Ask a Plumbing Engineering Pro: When Should Heating Systems be Converted from Steam to Hot Water Distribution?

Steam heating is popular in many buildings for a very simple reason: Steam rises by itself, which made it a practical medium to deliver heat before electric water pumps became a widely available plumbing engineering choice. In new constructions, hot water systems with hydronic piping are by far the best choice, both in terms of efficiency and environmental impact. The main reasons why many steam-based systems are not replaced are the upgrade cost and the [...]

A Plumbing Engineering Expert’s Guide to Variable Refrigerant Flow (VRF) Systems

A Comprehensive Guide to Variable Refrigerant Flow (VRF) Systems Functions: Heating and Cooling VRF systems use refrigerant as the heat-carrying medium instead of water, as implied by their name. A pump is controlled by a variable-speed drive to adjust the flow of refrigerant, depending on current load. These plumbing engineering systems are easy to install once contractors get familiarized with them, while also providing flexible operation and a remarkable energy efficiency. Another advantage of [...]

A Plumbing Engineering Expert Explains Storage and Demand-Type Water Heaters

Water heaters are household appliances that normally use natural gas or electricity to produce heat, and often include a tank to store hot water. These plumbing engineering systems provide a very important service for modern society, especially in locations with cold winters. Water heaters represent a significant portion of building energy expenses, so an optimal design is very important to achieve low-cost operation. The following summarizes the main types of water heaters: Traditional tank-type [...]
