Hiring is an option, one I hadn’t considered honestly. However like I mentioned before there’s more to it than plug and go. Because this will be heating something other than a single family dwelling, the oil tank must be bunded as standard along with proper location and any required fire protection. If your house oil tank is bunded and complies to regs you could run a second supply from tank, again this must comply and if you’ve only got a small tank running two burners then refilling Will be more frequent. Also the flue needs installing and you can see the outlet from the unit in picture.
