Water heaters are classified in two main ways. You can classify them according to their construction design to get conventional storage water heaters, tankless water heaters, and hybrid heat pump water heaters. You can also classify them according to the type of fuel that they use to get electric, gas, and solar water heaters. The most commonly used method of classifying water heaters is by construction design. This is mainly because you can get a conventional storage water heater that uses electricity or gas. The construction design of a water heater determines its cost, efficiency, and even warranty. In the United States, conventional storage water heaters are the most popular models. Tankless water heaters are gaining popularity due to their high efficiency. Solar water heaters are also becoming more popular by the day because they use renewable energy and are hence very efficient. Today we are only going to discuss tankless water heaters. You will be told what they are, their pros and cons, and where you can buy them.
What Are Tankless Water Heaters?
Like the name suggests, tankless water heaters have no storage tank for holding or storing the heated water. This is the main difference between tankless water heaters and conventional storage water heaters and hybrid heat pump water heaters. The latter two come with hot water storage tanks or reservoirs. Tankless models have no hot water storage tanks but rather heat water instantaneously or on demand. That is why they are also called on-demand or instantaneous water heaters. Let us now look at the advantages and disadvantages of tankless water heaters.
Advantages Of Tankless Water Heaters
The main advantage of tankless water heaters is that they are very efficient. They do not have a storage tank for holding the heated water and hence do not suffer standby heat loss like the conventional storage tank models. This means that tankless water heaters have lower operating costs. Another major advantage of tankless water heaters is that they take up less space because they are compact. Tankless water heaters supply hot water the moment they are turned on. There are no delays like in the conventional storage models. Tankless water heaters require less maintenance and last longer. You will not request Cincinnati water heater services regularly if you buy a tankless water heater. They come with warranties of about 10 years and they last up to 20 years. This is almost double the lifetime of conventional storage water heater.
Disadvantages Of Tankless Water Heaters
One major drawback of tankless water heaters is that they cannot supply hot water for simultaneous usage or applications. You have to either use the shower or the washing machine; or else install multiple water heaters. Another disadvantage of tankless water heaters is that their flow rates determine their capability to supply enough hot water at the right temperature. Also, electric tankless water heaters require more starting power to heat the water instantaneously to the required temperature. And finally, gas powered tankless water heaters with pilot lights waste energy.
Where To Buy Tankless Water Heaters
You can buy a tankless water heater from various retail outlets. You can also consult your local plumber for advice on the best model and size to buy. Some plumbers even supply water heaters to their clients.
