Looking for a new water heater? Here is how you can find the right one!

The cost of heating a water consumes approximately 20 percent of your family’s budget. Despite these costs, water heaters are usually ignored until they become damaged. In this article, we aim to provide the best criteria for choosing a new water heater, along with a display of different heater technologies, to choose the one that suits you best!

If your water heater is nearing the end of its life and you are considering replacing it before a problem occurs, you will be happy to know that you have better options, thanks to recent regulations in some countries that require water heaters to be energy efficient. Water heaters require a new storage tank to work more efficiently, and water heaters without tanks are more efficient in it.

Usually, homeowners replace the old water heater with one of the same kind that powers itself – natural gas or electricity. Switching from a water heater with a tank to one without a tank can be very expensive because it requires you to adjust plumbing and possibly your electrical system. But if you are building a new house or adding a heater to an existing house, installing a water heater without a tank may have an effective economic impact.

Consumer reports recently tested several electric and gas water heaters without branded tanks such as Bosch, Navien, Noritz, Rheem, Rinnai, Tempra, and Trutankless. Where the results were compared from those heaters with conventional tanks, as well as the water heater with an electric heat pump, which is different from the water heater with a tank.

After testing the heavy use standard, we compared the performance of soda water heaters and electric storage tanks with those of conventional tanks. The test used a high clouds pattern equal to using 84 gallons of water per day. This is the daily equivalent of bathing multiple times, turning on the dishwasher, washing one load of laundry, and turning on and off the tap several times. The test used an inlet temperature of 58 degrees Fahrenheit for gas models and 74 degrees Fahrenheit for electricity.

Since water heaters without tanks work similarly to each other, we calculated the average results for each gas and electric boost, and compared this result to the performance of conventional gas and electric gas tanks and the electric heat pump model.

Take capacity in consideration

Tank water heaters usually have 40, 50, or 55 gallons or more. The size you buy depends on the number of people who live in your home and the maximum water consumption. For example, a family of four can take several bathrooms, operate a dishwasher, and wash a load or two of laundry on an average day, for a total of 100 gallons of hot water or more.

As a result of recently updated efficiency standards, water heaters under 55 gallons now have a 4 percent increase in efficiency, while 55 gallons or more water heaters have efficiency gains ranging from 25 to 50 percent depending on the technology used – a pump Heat or condensation.

And don’t assume that the new water heater will be a good fit for your old place. Due to increased insulation and other efficiency improvements, some newer models may be wider and / or longer than the old water heater.

Of course, water heaters without tanks don’t have much water, so the number you’re looking for is a gallon per minute (GPM) rating. This is the number that tells you the amount of hot water that the heater can provide during a specific time period. The higher the GPM, the higher the unit of hot water. If you have a large family and multiple bathrooms, you will need a tankless water heater with a higher GPM.

Water heater types

Depending on how much hot water you use and how the water is heated (gas or electricity), there are several options. Some species are alleged to reduce energy costs by up to half the cost of regular storage models. But their extra costs mean that savings time may be longer.

Water heater with a storage tank

Storage tanks are the most common type of water heater. As the name implies, these consist of an insulated tank in which the water is heated and stored until needed, and then the water escapes from the tube above the heater.

There is also a valve to relieve temperature and pressure, which opens if it exceeds any of the pre-set levels.

Natural gas water heaters typically use less energy and lower operating cost (almost half) than electric water heaters, although it should be noted that gas models cost more at the time of purchase.

Tank-less water heater

Instead of storing water, water heaters without a tank use a technique to heat water as needed. It’s more energy-efficient than storage tanks but it only provides a limited flow of hot water per minute – about 3.5 gallons, depending on the temperatures of the water entering.

These heaters are best for people who don’t normally draw water for more than one use at a time – like showering.

Heat pump heater

This type captures heat from the air and transfers it to water. Uses about 60 percent less energy than regular electric water heaters. And while it costs more than just models of electric heaters, the installation is similar. But heaters of this type do not work well in very cold places and need to be placed in an area that remains around 40 degrees Fahrenheit to 90 degrees Fahrenheit.

Because the heat pump is at the top of the heater, this water heater needs 7 feet from its position from floor to ceiling. You will also need up to 1,000 cubic feet of uncooled space to catch enough heat from the air plus a nearby drain to drain the condenser.

Solar Heater

A surface-mounted cell absorbs the sun’s heat and transports it to a frozen-like liquid in a closed-loop system that extends to the water tank. It is best saved in summer, which makes it attractive for sunny and warm areas.

Condensed water heater

Condensed water heaters are an option if you heat with gas and need a unit with a capacity of more than 55 gallons.

These models have a tank like a conventional water heater, but they pick up exhaust gases that usually come out from the chimneys, wasting energy.
