Hello, I work for WarmlyYour Radiant Heating. We offer complimentary design and installation plans. If you have a sketch with dimensions that you can send me at gjazwinski@warmlyyours.com we can get you an exact design and quote by Monday.

I can give you a rough idea now. We recommend that you do not heat wall to wall, and you cannot heat under any cabinets or other permanent fixtures. That usually equates to about 70% of the total square footage ends up being heated. Based on covering 475 square feet, the cost for the TempZone floor warming would be about $3,000.

When WarmlyYours floor heating systems are installed on a concrete slab, we strongly recommend adding a layer of insulation prior to installing the system. While our systems provide up to 25% more heating power per square foot than many of our competitors, the slab will always act as a "heat sink." Some of the heat that would otherwise be transferred to the flooring surface will remain in the slab, causing the floor’s surface temperature to be considerably lower. This is true with any floor warming system. When installed on top of a concrete slab without insulation, it is generally accepted that a radiant floor heating system will take the chill away from the floor and provide a small amount of warmth. Adding insulation on top of the slab and beneath any floor heating system will allow a greater percentage of the heat generated to transfer to the flooring surface. This results in greater efficiency and therefore faster warm up times, higher expected surface temperatures and lower energy usage. The floor will have the capacity to warm to a comfortable temperature, and in some cases can be employed as the primary heat source for that room. The recommended types of insulation are natural cork, insulated tile backer boards and insulated underlayment, such as CeraZorb synthetic cork.

CeraZorb to cover the entire 675 square feet would be about $1,600.
