Water Heater Buying Guide

As water heating is a major necessity for homes, there is a large amount of cost on this. It is almost 20% of the expenses of the average household. Apart from this daily cost addition to your bills, the maintenance cost of the water heaters would also add up to your expenditure. So, if you are looking forward to replacing your existing water heater or purchase a new water heater for your new residence, you should do background research on the available products. Inefficient water heaters might give you additional trouble of improper functioning and high maintenance costs. 

Hence, it is important to purchase a good product when looking for a water heater. As there are many products in the market, choosing the best might be challenging. This guide would help you consider all your requirements and go for the most appropriate. Here’s all you need to know when choosing a water heater.

How Water Heaters are Tested

The performance of gas and electric tankless water heaters is tested for the function of their conventional tank counterparts. The water was drawn in a pattern of 84 gallons per day. This is similar to the water used for daily tasks of showers, running dishwashers, washing machines, and kitchen requirements of an ordinary household. The testing was done with an inlet temperature of 58 ˚F for gas models, 74 ˚F for electric models, and an outlet temperature of 120 ˚F. The payback time for both new installation and replacement was calculated using the costs of purchase, installation, and annual energy costs. The payback time is longer for tankless units that were used as replacement solutions.

The capacity of Water Heaters

The average capacity of water that a water heater can hold is 40, 50, or 55 gallons. This capacity might even be more. The size should depend on the number of people in the house and the highest water usage. An average family of four uses a total of 100 gallons of water per day. However, this does not imply that a water heater of 100 gallons is necessary for this household.

The first-hour rating (FHR) of the water heater should be considered. This gives the number of water gallons that the heater can provide within an hour, starting from a full tank. This FHR value is indicated on the energy guide label of the product. It is required to calculate whether this FHR would work for your household requirements.

According to the recent efficient standards, water heaters with less capacity than 55 gallons have a 4% increase in their efficiency. The water heaters with 55 gallons or more have efficiency gains of 25% to 50%.

This would vary depending on the technology used. In terms of the area and dimensions, new water heaters are less likely to fit into the same old space consumed by the old water heater. As tankless water heaters cannot hold water, the rating is measured by gallons per minute (GPM). When this value is higher, more water can be delivered from the water heater. An average shower would require 2.5 GPM.

Types of Water Heaters

There are few types of water heaters for you to choose from. Some models are said to be reducing energy costs than ordinary ones. But due to the high initial investment, the payback time might take longer than the others.

Storage Tank Water Heater

This is the most common type of water heater, where water is heated and stored until required. The water is drawn out from the top of the water heater. The temperature and pressure relief valves open if the preset value is exceeded. Natural gas water heaters consume less energy and run at a lower cost which is almost half of that in electric water heaters. But the gas models cost more in the initial purchase.

Tankless (On-Demand) Water Heater

Tankless water heaters use heating coils to heat water and provide only a limited flow of hot water. This is about 3.5 gallons per minute and might vary with the temperature of inlet water. However, they are more energy-efficient and ideal for people who use water at a slower rate, without using water for simultaneous purposes. This is also suitable for houses that use natural gas as electric models need to upgrade the electrical capacity which is more costly.

Heat Pump (Hybrid) Water Heater

In this water heater, the heat from the air is captured and transferred to the water. Due to this mechanism, energy consumed is lessened by about 60%. The cost is higher than the electric model and the payback time is comparatively short.

This does not function efficiently in cold spaces and should be located in an area with a higher temperature of around 40 ˚F to 90 ˚F. There should be a clearance of about 7 feet from the floor to the ceiling because the heat pump is located on the top. It is also recommended to have a warm space of 1,000 cubic feet so that the heater can capture enough heat. A drain is also required to discharge condensate. These are the additional requirements of the heat pump water heater.

Solar Water Heater

This water heater consists of a roof-mounted cell that absorbs the sun’s heat energy and transfers the heat to an antifreeze fluid. This runs to the water tank through a closed-loop system. This system is an idea for sunny areas, but might be inefficient on gloomy days. Therefore, they have a backup system to be used when required. However, as you need to install a solar cell system, the return on your investment might take more time than the other models.

Condensing Water Heater

If you are using gas for heating purposes and require a water capacity of over 55 gallons, then the condensing water heater is an ideal choice. Similar to the conventional water heater, a tank is used in this. As the exhaust gases are blown through the coil, most of this heat is absorbed by the incoming water.

Features to Consider When Buying a Water Heater

The following are the important features that need to be considered when purchasing a water heater. By following these, you might also be able to identify the worst water heater brands to avoid.

Warranty

The average period of warranty offered is between 3 and 12 years. You can get additional warranty models with larger heating elements and thicker insulation. This would increase the rate of water heating and cause less heat loss. Therefore, a brand with a longer warranty would be the ideal choice.

Anti-Scale Devices

Some water heaters come with a swirling feature that reduces the build of mineral scale at the bottom of the tank. However, it is not necessary to go for such additional features as a longer or thicker element would serve this purpose. So a good water heater with a 12-year warranty would satisfy this requirement.

Brass VS Plastic Drain Valves

The drain valves are situated near the base of the water heater. Brass valves are more suitable as they are more durable than plastic valves.

Glass-Lined Tanks

Glass-lined tanks reduce the corrosion of steel elements. So purchasing tanks with this feature is beneficial for long-term usage.

Digital Displays

You can monitor the levels and customize your options using digital displays. There is a special vacation mode in some electric or heat pump hybrid water heaters. This uses that heat pump for added efficiency during long periods where the heaters are not being used. The collector temperatures, pressure readings, and other related details are indicated on the solar water heaters as well.

Conclusion

By inspecting the availability of these features, you can decide the best water heater for your requirement. Always make sure to avoid the worst water heater brands and focus on the recommended water heater brands. We hope you found this guide useful.
