Important factors to consider!
Before, you get excited and start buying stuff, take a minute to consider these important factors before buying the best gas tankless water heaters.
• Size of tanks– determining the size of the tank depends on how big or small your family is. A big size tank will be more expensive to manage and a small size tank will mean less hot water for some family members.
Therefore, you can estimate how much water is required for members and appliances alike and make your decisions accordingly.
The best thing to do would be to install one general water heater and several small ones to facilitate the required appliances. The gas water heater is usually installed closest to the appliance requiring hot water to reduce time constraint
• Type of fuel– though there are many types of water heater fuels, the two most prominent ones used in the households are gas and electric water heater types.
- Gas fuel- gas fuel required more maintenance and is considered more expensive compared to the electric type, but it heats more ounces of water and is usually used where a large volume of hot water is consumed daily.
In this article, we will mainly talk about the best gas tankless water heaters.
- Electric fuel- this is considered to be low maintenance and inexpensive, which is sufficient for a common household. Another advantage of this fuel type, is it hardly required venting (essential in gas type), due to which we can place this type of fuel virtually anywhere.
However, it does not have as much volume capacity as that of the gas heater type.
Maintenance– A gas tankless water heater is an important investment that requires constant maintenance. Experts recommend getting the water heater checked professionally at least once a year, especially even living in a colder climatic condition or if you have constant hard water.
Gas-powered water heater requires more maintenance than electric ones, but it’s suggested to get even the electric ones checked by an expert at least every two years
