Offering huge savings on the cost of providing hot water, Itho Daalderop drainback pre heat systems consist of a 90 litre or 150 litre solar cylinder, a drainback unit and one or more solar collectors. The systems can be used with either landscape or portrait collectors, and can be installed in homes with pitched or flat roofs.
What makes the drainback 90 & 150 systems unique is that they are coupled with a condensing combination boiler rather than a conventional boiler and twin coil cylinder. The result is considerable energy savings without the need for complicated controls or programmers. The end user always has hot water, on demand, at the turn of a tap.
Combined with an Itho Aqua-Max condensing combination boiler, this system can provide generous amounts of hot water at 60°C per minute all year round. Itho drain back technology also ensures that the system requires minimal ongoing maintenance without the need for chemical treatment to protect against frost in the winter months.
