I have an aga: A 4 oven traditional gas aga.
I LOVE it. While my gas bill is pretty high (I also have gas central heating and boiler for hot water; my house is a very large 300 year old stone farm house, with 22 radiatiors, and 4 bath rooms) my electricity bill is pretty low.
I have no need for a tumble dryer or electric kettle. I have a toaster but often use the aga toaster.
I dont use an air fryer or a slow cooker, and for over a year i managed without a microwave (but have got one now, for ease of making hot chocolate without a sauce pan).
I live high up in the middle of the countryside in Yorkshire. Its gets COLD up here (really cold) and we have more than our fair share of snow, and my 300 year old house is not insulated, and has wooden windows (because its listed) and gets very cold very quickly
The aga keeps my kitchen warm all the time (and my wood burning stove in the sitting room ensures my whole downstairs is toasty, even when my upstairs is not!)
I like to cook from scratch so I get value for money for cooking.
I make all my own stocks (over night in the simmering oven)
and bake my own bread (and always have the warm conditions for my starter to rise and my dough to prove)
On days I work and leave at 7.30am i often plonk a les cruset dish (prepared 1 or 2 days before) into the simmering oven (straight from the fridge), and then have a casserole / bolognese / chilli / stew ready at tea time.
I make all my own soups, cakes / biscuits and cook all dinners from scratch.
I dont even have to think about turning an oven on, its always ready
You cant beat an aga roast, and the ability to get food ready then leave in the warming oven until you are ready
My aga dries a whole load of washing most nights (but not in the summer when i use my washing line)
My aga is 22 years old, almost as new, serviced every year (aka hoovered out and given a new thermocouple) and reliable.
I absolutely love it. (mine does not heat water, only the kitchen)
Yes my gas bill is high (also blame my 22 central heating and 2 teenage girls who have long showers) but my electricity bill is very cheap in comparison.
Its also great at drying football boots / trainers / hats and gloves / school books that water bottles leak on, and also I use it as a draining board to properly dry cake tins, plastic tubs and kids water bottle etc.
Dont get rid of your aga without trying it. You will probably learn to love it.
