Buying Guide For Takagi Tankless Water Heater Outdoor
Introduction Of Takagi
Takagi is one of the leading tankless water heater companies worldwide. They have been serving their consumers since 1952 by providing them high-quality products and solving their water and heat-related issues.
They are inventors in refining the thermal efficiency of the units. Their appliances operate on an air-fuel ratio sensor, ensuring your house and machine’s security.
They produce indoor and outdoor gas heaters for residential and commercial use. The residential ones have two types: non-condensing and condensing units.
The majority of their units work on natural gas, but some also use propane. The indoor ones require a direct vent for maximum energy savings.
Prices of Takagi propane tankless water heater are slightly higher than the natural gas ones. Moreover, the outdoor models are costly than indoor ones.
Installation Of Takagi Propane Tankless Water Heater
Takagi heaters are powered by natural gas and propane, so to confirm your security, you must hire a specialized plumber for the deployment. If you install it on your own, you will negate the guarantee.
Its installation is straightforward and takes the shortest time after you have selected the location where you want to hang it. If gas or recirculation pipelines are not required, the process will be even faster.
The installation of an outdoor unit is easier and faster than the indoor one. If you have to replace and dispose of your existing device, the deployment duration will increase.
The brand provides comprehensive instructions for installation; it means non-technical individuals can fix it without facing any problem.
Repair And Maintenance Of Takagi Devices
Users rely on Takagi because their products lack severe perfunctory issues. In the initial ten years, only 10 percent of consumers experience problems, and the majority of these issues occur due to incorrect deployment.
So, if you don’t want to deal with mechanical problems, hire professional installation services and keep up with maintenance.
Like other heaters, Takagi appliances also need regular maintenance and inspections to ensure they are in good working condition. Other than that, additional care is not imperative.
What Are The Types Of Takagi Heaters?
There are mainly two types of Takagi units: gas-powered and propane-fired heaters. You can choose any type depending on your house and preferences. Let’s understand what the difference between the two is.
Portability And Usability
Natural gas is useful for bigger houses where warm water is needed continuously in different areas for various purposes like baths, laundry, and much more.
If you live in a colder climate, you should pick natural gas as a fuel because it performs efficiently despite temperature drops.
On the other hand, propane gas is portable than natural gas because it comes in containers. It may seem like a problem for many folks as cylinders take some storage space.
But you should take it as an advantage because you can put the canisters in any corner of the house. You can take advantage of it to fuel other appliances such as a washing machine, dryer, stove, and others.
Propane gas is delivered in canisters, but natural gas comes through pipelines that dispense it in the entire house. These pipes are not available in many parts of the world.
If your area or residence does not have gas pipelines, you should buy the propane-powered Takagi indoor tankless water heater. However, if you want to install the gas one, you will need to upgrade your house’s infrastructure.
According to stats, natural gas is cheaper than propane, and it is measured in price per cubic foot. Besides, propane is measured in cost per gallon. The actual price depends on various factors. Nowadays, we use BTUs or British Thermal Unit to calculate the price.
BTU refers to the heating efficiency of Takagi commercial tankless water heater. Propane’s BTU rating is 2490, and natural gas’s rating is 1030, which means gas is cost-effective. Propane is also beneficial as it is cleaner and ignites well.
What Sort Of Warranties Does Takagi Offer?
The warranty gives a sense of confidence and security to customers, and the creators of Takagi are familiar with this concept. That’s why; they offer a limited guarantee to their consumers.
With the guarantees, the users obtain some legal rights, and these rights may differ from country to country. Takagi provides three different sorts of warranties: a 15-year heat exchanger warranty, a 5-year parts warranty, and a 1-year warranty for labor.
The parts warranty means if any of the unit’s components are not functioning accurately in the initial 24 hours of deployment, the brand will be liable to fix them.
The heat exchanger guarantee means if the stainless steel or copper exchanger fails within 15 years after installation, the brand will fix it.
The warranties are appliance only if a certified plumber and electrician will install the heater; otherwise, you won’t be able to enjoy the benefits of warranties.
What Are The Features Of Tankless Water Heater Takagi Review?

Takagi tankless water heater vaunts a commercial-grade copper alloy heat exchanger with 8X strength than regular copper, making it sturdier. It is more resistant to rust and corrosion than other heat exchangers.
Moreover, 25% thicker drums avert the destructive effects of thermal development after various burning cycles.
In the condensing heaters, the 316L stainless steel secondary exchanger is responsible for taking care of the rest of the heat distribution. Stainless steel is used for making this exchanger because the lower temperature could cause acidic condensation.
Air-Fuel Ratio (AFR) Sensor
In terms of safety, the manufacturer took things to the next level by installing a distinct air-fuel ratio sensor. This sensor observes the quantity of used air and fuel 24/7 to guarantee a balanced grouping between materials. It is necessary as it delivers combustion and reduces gas leakage.
Overheat Cutoff Fuse
When there is a combustion breach, the heat exchanger’s surface absorbs excessive heat. In such a case, this feature will turn off the heater.
It prevents the water temp from reaching unsafe levels. Nobody wants to get burned during their shower, so it separates the gas valves when the temperature surpasses the safe limit and turn off the appliance.
