Factors To Consider When Buying a Water Heater

  • Fuel source

Most residential water heaters use either gas or electricity as an energy source.

Remember to confirm if your heater uses gas as an energy source if it runs with propane or natural gas.

Gas heaters generally have an upfront cost and require ventilation when safely and healthy for use.

The gas heater, however, outweighs their upfront cost by their relatively low operation cost.

On the other hand, the electricity heater tends to have a lower initial cost but higher operational cost than its gas counterpart.

The critical thing to note when buying the heater is the type of energy available and reliable at home.

  • The efficiency of the energy

Regardless of the energy source, you chose for your heater, and water heating can be among the heavy energy consumers in your home.

Therefore, you need to select a new heater that does not waste your energy and cut on the cost of heating your water.

A right water heater should be efficient and meeting the federal energy standards.

Energy efficiency measures the effectiveness of utilizing energy and the rate of energy loss during water heating.

Go for a water heater with less energy factor.

  • Storage type

The most popular water storage is the tank water storage system.

The system operates by continuous heating of water and storing it in a tank that water flows through a tap.

Coldwater enters the bottom of the tank to replace hot water, ensuring that it is always full.

There is a heat loss with this system because there is continuous heating of water in the tank.

Final Thoughts

Some water heaters may be efficient but costly to buy, others may be affordable but with superior functionality as their counterparts.

Modern storage tanks have modifications that minimize energy losses.

On-demand or tankless water heater can help to cut unnecessary water heating costs by over 20%.
