Tankless gas water heaters are designed and manufactured to be highly efficient. They provide an on demand supply of hot water, heating water as it is needed. Because of the efficiency, they can save you a large sum of cash over their lifetime. Efficiency in the case of a tankless water heater means a large tank of water isn\'t constantly being heated and reheated, wasting precious gas everytime it fires up.

In fact, these instant water heaters are so economical that even though they cost more than the traditional models, they are much cheaper over their lifetimes. In fact, gas costs can be cut in almost half and those savings add up. As a result, they help reduce the emission of greenhouse gases making them more environment friendly.

Different models can be used indoor or outdoor, depending on the application. Output from different models range from 6 gallons per minute up to 13 plus gallons per minute, again depending on the application. Tankless systems are used in residences, commercial real estate or anywhere a constant source of hot water is needed, really.

Although tankless water heaters provide a constant flow of hot water and are energy and cost efficient, the one down side is that the delivery of hot water is not instantaneous. The water does need to be heated nd when you turn on a faucet you will notice a difference in how long it take for hot water to arrive.

Nonetheless, this small price is more than offset by the benefits. Plus, most tankless water heaters qualify for federal energy tax credits, at least for now, and even some states are kicking down a tax credit, too.

There are lots of great models on the market, but some of the most popular are from Rheem, Noritz, and Takagi. They are well liked for their durability, cutting edge features (like digital controllers), and efficiency. When it comes time to change out your water heater, consider a tankless gas water heater. Your bank account will be glad you did.
