Air and Water Heat Pumps in Fredericton- GT, PS
An air-to-air heat pump (with electric element backup) was installed as part of the construction of this new home, in 2008. The owner proceeded to add a backup by using a water to refrigerant heat exchanger to improve the efficiency of the system. The addition draws water from their deep well, runs it through the heat pump and dumps the water into a shallow well, so as to recharge the aquifer, creating an open loop system. The water to refrigerant addition takes over for the air-to-air component when the temperature dips below 0 °C (32.0 °F). This temperature will be slowly raised, …
Solar Hot Water Collectors in Fredericton Firehall- SE
The water heating system was upgraded from an oil burner to a natural gas burner some years ago, and has since had the solar hot water system as a water preheat to the natural gas burner. The installation was fairly quick and easy, and works well. …
1.2 kW Photovoltaic System in Charter’s Settlement- SE
The owner’s experience with the system has been very positive. He installed the system himself with no problems, intending to have an off-grid office. The batteries were received from Eastern Battery Systems on sale. 12V lighting was installed as part of the system, while the rest runs off of a small (300 watt) pure sine wave inverter which runs a computer, printer, and other office appliances. A wood stove certified by the United States Environmental Protection Agency is used for heating. …
Solar Hot Water in Fredericton- SE
The system was installed in 1992, and has had several issues over its lifetime. In 1996, plastic piping (connecting the collectors with the heat exchanger) was replaced with ⅜″ copper piping, which is better able to withstand high temperatures. The pump was replaced in 1999, as it had worn out. Shortly after that, the glass on one of the collectors collapsed, which effectively shut down the system. It has not been fixed since. The owner hopes to have the system up and running soon, because when it did work, it seemed to work well. …
Passive Solar Home in Bristol- PS
This new, passive solar home is built with a South-Southwest orientation, which is best for collecting heat and light from the sun. This home has large, efficient windows (double pane, low e) gathering heat all day, which is trapped by this highly efficient house (lots of insulation and tight building envelope). This makes the home very comfortable, with it being hot inside on days of −30 °C (−22 °F) or lower. On cold days with no sun, a wood pellet stove provides backup heating. …
Solar Hot Water for Car Wash in Woodstock- SE
This car wash uses a large volume of hot water for serving roughly 20000 vehicles per year. This large solar thermal system was installed to aid in the production of hot water, and to offset the primary heating source — an oil furnace. …
Passive Solar & Masonry Heater in Bocabec- BE, PS
A number of features have been added to the house to make it more efficient, such as the use of strapping (to reduce thermal bridging), putting insulation on the exterior of the concrete foundation (so as to maximize thermal mass), and lots of insulation in the walls and ceiling. The house is also somewhat submerged in a hill, so as to provide extra protection from the elements. Local materials were used for constructing the house, such as local harvested trees cut at a local, water powered mill. Bricks for the masonry heater came from Lewiston, Maine, the closest source for …
Vegetable Oil Furnace in St. Andrews- BE
As a source of heat to meet requirements during the colder months, a furnace was installed which runs on waste vegetable oil. The owner had previous experience using veggie oil, as he has run his diesel vehicles on waste veggie oil for many years. The furnace is very efficient (90% +) and works well using the veggie oil. To view this home’s other feature, please visit the following link: Passive Solar, St. Andrews …
Passive Solar in St. Andrews- PS
A number of features have been added to the house to make it more efficient, such as the use of strapping (to reduce thermal bridging), insulating foil as a vapour barrier, and lots of insulation in the walls and ceiling. Local materials were used for constructing the house, and no trees were cut down in order to accommodate its construction. …
Solar Hot Air and Water in Elmwood- SE
This four bedroom, three level home has great southern exposure. The owner has experience in the construction field and has also taken training in performing solar hot water installations. He decided that he could get great value from installing two solar thermal technologies – a very efficient solar hot water system from Enerworks and two Solar Sheets to provide space heating, one on the main floor and one on the upstairs level. …
