Good quality pressure jet range cookers are a delight to use, and many more times more economical than the more traditional Sleeve or wick burning variety.
For example in the summer and used on "demand" or "Heritage Grande" 4 oven range is using less than 1.5 litres of oil per day. This keeps the kettle on the go when needed, domestic hot water should the solar system not be up to speed etc etc.
Controllability is the watch word -- A good manufacture (and we will not sell a range cooker we have not used ourselves.) Such as "Heritage" (made in Cornwall) or "Vintage" (Made in Somerset) provide just this. Set 150 Degrees on the oven control thermostat--and that's what you have with in minutes--Finished cooking turn it down !! Brilliant. Save Oil and costs and no overly hot kitchen in the summer time.
Special Note:- These Appliances are available now for delivery in France and notably they burn French heating oil (35 sec) with no problems. Unlike other well known Range Cookers which use vaporizing burner technology and therefore normally need servicing every 6 weeks!!
