The Best Tankless Gas Water Heater Reviews
Congratulations on making the decision to consider a tankless water heater for your home and welcome to our Best Tankless Gas Water Heater Reviews Guide. Tankless water heaters have been on the market for many years, however, in the United States and along with the rest of the Western world, tankless water heaters are relatively unknown and generally an uncommon sight in a U.S household. On the contrary, on other continents of the world, tankless water heaters are abundant and a dime a dozen in hotels and homes alike.
Given the many benefits associated with a tankless water heater, it is surprising that traditional hot water tanks are still the norm in the U.S even though the advantages of a tankless far outweigh those of a traditional hot water tank. Spread the news far and wide! Let’s see more U.S homes with tankless water heaters. The energy cost savings and environmental advantages of tankless water heaters are reason enough to begin the research and consideration of a new tankless water heater purchase. Tankless water heaters are the most environmentally friendly and budget friendly option.
So let’s take a look at our Best Tankless Gas Water Heater Reviews Guide (that’s a mouthful!) and if you have any feedback or would like any additional information, please don’t hesitate to contact us!
Tankless Water Heater Considerations
Incoming Water Temperature
Incoming water temperature is an essential factor when considering a tankless water heater. If you live in the northern states of the U.S, your groundwater temperature is going to be much cooler than the southern states. The average person, however, typically showers with a water temperature of approximately 105°. A tankless water heater will need to heat the incoming water at a greater rate and work harder if you live in northern states because your groundwater temperature will be much lower than the southern states. It’s worth noting that gas tankless water heaters do have a greater heating capacity. For northern state residents, a gas tankless water heater is likely to be a better option for you.
Use the below chart to identify the approximate groundwater temperature in your region.
Your overall water use will depend on how many occupants are living in your household and what appliances may be used at the same time. The volume of water that a tankless water heater is required to heat is measured in gallons per minute (GPM). A one or two person household will need a smaller tankless water heater; whereas a 4 person family household will require a whole house tankless water heater which on average heats 6.5 gallons or more per minute.
Use this chart to identify how many gallons per minute your water appliances will likely use on average.
Utility Services Available
First of all you need to know the available utility services in your area. A tankless propane water heater or natural gas water heater may not be an option for you if gas is not available. If you are limited to only the electric tankless heater variety, click here for our comprehensive electric tankless water heater reviews guide. If gas is an option for your household, continue reading for more information on the best tankless gas water heater.
Gas vs Electric Tankless Water Heater
Higher heating capacity than electric
Less expensive than electricity
Eliminates the possibility of flooding from ruptured or rusted out water tanks
Environmentally friendly; only the amount of water necessary at any particular moment is heated
Can be wall mounted, floor mounted, installed under your sink essentially taking up less room than a traditional water tank
High efficiency and reduced energy costs with no standby heat loss
Many U.S States are offering rebates of up to $200 for natural gas tankless water heaters.
Proper ventilation is required
More maintenance required than electric tankless heaters
So if you are considering a gas versus electric tankless water heater, weight up the above options and take all the considerations of both an electric tankless water heater and a gas tankless water heater to decide what the most suitable option is for your circumstances.
Condensing vs Non Condensing Tankless Water Heater
What is the difference between a condensing and non condensing tankless water heater?
Tankless water heaters create a byproduct in the form of steam which cools and then condenses. The condensation is acidic and causes corrosion (hence the use of stainless steel heat exchangers). Non-condensing units vent the steam through corrosion resistant venting and the energy is essentially wasted. A condensing tankless water heater will recycle the additional heat and vent any remaining water vapour that is unessential for the heating process, making a condensing unit a much more energy efficient product.
Ultimately, you as the consumer need to weigh up your choices to determine what the best tankless water heater for you is; however when you are weighing up a condensing versus non condensing tankless water heater, ensure you consider the efficiency, environmental benefits and value for money that a condensing tankless water heater provides.
Takagi Tankless Water Heater Reviews
The Takagi company was established in the 1950s and have been manufacturing high quality, innovative and eco-friendly tankless water heaters for the residential and commercial market over this time. Takagi manufacture a wide range of gas tankless water heaters that come in a range of sizes from small units with a maximum flow rate of 6.6 gpm to whole house tankless water heaters with a flow rate of 10 gpm. In our best tankless gas water heater guide, we review Takagi’s best condensing tankless gas water heaters in the small, medium and large tankless water heater range.
Takagi incorporate commercial grade heat exchangers in their tankless water heaters for added durability and reliability and are made of heat-resistant copper alloy, which is significantly stronger than the standard copper used in other heat exchangers. Takagi’s heat exchangers are resistant to the effects of erosion that can contribute to maintenance issues such as leakages.
The secondary heat exchanger, which is where the rest of the heat transfer occurs is made of high quality stainless steel. The lower temperature causes acidic condensation to occur and stainless steel is used (rather than copper) in the secondary heat exchanger to avoid any corrosion. Takagi’s condensing water heater design using both copper and stainless steel heat exchangers for optimal efficiency and durability is indicative of Takagi’s innovative and high quality designs.
Takagi incorporates exceptional safety features into each and every one of their tankless water heaters, providing assurance and peace of mind to Takagi customers. Takagi has developed a unique feature that provides continuous monitoring and maintains proper combustion at all times. The Air-Fuel Ratio (AFR) Sensor, combined with the onboard computer adjusts the fan motor speed to allow for a proper mixture ratio for the air and fuel with the outcome of minimizing emissions and maximizing efficiency.
To prevent any freeze damage that may occur, every Takagi tankless unit includes freeze protection, making a Takagi tankless heater suitable for sub-freezing conditions. The freeze protection system ensures that the water temperature within the heat exchanger does not drop below a certain level.
Takagi have also designed a way to ensure that the water temperature does not exceed unsafe levels. The Hi-Limit Switch activates by disengaging the gas valves and shuts down the tankless heater.
