Roy Collver, Mechanical Systems 2000 Inc., is optimistic that the best of both systems can be wedded successfully in residential applications. As living proof, this manufacturer's rep. from Calgary, Alberta, has designed such a system for his own home. He even has a heated fish pond, a heated driveway and a heated backyard. But he also admits he's unusual in that regard?
For now, Collver said he realizes there are some drawbacks that keep many contractors from delving further into hydronics. On the upside, "radiant floors have energized the hydronics business over the last few years." However, many builders still are reluctant to offer hydronics heating systems in new homes because of cost, "although they will offer granite countertops." Collver spoke at a session on combining hydronic and hvac systems at the Canadian Mechanicals Exposition (CMX) in Toronto.
