Page 14: Boiler Room
[kW] tion from land Requirements for the boiler room ETA) Boiler rooms must be built with fire-resistant F90 (EI90) walls and ceilings; in Switzerland El30 up to 70 kW and EI60 over 70 kW. An escape door to a corridor or to the outside is required. - Page 15 Boiler room In Austria, no more than a week's supply of wood may be stored next to the boiler. For pellets, a separate storeroom EI90 (F90) with a EI30 (T30) door is required. As a result of amendments to building laws, up to 10 tonnes of pellets may be stored in the boiler room in some states.

This action prevents the boiler temperature from rising further and triggering further safety devices such as the safety temperature limiter. www.eta.co.at... - Page 17 Safety Safety devices Heat dissipation is limited by the selected maximum flow temperature in the heating circuits and the target hot water temperature. Safety shutdown by safety temperature limiter For additional safety against boiler overheating, a safety temperature limiter is built into the boiler. When a boiler temperature of 100 °C (tolerance +0°/-6 °C) is reached, the power supply to the draught fan and the fuel intake is interrupted.

The basic principle of the internal Tichelmann is diagonal flow; Two buffers are connected together at the top and bottom (= parallel connection). For output up to 90 kW, a connection with DN 32 (ETA buffer connection set) is sufficient, for 30 kW use at least R1" or 28 mm copper. On one tank, the boiler outlet is connected at the top; on the other the boiler return is connected at the bottom. - Page 35 Buffer storage tank Parallel buffer connection With fresh water module and stratified charging module Boiler, heating circuits, oil/gas boiler flow Oil/gas boiler return Boiler, high-temperature circuit return Low-temperature circuits return Fresh water module flow Temperature sensor [Sensor 1 (upper)] Temperature sensor [Sensor 2] Solar flow, top Temperature sensor [Sensor 3] 10 Solar flow, lower...
