When it comes to choosing a water heater for your home, tankless water heaters make sense for more people compared to those that still use tanks. With better energy efficiency and an almost endless supply of hot water, tankless models like the electric tankless water heaters have a great advantage. But still, even when you have decided on using a tankless water heater for the home you do still have to decide whether to get one that uses gas or electricity.

Is there really a difference between a gas water heater and one that uses electricity? In many cases, using gas to heat your water is better as it is more energy efficient that electricity. Compared to electricity, gas also tends to heat up water faster plus it gives consistent heat. The Rheem Tankless water heater RTG74PVP is an example of a good tankless water heater that uses gas.

This Rheen tankless water heater will provide you with hot water that comes out of the tap hot and that stays consistently hot. You will never get cold blasts due to the hot water running out and the need for reheating the water. This is an occurrence that is only typical with tank systems. Since this water heater uses gas as a heat source, you also get fast hot water. Gas can heat in an instant, unlike electric.

Gas energy is more efficient than electric. With electric some energy will always be lost in the heating process. With gas that energy is retained and goes straight into heating the water. This is why a gas water heater can heat faster and hotter than an electric hot water heater. Additionally, running the gas water heater costs less than running the electric due to the energy efficiency of gas.

There are actually a few safety features built into this Rheem tankless water heater. To improve the efficiency and performance of your water heater, it uses an electronic ignition unit. You also no longer need to guess what temperature the water is because installed into the water heater is a digital thermometer that tells you exactly how hot the water is. You can rest assured that your family won't be suffering from sudden hot water burns. If you are concerned about gas buildup, there is a electric blower that forces the gas to be expelled outside. This will address the issue that any gas buildup might pose in terms of health and safety risks.

Obviously there might be some drawbacks when it comes to using a gas water heater. In this case, you might incur additional installation costs if you need to run gas piping into your bathroom. So you might want to check if your water heating unit is currently electric or gas. If you are replacing an old gas water heater with a new one, then there should be less of an issue about extra installation costs.

Would you choose a tankless gas water heater? Only if consistent hot water supply is important to you. Gas is more energy efficient than electricity, which should help reduce your overall power bill. Not to mention you do not need to suffer sudden blasts of cold water that often come with using a tank water heater. Gas water heaters are also generally more reliable and faster when it comes to providing you with hot water.
