We tackled issues at a 1953 apartment complex with a failing steam system, repairing pumps and leaks. This year, we discovered significant deterioration in the 6-inch steel steam main while preparing for its replacement, highlighting the poor condition of the aging infrastructure.

Air-to-water heat pumps, especially for larger systems, can be used in stages for efficient temperature control and flexibility, utilizing variable-speed compressors and specific piping setups to manage heating and cooling loads.

The first photo shows an oil-fired boiler and surrounding details. Take a close look, and make a list of what you would change in this portion of the system.

The 2024 Uniform Mechanical Code's Chapter 17 introduces Thermal Energy Networks (TEN), enabling buildings to independently manage heating and cooling sustainably, reducing environmental impact and enhancing energy efficiency across communities.

In Ottawa, a homeowner's dream of a luxury clubhouse with an outdoor pool comes to life with True North Mechanical's innovative heating system, ensuring a perfect New Year’s Eve party despite the freezing temperatures.

A review of a flawed hydronic heating system uncovers critical errors, such as improper circulator placement and restrictive mixing valves, leading to uneven warmth and corrosion issues. This underscores the need for proper design and installation in hydronic systems.

A hotel’s aging hot water system faces upgrades as leaking tanks are set to be replaced with smaller units. While a full redesign is desired for efficiency, budget constraints may limit the project scope, causing temporary hot water disruptions.

The photo in Figure 1 shows a non-pressurized outdoor wood-fired furnace connected to a floor heating subsystem via two PEX tubes. It includes a cast iron circulator, a thermostatic 3-way valve for mixing, a bypass linking supply and return tubes, and an "expansion zone" for another floor heating circuit. This setup is in a multi-million dollar home. Are there any potential issues with the installation?

The deadline to apply is Dec. 6.

The award is presented every two years to a nominee with attributes including technical mastery and a passion for hydronic technologies, demonstrated leadership as an educator and mentor, and an aptitude for cultivating fundraising opportunities for industry causes.
