The seven-year contract for Midea calls for the development and delivery of 20,000 cold climate packaged window heat pump units – devices that support the city’s move away from natural gas and towards more efficient energy sources.
The new Midea EVOX central inverter heat pump system is one of the most compatible inverter products available and is competitively priced despite some of the highest energy ratings, the company states.
As global energy planning moves away from fossil fuels and toward electricity, an increasing number of hydronic heating systems are being supplied by heat pumps. Some use water-to-water heat pumps supplied by geothermal earth loops. Others use air-to-water heat pumps.
Over the last few years, I’ve written several columns describing how air-to-water heat pumps can provide heating, cooling and domestic hot water for homes. Many of the systems involve buffer tanks to help stabilize heat transfer from the heat pump to a zoned distribution system.
Heat pumps offer attractive solutions to energy-efficient heating and cooling, and the market is growing. According to a November 2021 report from the International Energy Agency (IEA), nearly 180 million heat pumps were used for heating in 2020, as the global stock increased nearly 10% per year over the past five years.
The fourth edition of "Modern Hydronic Heating & Cooling, for Residential and Light Commercial Buildings" will be available through major booksellers on April 1.
As interest and incentives build to transition space heating and domestic water heating systems away from fossil fuels and toward electricity, a somewhat predictable but only marginally quantified problem is developing. Two words describe it: Peak demand.
