How to Choose a New Water Heater for a Home

Choosing the right water heater will ensure that a home gets enough hot water while remaining energy-efficient.

Choosing the right water heater will ensure that a home gets enough hot water while remaining energy-efficient. But making the right choice isn’t always easy. So, here is a step-by-step guide on how to choose a new water heater for the home:

Determine the proper size

Size is among the most important factors when choosing a new water heater. The proper water heater tank size primarily depends on the household size. The larger the family, the larger the water heater they will need.

A general rule of thumb is to go for a 50-gallon water heater tank for a household of two people and add 30 gallons for each additional person. However, it’s best to talk to a professional so they can help with the selection of the correct tank size.

Consider the source of energy

Different water heaters are powered by various energy sources, including electricity, natural gas, solar, propane, geothermal energy, and oil. It’s best to opt for an energy source or fuel type that’s easy to access, reliable and affordable. For example, those who can’t access natural gas or propane are better off with electricity or geothermal-powered heaters and vice versa.

Those who live in areas that get a lot of sunlight can opt for solar-powered water heaters. On a side note, choosing a water heater powered by renewable natural energy can save money on energy bills.

Decide between the tank and tankless options

Water heaters come in two main types: tank and tankless. Tank water heaters store hot water in a constantly heated tank, which supplies it whenever needed. On the other hand, tankless water heaters heat water on demand, which means they don’t need a constant heat source (gas or electric) to ensure a hot water supply when needed.

Overall, tankless water heaters are more energy-efficient, as they only heat water on demand rather than constantly maintaining a tank of hot water. That way, a homeowner doesn’t have to pay to heat water they are not actively using. Unfortunately, tankless water heaters can be more expensive to install compared to tank water heaters.

Determine the budget

Water heaters can vary significantly in price, so it is crucial to determine the budget before making a purchase. Remember that while a more expensive water heater may have a higher initial cost, it may also be more energy-efficient, resulting in significant savings on energy bills in the long run.

Research and compare different models

Once homeowners know the right tank for their home, the available fuel or energy source, and the budget, they can start searching for and comparing different water heater models. Go for models that have good reviews and are energy-efficient. Also, consider the manufacturer’s warranty. A longer warranty can provide peace of mind and help save money that would otherwise go into repairs. If needed, seek recommendations from professional plumbers.

Work with a professional plumber

Homeowners who want to install or upgrade their water heater must work closely with a licensed and reputable plumber. Incorrect installation may lead to future problems and even void the manufacturer’s warranty. On the other hand, a good plumber can correctly set up a new water heater while ensuring it is safe and efficient.
