The 2019 AHR Expo was as successful as ever for Patterson-Kelley. The P-K team was able to make new connections, unveil new technology and reconnect with representatives, contractors and consulting engineers. The event welcomed over 65,000 HVAC/R professionals to the World Congress Center in Atlanta, GA, between January 14th and January 16th. Patterson-Kelley presented its commercial boilers and water heaters, as well as its fresh look; the P-K logo signaling over a city skyline, asking for on-lookers to “Answer the Call.”

Commercial Boiler Efficiency
Placing system efficiency at the forefront of commercial boiler acquisition continues to be a trend in the heating and water heating industry. Manufacturers are racing ahead to push the limits of technology by offering aggressive turndown capabilities approaching, and even exceeding 20:1, at the detriment of system efficiency.

Examining Direct Fired Water Heaters
It comes as no surprise that technological advances in the water heating industry have allowed manufacturers to develop highly efficient commercial boilers that provide well rounded heating comfort. Utilizing commercial boiler platforms to produce both building heat and domestic hot water has become a trend in the industry, but what does this mean for the commercial units?
Direct Fired Water Heating Solutions

Hot Water in an Instant
Whether you take long, hot showers in the morning or use large amounts of hot water at your workplace, the need for a water heating system that is consistent and reliable is crucial. Water heating technology has made amazing breakthroughs, and today manufacturers can offer water heating solutions for a variety of needs.
Best Boiler Maintenance Practices

Why Annual Maintenance?
Like changing the oil of your Ferrari F60 every 3,000 miles, all heating equipment, both boilers and water heaters, require annual maintenance. No matter the life expectancy of a heating system, ‘WEAR & TEAR’ will interfere with the performance of your heating equipment.

Boiler Control Innovation

The technological innovation of boiler systems has drastically enhanced how users interact with their boilers. The industry continues to improve safety and efficiency standards to fit the game changing environment. Today, users seek features that influence the return on their investment. These notable features include increased energy efficiency, great zone controls and low operational costs; all of which can be achieved by selecting the right boiler control technology.

Operate at Peak Efficiency
Boilers are Rated on Thermal Efficiency
Thermal efficiency is simply the chemical energy added to the boiler divided by the energy added to the boiler water. As more energy is transferred from the hot gas into the boiler water, the thermal efficiency increases and the temperature of the hot gas decreases.
Water Quality - Essential for Optimal Performance
[fa icon="calendar'] Apr 18, 2018 12:03:21 PM / by Patterson-Kelley posted in Condensing Boilers, Water Quality, Hydronic Boilers, Non-Condensing Boilers
Why is Water Quality Important?

Importance of Water Treatment
Water treatment is essential to ensure peak boiler performance and operational efficiency. Up to 15% of thermal loss occurring within the first two years of boiler operation can be attributed to poor water quality. Untreated water inside a boiler can cause the following: overheating, failure to produce hot water, and shortened life expectancy of the system.
