Playing with heating option atm and currently for whatever reasons keeping oil is looking best. One thing is new oil boiler, second option is oil stove e.g. something similar to (but not) https://www.eurostove.co.uk/harmony-h11-oil-stove
I know aga type stove need to be on 24 hrs a day and this says designed to run 24 hrs a day but I can't see what is wrong with running it less as its not the same mass a aga type thing. What is the disadvantage of a stove like this vs a boiler? Seem like the good point of this is that you get heat from stove and to central heating system, the heat is not lost in a lean to as it is for us where our current boiler is situated. We are happy with immersion and planned solar for summer hot water.
What's going to heat the rest of your house ? That's 2-5 kw....
Must have linked to the won't one. It's 9kw the one I had. In addition we have a wood burner with back boiler.
I guess the question is what do you want to achieve? Constant heat source + central heating/hot water, or just central heating?
If the former, maybe an oil stove. If the latter, then new boiler (and you shouldn't get any 'waste heat' from a new, decently insulated one).
FWIW we replaced an oil Rayburn with an external oil boiler last year. The Rayburn was only ever used for central heating/ho****er so only kicked in with the heating timer, it wasn't on all the time. It was never used for cooking, so was effectively just a massive, noisy, inefficient sideboard in the kitchen. The new boiler has used about half as much oil so far this winter as we used to the same point last winter (some of this is down to having the heating on less and at a lower temp, but not all of it).
I think you would be nuts to go with an old fashioned solution unless you live in a 2 room house and like living in a sauna in the summer?
Are you looking at a stove as in fire place, or stove as in cooking?
Either way I would just get a modern decent oil boiler which is 90+ efficient where as the oil stove linked is 74% efficient.
I'd like to run things as I currently do. Primary heat source is wood burner with back boiler but I have a switch and some valves to switch (including some safety interlocks) everything over to oil when I don't have time / ill / away. I was set on new boiler but came across that stove (or mor specifically a 9kw version) and thought, hmm seems like I might be able to flick that on and off as needed.

You'd be losing far more heat up the chimney with that stove (like over 1/4 of what you're paying for!) than you'd ever lose from having the boiler outside.
oops
