Why should you consider a tankless water heater? Because tankless water heaters provide homeowners with a variety of advantages that tank heaters do not.
1.Space Efficiency
Modern tank-style water heaters are more efficient and effective than ever before, yet the extra insulation has resulted in smaller tanks inside. Whereas you may have previously had an 80-gallon tank, you may now only be able to fit a 70- or 60-gallon tank in your heater space.
2. Improve Your Home Safety
Tank water heaters have a developing issue: their quick heating warms both the air and the water in your tank. Because air expands as it warms, the air in your tank can really exert a lot of extra pressure on the tank itself. Expansion tanks can help with this, but they are not a guarantee of safety. Similarly, relief valves that haven't been changed in a while may fail to open. All of this adds up to a rare situation in which a water heater could really explode and do extensive damage to your property.
3. Energy Efficiency
Because tank style heaters rely on maintaining your hot water at your preferred temperature, you must pay to heat the water once and then pay again to keep it at that degree. Regardless of how well-insulated your tank is, the water will eventually cool and need to be reheated. You only pay to heat your water once with tankless heaters, which means lower energy expenses and more money in your pocket.
