5 Best Smart Water Heaters in 2023

Hi there! Welcome to the beginning of your exploration of smart water heaters. Though the name sounds so intelligent and futuristic, in terms of modern technology, they are regular water heaters improvised to reduce billings and space and control user-specific temperature conditions and other requirements using a smartphone/AI assistant.

Primary Differences between Smart and Conventional Water Heaters:

First, let us look at the need for Smart water heaters and later discuss how it differs from conventional ones. 

  1. A conventional one is fueled by gas and takes 30 – 40 min to heat water. 
  2. An electric water heater takes 60 – 80 min to do the job. 
  3. Apart from the heating time, emissions report statistics show that water heaters in the U.S. leak 91,000 tons of methane as uncombusted gas into the atmosphere. 
  4. On the other hand, electric heaters consume a lot of electricity to heat the water and keep it warm for our use.
  5. Water heaters with tanks faced a downfall due to the reheating that is required when the water cools down when we postpone the use of the hot water.

This gave rise to the invention of smart water heaters. Think of it this way: wouldn’t it be better to control the time and temperature at which you require hot water from a remote distance, to be able to monitor power consumption and reduce unnecessary heating, and even understand your need for hot water by monitoring the pattern of use?

Though smart water heaters are a bit expensive, their technology is loaded with new options and features you might still draw a lot of value from

  • It enables you to set a particular time and temperature for various purposes from hand washing to showering.
  • It reduces your monthly bill by monitoring your need for hot water, thus saving energy.
  • Since they are tankless, there is no need to reheat the water once it cools down.
  • It offers you the comfort of operating it from almost anywhere through a smartphone.
