SETS Systems Electric Tankless Water Heaters are the only electric tankless water heaters listed and/or certified by UL (Underwriting Laboratories), CSA (Canadian Standards Assoc.), CEC (California Energy Commission) and HUD (US Dept. of Housing and Urban Development) for whole house use equipped with the patented, NASA-designed flow switch. As of January 2000, SETS was the only tankless water heater approved for installation in HUD approved housing. No other manufacturer of tankless water heaters can match our Lifetime 100% Parts Replacement Warranty (including heating elements) to the original purchaser.

In addition to our line of residential tankless water heaters, we also offer tankless commercial boosters for existing systems and an electronic Pool and Jacuzzi heating system, only 24" x 21" x 4" in size, that will heat your pool or Jacuzzi faster than anything on the market.
