It is undeniable that tankless water heaters are taking the lead right now in the industry. However, the question “which tankless water heater should I get?” still prevails. The reason behind that is the fact that there is a multitude of names and brands out there and that makes it so difficult to choose.
Nevertheless, it can be a lot easier to pick up your tankless water heater once you realise that you can find a lot of familiar names in this category. The thing is, most companies that make tankless water heaters right now are those who made chubby traditional tank water heaters a while ago. However, as tight as it is, the circle of “trusted names” is still pretty wide. Hence why this review aims at singling out one of the most reputed brands that goes by the name of ‘WaiWela’ and reviewing it and some of its best products in detail.
WaiWela is a prominent name in the water heating industry and that’s because it has been around for about 50 years now. Since 1977, WaiWela has been committed to energy conservation and environmentally sound products. This manufacturer’s main production line is focused around tankless water heaters of all sorts; from natural gas to propane to electric to point of use tankless water heaters, you name it. but, in this review, we will begin by looking at gas tankless heaters solely.

WaiWela Tankless Water Heaters Reviews
wFirst on the list is the WaiWela PHH-32ROFL which is one of the most powerful tankless water heaters in the industry as a whole, making it perfect for very large homes and even industrial use. With a continuous flow rate of 9.5 gallons per minute at 45 degrees temperature rise and 10.5 GPM at 35 degrees rise, this beast will take on any home of 5 to 6 bathrooms or even a small apartment building and believe me, it is that powerful.
The model at hand comes in various models to accommodate for all of your needs and all your preferences. Hence, the PHH-32ROFL has a propane model and a natural gas model; it also has an indoor and an outdoor model. If you think that’s nice, wait till you see the efficiency and user friendliness of this unit.
Speaking of which, this model has a wired remote control which makes temperature control as easy as it could get and saves you the whole guessing game of “how hot/cold is the water?” Also, this heater will take vertical like horizontal ventilation which makes it a lot more adaptable to smaller or awkward spaces.
Accordingly, this tankless water heater is easily one of the best options in the market. However, there is a bit more to it than just that. It’s necessary to keep in mind that this model is primarily designed for warmer climates which means that it will struggle in sub zero temperatures and might even cause some issues. Hence, it is important that you pick the most suitable heater for your geographical location because believe it or not, climate affects these heaters greatly.
Next on the list is the WaiWela PH2-28ROFL which is a powerful condensing tankless water heater. Similarly to the previous model, this one is able to generate a continuous flow rate of 9.5 gallons per minute at a 45 degrees temperature rise and 10.5 GPM at a 35 degrees rise which is immense. Hence, this should be perfect for you if you live in a huge house of 5 to 6 bathrooms or you own a small apartment building.
Again, this tankless water heater comes in multiple settings in order to accommodate for all your preferences: natural gas, propane, indoor, outdoor. Apparently, there isn’t much of a difference between the two models when it comes to numbers. However, beside performance, these water heaters are very different on the inside and outside. Thus, you must make sure to choose what’s best for you.
Accordingly, the WaiWela PH2-28ROFL promises the same options of control and overall use. Also, the model at hand is designed primarily for warmer climates as well and is not recommended for people who live in sub zero climates. All in all, if your profile matches the characteristics of this unit then you won’t be disappointed at all.
Third is the WaiWela PH2-25ROFL (indoor/outdoor – Natural gas/Propane) which is a slightly more docile unit but it’s still very strong. This water heater promises a flow rate of 8.4 gallons per minute at 45 degrees rise and 9.5 GPM at 35 degrees temperature rise which is powerful enough to fill a Jacuzzi in a few minutes. Therefore, this model would be perfect for houses of 4 to 5 bathrooms and that’s more than I can personally ask for.
The cool thing about this model is that it can be installed as part of a circulating water system. Also, to make your life easier, this tankless water heater comes with a built in electric blower which will help maintain your unit at its top performance.
Moreover, nothing exhibits trust like a handsome warranty and this WaiWela is no exception to the family. This model comes with a 12 years long heat exchanger warranty, 5 years on parts and 1 year of service for residential use. However, you must hire a licensed professional to take care of installation for you in order not to jeopardize your warranty.
Last but not least is the WaiWela PH2-20ROFL which is an urban tankless water heater that generates a continuous flow rate of 6.4 gallons per minute at a 45 degrees temperature rise and 8.4 gallons per minute at a 35 degrees rise. This unit can cater for a huge house of 2 to 3 bathrooms but it’s perfect for 2. Thus, if your house is bigger then you might consider picking up one of the previous models instead.
Again and just like most WaiWela, the PH2-20ROFL is a very compatible model as it comes in indoor/outdoor – natural gas/ propane versions to accommodate for your preferences. Also, and just like most WaiWela models, this one is equipped with everything necessary to facilitate the use and control of this machine and just like all other models, this one is also meant for warmer climates.
Other than that, the warranty on this tankless water heater is great and the quality is admirable. Hence, if you live in a warm climate zone and own a nice medium size home then you will never complain with this unit.
