In our quest for the best tankless water heater, we recently put the ThermoMate 27kW Instant Hot Water Heater to the test, and the results were impressive. With an ability to deliver up to 6.4 gallons per minute, we can confidently say that this unit is perfect for our residential needs, providing an endless supply of hot water for showers and household chores. The self-modulating feature was particularly noteworthy, as it adjusted energy usage based on our flow demand, which not only optimized performance but also contributed to energy savings. At 240 volts and drawing 114 amps, installation was straightforward for us, and the compact design fit seamlessly into our space. Overall, the ThermoMate has transformed our hot water experience, making it a worthy contender for anyone considering a tankless solution.
