INTEGRA 500/120 heater
INTEGRA 500/120 heater
Tank in tank combination storage INTEGRA 500/120 is designed for heating domestic hot water and solar support of central heating. It also integrates multiple heating sources in one system.
Information about the product
INTEGRA 500/120 is a tank inside a tank solution. The inner tank is used for heating domestic hot water by taking the heat from surrounding hot water. Hot water may be heated by mutliple sources at the same time: boiler, heat pump, fireplace with water jacket or an electric heater as well as indirectly - through solar thermal system using a coil heat exchanger. Therefore a solar thermal system not only heats the domestic hot water, but also supports central heating in the building. Due to its higher capacity, INTEGRA is also a heat buffer and a hydraulic coupling. It is usefull in heating systems with multiple heat sources and heating circuits. It eliminates negative interference of heating circuits and heating sources (hydraulic separation, ensurance of required water flow).
The internal domestic hot water tank is powered from the bottom with tap water, which lets the lower part of the heater cool down (solar thermal system can give away more heat). It also guarantees easy maintenance (the tank may be easily emptied in order to, for example, rinse it). The outer coat, which collects heating water, has more pipe stubs and allows connection of multiple heating sources. In a solar thermal system, heating water is warmed by a coil heat exchanger, therefore the water is separated from glycol.
INTEGRA`s special feature is its clear division into temperature zones through built in barriers in buffer part (on the side of heating water), as well as inserts which diffuse the water streams incoming from heat sources or the heating system of the building. The bottom zone has the lowest temperature and allows higher heat accumulation from solar thermal system, as well as the boiler or fireplace with water jacket. The upper zone is one with the highest temperature and works as a heat reserve for heating domestic hot water. The middle zone is connected to building`s heating system. A large number of pipe stubs allows connection of heat sources to various zones, depending on work parameters and regulation capacity.
Solar thermal system works in a standard mode, which is based on temperature difference of 1-2. Sensor no 2 is in the bottom zone of the heater in the heating water. Gas boiler gives power to middle zone of the heater, which is connected to building`s heating system. Solid fuel boiler is connected to the bottom zone of buffer tank. Operation of heating circuit pump is controlled through senson number 3. Domestic hot water is heated in built in storage and gains heat from heating water. If the domestic hot water is heated by a boiler using G422 controler, then sensor number 4 is connected to that controller (otherwise the domestic hot water sensor is put in place of sensor number 4).
INTEGRA heater is equipped with 100mm thick polyurethane foam insulation, which limits heat loss. Energy effeciency class „C” proves high standard as well as optimum relation of energy efficiency to purchase and operation costs. The case is made of hard plastic, resistant to dirt and damage.
