Why Tankless Water Heaters Are Gaining Popularity?
Tankless water heaters are slowly gaining its popularity among the people in the US. Although it has been widely used in different countries, there are many who still use the traditional type of water heating which requires a tank.
Tankless water heaters, or sometimes referred to as continuous flow, instantaneous or on demand water heater has been proven to deliver a lot of advantages to its users. And although it may require you to spend a bigger amount the first time you install it, but the benefit will last for a long time.
Tankless water heaters – Beginning of a revolution
At London in 1868, Benjamin Waddy Maughan- a painter, first realized the necessity of tankless water heaters. In the continuation of the realization, he first attempted to invent such thing. And eventually he partially succeeded. He invented the first instantaneous water heater. He named it after ‘Geyser’ – an Icelandic gushing hot spring. Still in many country, the term ‘Geyser’ is used to address tankless water heaters. After that, the concept of tankless water heater never looks back and we have found the current era of tankless water heaters.
How do Tankless Water Heaters work?
Unlike the traditional water heater where in you need to have a tank that will hold the hot water and wait for it to be used. Tankless water heaters are totally the opposite. These instantaneous water heater works by instantly heating the water that flows into the device as you turn the tap on. Users will have a constant supply of hot water and no need to save them on the tank first which might be inconvenient for long term use.
The electrical heating coil makes the water hot as it goes through and is only turned on when in use. This is because tankless water heaters have flow sensors which make it energy efficient as well. This avoids the possibilities of getting leaks and operates better compared to the other.
Installation of Tankless Water Heater
These particular type of water heaters are usually installed near where the water is to be used such as showers, kitchen, sinks or any other place inside the house where a source of water is required.
Because of this, users will be able to save energy as it eliminates the need for the water to go through long line of pipes in order to get heated water.
Due to its popularity, tankless water heaters are not limited only with the use of electricity as some runs on gas as well.Compared to storage tanks, tankless water heater use less space and does not require the need for buying huge tanks in order to maintain an amount of water that you have to reheat every now and then.
This definitely saves energy consumption especially for electric operated. On the other hand, using a gas unit requires an exhaust vent. Depending on the size of the building would also determine the size of the vent which will definitely use more energy eventually.
Advantages of Using Tankless Water Heater:
- Energy Saving – Since there is no need to reheat standby water in a typical storage tank unit, tankless water heater consumes less energy.
- Long Life of Usage – Tankless water heater usually lasts for a long time compared to traditional water heaters. With proper use and maintenance, it could last for about 20 years.
- Less Space Required – Having a space for a tank is not required. This type of water heater is simply mounted on the wall where the water supply is available while others may also be placed outside.
- Continuous Water Supply – Take longer time when in shower without worrying that your heated water will ran out. Tankless water supply offers endless supply of water and maintains temperature as you use them.
- Easy to Maintain/Repair – Compared to storage tanks, tankless water heater has replaceable parts that you can get in case in needs some repairs. This means being able to extend its service life and not force you to replace the whole unit or buy a new one.
It is truth that tankless water heaters are gaining popularity. But the point is, how fast? Well, the rate is slow. Here are some considerations that defy the fast growth of tankless water heaters.
Disadvantages of Using Tankless Water Heater:
- Cost of the Heater and installation process – Tankless water heater are more expensive to set up than traditional heaters. You have to buy the water heater unit which is usually about three or more times more expensive than setting up a storage tank type. Additionally, most of the time, tankless water heaters are mounted on the wall near the water supply, this may require more repair job and may need some alterations to the wall.
Moreover, for gas operated tankless water heaters, users are required to have vents which may not be so cheap at all. Bigger units require more vents as well.
- Limited Water Output – Since the water passes through the unit, the amount of hot water that it can produce is based on the size of the tankless water heater. Best example of this would be having more than two users at the same coming from the same water heater unit.
Selecting a tankless water heater will require some considerations when it comes to its energy efficiency, size as well as warranty. Some brands are more trusted than the others while a more expensive price may also follow. It is always best to have your house checked before shifting to tankless water heaters. For older houses, there might be a need to upgrade their power source as these types of heater will require more electricity in order to supply hot water for every unit in the house.
