Hydro-Air Heat, Partially Solar-fed Indirect Domestic Hot Water, and In-Floor Radiant

Bob talks with Tim Cutler from TJ's Plumbing and Heating about the Viessmann boiler. The boiler is heating the domestic hot water, the radiant floor heating, and the hydro-air heating system. The hydro-air system has an air handler with a hot water coil. Warm air is dispersed throughout the building using this hydro-air system, which heats the existing, older portion of the house. Showers and hot water will be fed by a 79 gallon indirect, dual-coil, domestic hot-water tank. The bottom coil is fed by the solar heating system, which has 30 Viessmann evacuated tubes on the roof. The tubes have alcohol within them which has a low boiling point. When the alcohol in the tubes boils, it transfers the BTUs to a bulb, which transfers the heat to the lower coil for domestic hot water. A concrete cutter came in to cut an opening in the basement between the old portion of the home and the new addition. Bob talks with Bill Sloan from Viega North America about the radiant slab heating in the new addition. The radiant heating system uses PEX tubing. Viega manufactures the manifolds for this tubing and the copper tubing used to transfer hot water to the PEX tubing. ProPress joints that do not require any soldering are used for this sytem.
