Customer Testimonial:

"I replace my SETS 22kW tankless water heater with a Hubbell 21kW. The customer representative I contacted was very knowledgeable and very open in his comments about the SETS problems of the past".

Here are my comments:
1. There is no comparison between the SETS and Hubbell Tankless Water Heater. The Hubbell unit has been completely reengineered to meet the highest industry standards.
2. We have not experienced any temperature fluctuations during showers, even when other hot water appliances are in use.
3. The new temperature display and adjustment is easy to adjust and the temperature is accurately displayed.
4. I also received a discount for my old SETS unit, which I return back to the factory free of charge.
5. The new Hubbell unit is complete silent. Conversely, not so with SETS.
