Water Heaters

Most water heaters work for about 10 years. As they age, though, they can start to experience small issues that affect your day. Suddenly, you don’t have enough hot water for everyone in your family to take their morning showers. Aid Plumbing provides maintenance and repair service to extend the life and improve the functionality of your water heater.

Eventually, you will need to replace your water heater. Aid Plumbing has experience installing a wide range of water heaters. Whether you want a conventional storage water heater or a tankless system, we can install your water heater correctly to give you years of reliable hot water.

Tankless Water Heaters

“We were tired of running out of hot water, high energy bills and the idea of constantly heating a big old water storage tank. That's why we asked our contractor to install a Navien Premium Efficiency (NPE) tankless water heater. We researched the Energy Star website and found Navien on top of the energy factor list. Now we get endless hot water when we need it and we’re not heating water when we don't.”

Tankless Water Heaters

All the hot water you need, for as long as you need it.

How it works

  1. When a hot water tap is opened, the tankless water heater detects the flow

  2. The flow sensor activates to determine the amount of hot water needed

  3. The igniter activates

  4. The gas control valve opens to supply the correct amount of gas

  5. The fan and venturi activate to provide the correct amount of gas and fuel

  6. The premix burner ignites providing a flame to heat the water

  7. Cold water is pre-heated in the secondary heat exchanger

  8. Pre-heated water passes from the secondary to the primary heat exchanger

  9. The unit determines outgoing set temperature and adjusts the flame to heat the water

  10. Heated water moves to the buffer tank

  11. Desired hot water amount delivered to the faucet
