What Size Tankless Water Heater Do I Need?

There are essentially two kinds of water heaters that we have come across – the regular tank-based water and the new tankless water heater. However, lately, we have dealt with homeowners who needed an upgrade to a tankless water heater.

Unfortunately, most of them didn’t quite know the size that was best for them. You see, rarely will you find a one-size-fits-all solution for appliances such as these. You need to explore the unique factors in your home to help you determine the heater’s size for a more efficient solution. Therefore, to help you, we decided to break down what you need to look for when getting a replacement for your water heater.

Factors to Consider When Deciding on the Size of Tankless Water Heater 

  1. Flow Rate at Peak Consumption

Flow rate is expressed in gallons per minute (GPM), and it stands for the water that the water heater can produce at a given time. Let’s say you have dishwater that runs on hot water, a couple of showerheads, and faucets. In such a case, running hot water on all these outlets might overwhelm a small tankless water heater. Something important you need to understand is that different water outlets have different GPMs. Therefore, add up the different GPMs for the outlets, and shop for a tankless water heater that can support the total of the GPMs without much strain.

  1. Temperature Rise Required 

Every groundwater has something known as feedwater temperature. This basically means the temperature that water already has on the ground. The water heater will heat the water from this temperature.

Now, to determine the temperature rise required, you need to subtract the desired temperature level from the feedwater temperature. With this information, you can choose the size that will heat up water effectively without consuming much power. Generally, water at 105 – 115 °F is considered ideal for everyday household use.

Temperature Rise Required 

Therefore, you need to consider a tankless water heater that can raise water temperature by the difference you arrived at, quickly.

  1. Source of Fuel for The Water Heater 

Basically, we have two variations of tankless water heater fuel source. These are gas-based and electric heaters. It’s well known that gas-powered tankless water heaters produce more GPM than electric units at the same temperature rise. An efficient water heater needs to utilize less power and still provide hot water. And lastly, electric water heaters might be a nuisance during power outages.

  1. Room for Installation 

The beauty of most tankless water heaters is that their sizes range between medium and standard travel bags. If asked, we would say that such a size-efficient and modern appliance is worth budgeting for.

Room for Installation 

You will be saving on room and bills since tankless water heaters provide hot water when in demand. Also, a tankless water heater can be easily mounted on the wall, making it safe for younger family members.

  1. Consult A Licensed Water Heater Installer 

The last thing you want to do is purchase an inefficient tankless water heater just because you skipped essential details. It happens. To avoid getting in such situations, call a verified contractor, like Preferred Services, and get customized recommendations based on your needs and abilities. Even better, having an honest installer inspect your heating system will help with a quicker installation.
