The use of EC/DC motors in fan-coil units has introduced the opportunity to significantly reduce energy consumption.

There’s no stopping fan-coil units

The popularity of fan-coil units in air-conditioning systems has gone up and down over the years, but John Lightfoot argues that evolving technology makes them as valid an approach today as they have been in the past.

Commissioning as the key to energy efficiency

With energy costs continuing to rise, Albion Valves UK advises contractors and heating engineers that a well balanced commercial heating system can help address energy wastage. In a poorly balanced system, problems such as irregular temperature control and inconsistent water circulation can occur — driving up operating costs, creating maintenance issues and wasting energy.
