thats assuming the pump runs constantly. ill bet it doesnt.

No. Not at all. Could be a half to a third of an hour normally in total. If the rayburns really hot it will run more.
Mine like books. They'll cope without a screen for a few hours!Until the kids are older and in school and all they want is to sit infront of a screen like vegetables
The store is gravity fed from the Rayburn. It needs to circulate from there round the rads without replumbing all of them!
One of my colleagues has had multiple long power-cuts over the last few days - there's a fault somewhere underground in a min cable they are struggling to find.
However, they recently bought an electric car - so they run an extension lead out to the car and can then plug up to 4kW of stuff into the other end. Drive car to work, plug in to one of our chargers during the day.
So simply buy a battery car

If they are standard car batteries you will need to redo your calculations.
Once they get below 10v they are pretty much done, keep going and you'll wreck the batteries.
To provide a long steady supply you need leisure batteries, designed to be discharged to much lower voltages.

Some standard car, but there are two leisure batteries in the shed as well (three if I take the one out of the caravan!)

and all it takes is buying extra radiators and plumbing them into the gravity fed system these can be set for open or close when needed by gate valves but these valves will need replacing as they will seize up without usage and wear and tear or by opening and closing them,
but most dont want to fit them they want simple central heating and both ways are simple
if a power cut does happen you have 3 rads that are still using a gravity fed system and not reliant on the power otherwise its buy a gen and use that for power of the pump and for the heating system a system that can be plugged in via extensions to connect power for pumps/zone valves and heat stat otherwise that system wont run correctly as its power based
the only warning i wall say is dont touch those rads they will be burn hot to the touch as it happens with gravity fed fired from stove heater fired all day long but gives high heat output from them
do not use plastic either the heat in the pipes will also be very red hot
But Gaz, how is this more simple than buying an inverter, sticking a plug on some wires and using batteries and rads I have?!
I understand the concept as my parents house had it for the old Aga anthracite boiler. It was useless though as the rads were not in places we wanted hot...

solar panels and invertor + batterys is the same as a generator both need certain things
one depends on solar the other on gas or fuel
a note has to be said that pumps and zone valves need power so if you have both in your system factor that power difference for those on other systems pumps/zone valves and wall stats need to be considered they maybe low power but they do use it factor in zone valves and pumps and your using more power than you think its worth checking your system
vs piping in rads the issue stands at wheres best for core heating of the property though in large houses its in the hallway as you can heat rooms up from the staircase and hallways compared to the old method of chimneys though you could use radiators and tubing to heat rooms up via air heating
freezer fridge would be my preference with lighting and core heating via the stove via gravity system
Gaz, you might need to read from the start. This was 'how do I circulate heat from my Rayburn all around my house using the existing rads in the event of a powercut, can a car battery do it?'
No solar, no generators, no replumbing, just a simple battery from the shed and a 100£ inverter.

I live in the middle of the sticks so thought this would be a regular issue too, have the aga for cooking, the log burner for heat but would need the boiler for all of the heating and hot water so just put it on a plug rather than a spur, then I chuck an extension lead on it to the generator in the garden. Since then though I had solar and batteries fitted, the inverter has an EPS output on it but as it's in an outbuilding it's not been wired into the house supply with a change over switch etc. We had a long power supply in the summer when some plonker put one of those fence post augers through the main cable in the village, so I isolated my main incomer and wired the EPS on the inverter to a socket in the outbuilding, worked a treat and kept me going into the next day no problem. Took it all out for turning the mains back on though obviously.

I've a standalone changeover switch buried deep in the garage somewhere. Recently I've been mulling how you would incorporate a changeover switch within an actual cu for a super neat solution:
I presume there are just links in that bottom bus bar?

Yes by default mains is connected to bus bar. If you throw the switch the other way it disconnects the mains inputs and connects the generator inputs.
I ran a secondary mains isolates 240 volt set of four double gang switched three pin sockets into the bungalow and have an external box with 30 or so get of fly lead to get the 3kva pure sine genny hooked up . The heating has one of these alternative sockets adjacent to the changed to switched plate from hard wired socket . If a power cut occurs it's torch out, unplug the heating& replug to stand by socket . Open the outside box take the fly lead to the genny and use auto start then once back inside switch on the heating socket & the auto start heating takes place .
A few years ago about the begging of August (?) I had cause to be really thankful for putting the alternative sockets in as I'd just come out of hospital with a new knee joint and a nasty spinal spasm.
I was bed bound for 4 weeks at home , some guy big on something took out four power poles and ripped out 20 m or so of underground cable when he used his car to fatally take out the power . The first cut lasted for 9 hrs till his body was extracted and a temp board genny was found & shipped in . For the next six days we had all manner of power cuts till everything had been renewed and tested .
