How Does a Tankless Water Heater Work?

The benefits of going tankless for your comfort and wallet

Are you in the market for a propane water heater replacement? If your hot water system is approaching 10 years of service, it’s probably starting to struggle. Maybe your showers aren’t lasting as long as you’d like. Perhaps you’re waiting too long for your kitchen tap to heat up.

If you’re in the market for a new water heater, we recommend that you consider making the leap to a tankless system. At TF Complete Heating & Cooling, we can help you choose a propane tankless water heater that will significantly upgrade your hot water production and save you money on fuel costs for years to come.

Tankless water heating step by step

1. Your water heater detects that a hot water tap has been opened in the house.
2. Its flow sensor determines how much hot water the tap requires.
3. The igniter activates, and a gas control valve opens up to supply the necessary propane.
4. The fan and venturi activate to provide the correct amount of gas and fuel.
5. The premix burner ignites. This produces a flame to heat water.
6. In the secondary heat exchanger, the unit preheats cold water. This preheated water passes from the secondary to the primary heat exchanger.
7. The water heater determines outgoing set temperatures. It adjusts its flame accordingly.
8. The heated water moves to the buffer tank, then to the faucet.
9. When the tap is closed, the water heater switches off.

Benefits of a tankless water heater

We recommend that homeowners consider switching to tankless systems because they have some undeniable benefits. These include the following:

• Virtually unlimited hot water. Tankless water heaters are great for households that run multiple appliances simultaneously. You won’t need to choose between bathing and running the dishwasher!
• Energy cost savings. With a tankless unit, you won’t constantly heat and reheat a tank of unused water. This makes tankless water heaters 24 to 34 percent more energy efficient than storage tank units. The average house saves $150 a year in energy costs!
• Space considerations. Tankless units are more compact. They will save about 12 square feet of floor space.
• Longer lifespan. A tankless water heater can last for 20 years before needing to be replaced. That’s roughly twice the life expectancy of a storage tank water heater.

Some people are reticent to make the change to a tankless water heater because the upfront cost is higher. But the investment in fuel efficiency more than offsets the additional water heater installation expense.

Heating water comprises almost 20 percent of the average American household’s energy use. Going with an efficient, effective tankless water heater not only lowers your fuel expenses; it also significantly improves your quality of life.
