Litres per hour per fixture calculated to 65°C. Demands based upon one hour recovery.
The data provided in this table should be used as a guide only. When calculating the required storage, consideration must be given to specific operational requirements.
The above demand rates are generally based on published sizing tables and include diversity factors. The data for hotels and fitness centres have been adjusted and represent demands based upon Ormandy’s experience. Please contact our engineering department if you require any additional information.
kW Rating Calculation
When the output has been finalised the following calculation determines what heat input (kW) is required.
