How to Choose the best Water Heater?
Having a water heater in your house is a long term investment. Hence, you should be able to choose the best water heater that works perfectly for your house. With the right choice of a hot water heater, you can be able to use for about 15 years, without any difficulty. However, it is important to note in most cases, 15 to 25 percent of the energy, in most homes goes to water heating.
It is, therefore, necessary to understand the various options of water heaters that are available on the market. This would help you make a good decision so that you can find a hot water heater that would serve your needs in an efficient manner. It is worth noting that there are some heaters, that tend to consume more energy than others.
Hence, we give some important considerations when buying a water heater.
How much Sufficient Space You have?
As we all know, water heaters vary in height and diameter. If you are moving up in tank size, you need to make sure that you have enough space for the larger capacity. Also, some water heaters (usually heat-pump or hybrid types) need a certain amount of surrounding air. Hence, you need to plan for appropriate cubic square footage requirements. Water heaters that comply with current NACEA regulations may have more insulation than older heaters. Hence, these might be taller or wider than a heater they are replacing. However, check the specifications before buying if clearances are tight.
Natural gas is more affordable in most areas of the country than electricity. And because as it is more efficient, gas water heaters cost less to run. Among all electric water heaters, those heaters that use heat pump capacity offer considerable energy savings. However, that is certainly enough to offset their higher cost in just a few years. Tankless water heaters are another energy efficient option. But they have some negative points that might not make them a perfect fit for every situation. Regardless of the type of fuel source, all new hot water heaters are subject to the current NACEA energy efficiency regulations, that went into effect in April 2015.
Do you have a natural-gas service in your home?
If you are choosing a gas water heater, you definitely need natural gas service to your home. If you don’t have it, consider the additional installation costs of running a gas line. However, this is a work that is best left to plumbing professionals for safety reason. Gas heaters that run on liquid propane are also available but may cost more to operate in the long run.
Consider your Electrical Needs
Residential water heaters require electricity to run. In case of a gas water heater, that is standard 115-volt service for the ignition system. However, some just plug into a convenient outlet. Electric heaters, including tankless electric heaters, need 240-volt service, and a dedicated line that is rated sufficiently to handle their current draw.
Consider your Venting
Gas water heaters have to be vented to the outside of your house. This can be handled in many ways. Be aware that even while replacing one gas water heater with another, local building codes might have changed from your last installation. The best recommendation is to consult a licensed plumber to be sure that venting is done safely and adequately.
Heat pump Water heaters
These are water heaters that capture heat from the air and then pass it on to the water. As a result, they will end up using about 60% less energy than other conventional water heaters. While the initial price appears to be more, you will recoup this within a very short period of time, through the energy costs that you save. However, it is important to note that these may not be effective in cold places. Moreover, they would only be effective in areas where the temperatures range from 40 to 90 degrees Fahrenheit. When installing the hybrid water heater, you need the clearance of about 7 feet from the floor to the ceiling. This is to be able to accommodate the heat pump, that is usually on top. You can choose this type of water heater as an extension to the storage water heater.
Ample Hot water Capacity
The right-sized water heater can provide your family with all the hot water it needs when costing less in terms of upfront price and energy consumption. As an example, a 50-gallon hot water heater can supply enough to meet the needs of a typical family of four. When sizing a tankless hot water heater, consider both your climate and your family’s needs.
Sufficient First Hour Rating
The first-hour rating is based on the hot water stored in the tank and the amount of incoming cold water that can be heated within an hour. The higher the rating, the more hot water you can receive during peak usage times in your house. However, online calculators can help you determine what FHR you need.
Natural gas fuels generate nitrogen oxide pollutants. Hot water heaters with a low NOx rating shoot less into the surrounding air. However, some areas of California needs ultra-low NOx water heaters. Hence, California residents need to check the regulations before selecting the best water heater. However, AO Smith water heater is one of the best choices that can be suggested to the people living in such areas.
High recovery rate
The recovery rate relates to how quickly the hot water heater can produce more hot water after the initial supply has decreased. A low recovery rate means you may be waiting a while or taking a cold shower once you use the initial power.
High Flow rate
The High flow rate refers to the number of gallons of hot water per minute (GPM) the hot water heater can produce. Clearly, higher flow rates are useful in many situations.
You are suggested to choose a water heater with at least a six-year warranty. Some warranties cover only the tank and parts, and most brands that cover labor limit it to just one year (though some high-end water heaters offer better labor coverage). The best water heaters like AO Smith Water Heaters, come with warranties of 10 to 12 or more periods.
