Design information (cont.) It may, for example, be installed in recreation rooms, in other living space, in ancillary rooms without ventilation, in cupboards (open at the top) and recesses without maintaining minimum clearances to combustible parts as well as in attic rooms (pitched attics and ancillary rooms) where the balanced flue pipe can be directly routed through the roof.
Design information (cont.) Thermally activated safety shut-off valve According to paragraph 4, sect. 5 of the FeuVo '96 [Germany], thermally activated shut-off equipment, that isolates the gas supply if external temperatures exceed 100 ºC, must be installed in gas combustion equipment or in gas supply lines. These valves must isolate the gas supply for at least 30 minutes up to a temperature of 650 ºC. This should prevent the formation of explosive gas mixtures in the event of a fire.

Design information (cont.) DHW circulation DHW circulation pipes increase DHW convenience and reduce water consumption. These advantages result from the immediate availability of hot water at the tap/draw-off point. However, poor insulation of the DHW circulation line can lead to substantial heat losses. From a line length of 7 m and longer, we recommend the installation of a DHW circulation line with appropriate thermal insulation in accordance with the Energy Savings Order [Germany].
Design information (cont.) Neutralising system C A B A Condensate drain B Neutralising system C Venting via the roof The Vitodens can (if required) be supplied with a separate neutralising system (accessories). Any condensate is piped to and treated in the neutralising system. The condensate drain to the sewer connection must be able to be inspected. It must be installed with a slope and stench trap on the sewer side, and must provide a suitable facility for extracting samples.
Design information (cont.) Heating circuits For heating systems with plastic pipes, we recommend the use of impermeable pipes to prevent the diffusion of oxygen through the pipe walls. Provide system separation in heating systems with plastic pipes to DIN 4726 that are permeable to oxygen. We supply a separate heat exchanger for this. Install a sludge separator in underfloor heating systems; see the Viessmann Vitoset pricelist.
Design information (cont.) Expansion vessel and heat sink for the solar circuit Stagnation in solar thermal systems All safety equipment in a solar thermal system must be designed for stagnation. If, in case of active insolation onto the collector array, the system draws no further heat, the solar circuit pump will stop and the solar thermal system enters a stagnation phase. Longer system idle times, e.g. through faults or incorrect operation, can never be completely ruled out.

Design information (cont.) Solar coverage The solar coverage indicates what percentage of the energy required annually for DHW or central heating can be covered by the solar thermal system. Designing a solar thermal system always entails finding a good compromise between yield and solar coverage. The higher the selected solar coverage, the more conventional energy is saved. However, this is linked to an excess of heat in summer.

Control units (cont.) The requirements of DIN EN 12831 for the heating load calculation are met. To reduce the heat-up load, the reduced room temperature will be raised in case of low outside temperatures. The flow temperature will be raised for a limited time to reduce the heat-up time after a setback period. According to the Energy Savings Order [Germany], the temperature in each room must be individually controlled, e.g. through thermostatic radiator valves.
