersion that was goosed! A simple and cheap replacement, seems to be fine now.

Just had the thermostat replaced and still not working

Eddi not showing any Kw going to Tank 1

Used voltmeter at contact points and can see Eddi is not sending power to cylinder

So it seems to be an Eddi problem now

I wonder if the firmware update caused an issue? It boosted once after the udpate but never since and now the termostat is new then problem points back to Eddi

thoughts?

If you put the eddi to bypass, is the immersion heating?

It's on the switch at the bottom

OO7FITZY

thx for advice

Moved the switch to bypass and screen on Eddi turns off but blue light on tank 1 is on

There is now hot water coming from the cylinder

App still showing no Kw to cylinder prob because the Eddi hub is off

So back to something wrong with Eddi / Eddi settings?

Bypass, bypasses the eddi and heats directly.

If you hit boost on the eddi, nothing happens?

If that's the case, contact myenergi

Deffo myenergi, they are very easy to talk to and have their own fitters in Ireland now

OO7FITZY

Thx again

contacted installer yesterday and they requested the serial number of the Eddi and will contact myenergi to help resolve

one last question - where does the eddi pull the power from on the bypass setting? Is it the panels or the battery or both or the grid?

slave1

on bypass the EDDI is dead so power will pull on demand, so if at night from the grid, if noon from surplus PV with grid top up as necessary

Bypass takes the eddi out of the loop entirely, power "bypasses" the eddi, think of it like an immersion switch.

In normal mode, boost does nothing?
