4 Important Points to Consider while Choosing the Best Tankless Water Heater

selecting a tankless water heaterTankless water heaters are popular in Europe for decades, though North American consumers have been using the appliance only for the last two decades. A tankless water heater can bring your energy bill down by 24% to 34% if the usage of hot water in your family is 41 gallons or less and by 8% to 14% if you use more. Also, a tankless water heater will provide a continuous supply of hot water.

A tankless water heater works by moving through the system and heating the water rather than storing and heating water in a large tank that a tank-style water heater does. Because of this system, a tankless water heater can save a considerable amount of energy.

However, there are many types of tankless water heaters and while selecting a tankless water heater, you may have to consider some points in order to get the most suitable appliance for your needs. Here are some such points.

1.Flow

With a tankless water heater, water need not be emptied with a tall bath. The hot water supply is endless. The issue with this type of heater is flow and not capacity. It won’t run out of hot water unless the flow exceeds the heating ability of the heater. Thus, if there are 2-3 appliances running at the same time, a tankless water heater cannot heat a large amount of water and eventually deliver lukewarm water. Solution for this is to buy a unit that gives out plenty of heat. A more expensive option is to buy two tankless water heaters.

2. Warranty

Make sure to check the warranty of the tankless water heater you are planning to buy. Since it doesn’t have a tank that declines after years of usage, the best tankless water heaters come with a long-term reliability. The critical component, i.e. heat exchanger, comes with a warranty of five to twelve years.

3. Size

While looking for the best tankless water heater for your family, look for the best flow and not capacity. As mentioned earlier, a tankless water heater doesn’t run out of water but may not be able to heat water quickly to supply to multiple fixtures at a time. The flow rate is expressed in GPM (gallons per minute) and it ranges from 1.2 to 6 GPM. 1.2 GPM model can handle a single bathroom sink, while a 2.6-GPM model can supply to one shower at a time. A 4-GPM unit can handle one sink and one shower, while a 6-GPM unit can deal with two showers.

4. Efficiency Ratings

If you are concerned about energy savings, you should check a model’s efficiency ratings which range from around 78% to 87% for the best unit. They denote the amount of fuel converted to heat by the heater, the higher the better.

5. Reputable Brands

There are many tankless water heating brands available on the market, some of which are more reputable than others. You’ll want to stick with known names who can honor their long term warranties. Rheem has been in the water heating business for over 40 years and have a long track record of excellence. Rinnai is also in that category with over 35 years in business and some of the highest rated products in the market.

Consider these points and you can get your hands on the best tankless water heater for your family.
