Tankless water heaters have come a long way since they were first introduced and while they are still quite expensive, the savings that you can achieve in the long-term are worth the extra money. After all, these water heaters can last more than twenty years, while also providing you with more energy efficiency than regular water heaters.
Here are 4 things to consider when choosing a tankless water heater:
Consider Your Temperature Rise
The area of the country that you live in will determine what your temperature rise is, and you need to know that number prior to purchasing your tankless water heater. To determine your temperature rise, you need to subtract your ground water temperature from the temperature that you want from your water heater. If you want to shower in water that is one hundred and ten degrees and your ground water temperature is sixty degrees, then your temperature rise is going to be fifty degrees.
Calculate Your Flow Rate
Your flow rate is determined by adding all the GPM for the water fixtures that you will be using at once. The flow rate of a bathroom faucet is normally between a two and a three, while a low flow shower is between a one and a two. You may want to purchase a tankless water heater that has a circulation system add on included, so you do not need to make any changes if the hot water is not reaching your faucets quickly enough.
The Size that You Need
An average shower will use just over two and a half gallons of water at a temperature of one hundred and ten degrees. If you want to have only one shower going at a time, then you can get away with a smaller tankless water heater than you would if you needed two showers going at once.
The Type to Purchase
There are two different types of tankless water heaters and they are the point of use and whole house. The point of use systems will only heat one or two outlets, which is helpful if you want all the hot water from that tank to only reach those areas of your home. The whole house ones obviously send hot water everywhere inside your home. Most point of use models are electric, while whole house options normally use gas or propane.
If you have been hesitant with tankless water heaters over the years, now is the time to reconsider. You will be amazed at how well the newer tankless water heaters work and how much money you can save after you have one installed.
