I always seek out the Bradford White booth to see what’s new and visit with friends both old and new. It was fun catching up with Carlos Morales because we had worked closely together several years ago in the development of the company’s gas-fired tankless water heater line. Lois and I had the opportunity to beta-test a number of tankless models and report back on their performance. Stability of delivery temperature; showering while other hot water usages ran simultaneously or intermittently; and, of course, attempting to max out the full-flow capacity.

Last month, we discussed the role of buffer tanks in combination with air-to-water and water-to-water heat pumps that operate as “on/off” devices. The key concept was to turn the heat pump on and off based on changes in the buffer tank temperatures and not based on thermostats calling for heat.

The very first installation of the Mikrofill 3 hydronic pressurization unit in North America took place recently in a mechanical room of an assisted- and independent-living community in Southwest-suburban Chicago. You might say the flower of this innovation grew from the soil of an old industry friendship.

More and more hydronic heating and cooling systems are being designed around air-to-water and water-to-water (geothermal) heat pumps. When the heating distribution system is extensively zoned, a buffer tank is typically installed between the heat pump and that distribution system.

Logic, technique and proven components are hydronic pro's hallmark

No conventional recipe for this hydronic pro.
March 15, 2023

Many hydronic installers look for ways to differentiate their work, to craft a specific look — maybe even a “brand” — that resonates with customers. For Fernando Lobo, owner of Fairfield, Connecticut-based 1 Call Services, that unique look begins with the raw material list he builds when sizing a boiler replacement, or new boiler install.
