help Powering UK gas combi boiler electronics with portable battery power station
I have a Logic ESP1 35 gas combi boiler, which is standard hardwired into a 6A breaker in the UK consumer unit through a basic isolating fused switch that I can turn off.
My hope was that I could replace this switch with a socket-switch, and put a 3-pin plug on the boiler cable. That way, in the event of power cut, I could unplug the boiler and plug it into an Anker S2000 power bank for some temporary heating and hot water.
I have seen many people on Reddit discussing this option (using a petrol generator instead of batter power station), and the standard response seems to be "Sure!", "Go ahead", "Great idea!".
However, nickymoo raised a good point here.
I believe my boiler has a flame-detection circuit (it is referenced as a failure mode in the manual), which requires some kind of earth-neutral bond. I am trying to understand whether running this boiler from a S2000 power bank will A) cause any safety issues with the earth, and B) prevent the boiler from igniting because of the flame detection circuit failing.
I am not looking for someone to tell me go ahead and do it, as I am aware this requires professional opinions. I have reached out to Anker support for clarification of the earth/neutral behaviour when power is lost and the unit moves to battery, and I will be having a chat with some electricians this week. But looking to gather a few more opinions if possible. I would like to hear form anyone who might have encountered this issue before.
