The cylinder is made from stainless steel and is insulated with EPS with heat radiation absorbers. The unvented domestic hot water cylinder works with the pressure of the water supply line and does not need a cold water tank for its supply.
Operation 4 4 Operation a Danger! Risk of scalding and bursts due to inappropriate alterations! There is a risk of escaping steam, bursting, and damage to the system if you make any changes to the cylinder, control system, supply lines for water and power (if present), relief valve termination, or expansion relief valve for the cylinder water. > Do not make any improper changes.
4 Operation i If the uniSTOR has been installed in a cupboard used for airing clothes, make sure that clothing and other objects are not placed on the cylinder, control devices, pipes or other system components. i Always make sure that there is clear access to the cylinder to enable the use of the hot water thermostat controller and the thermostat mixer. 4.2 4.
Operation 4 4.7 Energy-saving tips Appropriate hot water temperature The warm water should only be heated up to the extent that is necessary for use. Any further heating results in unnecessary power consumption and hot water temperatures of more than 60 ºC also lead to increased lime scale production. Run circulation pumps only if needed Circulation pumps do indeed increase convenience when it comes to hot water production. But they also need power.
5 Inspection and maintenance 6 Recycling and disposal 5 Inspection and maintenance An annual inspection/maintenance carried out by a competent person is a prerequisite for ensuring that the cylinder is permanently ready for operation, reliable, and has a long working life. It is important that your hot water cylinder is serviced annually. We recommend entering into a maintenance agreement.
