The Capacity of the Tankless Water Heater

When purchasing the best water heater for a smaller family, capacity is the most critical factor. This is important because a smaller family has limited requirements for hot water. If you purchase a tankless water heater that can process 7-10 gallons per minute (GPM) of water, then your heater will be consuming more energy.

Also, the initial costs of such heaters can be higher as well. So, it won’t be wise of you to pick such tankless heaters for a family of only two or three individuals. Therefore, you need to make a prudent decision in this regard. You can see the flow rate, BTUs, and wattage requirement for estimating the capacity of a water heater.

Source of Power of a Tankless Heater

Another important pre-purchase consideration for you is never to overlook the power source required by your tankless heater to operate. Generally, you will find tankless water heaters with different power sources like electricity, natural gas, and propane. In this regard, it is totally up to you to decide based on your preference. For example, if you want to use a tankless heater for the kitchen and bathroom, you can go for the ones running on electricity. You will need to install them indoors to get an instant hot water supply.

On the other hand, if you are a camping individual, you might be looking for a tankless heater that runs on propane. Also, if you don’t want its expenses to be added to your monthly electricity bill, you can go for tankless heaters that are fully functional outdoors without needing any installation. Therefore, you will be able to save your money and time by making the right decision about the power source of the tankless heater you will purchase.
