Water heaters are appliances commonly used to heat water for households or industrial units. They are available in different sizes with best water heater brands, models based on their utility, storage, and decor choice.
Generally, there are two water heaters types available in market stores or online:
1) Tank water heater
2)Tankless water heaters
Tank water heater Is a storage-tank water heater that is easy to install. However, nowadays, Tankless water heaters have become more popular as it is an electric on-demand water heater with modern technique. It provides a continuous and instant supply of hot water on demand. Comparatively, they consume less space and also have a higher life span.
Features of Tankless Water Heaters
Various traits due to which the Tankless water heating system is preferred
➣ Energy saving
➣ On-demand for water supply
➣ No tank installation
➣ Convenient and efficient
➣ Lesser space
➣ Lesser wastage of money
What Types Of Water Heaters Are There?
Various types of hot water heating systems are as follows
➣ Electric Tankless water heater
➣ Gas-Fired Tankless water heater
➣ Propane Tankless water heater
Electric Tankless Water Heaters
The electric Tankless water heater is a water heating machine powered mainly by electricity. It is a good option for households having a low usage of water.
How do they work?
They contain superheated coils that store a small amount of water in it. When you open the tap, the cold-water travels through the pipe into the unit where the loop is installed. The coils steadily heat the water and in exchange supplies constant hot water. They can provide approximately 2–5 gallons of water per minute.
Gas-fired Tankless Water Heaters
A gas-fired unit is a heating machine powered by natural gas. The tankless water heater cost of this appliance is low. They produce higher flow rates than the electric ones.
How does it work?
It contains a gas valve and sensor installed within the unit. When you open the hot water tap, the sensor detects the flow and ignites the burner. The heat exchanger heats the flowing water and stores the warm water until it is required.
Propane Tankless Water Heater
It is the most efficient electric water heater as it gives an output of a higher volume of hot water with versatile and innovative technology. It utilizes less energy and also has fewer emissions. Comparatively, this Tankless water heater prices less.
How does it work?
As you turn on the hot water faucet, the installed sensor activates the propane gas burner which heats the water. The heating process continues until the tap is turned off. The gas burner shuts off automatically.
Venting Of Water Heater
If you are planning to replace your existing water heater, make sure you choose the best water heater wisely. You should consider the venting process and types of venting to avoid unnecessary installation costs.
Types Of Water Heater Venting
There is an option of four types of venting
1. Standard Atmospheric Vent:
Venting process in these units is done through a chimney or a metal pipe extended up to the roof. As the warm air rise upwards, the hot gases created by combustion are pulled up by natural convection
2. Power Vented:
These units use an exhaust fan to vent out vertically or horizontally. Power Vented water heaters tend to be more fuel-efficient.
3. Direct Vent:
Venting sealed in these units. They use a concentric pipe and create a balance with the air intake and exhaust the combustion fumes.
4. Power Direct Vent:
It is a combination of both power venting and direct venting units. These models flexibly provide a solution to Tankless water heater installations that lack sufficient air for combustion.
Which Is The Tankless Water Heater?
The selection of the tankless electric or gas water heater can be determined by carefully considering the comparison of each following their price, utility, space, and circumstances.
A good quality electric water heater costs are lesser than the gas water heaters.
➣ Installation cost
Venting process of gas water heaters makes the installation costs very expensive.
➣ Operating cost
Natural gas is marginally cheaper to operate.
➣ Greenhouse impact
Electric water heaters produce no greenhouse gases
Gas water heaters require annual maintenance whereas the electric ones don’t need much support.
Electric Tankless water heaters are portable heater home depot. On the other hand, gas water heaters tend to have complicated vent processing.
Electric-powered units are considered to be a better choice. Due to the high installation cost of gas tankless water heaters, the owners consider electric units more practical. Moreover, electric units are home depot Tankless water heaters which provide longer warranties, less maintenance and are eco-friendly too.
On the other hand, a gas tankless water heater is only slightly cheaper to operate than an electric Tankless water heater. The gas units are high-efficiency Tankless water heaters due to their exceptionally high thermal efficiency.
