Winterizing Your Home

A home inspection will look at the systems that make up the building such as:

• Structural elements, foundation, framing etc
• Plumbing systems
• Roofing
• Electrical systems
• Cosmetic condition, paint, siding etc

Inside Your Home

• Have your furnace system serviced to ensure it’s working efficiently and not emitting carbon monoxide.
• Clean permanent furnace filters and replace paper or disposable filters.
• Replace the batteries in smoke and carbon monoxide detectors.
• If you have a wood stove or fireplace, have your chimney swept thoroughly. It should be cleaned before the soot build up reaches one-fourth inch thickness inside the chimney flue.
• Check your hot water heater for leaks and maintain proper temperature setting (120 degrees recommended by Department of Energy). On older water heaters with less insulation, for every 10 degrees Fahrenheit you lower the temperature, you save 6 percent of your water heating energy.
• Check the attic to see if insulation needs to be added or replaced. This is the most significant area of heat loss in many homes, so it is also important to see that it has proper ventilation. Inadequate ventilation could lead to premature deterioration of the insulation materials. You may also need to check insulation in exterior walls, crawl spaces and along foundation walls.
• Check all windows and doors for air leaks. Install storm windows and putty, caulk or add weather stripping as needed.
• Check basement and cellars for seal cracks or leaks in walls and floor.
• Make sure all vents are clean and operating properly.
• Clean and vacuum baseboard heaters, heating ducts and vents.
• Remove or winterize air conditioning units.

Outside Your Home

• Store or cover outdoor furniture, toys and grill.
• Purchase rock salt for melting snow and a shovel or snow blower if you don’t already have one. Make sure you have the right kind of gas and oil on hand for your snow blower in the case of an unexpected snowstorm.
• Caulk joints and minor cracks on exterior walls and siding.
• Look for deteriorating finishes. Minor problems can be patched to preserve the wood. Put bigger jobs, such as scraping and refinishing painted or stained areas, on the calendar for next spring or early summer.
• Drain and shut off sprinkler systems and other exterior water lines to avoid frozen and broken pipes. Leave all taps slightly open.
• Insulate exterior spigots and other pipes that are subject to freezing but can’t be drained or shut off.
• Rake and compost leaves and garden debris, or put out for yard-waste pickup.
• Clean storm drains, gutters and other drain pipes.
• Check the foundation for proper drainage. To do this, spray yard with a hose to see if water runs away from the house. A little shoveling to reshape the earth next to the house may make the water run away from the foundation.
• Make sure dirt or piles of wood don’t come into contact with or touch siding, inviting termites and carpenter ants into the house.
• Seal driveway and walkway cracks, if needed, before ground freezes regularly.
• Inspect the roof for loose, damaged or missing pieces.
• Check attic vent openings for nests or other blockages.

Apricus Evacuated Tube Solar Collector

Apricus Evacuated Tube Solar Collector
(Thermal solar heating)

The Apricus Solar Collector or Solar Water Heater is a device that absorbs thermal energy from the sun and converts it into usable heat. The heat is normally absorbed by water, or a freeze resistant water mix, which can then be used to supplement hot water heating, space heating and even space cooling via use of an absorption chiller or dessicant cooler technology.

Below are the key features of the Apricus Solar Collector design.

The operation of the solar collector is very simple.
1. Solar Absorption: Solar radiation is absorbed by the evacuated tubes and converted into heat.
2. Solar Heat Transfer: Heat pipes conduct the heat from within the solar tube up to the header.
3. Solar Energy Storage: Water is ciruclated through the header, via intermittent pump cycling. Each time the water circulates through the header the temperatures is raised by 5-10^oC / 9-18^oF. Throughout the day, the water in the storage tank is gradually heated.

• Concentrates heat evenly near the floor where people are located
• Eliminates cold drafts as well as noisy fans, furnaces and ductwork
• Ideal for allergy sufferers because it doesn’t circulate dirt, dust or other airborne pollutants throughout a home
• Concealed under the floor for a more aesthetically pleasing environment — eliminating the concern of blocking vents with furniture
• Easily integrates with alternative energy sources, including geothermal, solar, waste and biomass
• Can help a home earn LEED® points for reduced energy consumption
• Potentially saves up to 40% in energy costs
