Let’s discuss some factor of How does a tankless water heater work
What are tankless water heaters?
As the name suggests, tankless water heaters are appliances used to heat up water for domestic and other uses. However, the main difference between this and its predecessor is how they do not require a storage tank to store warm water.
Yes, you read that right. Tankless water heaters heat up your water-based upon your demand, then and there, rather than keeping it stored in a container that might lead to possible explosions in the future. In addition to this, the on-demand heating up of water saves you tons of energy compared to a storage tank heater. Furthermore, it promises to take your electricity and gas bills down considerably.
There are two main types of tankless water heaters, those that are powered by electricity and others that are powered by gas. Although both use completely different fuels to heat up water, they still share the same heating mechanism inside.
How does a tankless water heater work?
Functional on your demands completely, the tankless water heater does not start its operation until it receives the signal that you need warm water. This signal works by opening your tap in any part of the house. Once you have done this, cool water will flow through a pipeline towards the heating unit of the machine.
Depending upon what type of tankless heater you are using, this heating unit will either be an electrical element or a gas burner. Both of these will immediately start heating the water in the pipeline and then supply it toward that tap.
Seeing how these heaters heat your water only after you open your tap, it takes a longer time to get warm water in your taps as compared to a tank water heater. But, as these heaters do not store up water in a single container, the chances of water overheating and leading to a fire or explosion are drastically low in this latest mechanism.
Limitations of a tankless water heater
Perhaps the most confusing and problematic part of a tankless water heater is its restricted heating capacity. The amount of water that your tankless heater can heat every day depends upon the flow rate of the machine, measured in gallons per minute. This ranges from anywhere between two to five gallons of water per minute, based on the size and cost of these units.
Cost is another aspect that raises doubt in the mind of a buyer before they purchase a tankless water heater for their homes. These are sold at incredibly high rates and require professional plumbers to install the machine at your homes. Together, the charging cost by these plumbers and the overly expensive price of tankless water heaters do damage of about three thousand dollars to your pocket.
But trust us as we say that you will only applaud us in the future when your friends are looking for a new storage water heater since their last one was damaged by rain meanwhile your tankless water heater is still functioning properly. There is no comparison between the long-lasting durability of tankless water heaters with that of the traditional storage ones.
