Solar heating systems can be utilized to supplement radiant heating systems, providing a renewable energy solution that provides radiant comfort. Radiant slabs provide for the most effective use of stored solar energy and increase the total efficiency of the system. This approach provides solar-heated domestic hot water spring through fall and minimizes propane use for space heating, especially in the shoulder seasons in Maine.

In addition to leading our local contractor efforts, our founder Vaughan Woodruff provides consulting, technical writing, and training for clients and audiences across the country. For more information related to integrating solar with radiant distribution, check out some of the resources Vaughan has developed:
- Standardizing Solar Combisystems, PM Magazine. See nine key considerations for integrating solar and radiant.
- Ask the Experts: Hydronic Heating, Home Power magazine. Vaughan was asked to respond to a Home Power reader who inquired about the suitability for solar heating for new construction.
- Code Considerations for Solar Heating Systems, SolarPro magazine. This article examines various key installation requirements for solar heating systems.
- Solar Approaches to Radiant Heating, Heatspring. This course is designed for heating and solar professionals.


Solar radiant systems are commonly referred to as solar combisystems. In the current market, the most cost-effective solar combisystems are those that we consider as “domestic hot water plus” systems. These solar combisystems are designed to maximize the economics of integrating solar with domestic water heating and radiant distribution by providing a simple, elegant design that has its greatest benefit during the summer and shoulder seasons here in Maine.
For Maine clients seeking to offset large space heating needs with solar heating technologies, Insource Renewables has extensive experience with large volume heat storage and expertise with integrating solar with a variety of heating appliances. The advanced complexity of these systems requires a renewable energy contractor you can trust with solar heating design and installation.
