Why continue using old and energy-inefficient heaters when you already have a wide variety of more advanced options to choose from? The brilliant minds of the world have definitely come up with newer technologies including water heater systems that are not only reasonably priced but also environment friendly through better energy efficiency or maximization.
Tankless gas hot water systems, demand water heaters, and point of use water heaters have become increasingly popular in recent years. They are more cost effective, fairly easy to have installed, flexible, they require less maintenance and they provide an endless supply of hot water. They also take up less space in your utility room and are far more attractive than their larger more cumbersome tank heating counter parts.
One of the best examples is the tankless water heater, which is also known as on-demand or point-of-use water heater. Though it is more expensive than the tank water heater, it is still within the range of a budget-conscious consumer. Further, considering that space is already a premium these days, the tankless water heater fits easily into cramped or small spaces. It’s therefore highly recommended to those who are living in condominiums and apartments.
It is also on demand since it doesn’t store water. Instead, it allows the flow of water, then heats it up, only when you need one. In the process, the amount of heat loss is greatly reduced.
This is quite different in how the tank water heater systems work. In it, the water is stored in a large tank that accompanies the heater. The burner already works, so even when the water is stored and not yet used, it’s already heated. But there’ a slight catch to it: the longer the water stays in the tank, the higher are the chances it will start to cool down. Hence, the system has to work again to maintain or bring back the water’s heat, which then leads to some loss. The energy used to heat the water previously isn’t maximized because the water isn’t used, and yet you produce more energy to keep it warm.
Gas Used
There’s also a difference when it comes to the amount of gas used. Both can actually make use of instant gas burner; however, according to studies, the burner that is adopted by tankless water heaters are more energy efficient as it consumes less, about a third than that of a tank water heater. It also has a very long life span of around 15 years, depending, of course, on how you take care of the system.
The Limitations
Nevertheless, regardless of how great the system is, there will always be limitations, or cons, as others would call it. When it comes to the tankless instant gas water heaters, one of the hurdles is the installation process. Because it’s quite complicated, you may need the technical supervision or support from specialists. Second, the lack of tank could mean very limited water output. It may not be the best system to select by a household composed of several family members.
