"Theoretically, it just seems smarter to have heat on top, rather than below the subfloor. The people involved in my new home project did a great job. I installed a boiler with a sensor that assesses the exterior temperature, allowing us to really control the fuel costs. I am convinced the savings offset the cost of the Warmboard system. For example, our winter weather can drop to 20 degrees below zero, and in our previous home fuel heating with propane was costing us six to seven thousand dollars a year, this year it cost only one thousand dollars. That is a huge savings! The design documents Warmboard supplied were excellent, and we have 11 zones in our home. Also, as a builder I recognize that Warmboard reduces labor costs, and since you know where the tubing is, repairs are simple. The Warmboard system just makes sense!"
