Last month's column discussed piping for air-to-water heat pumps. A 2-pipe system allows staging but not simultaneous heating and cooling, while a 4-pipe system with motorized valves enables both modes of operation.

An emergency call led a team to a school with a leaking boiler, which was shut down due to safety concerns. After clarifying the need for urgent repairs, the executive director approved the work. Complications arose from snow and transport challenges, but a friend connected them with a group of young workers willing to help, easing manpower concerns.

Occupants of a building using a hydro-split air-to-water heat pump are facing slow recovery after night setbacks and inadequate hot water during peak demand. The system, composed of an outdoor and indoor unit, struggles with heating efficiency. What improvements could enhance its performance?

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.
