While tankless water heaters have a lot of perks, there can be some downfalls. But good news! Some of the newest tankless water heaters being produced are quickly fixing these problems. One concern for people who want to install a tankless water heater is that regular water heater models have input and output water lines that are on the top, where tankless models have theirs on the bottom or side of the unit. To better improve the replacement of a tank unity to a tankless unit, manufacturers are now making tankless models that have the cold and hot lines on the top of the unit.

Another worry for owners of older tankless units was the issue of inconsistent water temperatures, also known as the “cold-water sandwich”. This occurs when the hot water would suddenly become cold and them become hot again very quickly and then go cold just as quickly. Many companies have attempted to fix this problem by adding recirculation systems and adding new technologies to ensure that homeowners have a reliable flow of hot water.

Another common problem of older tankless units is that the required routine maintenance to deal with the scale buildup that caused these units to become less efficient and added to the overall cost of owning tankless units. Manufacturers listened to their customers’ complaints about this issue and have designed models that now make the required maintenance easier to deal with and cut down immensely on the scale buildup.


We have stayed on top of the tankless water heater scene since day one. These are our reviews on the brands out there that we like right now. This is by no means a complete list of available tankless water heaters, but it is our overview of our top tankless water heaters:


Ecosmart specializes in “greener” technology and is based in Florida. One of the main selling points for tankless systems is that they can save a homeowner a considerable amount of energy and Ecosmart’s tankless units shines brighter than most units. Many of their models have been known to give homeowners up to a 60 percent energy savings; however, it should be noted this is all relative to each home’s specific hot water needs. Ecosmart systems are also incredibly compact so they can be installed in a wide range of areas. The units have a “Flow Sensor” technology that is designed to make sure that the homeowner has a consistent supply of hot water.

Rinnai tankless water heaters began in 1920 so they have plenty of experience when it comes to tankless water heaters. Earlier in this blog post, we discussed some of the newer features being introduced by manufacturers of tankless water heaters and Rinnai is at the forefront of a lot of these. For example, to correct the issue of inconsistent flows of hot water, Rinnai tankless units have added a recirculation unit to some of their water heaters. The recirculation technology ensures that your water is hot when you turn it on and that it stays hot. We talked about the ancient problem of scale buildup in older tankless water heaters that hinders the units from running at peak efficiency. To help with that problem, Rinnai has added isolation valves to some of their units, which are designed to help make the required routine maintenance and descaling of the units easier.

Rheem is another manufacturer that has been around for nearly 100 years and they feature a wide line of products that will fit most any need you may have whether it’s a modest apartment or a spacious mansion. Rheem units have built-in condensing heat exchangers that allow the units to boast an impressive 94 percent thermal efficiency. Some of their units can produce up to 9 gallons of hot water per minute, which is a massive help for those residents who have cold ground water.

We will finish this review roundup with an examination of the manufacturer Noritz. Noritz is known as one of the top brands out there and that is because they provide units that attempt to eliminate just about every negative aspect of tankless units. For example, we discussed above the issue with tankless units being difficult to install in areas that previously had a standard storage tank water heater. Noritz now makes a tankless water heater that has both lines on the top of the unit making for an easier – and cheaper – installation. Noritz tankless water heaters are also very environmentally friendly. Many are made of recycled parts and materials and the company has worked hard to cut the carbon footprint of the units by dramatically reducing their carbon emissions.

In Concord, there are some definitive issues to review before installing a tankless water heaters. The first thing to check in your home is to see if you have galvanized plumbing. Our technicians find that to be a very common occurrence in Concord and, if your home does have galvanized plumbing, that could result in a much higher cost to install a tankless unit. The reason is that the plumbing would have to be replaced since galvanized plumbing can lead to major problems for your tankless unity. One complication that could occur stems from the flakes and bits of metal that can clog up the unit and cause it to fail or, at the very least, not work at optimum efficiency. Another headache that may happen is for residents of condominiums or townhouses. People who live in these types of buildings often share a common flue and that air passage needs to be checked. If it is not up to code, it may need to be renovated. Many of these condos or townhomes are managed by HOAs (Home Owners Associations) and their approval for the renovation is a hurdle to jump over before any changes are made.
