What to Consider Before Buying a Tankless Water Heater

Tankless water heaters are a worthy investment. They provide several benefits, including energy conservation and an endless hot water supply. If you are considering installing a tankless system or replacing your traditional water heater with a tankless unit, here are some factors to guide you:


One of the first factors to consider is the size of the tankless shower heater. To get the right size, determine how much hot water you regularly use and the required temperature rise for your home appliances. This is contingent on the time it takes to heat water. The larger the unit, the greater the temperature rise required.


The maintenance of the water heater shower is another important consideration. Maintaining your appliance will depend on the type of unit you choose. Electric units only require regular simple cleaning, while gas-fueled ones need to get inspected apart from regular cleaning. Purchasing a gas-powered unit is a good choice if you can perform the extra maintenance. Otherwise, an electric unit may be preferable.

Energy Factor 

The energy factor assesses the unit’s overall efficiency. The greater the EF rating, the more efficient the unit. However, higher energy factor values do not always imply lower annual operating costs, especially when comparing fuel sources.


A good water heater often comes with an extended warranty. This is crucial, especially if the appliance breaks down in the future. The warranty will cover all of the components and parts of your water heater.


The climate in your area of residency also affects the tankless water heater you choose. The GPM (Gallon Per Minute) rating is determined by the temperature of the water entering your home. The colder it is outside, the more difficult it is to heat your water, thus, lowering your GPM.

Find a Reputable Plumber

When installing your water heater, asking for assistance from a trustworthy plumber is worth considering. A licensed plumber will obtain a permit and adhere to local building codes and manufacturer recommendations if necessary.
