Hydronic boilers are popular in North America, especially in the Roaring Fork and Vail Valley's. Hydronic boilers started in Northern Europe because of their efficiency. They are an alternative to forced air heating in many aspects. Advantage's of hydronic heating are the ability to zone areas and have multiple temperatures of heat. Zoning areas allows for better control of temperatures because similar spaces in a building are kept at different temperatures than others. Copper piping, although slightly more expensive to install will save money in the long run based on copper retaining heat for a longer period of time. After the boiler shuts down, heat will continue to be emitted because of this retained heat. The piping is also smaller than duct systems and is easily worked into smaller spaces so it can be disguised and help keep the natural beauty of a home. It may be beneficial to your health because it doesn't spread dust, mold, or toxins into your household like some forced-air heating systems. They may allow more humidity to be maintained in conditioned spaces. Hydronic boilers come in all shapes, sizes and configurations that serve a multitude of applications. Overall, hydronic boilers are an affordable option and may provide a more efficient system of heating.
