Reheat Performance
The reheat times shown in the table are the time taken to raise the entire contents of the cylinder from 10 to 60oC using a single 3kW immersion heater. For faster reheat performance we can supply 6kW and 9kW immersion heaters to customer order.

Insulation
Direct has a single thickness of C.F.C free urethane foam lagging as standard, this adds approximately 50mm to the cylinder diameter.
Direct is available with a double thickness of C.F.C free urethane foam lagging on request, this gives lower heat loss and will add approximately 100mm to the cylinder diameter.
