Or perhaps this? clicky Then I can charge up a couple of batterys and have two on standby? Would the oil fired boiler work on one of these?
Maybe, then again perhaps not. It's impossible to say without testing or speaking to the manufacturer. If you want to be assured that the boiler will function correctly then you will need a pure sine wave inverter. If you take a look on eBay then you'll see there's plenty to choose from on there right now.
However, as the batteries and inverter are going to set you back at least a few hundred, I can't understand why people on this forum are trying to dissuade you from buying a generator instead. The price would be about the same, you'll not have to waste energy all year round keeping batteries on trickle charge, there will be no batteries to replace in X years time, you'll get more watts for your money, and, unlike batteries, when the tank runs empty you can just refill it! What's more, models like the Honda eu10i are extremely portable and relatively quiet.
