- Solar hot water collectors – Roof panels absorb and transfer heat to water, providing hot water for needs like radiant heating.
- Solar air heating – Warm air collectors on walls or roofs can supplement forced air furnace systems.
- Passive solar design – Strategic building design naturally collects, absorbs, and circulates solar thermal energy through conduction, convection, and radiation.
- Photovoltaic panels – Generate electricity from sunlight to power electric furnaces, baseboard heaters, etc.
Solar energy is free, renewable, and available in most places. Solar thermal systems can provide up to 70% of a building’s hot water needs.
Geothermal Heating Solutions
Geothermal heating taps into underground warmth from shallow depths to provide heating and cooling via conductive heat pumps. Types include:
- Direct geothermal – Uses geothermal reservoirs from hot springs or geysers directly via a heat exchanger. Limited based on location.
- Closed loop – Pipes filled with water or antifreeze liquid circulate underground, transferring geothermal heat to a building.
- Open loop – Pumps draw groundwater to the surface, extract heat, and then discharges it back to absorption wells underground.
Geothermal systems have an average COP (coefficient of performance) of 3.5, making them very efficient. The underground temperatures provide heating in winter and cooling in summer.
Biomass Heating Solutions
Biomass heating utilizes organic materials like wood, crops, manure, and waste to produce heat through combustion, gasification, or pyrolysis processes:
- Wood stoves and furnaces – Directly burn wood pellets, chips, or logs to provide radiant and convection heating.
- Pellet stoves – Burn compressed wood or biomass pellets with very high efficiency and low emissions.
- Biomass boilers – Larger scaled systems that allow the use of agricultural residues like corn cobs or nutshells for hot water and steam.
Locally sourced biomass is a renewable fuel option in many locations. Advanced stoves and boilers optimize efficiency while minimizing harmful particulate emissions.
Heat pumps transfer thermal energy between indoor and outdoor environments via refrigeration principles. Key types are:
- Air-source heat pumps – Extracts warmth from outdoor air, even at cold temperatures, to heat indoor spaces and water. Reversible for air conditioning.
- Ductless mini-split heat pumps – Scalable, zoned heating and cooling for specific rooms without ductwork.
- Ground-source heat pumps – See geothermal heating. Water-source heat pumps use well or pond water.
Properly sized and installed heat pumps can provide all heating and cooling needs efficiently through heat transfer instead of heat generation like traditional systems.
Hydronic or radiant heating uses a network of pipes and pumps to distribute heated water from a central boiler to warm spaces through convection and radiant heat.
- Below floor – Pipes are embedded in floors to radiate gentle warmth directly.
- Baseboards – Heated pipes or electric resistance coils in baseboard radiators along walls distribute warmth.
- Radiators – Standalone cast iron or steel radiators heat rooms through a combination of radiant and convective heat.
Hydronic heating allows decentralized heat generation from any fuel source and provides comfort through radiant warmth and adjustable zone control.
Benefits of Eco-Friendly Heating
