Solar Space Heating
The Basics:
New construction is the preferred application. Renovations or retrofit installations are possible but they are far more difficult and expensive.
Attention to high quality building insulation standards are key to the success and ultimate payback of the system.
Yearround solar heating is feasible but weather fluctuations affect everything. The dead of winter requires a back-up heater or boiler. The shoulder seasons perform very well and there will be an excess of energy in the summer. Got a swimming pool? Perfect.
The Pieces:
The lower the delivery temperatures you can supply, the more solar contribution you can expect. This concept is best suited for radiant floor heating systems.
More solar collectors is not necessarily better. A proper design, including drainback technology, will bring you closer to energy independence.
Strategic control design is critical to uninterrupted comfort from your delivery system. The system should look for stored solar energy first and then switch to a boiler back-up when necessary.
The Incentives:
State energy tax credits not to exceed $1,500.00 are available to qualifying solar space heating and combi systems.
The federal tax credit has no cap is based on 30% of the total cost of the system.
