Welcome to Tanknot

Tankless Water Heaters are an efficient, cost-effective alternative to conventional "heat-and-store" hot water tanks. Used in Europe and Japan for decades, provide hot water on demand instead of constantly storing it 24 hours a day, 365 days a year. A tankless water heater will pay for itself many times over. A tankless heater not only costs less to operate every single month, it will also last up to four times longer than a conventional hot water tank. Tanknot Tankless, Inc. is California premier tankless installer. It was founded by a registered mechanical engineer and plumbing contractor in the State of California.

Why Tankless?

  • Saves up to 50% on gas
  • Endless Hot Water
  • Environmentally Friendly
  • Extra Space in the Home
  • Lasts three times longer than a tank
