    I have a stove with a back boiler and in the case of a power outage I could use this to heat the house but I would need something like an inverter to power the small circulation pump .Often seen them in halfords and aldi but what size voltage would I need ,could run it off the car ,Wondering also would it be straight forward to fix up oil boiler to an inverter like at the moment it is wired to switch and has a seperate circulating pump

    I have an old APC SmartUPS that I pulled from a skip (new batteries) running mine.

    Tis hard to know what size inverter to get because inverters struggle bigtime with the inductive load of starting a motor. You'd be safe enough with 600-1000w pure sine unless it's a crap Chinese brand usually. This is despite the circulation pump probably being less than 100w.

    Don't run it off the car if you can avoid it, very easy to render the car unstartable or do damage to the batteries. Get a few scrap batteries if you're stuck or else "leisure" batteries that are designed for deep cycle usage

    I would get a inverter generator and plug in your heating system off that.
