Please help us build an intelligent open appliance heat exchanger to improve efficiency and save energy! This project will reclaim countless wasted kWh per year from appliances such as:
- Hot water heaters
- Heating Units
We hope you can see the benefit of this project towards a sustainable lifestyle, energy efficiency, and the energy economy.
- High efficiency bar & plate heat exchanger technology borrowed from expensive race car intercooler designs for high flow rate, handles hundreds of degrees, and high pressure.
- Easily cleaned stainless steel fine mesh lint filter in the inlet.
- Standard 4" duct inlet and outlet manifolds.
- High efficiency sensor driven electronic fan controller unit .
- Demoed saving more than 2600 Watts!
Appliance waste heat is an inefficient use of energy resources that could be improved with the use of simple robust technologies for energy reclamation. This project was motivated by a few facts:
- The rising cost of energy causing financial burdens during seasonal heating.
- The economic impact of wasting energy and using fossil fuel resources inefficiently.
- Thousands of kW are being wasted by appliance waste heat.
A Simple Yet Powerful Idea
Passive heat exchangers have existed for energy reclamation, gaining popularity in recent years due to rising energy cost. We've made a smarter, less expensive, active heat exchanger.
This intelligent heat exchanger is an open hardware, open source solution for reclaiming energy from home appliances. It is inexpensive and utilizes the most advanced core construction. We've implemented a thin walled bar and plate heat exchanger with turbulator fins to maximize efficiency.
With a built in electronic controller it measures the temperature of the heat exchanger and compares it to the room air temperature. If the controller senses there is energy to be reclaimed, it activates a quiet, high efficiency fan to draw the heat out of the exchanger fins. This means the fan only runs when there is energy to be saved, greatly improving system efficiency.
- The intelligent heat exchanger is a great way to save on your home heating bill in the winter by reclaiming lost energy from appliances.
- The intelligent controller does its job quietly, and only when there is energy to be saved.
- Reduces burden on home heating equipment.
