Noritz Blog 2 | September 2018

The company received awards for two products that created efficiency and innovation in the industry.

Noritz strives to create water-heating solutions that are effective, efficient and easy to install for plumbing and HVAC contractors and building owner-managers. This year, our company had the distinct honor of receiving two awards for products that excelled in their innovation, design, and functionality.

• The NRCB Residential Combination Boiler was recognized by The Architect’s Newspaper as a winner in the publication’s annual “Best of Product” awards competition.

• The NCC199CDV Condensing Tankless Water Heater was given the Bronze Award in the Plumbing and Water Management sectors in Consulting-Specifying Engineer’s “Product of the Year” competition.

NCC199CDV: Simplicity and efficiency

As a 2018 Product of the Year winner, the NCC199CDV was recognized for its innovation in heat safety and ventilation. Installers can common-vent up to six units, reducing the number of through-the-wall vent terminations and the necessary supports to install them. This capability allows for long vent runs and a cleaner aesthetic than individually vented systems.

With an industry-high thermal efficiency unit of 98%, the NCC199CDV is ENERGY STAR® certified. The unit has a maximum output of 199,900 BTUs per hour and includes two austenite stainless heat exchangers that resist corrosion, maximizing its lifespan and durability. Up to 24 of these heaters can be linked together, offering the most control options in its category.

NRCB:

With a performance that meets “Energy Star Most Efficient” standards, the 95%-efficient NRCB Residential Combination Boiler allows simultaneous residential domestic hot water and space heating, an industry first.

Unlike traditional combination boiler systems, the NCRB’s simultaneous capabilities are easy to control and help applications that cannot store or deliver heat energy effectively.

The unit also uses 316L austenite stainless steel heat exchangers, which enhance its durability and lifespan. For space heating, the unit has a temperature range of 80°F to 140°F; for domestic hot water and a range of 90°F to 140°F.

The NCRB provides nearly twice as much flow as other competitors, ranging from 9.8 to 11.1 gallons per minute. The flow valve – not offered on competitor models – will ensure a consistent temperature for domestic hot water, regardless of incoming water temperature.

The product also offers various user and installer-friendly features:
• It is compatible with recirculation loops without the need for additional accessories.
• The mounting bracket aligns with the unit’s top, allowing for easy positioning on walls.
• On top of its compatibility with the Noritz Connect Wi-Fi application, it weighs less than 100 pounds, making it lighter than traditional boilers and saving close to 80% in space during installation.

California contractor has tankless as his go-to wherever possible

Edward Asuncion has been a certified plumber since 1991 and has owned his own business, Bonafide Plumbing, in Alameda, California, since 2007. Although not always a proponent of tankless water heating technology, the past few years have seen a shift in his thinking.   
“Until five years ago, I was hesitant to install the technology, because I was worried about having to upsize the gas line,” he recalls. “I eventually discovered that, in many cases, a Noritz unit allows me to keep the same gas line.”
Since then, Edward has never looked back, now installing, on average, one tankless unit per month.
He works in a unique part of the country. Alameda has a dense concentration of single-family Victorian homes, which makes for interesting history and architecture, but difficult plumbing.
“Not only do I have to convert the plumbing pipe from galvanized steel to copper when installing a new water heater, but the old heater is often positioned in the middle of a room,” he explains. “So, to save space, we try to relocate the new water heater to the wall.”
Moving the heater is much easier with Noritz units than a storage tank — or even other tankless models that are heavier, according to Edward. Because of their compact, lightweight design, they are easily wall-mounted and offer more than enough space for maneuvering around and routine dusting.
Tankless Case-In Point
Edward recently finished installing an NRC711 in a Victorian home for a family of four. The previous, 50-gallon storage tank water heater had pilot light issues and wasn’t providing the necessary hot water.
Edward gave the homeowners an option between tank and non-tank. “I emphasized the space savings for this family. The unit could be installed outdoors, giving them extra room inside.”
He also discussed the ability to enjoy unlimited hot water, thanks to the unit’s powerful burner that quickly heats incoming water. “I told them they can run hot water all night if they want, as long as they pay the bill,” he laughs.
Finally, he mentioned the potential energy savings. “Since the unit heats water only on demand, it doesn’t need to constantly turn on and off, burning energy when no one is home,” he explains. Depending on the type of unit being replaced, a Noritz can save up to 40 percent in energy costs.
The 41-pound unit was easy to move and wall-mount, so the installation went smoothly. As with many other older homes in Alameda, much of the plumbing had to be upgraded, but the compact nature of the NRC711 streamlined the job.
Edward says he will continue installing Noritz units, especially since he’s never had a single call-back. “I’ve installed several units over the past few years without any complaints or malfunctions,” he says. “That’s reason enough to stick with this reliable technology.”

Inspecting and maintaining your plumbing components (exposed pipes, toilets, sump pumps, and even tankless water heaters) is crucial to your peace of mind after the long winter.

Step outside and enjoy: The weather is warmer, the sunlight is brighter, and the sounds of birds and insects begin to fill the air. Spring is here and with it the promise of outdoor strolls, family picnics and late-night talks on the porch with friends.

With the snows a distant memory, revealing the grass and sprouting plants, it’s also a critical time to check your indoor and outdoor plumbing for winter damage. This is especially true after the long, frigid and snowy season much of the country experienced.

Here’s a short checklist:

Check outdoor pipes: Start outside and work your way back inside. Debris can collect over the autumn and winter and clog outdoor drain pipes. Make sure to clean them out completely. Also be sure to clear your roof and gutters of debris so those spring rains can easily drain.

Check for pipe cracks: This goes for both outdoor and indoor piping. The winter cold can cause water to freeze and expand inside your pipes, in turn causing them to crack and leak. Identify and fix these cracks as quickly as possible to prevent further damage. Another way to check for cracks indirectly is by turning on your faucets and making sure the water flow seems normal. If the pressure seems low, there might be a leak somewhere in the system, in which case it’s time to call a plumber.

Check your water heater: Whether you have a tank or tankless unit, spring is a good time to perform an annual inspection and flush out your water heater. Certain units, such as Noritz condensing tankless water heaters, have built-in freeze protection technology, but it’s still advised to open the cover and check for any cracks or leaks.

It’s also important to descale your water heater — especially if you live in a hard water area — to eliminate scale buildup that can decrease operating efficiency. Although it’s possible for savvy homeowners to descale a water heater themselves, a plumbing contractor should be brought in if you have any hesitation.

Check your sump pump: This is one of the most important parts of your plumbing system to check during the spring season, especially once those April showers roll in. Check the drain that runs outside for any debris. Then make certain that the pump hasn’t tilted or the float valve moved out of place. Finally, be sure to inspect the electrical components for damage.

Check your toilet for leaks: There’s an age-old test to see if your toilet has a leak. Drop a food dye tablet into your toilet tank. After 15 minutes, check the toilet bowl for any colored water. If you see the dyed water creeping in, you have a leak and need to call a plumber.

Completing this five-point checklist will let you enjoy the upcoming warm season without having plumbing problems on your mind.

After spending nearly 20 years trying to heat his 5,000-square-foot Victorian mansion, Glenn Giaimo has found a comfortable, energy-efficient solution in a combination tankless unit from Noritz.

Victorian mansions are an awesome sight to behold and could easily be considered America’s very own “castles.” Yet, when actually living in one, there can be a significant trade-off: The high-ceilinged, drafty interiors can get really cold.

That, at least, was the experience of Glenn Giaimo and his wife when they first moved into a 5,000-square-foot Victorian home in Ferndale, CA, in 1997. Built in 1901, the home’s single-paned glass windows and lack of wall insulation made for a chilly experience at times. Improving heat retention was financially unfeasible; e.g., making the thousands of window-glass pieces double-paned.

Thus, the first 15 years of the Giaimos’ residing in the home became a constant battle to heat the place effectively. Initially, a combination of pellet stoves and a forced-air furnace couldn’t provide the desired warmth. In 2000, Glenn special-ordered 34 radiators to try hydronic heating. However, frequent failures and monthly, propane- fuel bills of upwards to $1,000 during the cold season led the Giaimos to abandon this option, too.

It seemed like nothing could do the job. The Giaimos were literally relying on electric heaters and extra blankets when Glenn discovered the CB199 Combination (Combi) tankless water heater and boiler from Noritz. The dual unit was much more affordable than his other option—solar heating, which would have cost more than $20,000 to install.

A Natural Fit

The Combi unit fits right into the Giaimos’ expensive hydronic setup from 2000, which had lain dormant for years. Glenn compared the Combi’s installation to a “miraculous heart transplant” that brought the 34 radiators back to life. The unit was installed by Fred Patterson of Patterson Sales Agency Inc., the local sales representative for Noritz, and a licensed plumber.

The new Combi boiler also fed the domestic hot water (DHW) heating system, which had previously been served by a 50-gallon storage-tank heater. Although the Giaimos had no problems with water heating, this switch was an added bonus. Removing the old tank saved space, as well as eliminated the energy-wasting need to constantly heat the stored water.

The Combi is able to convert 95 percent of the fuel it consumes into useable heat, which was crucial for the Giaimos’  situation. The home’s astounding level of heat loss was always the main reason the family had struggled to keep it warm in a cost-effective way. In addition, the home’s being on the National Historic Registry made it difficult, if not impossible, to reduce heat loss to the outdoors without altering the aesthetics of the original stained glass and clear windows.

Post-installation, and within an hour of turning on the unit, Glenn reported his first-floor set point temperature had already been reached. He also put the unit’s outdoor temperature reset control to use. Installed outdoors, the control measures the outside temperature and automatically adjusts the unit’s output to keep the interior warm. A hot-water recirculation system Glenn had installed provides nearly instantaneous hot water on the DHW side, even to the furthest fixtures.

Super Savings

For the Giaimos, who had been spending $6,000 during the six cold months of the year on propane for the stainless-steel boiler and, later, roughly $350 per month to power his multiple electric heaters, the Combi unit’s efficiency made a huge impact on energy costs. Glenn reports that he now spends around $80 per month on propane, and another $80 per month on his electric bill, for an 88 percent total reduction!

Based on his experience, Glenn believes that other historic homes lacking insulation can benefit from the Combi, especially if they have hydronic heating systems already in place. Finally, 20 years after moving in, the Giaimos have found a system capable of heating their Victorian mansion.

2017 Model Remodel home includes direct replacement tankless water heater

for ease-of-installation and energy savings.

Each year, the Model Remodel program takes a home in serious need of a makeover and turns it into a modernized, energy-efficient residence. This year, the project was a 1,300-square-foot home in Woodbury, Conn., in which the owner wanted to spend the rest of her life.

Built in the 1930s, the single-level home was completely gutted to add a slew of maintenance-friendly designs and appliances to keep the homeowner’s long-term expenditures affordable and consistent, assuming a fixed income.

Answering the hot water question

One of many decisions that had to be made from an energy-efficiency standpoint involved replacing the home’s 60-gallon storage-tank water heater.

To simply swap it with another storage-tank heater didn’t make any sense in the context of the project’s energy efficiency goals, as it would consume energy all day and night, regardless of hot-water demand.

Instead, Ben Bogie, general contractor at Built to Last Design & Build LLC, immediately identified tankless water heating technology as the preferred solution. “Our firm has been installing predominantly tankless heaters for the past 10 years because they’re great from a cost and stewardship perspective,” he says. “They fire only on-demand to give you hot water exactly when needed, thereby saving energy.”

Replacing a storage-tank water heater with a tankless model has traditionally brought installation challenges beyond draining and hauling out the massive tank. While storage-tank heaters have top-mounted hot and cold water connections, conventional tankless units have those same connections on the bottom. Thus, contractors usually have to add extra plumbing to lengthen the connections, raising material and labor costs.

EZ as Pie

The Model Remodel contractors chose the EZTR75 tankless water heating package, which Noritz donated to the project, for a streamlined installation.

The EZTR75 is a direct replacement option for 60- and 75-gallon storage-tank water heaters because of its top-mount water connections and multiple venting options, which reduce installation costs. The package comes with an EZ111 tankless water heater, a flex vent conversion kit (with 25 feet of 2-inch flex) and an isolation valve kit. Venting can be accomplished using either dual-pipe or single-pipe (made of PVC or CPVC), as well as the included 2-inch Flex, which can be fed through the existing B-Vent. Once again, these venting options save time and material.

“It’s 100 times easier because you’re not piping down to the bottom of the unit to connect the water lines,” says contractor Bob Lucas, owner of Lucas Plumbing LLC. and the installing contractor on the job.

Lucas was able to install the EZ111 in under three hours. For venting, he ran the 2-inch Flex included with the unit up through the existing B-vent. The simple venting and top-mount water connections were major time-savers. The streamlined installation saved an estimated $300-$400.

Overall, Lucas reports no challenges on the installation. “It was really straightforward. I can’t emphasize the importance of those top-mount water connections enough. Other tankless units don’t have them, and are therefore a hassle to install.”

Creating a sustainable future

Since the installation, the unit has been tested and forecasted to earn the homeowner significant energy savings once she moves in, especially when considered in the context of the entire remodel. Other energy-efficient features include low-flow showerheads and faucets and triple-glazed windows. Thus, while the tankless water heater promises substantial energy use reductions by itself, when combined with the rest of the home, it helps create a truly sustainable environment for the long-term future — perfect for someone planning to spend the rest of her life there.
