Recently, Mechanical Hub spoke with Dustin Bowerman, Director – Corporate Training and Product Support, Bradford White, regarding information surrounding gas vs. electric water heaters. The following is an exclusive Q&A.

Which type of water heater is more environmentally friendly? Why?
Bowerman: Although gas heaters have an exhaust element that most will immediately say is less environmentally friendly, you have to consider the carbon footprint of how the electricity is generated, too. Unless coming from a renewable source, there is an inherent environmental effect with both of these fuel sources.

What is the difference in cost between the two types?
Bowerman: It’s mostly about supply and demand, although there is a regulatory element. As a rule, residential electric water heaters have fewer components, therefore are less costly to manufacture; however, in some locations, regulations or codes are driving towards the use of heat pump water heaters (HPWHs).

Is there a noticeable difference in return on investment for each type?
Bowerman: Both categories offer high efficiency options, as well as specialty products such as tankless or heat pump water heaters, that can reduce utility spend while delivering the same amount or more hot water than previous models.  Though, these higher efficiency options typically come with higher maintenance costs.

Normally, a homeowner will request a replacement of what was already there. How difficult is it to change to a specific water heater source (gas or electric) if the home is equipped with only on type of energy source? (If home has only electric source for WH, what goes into gas conversion and vice versa)
Bowerman: Upgrading utilities can be fairly involved and will certainly require a professional’s experience. If converting from gas to electric, not only will a plumber be needed, but the job will require an electrician, to upgrade the electrical panel and run an outlet for an electric water heater. Converting from electric to gas may require adding gas piping to the home or updating the system to handle the additional demand. An all-electric home likely doesn’t have a chimney system, making gas water heater options more limited. Direct vent, power vent or power direct gas model would need to be utilized. Natural gas availability is also sometimes limited, so propane options may have to be considered if a home or business owner wants to stop using an electric product.

Overall, which is easier to install?
Bowerman: Water connections are the same on both gas and electric. Gas water heaters will have both a gas connection and an exhaust connection that must be done to complete the installation. An electric water heater has line voltage connections with, as a rule, three connections total.  Both should be safely installed to comply with all local code requirements by a professional.

Does brand matter more than water heater type?
Bowerman: The type of application is always important, just like having the right tool for the job. Both types of water heaters have their strengths. Of course, brand does matter. Not every water heater is manufactured to the same level of quality nor does every company provide the same level of support and customer service.

There is a lot of talk about legionella and water-borne pathogens lately. Is there one type that is more beneficial in terms of this?
Bowerman: No. Energy source does not impact the quality of the cold-water supply being delivered to the water heater.

What is the ratio of homeowners across the country using one type over the other?
Bowerman: Generally, the entire water heater market is close to a 50/50 split on gas versus electric.

For electric, what happens during a power outage?
Bowerman: The electric water heater requires electricity to heat water. If power is lost, the tank will not reheat the stored water until the power is restored. The already heated water in the tank will remain usable until depleted or gradually cool down.

Does tankless (electric vs. gas) add another layer or dimension to this conversation? Explain.
Bowerman: Yes. Conversations about tankless water heaters are common; however, in many situations the electric options are not as often considered for whole home applications. Electrical requirements may be unrealistic for many homes while gas technologies have made great advancements making tankless gas viable, using natural gas or propane, in the right installations and climates.

Is the footprint between the two (gas vs. electric) noticeable in terms of space?
Bowerman: In terms of the actual products, like gallon capacities are commonly similar diameters, using comparable footprints. Overall, space variations will be more about the gas product’s “add-ons” (e.g. blower, draft hood) due to venting requirements.

In terms of longevity, which type is more reliable?
Bowerman: National averages for functional lifespan tend to be a couple years longer on electric water heaters.

Can you talk in terms of efficiency for both types?
Bowerman: Both energy sources offer high efficiency models. If looking at base models, electric water heaters employ immersion heating elements. As these are directly submersed into the water, most of the elements’ heat energy is being absorbed into the surrounding water. Gas water heaters employ a combustion chamber that traditionally is located below the water tank. Heat is transferred through the bottom of the tank in addition to the flue(s) that is surrounded by the stored water.

This isn’t the whole story. Annual operating cost is another measurement than can be used to compare models. While these costs are largely influenced by the local utility pricing, gas models usually show less annual operating costs.  Water heaters are rated based upon how much hot water they can deliver (i.e. First Hour Rating).  Depending on their First Hour Rating, models will fall into one of four draw bins.  A model must only be compared to other models in the same draw bin, as this will impact the operating cost.

Could the decision gas vs. electric come down to how much water will be needed to heat? (How many people in the home and for what functions)
Bowerman: Infrastructure, what fuel source is available, and hot water demand are the largest variables in water heater selection and contractors need to understand these prior to making suggestions and doing installations.

Are electric water heaters safer?
Bowerman: Having your water heater installed and serviced by a qualified professional is the best way to make sure that your gas or electric fueled water heater is performing properly and safely.

Finally, why is the question of gas vs. electric so polarizing?
Bowerman: It’s due to a lack of understanding. For many contractors in the plumbing trade, electricity is not a part of their daily work, making it mysterious.  For consumers, it’s similar.  They are generally more comfortable with what they use on a daily basis and has historically worked for them.

So, as the story goes, a sales rep out west who had spent decades selling a competitor’s plumbing products is hired by General Pipe Cleaners. After initial training, he returned to his territory with a smattering of cables, cutters and drain cleaning machines to get him started.

The first time he demonstrated the Flexicore Cable, he called the company to complain that the pipe snake, “just didn’t feel right!” It felt “limp”, not “springy.”

As Dave Dunbar, National Sales Manager with General Pipe Cleaners explained, “the Flexicore engineering process has the effect of making the cable feel less springy than hollow cables.”

It took a few phone calls to get things straightened out with the rep, but then six months later, he was complaining that the cables lasted so much longer than his former brand’s that he was only selling a fraction of his previous replacement snakes. A small fraction.

It was this story that interested a few of our contractor friends. Why would it be springy? Is it really that stiff and is that a good thing? Would it really last longer?

Knowing General Pipe Cleaners would be at the WWETT Show this past spring, I introduced the General’s team to a few drain cleaning contractors that we are big fans of and have worked with in the past. It was my hope that we could create some valuable and interesting content based on the original story and the contractors having never used Flexicore.

It was soon after the show that we asked for them to send a few of their Flexicore cables to a few of our ProStaff team members to get their thoughts on the cable. They obliged and three drain cleaning pros were sent the cables to use on their existing cable machines, which for transparency, were all competitor drum machines.

As you may know, the Flexicore cable is the result of a process, where instead of coiling a hollow cable, they tightly wrap spring steel around a 49 strand aircraft quality wire rope. This provides the cable additional strength when it is under torque.

Each member of our team received a variety of Flexicore cables based on their typical daily drain cleaning challenges with the request to use them over a couple of months and provide feedback. The team of contractors included Felix Delgadillo, DrainGuys (Chicago), Terence Chan, Impetus Plumbing (Vancouver) and Jeff Keller, Bulldog Contractors (Texas), all are longtime drain cleaning professionals in their area of the country.

As expected, those daily challenges included providing both residential and commercial services, addressing clogged kitchen drains, clogged bathroom drains, clogged outdoor drains, and clogged sewer lines using today’s best technology to unclog lines to keep the water flowing.

While Keller, Chan and Delgadillo confirmed that this was the first time using the cable, Chan stated what all three mentioned, “I’ve never used the product but very excited to see what it can do.”

Chan went on to say, “Initially seeing the product, I was a bit leery how it may hold on to the heads, but it did, really well. In fact, I’ve had trouble with heads from a competitor and the Flexicore held.”

“The screws to hold on the head versus a snap lock is a nice addition,” said Keller.

One of the unique byproducts of the Flexicore process is that the cable stiffens and gets stronger under torque, which Delgadillo agreed, “the cable feels less springy and it does get quite stiff when the operator needs it the most.”

Keller continued, “it caught me off guard and took some getting used to. Most if not all drain cleaners/plumbers are used to listening to their machines and the feel of the strain on the cable to evaluate the blockage, so this was a bit different, but did a solid job.”

As discussed in the WWETT video, when a drain cleaning machine rotates a pipe snake down the drain and it hits a clog or stoppage, tension or torque builds up in the cable. Because of the direction the drum is turning, the reaction of the outer coil of spring steel is that it wants to contract due to the tension. However, because the wire rope is in the way, the only thing that it can do is tighten, which makes it stiffer and stronger and the cable much less likely to kink or break when in use.

Chan concluded, “I would recommend this to peers in the field as it got the job done. I’m curious to see the long-term difference versus some of the cables we typically use and recommend everyone make sure they have the cable sizes they need for their machines.”

We second that Terence! Be sure to size your cables correctly so it all works perfectly.

While the contractors are still using the cables in the field, it was a unanimous decision that more time in the field was needed to truly understand the value of Flexicore cables and how it holds up long term versus other options.

We will continue to check in with the team to provide updates later in the year.

A new life.

Nicholas Verkhoturtsev’s story starts in his hometown of Ural—everybody calls it Siberia—Russia. In 2002, Nicholas graduated from Law State University with a Bachelor’s degree. That same year, a company Nicholas worked for as a lawyer, purchased a plumbing company and Nicholas became co-owner of that company.

Teaching law at the University and working on his Master’s degree seemed to be the career path he set for himself. “I didn’t do anything in that plumbing company; I just controlled its finances, but I paid attention and learned their work, skills and knowledge,” says Nicholas.

In the meantime, with increasing corruption in Russia, Nicholas became disenchanted and bored with law so he turned to plumbing. “I got interested in plumbing because I liked it as a field where everything depended on my skills and knowledge, not on other people—judges, prosecutors, government people etc.—or how much money I bring them under the table. Yes, I would make more money if I stayed in law, but I fell in love with plumbing because of that independence,” says Nicholas.

He created a plumbing company and hired the guys from the company he controlled previously. “I continued to learn their plumbing skills and did all paper work and management of operations. In 2003-2004, I started to do all work myself and fired the guys who worked for me. Most of my jobs in Russia was residential, but I did some big projects such as a water park—the radiant heating system with mixing and pump units, used 18 miles of PEX pipe—an auto dealership—radiant heating system with climate control, for example,” says Nicholas.

Nicholas soon realized that growing and developing his plumbing business looked grim, and any outlook for making his family’s life better looked increasingly bleak, “because of huge corruption, a sputtering economy and terrible politics by fucking Putin and his people,” says Nicholas.

What was supposed to be a planned vacation to the United States turned out to be a lifetime commitment. “I tried to change things by becoming a peaceful political protester in my home city, but with very bad results. I ultimately decided to move to the U.S., got all of the necessary documents, and did it.”

Upon arriving in the United States, Nicholas worked for David Hesson, and for the past five weeks has been working for Robbie Mann at A. Mann Plumbing LTD, Centerburg, Ohio, as a tech for residential and commercial plumbing and hydronic heating systems, service plumbing and drain cleaning. “I am very happy to be a part of their team,” says Nicholas.

While growing in the trades and starting his own plumbing business in Russia, Nicholas didn’t have any mentors, really. But, according to Nicholas, “I would call Eric Aune a friend and mentor; I learned a lot from him on Instagram while I worked in Russia.”

Now in the states he’s learned from Hesson, and his current teachers and mentors, Robbie Mann and Mark Starkey. “Every hour, every minute when I work with them I gain knowledge and skills. And, they always answer my stupid questions,” jokes Nicholas.

The Next Generation

Nicholas does express concern about the future of the trades. “I don’t see many young people who are ready to grow and learn things in plumbing, here is the USA and Russia.” And, from what Nicholas has seen is that plumbing in America is always growing. The importance of the trades has never been more evident than in these uncertain times of the pandemic. “After fucking Covid starts, we are getting more service calls. Covid just proves plumbing is as necessary ever,” says Nicholas.

“We all need to reach to people, young people and make them able to realize that plumbing is an essential job, a necessary job, and that people can’t live without water, heating and waste management.”

Nicholas’s advice to those entering the trades? “Learn everything yourself; learn more than you should know. When you start to work in plumbing, do more than you should do and don’t wait for someone to give you skills and knowledge. Just get all this yourself.”

Me Time, Social Media

In his spare time Nicholas continues to learn plumbing, and he reads American plumbing codes. As well I do some exercises on my knees and back. That is what plumbers need. And, according to Nicholas, balancing family/work life is sharing every concern, every thought, every action about your work with your spouse. Your family should know every detail of your work life. “In my opinion, it helps find necessary time for your family.”

Social media has been instrumental in Nicholas’s growth, as well. He has found many of his current friends in the states on the social media platform. “A couple of my best friends from Instagram are Eric Aune and my boss Robbie Mann. Eric has always supported me, and when I arrived in the U.S., he sent me a bunch of tools which I’m still been using every day,” says Nicholas (@installer.nicholas). “I think Instagram is the best network to share work, knowledge and skills. And sharing these things is a way to find people who understand you totally.”

The last time Nicholas said, “Today is a great day”? It’s hard to say, says Nicholas. “In plumbing I enjoy results done perfectly; when everything is perfect, especially systems water flow and efficiency. Sometimes I even lose time/money to get something perfect, but I do it to enjoy the result … to enjoy my life, finally.

Imagine threading or welding 4″ carbon steel pipes, 40 feet in the air. Sounds difficult, time-consuming and potentially dangerous.

All those pitfalls were avoided when a crew in Michigan used Viega MegaPressG fittings to pipe a new bean-roasting facility. The result was clean, attractive piping, a quick turnaround on project time, plus happy workers and owners.

Viega recently added MegaPressG fittings in sizes 2½” to 4″ to its lineup, and Schreiner Mechanical out of Frankenmuth, Michigan, was the first to install them, putting a couple dozen of the larger-diameter fittings into a new build in Gilford.

The project that Steve Schreiner, owner of Schreiner Mechanical, and his crew went to work on was a soybean-processing facility. The soybeans are roasted and crushed, then the oil is removed and used for biodiesel fuel and other applications. The remaining product is used to feed dairy cattle, leaving zero waste.

“What the plant does is unbelievable,” Schreiner said. “It’s favorable to the economy, and the oil can be used for several different products. There’s no waste.”

At first, Schreiner Mechanical was asked to do some plumbing in the office of the plant. Then the project, and need for Viega fittings, started to grow. The contractor was tasked with creating a gas main and system
to supply the gas for the burners that roast the soybeans, plus they needed to plan for the plant’s future growth.

“The burners that are used are about 12 million BTU each, so they needed a high-pressure gas system in the plant feeding these machines,” Schreiner said. “That’s quite a large capacity, and in the future they’ll potentially have three more of these burners, so this gas system had to be designed to feed a tremendously large system.”

To do that, Schreiner Mechanical created a manifold with 4″ gas lines. Those lines work their way down to 2″ in size throughout the plant. It was the perfect place to put MegaPressG in larger-diameter sizes to work.

“Lines run throughout the plant for gas feeding the furnaces and rooftop units feeding other areas of the building,” Schreiner said. “There is probably about 500 feet of gas line with Viega fittings in this building.”

Schreiner will tell you he is “a Viega guy,” and when he began working on this project he was excited to hear that MegaPressG fittings in the larger sizes were on their way to market. 

“If we’d had to thread this, it would have changed the whole philosophy on how to do things,” Schreiner said. “It would have made things 10 times more difficult, being 40 feet in the air, so we would have had to change the installation, plus it would have tripled or quadrupled the labor intensity. We’re talking about lift rentals and all things that come into play, plus the costs incurred for that, if we’d done it a different way than pressing. Threaded pipe would have been absurd.

“I’m excited that by using MegaPressG on this project, it was a time saver, a labor saver and safer than welding. The injury factor that can come up with different products is much bigger than with pressing. We would have had guys on the ground cutting and pre-fabbing pieces and then going up and down, but pressing in the air is much easier.”

In addition to providing the gas to the burners for the roasting in the plant, 2″ carbon steel lines with MegaPress fittings were also used for the oil line, moving the extracted crude oil from the beans into tanks.

Schreiner’s team is set up with Ridgid tools, and he said he feels that Ridgid and Viega together are the perfect combination.

“The Ridgid tool was a huge part of this successful application,” he said. “I’m passionate about the products I use, and when I find a good one, I stick with it.”

Viega District Manager Mike Norgan brought out the MegaPress XL PressBooster tool for Schreiner’s crew to use on the larger-diameter MegaPressG fittings, and Schreiner said it was simple to use.

“There was nothing more than smiles after using the tool,” he said. “Along with the large-diameter rings, it was easy and not cumbersome to use. Being able to press 12 or 14 large fittings in less than an hour is unbelievable.

“I tell people, ‘Look at what can be done [using Viega products]. This can be you and it’s this easy,’” he added. “Everybody’s hands are clean, there are no contaminants in the system, and there’s a lot to be said about that, having a contaminant-free system. When you have solder or threading oils or shavings, you have a high chance of contaminants, but with Viega, that chance is zero. I just cannot say enough about Viega. What we accomplished on this project with it is amazing.”
