There are both good and bad points to these types of appliances, the most notable positive being the energy savings. But there are also several other benefits of tankless water heaters, and some more negative considerations as well. Here are some important thoughts to consider about this type of home appliance.
1. Energy saving – According to a Consumer Reports study, the average home can expect a savings of around $70-$80 a year, as tankless heaters are about 22 percent more energy efficient than conventional tanks. There is no energy loss with tankless heaters, either, as they don’t have to continuously heat water in the tank when it is dormant, or not being used, which can be a good amount of time for a lot of homes. This can be a significant factor in cold weather. Tankless water heaters do not heat water that is not currently being used.
2. Water savings – Because you don’t have to wait for long minutes for the water to run hot out of the tap, you will use less water. The water in a tankless heater is hot right away, or maybe after just a few seconds.
3. Convenience and Comfort – With these on-demand appliances, there is no waiting time for hot water to replenish itself between uses. If two or more people take showers in succession, the second or third person need not worry about the hot water running out during his or her shower.
4. Lifespan – Conventional water tanks have a lifespan of around 7 years. On-demand tanks, however, have a lifespan of around 20 years, helping to offset their initial cost.
5. Less Space – Tankless heaters take up less space than traditional water tanks. You can then use that space for something else.
1. Costs – Tankless heaters cost around twice as much as conventional tanks. Tankless heaters cost between $800-$1150, while a conventional tank costs between $300 and $500.
2. Installation – Professional installation is necessary, adding to the cost, and, if you use natural gas, you may need to make expensive upgrades to your gas line. A venting system often needs to be installed as well.
3. Tankless gas water heaters are less efficient than tankless electric heaters due to the pilot light that burns continually on gas-powered models.
4. Lower Flow Rate – Multiple, simultaneous uses may overwhelm an on-demand water heater. In other words, running the dishwasher and shower at the same time could overwhelm the system and leave you in a cold shower. To surmount this obstacle, you will need to install a tankless heater at each hot water faucet, which could be a real pain and quite expensive. If you live in a large house, this may not be such a good option for you. You may want to look into solar water heating if you want to go green in those situations.
The Ugly (joking)
These have been in use in other parts of the world, such as Japan and parts of Europe, for some time. They are not the water-heating standard in the U.S. now, but perhaps, as they become more well-known, tankless heaters will become more common and less expensive. We hope tankless gas electric water heaters reviews has helped you make a better choice in your quest for a greener water heating option.
