The first and most popular method is for the occupants to monitor the temperature within the hot
water cylinder, using the controller, to ensure there is sufficient hot water for their requirements. The
temperature below which additional hot water is required will vary from household to household and
the occupants will determine this temperature over time. If additional hot water is required the
backup heating should be able to be turned on and once the water is up to temperature should be
automatically turned off. This manual control, providing the heating is automatically turned off,
should result in the backup heating being on the least amount of time and provide the greatest
savings.
Figure 26 “One Shot” Backup heating controller, allows manual control of the backup heating. The
heating is manually turned on and will be automatically turned off, maximising the savings from the
solar system
The EcoSolar UVR61-3 controller is able to automate the above process by determining if there is
sufficient hot water in the cylinder at the end of the day and automatically turning on and off the
heating as required. This allows the EcoSolar heating systems to be seamlessly integrated in to your
lifestyle.
Some systems rely upon a large cylinder with two or more immersion heaters, the ones at high level
being permanently switched on. Although this provides a continual supply of hot water, its operation
increases the amount of energy consumed and reduces the amount of energy savings the user is likely
