An R-2000 home! This self-installed solar hot water system (using propylene glycol) provides both domestic hot water and space heating through an in-floor heating system in the garage and house. The owner had originally considered installing oil to provide this heat, however, after looking at installation costs and the ongoing rising cost of oil, solar thermal was considered instead. They are very happy with their choice to go solar.
The Open Sky Co-operative in Middle Sackville, N.B., is housed on a 4.5 hectare (11 acre) farm and home dating from the 18th century. Heating an older home can be a challenge, and so the Co-operative undertook renovations to improve energy efficiency and to incorporate geothermal & solar energy on the farm.
