Honeywell exploits waste heat from telecomms stations
Heat from five cell-phone stations heat this unusual home, under the control of Honeywell heating controls.
Waste heat from telecommunications equipment supplies the total heating needs of a home in a 130-year-old water tower, thanks to the use of Honeywell heating controls. Owner Russell Harris converted Lymm Tower in Cheshire into a modern family home. Specially adapted Honeywell Excel controls were installed by Zalti Controls to provide individual control of 16 manifolds, each controlling an underfloor heating zone in the 510 m2 of living space. The accommodation comprises bedrooms and an office on four levels in the tower itself, plus a 2-storey ground-level extension providing more bedrooms and an open-plan living area. Five cell-phone networks use the tower as a base station. Each has a chilled-water cooling system for its electronics. Rejected heat is channelled through a heat exchanger to provide for the home’s heating needs. Robin Minton of Zalti Systems says, ‘The Excel control are very versatile and provide far better temperature control than would a conventional system. An Excel 50 controller communicated via a LonWorks module with LON distributed inputs/outputs. The controls are panel-mounted in the plant room, with an Excel 500 operator panel with digital readout in the living space.’ firstname.lastname@example.org
