The secret of getting all the hot water you need—without a tank

When Minnesotans first hear about the beauty of a tankless propane water heater, they’re skeptical at first but they remain true to staying Minnesota Nice. They politely ask: How is it possible to get all the hot water I need if it’s not already stored away in a storage tank? Suppose I want to take a long, hot shower while someone else is running the dishwasher and washing machine at the same time? What is the benefit of a tankless water heater vs. a tank?

The secret is combining propane with tankless technology! A propane tankless water heater uses a flame so hot it’s not necessary to keep your water heated in a tank. You simply turn on a hot water faucet and a flow sensor will activate a propane gas burner to heat the water. The heating will continue until you turn off the faucet, which shuts off the gas burner.
