Tankless Water Heater Shopping Guide
Comparing the Top 6 Choices in the Market
Tankless water heaters are a wonderful purchase. They save space while offering more efficiency in terms of energy consumption than most conventional water heaters. This is because they are small in size and provide warm water on demand.
However, the efficiency of a tankless water heater will depend on several factors such as energy source, usage, maintenance, and brand. Therefore, you should consider these factors when shopping for a tankless water heater.
We compared the top water heaters in the market right now, and here is what you should know about them.
Best Tankless Water Heaters For 2021
Let’s highlight the technical specifications and other features of the tankless water heaters.
1. Rheem 240V Heating Chamber RTEX-13 or RTEX-18
The Rheem 240V RTEX has a durable copper immersion with two heating elements which makes the field serviceable. This allows the power control to self-modulate. It also has a digital thermostatic control that can be externally adjusted easily, coupled with an LED display which offers a positive degree of accuracy. Moreover, it has a 99.8% energy efficiency because it has external controls that help adjust the temperature. The fact that it is threaded allows for an easy installation, replacement, and a digital display of temperature.
2. Rinnai RUR98IN
This is available in silver and is made of stainless steel. It has an indoor installation type with a ½” gas line compatibility. The innovative technology behind this heater offers a consistent hot water supply because of the recirculation capability. Also, the condensing technology has two heat exchangers providing it with maximum efficiency. Furthermore, it only requires a small space, close to that of a small suitcase. It also offers both PVC and concentric, thereby providing several venting options. It has a 96% efficiency. Even more interesting is the fact that it is Wi-Fi capable.
3. Rinnai RL Series HE+ Tankless
This tankless heater is powered by natural gas, RL75Ip propane type, and has a thermal efficiency of 82%. It has a minimum gas rate of about 10,300BTU and a maximum gas rate of about 180,000 BTU. It also comes with a digital controller with an added advantage of an error indicating code. It has an indoor installation and has residential and commercial temperature settings, with the former being between 980F and 1400F. The commercial setting is between 980F and 1600F. However, the commercial controller has to be purchased separately.
4. EcoSmart ECO 27
This tankless water heater is ideal for condominiums, apartments, and townhomes, among others. It is electric and is the largest among those powered by electricity, with original self-regulating technology. This makes it among the most efficient tankless water heaters (99% efficiency). It comes in white colors. It has the potential of saving you up to 50% and has a digital panel of temperature control. Its stainless and copper components enhance its durability, easy replacement, and efficiency. Its size will also save you valuable space and has a stylish design that makes it more appealing to the eye. The thermal protection technology protects it from dry fire and overheating.
5. Takagi T-H3-DV-N
This water heater has an indoor installation style, and its compactness saves valuable space. It is condensing, has high efficiency, and is powered by natural gas. The gas rate is up to 199,000 with ultra-low nitrogen oxide emissions. It has a high energy conservation ability while offering an unending supply of hot water. Its safety features are computerized, meaning that you don’t need to worry about the pilot light. Such features include overheat, freeze, and surge protection. Moreover, its heat exchanger technology uses a commercial-grade alloy of copper. This allows for better heat transfer, about 25 times better than stainless steel.
6. Bosch Tronic 3000
These are also referred to as “point-of-use heaters.” This is electric, lightweight, and ultra-compact, allowing for its installation in a concealed location. The unit provides about four hot water gallons, thereby cutting down the long wait and reduces water wastage. It has been designed to offer an endless hot water supply for the bathroom and the kitchen sink at a time in residential and commercial applications. It has a 98% thermal efficiency rating. The premium glass-lined material provides it with longer service life. This feature also makes it easier to maintain.
Generally, while gas-powered tankless heaters are cheaper and efficient, they need ventilation to remove the gas by-product. However, they exhibit better performance than those powered by electricity in cold weather. Tankless heaters powered by electricity tend to be expensive, but they don’t need venting, are clean, and their efficiency is top-notch, with the majority housing an efficiency of above 96%. Similarly, the condensing types are more efficient compared to non-condensing types, which cool the gases produced externally. Overall, they all save valuable space because of their size. Therefore, buying a heater that matches your needs should be your priority when shopping for tankless water heaters.
