Factors To Consider When Purchasing An Electric Tankless Water Heater
When purchasing a tankless water heater, there’s are some key important you should put into consideration, and they are discussed below:
Incoming Water Temperature
Some unit works great if they don’t have to increase the incoming water temperature above 30 F. However, most powerful electric tankless water heaters are not capable of raising the temperature to 50F, even with a reasonable flow rate.
Thus, for those staying in Canada or Northern U.S.A, you should consider purchasing a gas tankless water heater or a hot water tank capable of increasing the temperature more than 50F. On the other hand, people living the Southern U.S planning on using a heater during summer and spring months, a water heater powered by electricity is an ideal choice.
Flow Rate Requirements
There are several types of faucets and appliances in a home, all with different flow rate needs. For instance, a dishwasher or a washing machine will use far more hot water than a bathroom sink. Therefore, ensure you pay attention to the flow rate of the unit before purchasing. All in all, models offering high flow rate often comes with a hefty price tag and more electricity bills.
These products are available in different sizes, which makes it important to know the amount of space you have under your sink before buying. For people with tight areas under the bathroom or kitchen sink, you should consider units with compact sizes.
