Usually, we buy water heaters once in a long while. Either when we build a new home and are shopping for a water geyser for it or when our current water heater is faulty and needs replacement.

Therefore, given that we utilize water heaters for several years before finally getting another opportunity to replace them, it would be best to choose wisely.

Here are six factors to consider before buying a water geyser.

1. Type Of Water Heater

Different water heaters fall into these five general categories:

• Conventional storage water heaters: These come equipped with a storage tank or reservoir to store the hot water required for everyday use.
• Tankless water geyser: These tanks heat water directly on demand without using a storage tank.
• Heat pump water heaters: Instead of directly heating the water in a tank, this type of water heater transfers heat from one place to another. Result? A significant reduction in heating costs and higher efficiencies.
• Solar water heaters: These heaters rely on the sun’s heat to provide hot water, thus resulting in cheaper energy bills. Solar water heaters are ideal in hot areas due to the abundance of sunlight and heat.
• Indirect and tankless coil water heaters: These kinds use your home’s space heating system to provide hot water.

2. Fuel Source

Residential water heaters usually use either electricity or gas as their fuel source. Gas-fired water heaters might be categorized into propane or natural gas water heaters.

They require special ventilation for safety and health purposes. However, one advantage of gas models is that they have lower operating costs. The low cost allows you to offset their initial higher up-front costs.

Electric water heaters may initially cost less but have higher operating and water heater repair costs, which will cost you more in the end.

3. Energy Efficiency

Next to the HVAC system, the water geyser is one of the largest consumers of energy in the home. Prudently select a water heater with higher energy efficiency. 

4. Type of storage

As mentioned earlier, water heaters can either have storage tanks or are tankless. The heaters with storage tanks continually heat and store hot water.

They release hot water from the top of the tank while letting in cold water from the bottom to replace the used water, thus ensuring that the tank is always full.

The tankless water heaters (also known as on-demand water heaters) direct cold water into a unit and heat it as needed. These tankless water heaters also ensure that the hot water never runs out.

However, in a large household, where several people require hot water at once, the limited flow rate typical of tankless water heaters might bring an issue.

5. Storage Capacity 

Depending on the family size and the hot water usage, you need to select a water geyser with a suitably sized tank. A large household may require more water to run the dishwasher, wash laundry, and take several showers daily.

Thus, these activities need a larger-sized water heater or a tankless water heater. These tanks can deliver a high amount of hot water in a short time.

6. Space Required

It is also essential to ensure that the water geyser fits into a space. For instance, you can find wider and shorter boilers that can fit into areas with limited headroom, such as under cabinets.

Tankless water heaters also take up much smaller spaces when compared to traditional storage tanks.

Conclusion

When choosing your water heater, the factors above-mentioned should be enough to point you in the right direction.
