Abstract
The authors report the first results obtained with Gerbera crop (Gerbera jamesonii H. Bolus) in glasshouse heated by waste heat (22°-25°C) available from a wet tower cooling system.
The waste heat was distributed in the air by an air-forced exchanger and in the substrate by polyetylene pipes.
A similar glasshouse, as control, was heated in the air at 15°C minimum temperature, by a conventional electric system (aerotherm). Gold Fire, Boston and Charleston were the cultivars tested.
The production of cut flowers in both glasshouses was satisfactory as quantity and quality; no difference was noticed between the two glasshouses.
The annual economic saving attainable by using waste heat was evaluated to be 18,000 1L/m2.
