I have a 2 door, oil fired one – it is the only cooker in the house. We moved in about a year ago now.
We had a bit of a learning curve with it, thought about redoing the kitchen to accommodate a conventional oven but it has never happened.
The hot plates on mine are hot enough to stir fry on, you start to learn where different heat zones are and move pans around to suit. Top oven makes fantastic roasts, bottom oven is superb for slow cooking (and did our Christmas Cake in it this year!). The kitchen is lovely and warm all the time, and the heat rises and heats upstairs pretty well too.
I turned it off for a bit in summer and used the BBQ outside instead! I think when we re-do the kitchen properly we will perhaps get a double hob or something put in for summer use, but my wife has declared that should we move (or just redo that kitchen) she wants a 3 oven version as non-negotiable now 😉
