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.

The new name also embraces the global megatrend toward electrification, with Bosch announcing last month an investment of $737.6 million in electrification to further accelerate heat pump ramp-up, specifically as high demand for climate-friendly solutions continues globally. 

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.

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.

Johnson Controls-Hitachi’s new Yutaki M R32 monobloc air-to-water heat pump is an all-in-one solution, delivering heating, cooling and domestic water heater with an external tank.

Government planners, taking their queues from politicians and advocacy organizations, have steered the future of energy supply away from fossil fuels and toward renewably-sourced electricity. It’s happening on every level from the feds right down to local city councils.

A recent inquiry involved a heating system for a school in which two electric boilers were being added to supplement the output of a gas-fired cast-iron boiler, and take advantage of low “off-peak” electrical rates.

The MUZ-FS H2i plus heat pump from Mitsubishi Electric keeps homes warm and cozy in the winter and cool in the summer.

The System M consists of a sleek, quiet, inverter-driven outdoor heat pump that can be up to 4 times more efficient than a gas furnace, the company says.

Introducing the new Ascend Air-Water Heat Pump Model ACX from Trane (140-230 tons cooling, 1500-2500 MBh heating) – a perfect fit for meeting sustainability and efficiency targets for heating or cooling from one electric source, the company says.
