Low Ambient Air-to-Water Heat Pumps: An emerging renewable heat source for North American hydronic systems.
Electrically powered heat pumps, in many varieties, are destined to play an increasingly important role in heating and cooling buildings around the world.
Heat pumps capture low grade heat from solar-resupplied sources such as outside air and soil several feet below the earth’s […]
Sizing a Pellet-Fueled Boiler
Bigger is NOT better
There are several types of boilers that can burn wood-based fuels. They include 2- stage wood-gasification boilers, wood chip boilers, and pellet-fueled boilers. Of these, pellet-fuel boilers come closest to mimicking the fully automatic operation of oil and gas- fired boilers. Modern pellet boilers can automatically load their fuel, […]
Hydronic Heating with Renewable Energy Heat Sources
Designing for low water temperatures is critical to good performance
This article focuses on using water-based hydronic distribution systems to distribute heat produced by renewable energy heat sources. It’s based on the premise that good hydronic design is the “glue” that holds together nearly all thermally based renewable energy systems […]
We created the Hydronics Design Studio (HDS) to assist heating professionals in designing high performance hydronic heating systems. It represents the state-of-the-art in computer-assisted design for modern hydronic heating systems. Thousands of professionals use the HDS, but if you’re not yet familiar with it, I’d like to offer you a free demo version to get acquainted with the […]
