Tankless gas water heaters are an increasingly popular solution for homeowners who want to save energy and money while supplying hot water to their homes. Tankless gas water heaters work by heating up water as it passes through the unit, rather than storing heated water like a traditional tank-style heater. This means they can provide an unlimited supply of hot water and use less energy overall, saving you time and money in the long run.
There are many advantages of installing a tankless gas water heater, including: cost savings, space saving, safety, and more. With a tankless model, you don’t need to worry about running out of hot water or constantly refilling and reheating a large storage tank. You also won’t need to worry about replacing the entire system if something goes wrong—just replace or repair the individual component that is causing the issue.
When selecting a new tankless gas water heater for your home, there are several important factors to consider: GPM (Gallons per Minute), Installation Requirements, Size of Unit, Safety Features and Durability.

When buying a tankless water heater, you’ll need to know the flow rate in Gallons Per Minute (GPM). A family of 4 should look for a tankless water heater that can produce about 7 gallons of hot water per minute. Most families use about 6.5 GPM during peak times.
To determine the size of the tankless water heater, you’ll need to know how many appliances your family will use simultaneously. A tankless water heater that produces 4 GPM can simultaneously supply one shower and one appliance.
Tankless water heater size is important for both installation and operating costs. When a tankless water heater is undersized, it won’t produce enough hot water to meet your family’s demand. Taking two showers and running a dishwasher can use up to 6.5GPM – a 4 GPM tankless water heater can’t heat enough water to meet this demand.
To make sure you get the best gas tankless water heater for your home, begin by considering how much hot water you need and what type of fuel source is best for your needs. When shopping for a gas-powered tankless water heater, there are several factors to consider:
• GPM (Gallons Per Minute) – calculate the total GPM you need to meet your hot water demands.
• Type of gas – determine if you need propane, natural gas, or a combination of both.
• Location – make sure there’s a safe place to install the heater (most models require venting and an outdoor installation).
• Temperature Rise – calculate the difference between the incoming water temperature and your desired output temperature.
• Sizing – look at sizing charts to help determine the best heater for your needs.
With these factors in mind, you’ll be able to find the best gas tankless water heater for your home that best suits your needs. Be sure to read reviews and ask questions before making a purchase. Good luck!
We do not recommend installing gas water heaters on your own – it is better to involve specialists for this. The exception is portable gas heaters, which you can install yourself by following the instructions.
Tankless water heaters work by instantly heating up cold water when it runs through the unit. The heater has a flow sensor that detects when hot water is being used in your home, and then fires up a gas burner or electric element to quickly heat the incoming water. This eliminates the need for a storage tank to hold hot water. As a result, tankless water heaters provide hot water as you need it and can save energy by not having to reheat stored water. Tankless water heaters are usually smaller than traditional tank-style units, making them a great choice for homes with limited space. They also last longer and have lower operating costs than tank-style models. Be sure to read reviews and get professional advice before you make a purchase. Good luck!
