A Guide To Water Heaters

In most cases, homeowners tend to wait until their water heaters break before buying a replacement. Since they are usually in a great hurry to reestablish their hot water supply, these people are often incapable of making the right purchase. This is an unfortunate scenario, given that the prices and the costs of operating a new water heating system can vary widely, depending on the model, brand, and type of the system.


Thus, to avoid facing the same scenario, it is advisable to do a thorough research. Therefore, to help you find and purchase the best water heating system, we will go through some key features you should pay attention to.

Power Efficiency

For starters, power information and power variables are two relatively important features you should pay attention to. The most important indicator here is the EF (Energy Factor). This number is based on how efficiently the heat from the source is transferred to the water. It also encompasses cycling losses as well as standby losses, which are represented as a percentage of heat loss from the stored water when compared to the heat content.

Simply put, the higher the Energy Factor, the more efficient a water heating system is. For example, water heaters that feature electric resistance have an EF rating of around 0.8 to 1.0, gas heater types have a score of around 0.5 to 0.6, oil water heaters have an EF rating of 0.8, whereas pump water heaters have a rating that ranges from 0.45 to 2.0. To be sure about the EF ratings, do not forget to pay attention to the product literature that the manufacturers provide, as it usually contains this information. If you cannot find it, try contacting the manufacturer or its appliance manufacturer association.

Storage Capacity

Now, if you end up buying an undersized heating system, you will end up constantly facing hot water shortages. On the other hand, if you purchase a system that is too big, you will just waste power and water. With all this in mind, make sure to determine your needs and look for a system that can meet them. If you were not entirely sure about this, your best option would be to purchase a tankless water heater, which allows you access to hot water when you need it.

Circulation & Restoration Rate

Lastly, if you intend to purchase a storage-type water heater tank, you should familiarize with its restoration rate, which indicates how quickly it warms the water. For example, you can find 50-gallon devices, which have a restoration rate of around 54%. Such a system will provide 54 gallons of hot water, alongside an added 60% of the total tank capacity.
