As the cost of living continues to rise, many of us are looking for ways to reduce our expenses and lower our electric bills. One innovative solution is a super-smart thermal battery in the form of a WiFi-connected heat pump water heater.
For residential use, these thermal batteries are nothing new. They have been sold on the U.S. market for about 15 years by large distributors through nationwide hardware store chains. These devices work like your kitchen refrigerator but in reverse. Instead of pulling heat out of a cold space and releasing it outside, they pull heat from the surrounding air and transfer it into the water in the tank.
The concept behind thermal batteries is simple yet ingenious. They convert electrical energy into heat, which can then be released at a later time with very little loss. In contrast to lithium-ion battery installations, which have round-trip efficiencies of around 90%, thermal batteries achieve an impressive efficiency rate of 98-99%.
