Air-Tec, one of our HVAC product lines, published a recent newsletter with some information we thought our customers would find valuable on the benefits of a pre-fabricated engine exhaust system. Here it is:

“Chicago customers are finding that the modular pre-fabricated engine exhaust system is their new choice over the old black schedule 40 installs to gain control and reduce the costs of your next emergency generator install. Why?

In material list alone, a pre-fabricated engine exhaust system sees an average 15-20% cost savings compared to the schedule 40. The costs for each system included inner pipe, insulation, outer jacket, bellows, fixed and guide supports.

But the much bigger savings were found in the labor costs. The modular pre-fabricated system is simply that. It comes in 304 stainless steel, 1”, 2” or 4” wool insulation and galvanized outer jacket ready to install by one trade. The outer jacket is also available in 304 stainless steel for harsh conditions or for the portion of the stack exposed to weather. In all cases the black schedule 40 pipe took considerably more time to complete each connection, suspend from the structure, was harder to handle, still needed to be insulated and then the galvanized jacket applied requiring three trades.

The logistics of scheduling the other two trades was also another consideration that was brought up several times.”

Since the material cost offers a considerable savings and the install time is typically done in less than half the time requiring only one trade, you can see the benefits of a pre-fabricated system.

All heating equipment needs maintenance in order to operate in peak condition. Do you offer a service to take care of your customers’ boilers, with a regular maintenance program?

If not, you should. Boilers, like cars or any other mechanical devices, are subject to wear and tear. They need adequate maintenance, to ensure that they don’t break down because if they do, it’s guaranteed NOT to be at a convenient time to repair it. Waiting until something breaks down before repairing and maintaining it, always ends up costing you far more money, unhappy residents, higher labor rates, etc. because it’s usually during peak service demand, or in the middle of the night, or on a weekend. Usually, you end up in scramble mode trying to fix a problem that could have been avoided with regular care.

Providing regular maintenance programs to your customers, is also a good way to build long-lasting customer relationships and add a consistent revenue stream for your business.

Annual maintenance and monthly water quality checks can prevent premature malfunctions and potential boiler breakdowns caused by poor water quality, leaks or water pressure. Any boiler’s functionality can be easily compromised and impact energy efficiency which creates a large bill for your customers.

So, what are some best practices to keep boilers operating in peak condition? Here are 8 annual maintenance steps from Patterson-Kelley to help maintain energy efficiency and extend the life of your customers’ boilers.

  1. Replace all parts affected by wear and tear, every year!

Your annual maintenance kit should include all parts that need to be replaced, including gaskets to re-seal the combustion inspection covers that were removed to clean the fireside. We offer a P-K annual maintenance kit that includes all parts you need for this. Give us a call for information and pricing to get yours.

  1. Inspect the fireside of the heat exchanger

After 2,500 hours of operation, or at least once a year, you should inspect the fire-side of the heat exchanger. You can access the fireside by removing the inspection covers. Any fireside fouling should be removed by using clean out tools and water washing the fireside surface. A thin coat of mineral oil can be used on an aluminum boiler to help minimize potential fouling in between annual maintenance checks. Verify that no debris came loose and fell to the bottom, potentially clogging the air path.

  1. Remove the burner, thoroughly wash and clean the mesh

This should be done even if the burner appears to be clean. After washing the burner; reinstall it and use the fan test option to blow dry the burner. DO NOT fire the burner while wet.

  1. Replace old igniter, flame rod and gaskets

These parts are included in your maintenance kit. It is important that you DO NOT reuse old gaskets.

  1. Select the righT Water Treatment to Prevent Scale

Water side scale is equivalent to having a thin film of insulation between the furnace gases and boiler water. It can drop a boiler’s efficiency by as much as 12% – 21%.

  1. Re-start the equipment and adjust combustion using a calibrated analyzer

A water tube manometer will be necessary to check for proper draft readings.

  1. Inspect electrical connection for corrosion

Condensation can cause corrosion on the electrical connections of a boiler. Check for broken or cracked fusers and replace anything that looks questionable, then test the unit. It is also important to ensure that the electrical connections are tight.

  1. Clean the condensate trap

Once again, the condensate produced by condensing natural gas boilers is corrosive. The condensate trap must be cleaned annually and inspected for potential leaks.

A commercial hybrid heating system can be the perfect option for your next boiler room upgrade. In this latest blog post from Patterson-Kelley, “Commercial Hybrid Heating Systems, Explained in Less Than 700 Words!” you’ll see how a hybrid heating system can help you save money on your initial investment, while still operating at the highest levels of efficiency.

 

Commercial Hybrid Heating Systems, Explained in Less Than 700 Words!

Eventually, all commercial heating systems need to be replaced – and whether you replace one unit, or five, it will require a significant investment in time and money.  In upgrading your system with the latest technology can offer in condensing equipment, high system efficiency, building management and connectivity, the cost to retrofit your boiler room can escalate quickly.

Fortunately, there is an additional option. You can choose to update your boiler room while saving on installation cost and optimizing your heating system efficiency by considering a hybrid system approach.

 

What is a Commercial Hybrid Heating System?

Hybrid systems consist of one or more condensing boilers, combined with one or more non-condensing boilers that perform the same function. It is designed to both, accommodate building loads, and provide instant savings on the cost of installation.

The design of a hybrid system is calculated to handle the building load with the condensing boiler(s) until it can no longer condense or maintain high efficiency levels. Condensing boilers are more efficient when maintaining lower temperatures and lower percentage of boiler modulation (1-50%). Once they begin exceeding certain parameters, they become less efficient.

In a hybrid system, the temperature required to heat the building on a given day would be used to calculate the building load and size the unit(s) accordingly. For example, an engineer would select a specific building and calculate the energy required down to a specific outdoor temperature without exceeding 150°F boiler temperature. When the system calls for 150°F and below the condensing boiler will run, but when the system calls for 151°F or above the non-condensing boilers will kick-in to accommodate the load. This is assuming that the system will operate at a 30° delta T, so that the return temperature is at 120°F to 130°F. This will cause the condensing boiler(s) to provide high efficiency to the best of its capacity.

 

Proper Control of a Hybrid Heating System

Applying the right control to a hybrid system design is extremely critical for proper boiler sequencing, and to attain the most condensing run-time during boiler operation. The end user must be able to prioritize the start sequence of the boiler system. In the case of mild weather, the condensing boilers must have priority in satisfying building load requirements. When the weather changes, and the outdoor temperature drops below the point of boiler condensation (90%+ efficiency), the control should engage the non-condensing boiler(s).  At this point the difference in efficiency between the two types of boilers should be about 1-1 ½ %. The condensing boiler will now be operating at 88%, while the non-condensing boiler operates at 86.5-87% efficiency.

 

Why Install a Hybrid Heating System?

The benefits of installing a hybrid system include increased savings on installation costs and maximized efficiency. A non-condensing boiler can be about 40% more cost effective than a condensing boiler. When replacing a multi boiler system, purchasing a multiple condensing boilers can become more expensive than a combination of condensing and non-condensing boilers.

 

Prevent Challenges with a P-K Hybrid System Solution

Lacking a good boiler control system that can effectively manage the boiler input based on the temperature requirements of a building can become a great disadvantage when setting up a hybrid system. In which case, the building loads would need to be calculated in a way that a portion of the boiler plant will be condensing and the other portion will not be condensing.

In the past, setting up a hybrid system could have been intimidating for both the system designer and the installer. Those times are over! With recent boiler technology breakthroughs, controls are now able to achieve boiler sequencing and manipulate loads based on the type of boiler and temperature requirements.

The Patterson-Kelley NURO® Touch-Screen Control has the flexibility to control hybrid system applications. Just with one click within the settings option, the control can walk you through the easy steps of setting up the appropriate parameters. Even if the boilers are connected to a building management system, properly setting the hybrid system with the NURO® control can be a piece of cake!

We all know that designing an efficient heating system is essential for your clients. So, we wanted to share a recent post from one of our top product lines, Patterson Kelley where they take a stand on the debate between variable primary or primary secondary piping and even offer a third, new option with their NURO® Touch Screen Control System.

 

Hydronic Boilers Piping Arrangements

Just like we would debate over sports, music, or politics, engineers have long held strong opinions about piping arrangements for hydronic heating systems.  Which is better:  Primary-Secondary or Variable Primary?  They each have their benefits, but most boiler manufacturers tend to side with Primary-Secondary.  Wouldn’t it be nice to have a different choice?

What is a Variable Primary Piping System?

In Variable Primary piping systems, there is one set of system pumps, generally piped in parallel, that distribute water through the heating equipment and terminal units.  Heat generated by the boilers is sent directly to the terminal units.  A Variable Primary piping arrangement can result in lower initial costs due to the installation of fewer pumps, less piping, less electrical, etc.  Variable Primary systems are generally considered to be more energy efficient. This is based solely on the concept that fewer pumps use less energy.  For any given installation these assumptions may or may not be true, but they are accepted when choosing between Variable Primary and Primary-Secondary piping arrangements.

What is a Primary-Secondary Piping System?

The Primary-Secondary piping arrangement includes two sets of pumps, system pumps and boiler pumps.  The system pumps distribute water to the terminal units and the boiler pumps circulate water through a loop that serves the heating equipment only.  The two piping systems are decoupled through what is commonly referred to as a “zero pressure bridge”, which hydraulically separates the boiler from the system. Traditionally, Primary-Secondary piping arrangements have meant full flow in the boiler loop and variable flow in the system loop.  Manufacturers tend to prefer Primary-Secondary because it ensures proper flow through the boiler.  Although a few manufacturers have boasted “Zero Flow” capabilities for their boilers, engineers know that no flow means no heat transfer; this begs the question, “why is the boiler firing?”  Engineers have begun to shy away from Primary-Secondary due to the perceived excessive pumping energy; but is that really the case?

A Third Option

With the advancement of on-board boiler controls like the NURO® Touch Screen Control System, there is now an additional option: Variable Primary-Variable Secondary.  The NURO® can vary the speed of your boiler pump, equipped with either a VFD or EC motor. As the boiler firing rate varies, the pump speed and flow adjust accordingly.  It’s the best of both worlds; flow rate ensured through the boiler, and energy savings associated with variable flow.  One might argue… “what about installation cost?”  Yes, there is slightly more piping associated with a Variable Primary-Variable Secondary piping arrangement, however, the installation cost is not significantly more.  Variable primary systems require a two-way control valve on each boiler to prohibit flow through an unfired boiler.  A boiler circulator with an EC motor is marginally more expensive than the control valve.

We are happy to announce that Pat Tucker has joined the Mechanical Equipment team as a Sales Engineer.

Pat has a long history in the commercial HVAC business. He started with a pipefitter apprenticeship right out of high school and was able to work his way up the ranks quickly in each of his positions. He became the Piping Superintendent at Murphy & Miller in Chicago, supervising apprentices, journeymen and foremen for ten years. He was also recognized as the youngest superintendent in Local 597’s history!

He then went on to become the Piping Manager at Westside Mechanical Inc., which added more responsibility and also allowed him to use his managerial expertise. Pat’s track record of success made him a highly sought-after person, and he was soon hired as a Project Manager/General Superintendent at International Piping Systems. That’s also where Pat met his future wife, June, who is now a Vice President at F.E. Moran, and where he also met Dennis at Mechanical Equipment. Pat also began attending night school at IIT, to obtain his mechanical engineering degree.

Eventually, Pat was offered an opportunity on the supplier side of our industry, becoming a Vice President at Flomech in Downers Grove, IL. Pat was responsible for overseeing estimating, sales, design, installation and start-up for all heating and cooling projects. His experience in contracting, gives him a great perspective of our customer’s needs, helping him offer excellent customer service. Pat’s design and installation background helps assure a smooth and profitable job for our customers.

Pat shared, “Coming from the contractor side to the vendor side, I made a commitment to be the vendor that everyone wanted to deal with. I always give 100% effort. I pride myself on that and I respond to my customers as fast as I can, 24/7 no matter the size of the order or how busy I am. Business is all about relationships and I plan to continue my excellent relationships for years to come.”

Dennis O’Shaughnessy, Mechanical Equipment’s founder, said, “I was excited to bring Pat into the ME team because Pat offers our customers yet another source for our ‘best in the industry’ customer service. His knowledge and design expertise is an invaluable asset in making sure that we are performing and delivering better than anyone else. His pipefitter experience tells him that sometimes what’s shown on a drawing doesn’t necessarily work on the job site. Having known Pat for 20 years, I have seen him grow and succeed in this industry, which makes me realize how fortunate we are to have him.”

Pat said, “I’m excited about working with Dennis and his team of people. He and I have known and respected each other for over 20 years.
