Types Of Gas Water Heaters

Storage Tank: Among the types of water heaters, this has the simplest design. Water is stored in the tank where it is heated, and then reheated if necessary.

Most manufacturers equip storage tank water heaters with a thermostat to control the water’s temperature. Tank sizes range from 113 to 378 liters to suit the varying demands of buyers.

Tankless Water Heater: This type heats water only when the tap is turned on, enabling it to give a continuous and unlimited supply of hot water.

Since it doesn’t make use of a tank, it can be installed almost anywhere in the house. And apart from being a space-saver, this type of gas water heater is energy-efficient.

Combination Boilers: Those in need of a water and home heater will benefit from this installation. Combination boilers heat water then pump it through the pipes running across the floor to heat your home.

These boilers don’t need furnaces, making them both cost-efficient and space-saving. They heat water with the use of either tankless water heaters or storage tanks.

How To Select a Gas Water Heater

Determine the size you need: Apart from knowing how much space you can allot for the water heater, you need to know how much hot water you’ll be using o a daily basis.

The easiest way to do that is by estimating your GPD (gallon per day) consumption, limiting your measurements only on activities and appliances that uses hot water.

Consider water consumption limitations: If you use hot water only on selected water outlets, gas-powered tankless water heaters may suit your needs better. These cost more, but are more energy efficient than storage tanks.

If, however, you want to control the consumption of hot water, the limits storage tanks carry will greatly serve your purpose.

Know the gas used in your house: The two most common gas connections are natural gas and liquid propane (LP). Because their properties are entirely different, manufacturers have to develop gas water heaters specifically for one or the other.

This means before you buy one, make sure it’s compatible with your gas connection. Because otherwise, you’d be left with no choice but to undo the installation, and spend more than you intend.

How To Maintain Your Gas Water Heater

Tap water carries millions of microscopic solids, chemicals and microorganisms. And should these not find their way through faucets and showerheads, they will build up in your water heater.

Draining the storage tank is the only way to get rid of these build ups because they settle at the bottom. Cleanups should be done annually, or as frequent as necessary depending on your water’s TDS (total dissolved solids) levels.

The unit should provide instructions on how to accomplish the job. Different manufacturers and different types of water heaters, after all, may list unique procedures.

Also, oxygen is an important component in burning gas, so the water heater would need ample supplies of it. A lack of it may cause damages to the burner chamber, and thus result to carbon monoxide leaks. This means you have to clear the unit’s surrounding to keep the room oxygen-rich.

Don’t forget as well to check for leakages. The worst it can do is help rust develop, but it will cost you a fortune in wasted energy and water.

How Gas Water Heaters Work

Both gas and electric water heaters work the same, no matter which type you go for. Where they differ is the need of the former for ventilation.

Storage tanks are cylindrical in shape, with the heater located at the bottom. Before any gas is released to make the heater work, the tank is filled with regular tap water.

Because cold water goes down, and hot water goes up, the heater gets to evenly heat the water. And because of the thermostat these are commonly equipped with, the water is heated to your needs.

Tankless water heaters, or on-demand types, don’t come with giant cylinders because they heat tap water instantly. These have what’s called copper heat exchangers and water only need to pass through them to get heated.

The by-product of these processes are called combustion gases and these need to exit through dedicated sealed vents.

If your home doesn’t have the required ventilation system, it is inevitable that you’d need one installed along with your gas water heater.
