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.

" OK Tim Cutler's with us now from TJ's plumbing and we're listening to the Viessmann. We've got three different kind of -- good things happening here right yes can you take us through it I can't -- Viessmann. Boiler which is heating our domestic hot water. It's also heating our radiant heating system and it's running our Hydro air heating plant here all right the Hydro air system is a the air handler with a hot water coil inside it right so the water gets heated by the boiler sent through the coil and then sends warm air out through the building. -- and that in the and that primarily is for the existing older part of the house right exactly yeah exactly and then what about domestic hot water needs for the showers in the kitchen et cetera. The child is in the kitchen get Fed by a 79 gallon indirect domestic hot water dual coil tank. The bottom coil gets Fed by our solar system which has. Viessmann evacuated tubes how many they're thirty on the roof. This is a copper fin -- can actually see it there you have here. What happens is it has alcohol inside this it has a very low boiling point right. When we boil it transfers to be too used to this fall and we pick it up and send it through this lower coil which heats our domestic hot water -- okay. And then on the other side of the room we're gonna talk to your colleague about the the tax -- exactly. All right -- him. Then going from the old part of the basement to the new addition what we did was we had a concrete cutter -- to provide this opening at over here bill slowness here from VA got. Now the heating in the new addition is actually up."

" In the slab right yes this -- front office in this fire return pipes from the slab and these are all pex these are all pex tubing right and then. Begin as manufacturing. The the manifold yes yes. And the this caught this caucus system there also which is the pro press system. Which is both your supply and return pipes you can fill a hot water. Going out then you can -- a return pipes returning move off right exactly. Oh yeah you totally can. Now what kind of joints are all of these. Is a -- press down spot progress pro press with a proper system that's been over in Europe for over 25 years and it doesn't require any soldering no sun and no flocks have you no mention this I know. This is layout pro press setting. Basically you can press from half to four inch KL or -- copper. Soft copper from have to into a corner and then there is like a black. Something in the era that is that he could be -- sealing element commonly referred to as they're pouring here. Okay. Excellent so this -- right this is this going to -- so cold in here thanks. Thank you."

Boiler Pipes and a In-Floor Radiant Heat in Bathroom

Bob meets with the plumber to look at the air handler and then goes upstairs to check out a bathroom floor heated with radiant heat.

Running HVAC Ductwork in a New Colonial

Bob meets with Peter Merianos and the crew from Coastal Heating and Air Conditioning who are fabricating the AC ductwork on site. With the Kenmore air handler already installed in the attic, the crew begins assembling the ductwork using five-foot lengths of pre-crimped sheet-metal ducting as the basic material. The sections snap together and are secured with sheet-metal screws and foil tape. To add a new line off the main trunk, the crew cuts a hole into the the trunk with a special tool. A starting collar from which the new line will extend is then inserted into the hole. The ductwork is insulated using vinyl wrap, which is a one and a half-inch vinyl-coated fiberglass blanket.

HVAC System for the Home Addition

Bob meets with Mark, a heating, ventilating, and air conditioning mechanic. Bob and Mark have an in-depth discussion on why a homeowner had to add an air-conditioning unit to an existing air-conditioning unit. The new space added onto the residence was too large for the old unit to cool, so a new 1-1/2 ton unit had to be added. They also describe how the particular unit cools the home and the major components of the unit.

Air Conditioning Condenser Install

Kevin Callahan from Sears joins Bob to talk about the new Kenmore air conditioning condensers that will be installed. The condensers are Energy Star rated and have a life expectancy of over 15 years. Callahan explains the unit's internal components, starting with the copper coils that contain the unit's refrigerant. Heat is transferred out through the fins around the inside edge. These condensers are 3 1/2 ton units (one ton = 12,000 BTU's). Callahan also talks about the SEER rating, the Seasonal Energy Efficient Ratio, which is the measurement of the product's energy efficiency and helps determine its Energy Star rating.
