Tim, this is Toby. You brought a boiler to me this past fall in Grayling, Michigan. I’ve talked to you a few times about questions, concerns, issues I’ve had learning the machine. I know you talk to a million people but I just wanted to say that the machine is working amazingly and I couldn’t be happier with its performance. My house is toasty. My family is happy. I haven’t used an ounce of propane in months. It’s been awesome. thanks again for your continued support and for this great machine!!
