Harry Eklof & Associates has three locations, including a training facility located in Landover, Maryland. Distributors, contractors and engineers throughout the region can conveniently attend product demos, contractor certification classes and educational seminars. They also offer a full menu of virtual training opportunities.
The fourth edition of "Modern Hydronic Heating & Cooling, for Residential and Light Commercial Buildings" will be available through major booksellers on April 1.
With a considerable volume of contradictory information in circulation regarding the application of different technologies for HVAC systems, this article seeks to explain some of the technical aspects of variable refrigerant flow (VRF) systems, and offer comparisons on the basis of cost and performance to more standard hydronic systems.
Last month, we discussed using a non-pressurized thermal storage tank, in combination with brazed plate heat exchangers in a system supplied by a cordwood gasification boiler.
The Hercules Cryo-Tek original antifreeze is designed for use in hydronic heating and cooling closed-loop systems, most solar heating systems, snow melts, radiant heating, and general plumbing systems.
The classic way of estimating heating load in smaller, envelope-dominated buildings is to assume the rate of heat loss is proportional to the difference between the inside and outside temperature.
In last month’s column, I presented a “template” for a system that provides space heating, cooling and domestic water heating using a cold climate air-to-water heat pump as the primary heat source, and the sole source of chilled water for cooling.
