Airthereal Electric Tankless Water Heater 18kW, 240Volts - Endless On-Demand Hot Water - Self Modulates to Save Energy Use - Small Enough to Install Anywhere - for 2 Showers, Evening Tide series

  • ☼ Save Space: That water heater in the basement or utility closet takes up a ton of space. This wall-mounted water heater uses 90% less space than a traditional hot water heater with a tank.
  • ☼ Safe To Use: With high temp protection, dry heating protection, and electrical leakage protection you can rest easily knowing you have safe, on-demand hot water to use on your schedule. The electric and fluid systems are completely separated to prevent electric leakage and water pipe corrosion.
  • ☼ Important Note: In order to install 18kW Electric Tankless Water Heater it requires 240 Voltage, 2 x 40 AMP Circuit Breaker Size and a set of 2 x (8AWG/2) wires. Please check to confirm that your breaker panel meet these specifications.
  • ☼ Endless Hot Water: Imagine you are the last one in your family to take a shower before heading out for the day. You turn on the faucet and the water is freezing cold. Too bad you don’t have an Airthereal Electric Tankless Water to provide endless hot water on demand with no preheating, temperature fluctuations, or running out of hot water in the tank.
  • ☼ Save Energy: Water is only heated when you need it, not stored in a hot water tank. The self-modulating temperature technology only uses energy to heat up water while you are using it to save up to 50% on water heating costs compared to a typical tank water heater.

Factors to Keep in Mind When Buying tankless electric water heater

We have prepared a list of guidelines to help you make an informed choice when buying tankless electric water heater online.

Know your needs

Before buying tankless electric water heater online, ensure you know exactly what you need and what your money should buy. For example, if you're looking for an anti-aging cream but don't have any wrinkles yet, don't waste money on this type of product until it's really necessary! It is important to know your problems with each purchase and whether the benefits outweigh their costs.

Do your research!

You've probably heard this advice before, but it's still true: never buy tankless electric water heater without reading reviews or doing some research first! The Internet makes it very easy to find honest opinions about almost any product on the market today; don't hesitate to read them before buying tankless electric water heater

Check the seller's return policy.

Make sure you know the seller's return policy before making a purchase. You may find that some sellers have policies that allow customers to return their products within 30 days of purchase or even 60 days if they're not satisfied with their purchase. This is especially important for large purchases like furniture because once it's delivered and assembled, it can be difficult to transport and return if needed.

Read reviews from previous buyers.

It's always a good idea to read reviews from previous buyers before buying tankless electric water heater online. These reviews can give you an idea about how well the item performs, whether there were any issues with shipping or customer service, and so on.

Buy from a well-known brand.

If you have your heart set on a particular brand, that’s the best product. For example, if you want to buy a Samsung S9 phone, you should shop for it online at the Samsung website or any other Samsung store.

Check the shipping options.

If you are ordering an tankless electric water heater online, make sure that the website offers free shipping so that you don’t have to pay tankless electric water heater extra after making your purchase. If there is no free shipping option, consider purchasing from another website that offers this service.
