Review of Takagi T-H3-DV-N Condensing Indoor Tankless Water Heater

Next time when you’re getting your energy bill for using all that hot water doesn’t act surprised. You don’t have any excuse for paying so much when almost everybody around you switched to tankless water heaters decades ago.

Joke aside, the tankless water heaters have been on the market for some time now, with the ability to cut down your energy bill being their selling point.

Why should you turn to tankless water heaters?

The fundamental principle for tankless water heaters is that they give hot water on demand, until the end of time. They don’t have a tank to collect the boiling water and don’t use energy for maintaining the water hot. No tank and no fuel when not in use result in less energy consumed, which reduces your energy bill from the very first month.

Since the water only goes through the system and doesn’t collect in a tank, it doesn’t have the time to cause damage or corrosion to the system. Minerals such as calcium and magnesium are harsh on pipes, especially if your water is hard. Just because water doesn’t get to stay in the system, doesn’t mean you shouldn’t protect the unit, nevertheless. Be cautious and also install a water softener for your tankless water heater, for expanding the durability.

It brings us to the next benefit of tankless water heaters, which is low maintenance. There’s no tank to take care of, and the majority of tankless water heaters only require some flushing once a year.

You may think that we got over all the benefits, but we’re not there yet. No tank also means less space needed for the installation. Tankless water heaters are small, compact, and only need 1/3 of the area that traditional water heaters with tanks may need.

Highly energy-efficient and dependable, tankless water heaters are an excellent investment for anyone living in the 21st century. The high price of gas models and professional installation (by a licensed plumber) are problems to consider. However, none of them should stop you from switching to tankless water heaters asap.
