We Design, Install and Maintain In-Floor Radiant Heat Systems

A radiant floor is the most perfect heating system for comfort, aesthetics and energy-efficiency, and ideal for all types of floors. The comfort and efficiency come from the fact that in-floor heating warms objects, not the air.

Over the years we have built a loyal and discerning clientele in Seattle and around the Puget Sound area. We work with homeowners to evaluate the heating requirements of a structure room-by-room, and take into account your individual needs and lifestyle.

Our goal is to provide Seattle homeowners with a lifetime of trouble-free operation combined with low energy consumption.

Our radiant systems employ hydronic heating. Hydronic refers to the use of hot water as the heating medium. It is the heating system of choice throughout most of Europe, where it is found in 95% of homes and buildings. Most of our systems utilize European techniques and technology. You will appreciate the Old World craftsmanship and state-of-the-art technology embodied in these systems and products.

If you'd like to learn more about radiant heat, come see our showroom. Or just give us a call. Our expert team is ready to help.
