What are the types of water heaters?

But before deciding what type of water heater of the A.O. Smith’s wide-ranging product list you should get, it would be wise to gain at least an introductory insight on the many types of water heater this company offers.

Back in the old days, there were only two types of water heater: tank and tankless. But, through time and countless innovations, such number has now gone up to five, with the addition of: heat pump (hybrid) water heater, solar water heater, and condensing water heater.

To get a better idea of how these five works, here are brief descriptions of each one:

  • Tank Water Heater

With the use of an insulated tank, this type of heater stores water in large volumes, keeps it warm, and delivers it when the need arises. Storage tank water heaters are also the most common among other sorts.

Tank water heaters are usually powered by natural gas. And although most of these units bear hefty price tags upon initial purchase, they also use less energy and costs less to operate, which in the long run, are better compared to electric-powered heaters. However, tank water heaters do require constant monitoring in order to avoid the pressure going over the allowable preset level. 

  • Tankless Water Heater

The tankless water heater delivers hot water on demand, hence the name. Instead of collecting great amounts of water in a tank for later use, this model typically uses specialized heating coils in order to instantly heat up the water that flows towards you.

Despite being energy-efficient, tankless water heaters can only pump around 3.5 gallons of heated water per minute, which tend to limit it to a single use at a time. With that in mind, a household requiring simultaneous hot water use, usually in larger families, is not optimal for this type of heater. 

  • Heat Pump (Hybrid) Water Heater

This variety transfers heat from the air to the water, which allows it to use about 60% less energy than your common electric brand. But, the installation of hybrid water heater is a bit sophisticated because of the way it operates.

For one, it needs about 7-feet ceiling clearance and up to 1000 cu. Ft. of uncooled area in order to properly collect heat from the air. You also need a drain to collect and dispose the condensate this type of heater produces. 

  • Solar Water Heater

Just as its name suggests, the solar water heater utilizes the power of the sun. Thus, the more sun exposure there is in your location, the more you get out of this one. But, the same can’t be said if you live in an area with frequent overcasts, nor is it viable in places susceptible to extreme winters.

  • Condensing Water Heater

Condensing water heater is a lot like the typical tank build, but with a more efficient way of saving potentially wasted energy. Unlike conventional water heaters, this one captures gases that escapes out the flue, which it then transports through a coil, heating up the inbound water in the process.
