I know this is an old post and amdisil has probably made his choice by now but, I thought I'd share this story
About 8 years ago, we were updating our kitchen and I did some research into residential cooking equipment.
My first thought was the Thermador Star Burner. It seemed very efficient for a home range.
When I visited the appliance store and discussed my cooking style and needs, he suggested that I may not be happy with Thermador (which he sells).
He suggested that I visit 2 different distributors and actually "cook" on the cooktops. Imagine that!
I went to the first distributor with my ingredients and my cookware and tested Thermador and 5 Star.
The first test was boiling water.
Same pot, cold tap water - Thermador, had to put the lid on the pot to get a boil in 9 minutes
5 Star - 4 minutes
To be fair, Thermador was sealed burners and 5 Star was open burners
Thermador was rated a 15K BTU and actually put out 12K
5 Star was rated at 18K BTU and put out 18K.
I went to the second distributor and tested Wolf
Water boiled in 5 minutes
Burners are semi-sealed and rated at 18K put out about 17K
But it was the double convection oven that sealed the deal.
Pre-heated to 550F Convection Bake with an integrated baking stone option
Made a pizza and slid it in.
When I went back to the oven in 6 minutes to turn the pizza around (to brown the other side), it was done perfectly!
I am now, and have been for 8 years, the proud cook in a Wolf kitchen
The morale of this story is:
Go cook on the equipment you are planning to buy.
You wouldn't buy a car without a test drive and a well outfitted kitchen will cost as much as a small car!
