When you’re searching for a new water heater for your home, the Noritz NRC661 can be a great option and a system that’s a total steal for the price. This water heater is able to keep up with a small family’s water demands, which is a huge plus for any family that’s tired of fighting over who gets to take a hot shower first. It’s also considered very energy efficient, so it can save you some money on your utility bill each month.
Overview and Features
Noritz is a company that has a reputation for producing lower-priced tankless water heaters that are moderately powerful. There’s always a tradeoff when it comes to a lower price tag. With this model, it involves the ability to heat up enough water for a larger home. However, this water heater still has plenty to offer the small family on a tight budget.
Before you buy, keep in mind that with this type of water heater, you’ll need some type of venting system. If you have regular PVC piping, you’ll be able to hook the venting to this and you’re good to go.
This model is a condensing, gas-fired, tankless water heater designed for small homes. It has a 0.2 gallon holding capacity and weighs in at just thirty-eight pounds. This model can heat up water on demand using natural gas, but it has an electric ignition, so it requires electricity as well. This tankless water heater features basic temperature controls, however, you can also purchase the optional remote control complete with a digital display. The heater utilizes a direct vent kit that’s made from CPVC or PVC pipes, and a non-direct conversion kit is also available if you want to mount the tank on a non-exterior wall.
This water heater is considered moderately powerful and it’s still a major step up from a traditional water heater.
In total, the water heater will consume fifty-four watts of electricity. However, electricity consumption will increase to one hundred and thirty-eight watts when you switch it to the anti-frost mode.
You can also rig the heater’s battery backup in order to use it during a power outage, in addition to connecting it to a wall outlet. It has an energy factor of 0.91 which is on the high side for a gas-powered model. Whether you use it with propane or natural gas, it’s also ninety-three percent efficient. This model features low nitrogen oxide emissions, but it doesn’t meet the industry’s standards.
This is a durable compact, space-saving model.
Inside the water heater, you’ll find a couple of heat exchangers that are made out of copper that’s commercial grade and said to be twenty-five percent thicker compared to the regular copper that’s used in a gas-powered tankless model. Both heat exchangers are covered by a twelve-year warranty. In order to improve durability, the manufacturer has also included some great safety features such as a temperature control lock, condensate overfill detector, fan rotation detector, freeze protection, lightning protection device, overheating protection device, and a flame sensor.
Gas consumption ranges from fifteen thousand up to one hundred and twenty thousand BTUs per hour. Basically, the burn rate provides a minimum of 0.5 GPM hot water flow rate with a max of 6.6 GPM. The water heater is able to deliver its peak flow rate with a water temperature increase at thirty degrees but can only deliver half that flow rate with a seventy-degree increase.
Considering the water heater’s flow rate ability, this model is only able to serve two faucets or showerheads at once. It can’t compete with the Stiebel Eltron 29 PlusTempra Tankless Water Heater, which is designed for larger households but comes with a higher price tag.

During the colder months of the year, the water heater will only be able to provide one shower head with hot water. The water heater can heat water to temps that range from one hundred up to one hundred and forty degrees, but you’ll only be able to choose a few temperatures for the heater itself. The optional remote will allow you to select from a total of nine temperature settings.
This is a model that’s designed for a small family. While it does burn gas efficiently, it also draws quite a bit of electricity. It’s barely able to provide enough water for two faucets or showers running at the same time.
With ongoing tankless water heater maintenance, the manufacturer claims this model can last for up to twenty years, however, the warranty only covers this model for twelve years.
Like with all other models of water heaters, this installation can be a little complicated. If you don’t have much experience with water heater installation, we recommend consulting a pro.
