I bought about a month ago to replace an old gas range, max BTU 11000-12000. It would take 15+ minutes just to boil a pot of water. Now it's like 6-7 minutes! With all this newfound range heat, I've had to adjust accordingly, but I'm loving it! And I love the oven and how fast it heats up. And also the wifi features! I'm really glad I bought this range!
