This special episode is all about making your home more energy-efficient. Plumbing and heating expert Richard Trethewey heads to Atlanta where he helps a homeowner install an instantaneous water heater to save on rising fuel costs. Then, up in the loft, landscaping contractor Roger Cook shows how proper planting of deciduous and evergreen trees can help reduce the costs of heating and cooling your house. Then, general contractor Tom Silva helps a pair of homeowners insulate the walls of their antique Victorian using blown-in cellulose insulation. Back in the loft, Tom demonstrates how to add additional fiberglass insulation to an attic.
Installing an instantaneous water heater
Richard visits a homeowner in Atlanta whose natural gas bills have increased dramatically in recent months. Richard suggests installing an instantaneous water heater. This type of unit does not have a storage tank and only burns gas when hot water is needed. Richard, with the help of a local contractor, begins the installation by determining where to locate the unit. This type of water heater is designed to mount on an exterior wall and vent combustion gases directly to the outside. Once the location is determined, the crew cuts a hole in the wall for the vent pipe. The unit is then bolted to the wall and the vent is connected. The crew then runs new gas and water pipes to the unit. Finally, the electrical connections are made and the installation is complete.Where to Find It

Roger shows Kevin how planting certain types of trees around a house can result in lower heating and cooling costs. Roger recommends planting a screen of evergreens on the north side of a house to prevent cold, winter winds from blowing against it. On the south side of the house, Roger recommends planting trees that will block the sun during the summer months and lose their leaves in the fall, allowing sunlight to warm the house in winter.Where to Find It

Tom helps a pair of homeowners who are worried about rising fuel costs and want to insulate the walls of their 1870 Mansard Victorian using blown-in cellulose. Tom begins by locating the studs inside an exterior wall and drills two holes in the center of a stud bay. One hole is about halfway up the wall and the other is near the top. These holes will accept a hose that is connected to an insulation-blowing machine. Tom inserts the hose into the lower hole and turns on the machine. After a few seconds of operation the machine starts to whine, indicating that the lower part of the stud bay is fully insulated. Tom then plugs the lower hole and inserts the hose into the upper hole. He then fills the upper part of the stud bay with cellulose using the same method. The process is repeated for each of the remaining stud bays.Where to Find It
