Oregon nursery warms to the sun for long-term heating 

An interesting story out of the Oregonian today about a greenhouse installing a solar  system that will be used heat water in a super-insulated 300,000 gallon tank that will stay warm for months at a time. (Yes, you read those numbers right.) The water, which will replace natural gas heat, will be circulated underground and be used to keep the plants at the Blooming Nursery warm and growing. The story says it will be Oregon’s largest application of solar thermal  energy. To read the full story go here.

The system is so immense and the tank so well-insulated that it will retain heat for months at a time. Dinsdale expects to use her existing natural gas heating system only as a backup. She’ll continue to use natural gas in two other large greenhouses.
