How a tankless “on-demand” water heater works
A gas tankless water heater is a popular alternative to traditional storage tank water heaters. Unlike storage tank water heaters, which store hot water for use, tankless water heaters provide hot water on demand, meaning they only heat water when you need it. This makes them more energy-efficient and cost-effective in the long run.
So how does a gas tankless water heater work?
First, when you turn on a hot water faucet or appliance, cold water enters the unit through a pipe. The water flows over a heat exchanger, where a gas burner or electric element heats the water to the desired temperature. The hot water then flows out of the unit and through your pipes to your faucet or appliance.
One important thing to note is that the term "on-demand" can be misleading when it comes to tankless water heaters. While they do provide hot water on demand, they may not deliver it instantly to your tap. The time it takes for the hot water to reach your tap depends on a few factors, including the distance between the heater and the tap, the size of the unit, and the flow rate of the water.
Tankless water heaters come in different sizes and can handle different flow rates, so it's important to choose the right size for your household's needs. If you have a larger household or a higher demand for hot water, you may need a larger unit with a higher flow rate to ensure you always have hot water when you need it.
Gas tankless water heaters are typically more energy-efficient than storage tank water heaters because they only heat water when you need it. This means they don't waste energy keeping a large tank of water hot all the time, which can save you money on your energy bills. Additionally, tankless water heaters can last up to 20 years, which is longer than the lifespan of a storage tank water heater.
Another benefit of gas tankless water heaters is that they take up less space than storage tank water heaters. Tankless water heaters are compact and can be mounted on a wall, which can free up valuable floor space in your home. This can be particularly beneficial if you have a smaller home or live in an apartment or condo.
In conclusion, a gas tankless water heater is an efficient and effective way to provide hot water for your home. While the term "on-demand" can be misleading, tankless water heaters provide hot water when you need it and can save you money on your energy bills in the long run. Additionally, they take up less space than storage tank water heaters and can last up to 20 years. If you're considering replacing your traditional storage tank water heater, a gas tankless water heater is definitely worth considering
