First, How Much Hot Water do You Need?

To begin, you need to determine how much hot water your household requires at peak times. To get an accurate measure, take notes of the number and size of appliances you use that require hot water such as sinks, showers, dishwashers, and washing machines. You also need to find out their flow rates. The more items that need to be heated up at once, the higher capacity tankless water heater you should look for. 

For instance, if you have a household of four people with two showers running at the same time in the morning along with the dishwasher, you need to add the flow rates of both showers and the dishwasher. That gives you your home’s peak hot water demand. The higher the number, the more power you need in your tankless water heater.

Next, Select a Fuel Source

When selecting a fuel source for your new tankless water heater, it’s important to consider what’s available in your area. The most common options are natural gas, propane, and electricity. Gas-powered models usually provide higher flow rates and energy-efficient heating, while electric units may take up less space. Electric water heaters are also cheaper to purchase, but they cost more to run. 

Depending on your home’s layout, a gas unit might require additional venting or piping, which could be costly. However, it might be the most cost-effective option if you already have a gas line in your home. Tankless water heaters that run on propane can be a good choice for houses that do not have a natural gas connection.

Do You Require an Indoor or Outdoor Model?

You can choose to mount your tankless water heater either inside or outside of your home. If you go with an indoor unit, pick a model designed for the space you have and meets local code requirements. Outdoor models are typically cheaper, and easier to install but also require extra protection from weather conditions such as snow and rain. You should consider what type of climate your home is in and pick the model that best meets your needs.

How Much GPM And BTU Do You Need?

GPM, or gallons per minute is the amount of hot water that a tankless water heater can provide. The higher the GPM, the more powerful your unit will be. If your household has a high hot water demand, then you need a tankless water heater with an equally high GPM.

BTU or British thermal units measure how much energy a water heater uses to heat up one gallon of cold water by one degree Fahrenheit. It’s important to consider BTUs when selecting a tankless water heater since it will determine the flow rate and hot water output of your unit.

Other Features to Consider

Along with GPM and BTUs, tankless water heaters come with a variety of other features. Some models may have an Energy Star rating which can help you further save money on your energy bills. You should also check for additional temperature control settings that allow you to adjust the hot water output levels for different tasks such as running the dishwasher or taking a shower.

But most important is the recirculation technology. This technology helps to save water and money by circulating heated water from the tankless heater into other cold-water outlets instead of having to wait for it to be heated each time. If you want the convenience and efficiency that comes with a recirculating water heater, then make sure to select one with this feature.

Don’t Forget Warranties

Finally, don’t forget about warranties. Most tankless water heaters come with at least a limited warranty, but some may offer more coverage than others. Make sure to read the fine print before making a decision.

Finally, Choose Your Tankless Water Heater

Once you know how much hot water your household requires along with the type of fuel source, consider the various models available on the market. Look into the energy-efficiency ratings and safety features such as temperature settings, recirculation technology, and any additional warranties that may be available. By researching the different models and taking into account your own individual needs you can find the perfect tankless water heater for your home.

Let’s Talk About Installation

Once you’ve selected the right tankless water heater for your home, it’s time to install it. Make sure to hire a professional installer who is familiar with local building codes and can correctly set up your unit. The entire process may require some plumbing work and electrical wiring, which could be costly. However, if you already have a gas line in your home, it might be the most cost-effective option.
