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.
