Understanding The Basics Of A Tankless Gas Water Heater
Overview Of Tankless Gas Water Heaters
If you’re in the market for a new water heater, you might be wondering whether a tankless gas water heater requires a dedicated circuit. To answer that question, it’s essential to understand the basic workings of a tankless gas water heater.
Here’s what you need to know:
- Unlike traditional water heaters, which store and heat a specific amount of water in a tank, tankless gas water heaters heat water on demand.
- When you turn on a hot water tap, cold water flows through the unit’s heat exchanger, where it’s quickly heated by gas burners. This means that you’ll never run out of hot water, and you’ll only pay to heat the water you use.
- Tankless gas water heaters are available in both whole-house and point-of-use models, and they come in both indoor and outdoor configurations.
How They Work To Heat Water
Now let’s dive deeper into how tankless gas water heaters work to heat water.
- Gas-powered tankless water heaters use a burner to heat the water as it passes through the heat exchanger. The heat exchanger is typically made of copper, which is an excellent conductor of heat.
- As the water flows through the heat exchanger, it absorbs the heat energy from the burner, raising the water temperature to the desired level.
- Once the water temperature reaches the set point, the burner turns off. This means that tankless gas water heaters are more energy-efficient than traditional water heaters because they only consume energy when you need hot water.
Differences Between Tankless And Traditional Water Heaters
Finally, let’s take a closer look at the differences between tankless gas water heaters and traditional water heaters.
- As we’ve mentioned, tankless gas water heaters heat water on demand as you need it, whereas traditional water heaters store hot water in a tank.
- Because tankless water heaters don’t store water, they take up less space and are often more energy-efficient.
- However, tankless water heaters may require more upfront investment, and they often have higher installation costs. Additionally, because they heat the water as you use it, they may not be ideal if you have a high demand for hot water simultaneously in multiple locations.
- Traditional water heaters, on the other hand, typically have a lower upfront cost and can handle a higher demand for hot water at the same time. However, they can be less energy-efficient and may run out of hot water if you use more than the stored amount.
Whether a tankless gas water heater requires a dedicated circuit depends on the specific model and local electrical codes. However, understanding how tankless gas water heaters work can help you make an informed decision when shopping for a new water heater.
