The Ultimate Hot Water Heater Buying Guide: Factors To Consider Before Making A Purchase


Water Heater Buying Guide

Water heaters are essential to any household, providing water for bathing, cooking, cleaning, and more. However, choosing the right water heater can be daunting with so many options available. In this ultimate hot water heater buying guide, you will learn the factors you should consider before purchasing to make sure you get the best water heater for your needs.

Type Of Water Heater

The first factor to consider when buying a water heater is the type of heater that will work best for your home. The two most common types are tankless and traditional tank-style heaters. Tankless heaters heat water on demand, so they don’t require a storage tank. They are more energy-efficient than traditional heaters but more expensive to install. Traditional tank-style heaters store water in a large tank and are less expensive to install but are less energy-efficient.


The next factor to consider when purchasing a water heater is the size. The size of the heater you need will depend on the number of people in your household, your daily water usage, and the temperature of your incoming water. You should choose a heater that can provide enough water without wasting energy by constantly heating excess water.

Fuel Source

Water heaters can be powered by a variety of fuel sources, including natural gas, propane, electricity, and solar power. The fuel source you choose will depend on your location, availability of fuel, and budget. Natural gas and propane are popular choices because they are cost-effective and energy-efficient. Electricity is a good choice if you don’t have access to natural gas or propane. Solar power is a renewable and environmentally friendly option but requires a significant investment upfront.

Energy Efficiency

Energy efficiency is an important consideration when purchasing a water heater. The more energy-efficient the heater, the less it will cost to operate, saving you money in the long run. Look for heaters with a high Energy Factor (EF) rating, which indicates how efficiently the heater converts fuel into hot water. Tankless heaters are generally more energy-efficient than traditional tank-style heaters but may require a higher upfront investment.

Installation And Maintenance

When purchasing a water heater, you should consider installation and maintenance requirements. Tank-style heaters require regular maintenance, such as flushing the tank to remove sediment buildup. Tankless heaters require less maintenance but may require periodic descaling to remove mineral buildup. It’s also important to consider the installation requirements, such as the space needed, ventilation requirements, and whether you need to upgrade your electrical or gas supply.


Finally, you should consider the warranty when purchasing a water heater. The right warranty can provide peace of mind and protect you from unexpected repair costs. Look for a warranty covering parts and labor that lasts at least 5-10 years.


Choosing the right water heater is an important decision impacting your daily life and energy bills. By considering the factors outlined in this ultimate hot water heater buying guide, including the type of heater, size, fuel source, energy efficiency, installation and maintenance requirements, and warranty, you can make an informed decision to meet your needs and budget. Consult a licensed plumber or HVAC technician to ensure your water heater is installed properly and safely.
