Tankless Water Heaters
Are you tired of running out of hot water in the middle of a shower or bath? Are you looking for a more energy-efficient way to heat your water? Look no further than tankless water heaters from Aqua Science.
What is a tankless water heater?
A tankless water heater is a device that heats water as it flows through the unit, rather than storing hot water in a tank like traditional water heaters. This means you’ll never run out of hot water, and you’ll save energy and money by only heating the water you need.
How do tankless water heaters work?
Tankless water heaters use a heat exchanger to heat water as it flows through the unit. When you turn on a hot water tap, cold water enters the unit and is heated by a gas burner or electric element. The heated water then flows out of the unit and to your faucet or shower head.
Benefits of tankless water heaters
Tankless water heaters offer a number of benefits over traditional water heaters:
- Endless hot water supply: You’ll never run out of hot water, even with multiple appliances running at once.
- Energy efficiency: Tankless water heaters use less energy than traditional water heaters, which can save you money on your utility bills.
- Longer lifespan: In Arizona, a tankless water heater can last up to 20 years, compared to 5-8 years for traditional water heaters.
- Space-saving design: Tankless water heaters are compact and can be mounted on a wall, freeing up floor space in your home.
Types of tankless water heaters
There are different types of tankless water heaters: electric and gas and condensing vs non-condensing.
Electric tankless water heaters
These water heaters use electricity to heat the water as it flows through the unit. They are typically smaller and less expensive to purchase and install than gas-fired tankless water heaters, but they may not be as powerful and may take longer to heat the water. They also require a dedicated electrical circuit with sufficient amperage to power the unit.
Gas-fired tankless water heaters
These water heaters use natural gas or propane to heat the water as it flows through the unit. They are generally more powerful than electric tankless water heaters and can supply hot water to multiple fixtures at once. Gas-fired tankless water heaters require proper venting and a gas line to the unit, which can increase installation costs. They also require periodic maintenance to ensure efficient operation.
Condensing vs non-condensing tankless water heaters
A condensing tankless water heater is a more advanced type of tankless water heater that captures the heat from the exhaust gases and uses it to preheat the incoming cold water, making the unit more efficient.
A non-condensing tankless water heater, on the other hand, simply exhausts the hot combustion gases outside and does not recover any of the heat that is lost in the exhaust.
It’s important to choose the right size tankless water heater for your needs based on the number of people in your household, your hot water usage patterns, and the climate in your area. A professional installer can help you determine the appropriate size and type of tankless water heater for your home.
