boiler+pipe Saunier Duval THEMA CLASSIC F 25 UN UA

Saunier Duval ThemaClassic F 25 UN UA 0010006166 One of the most popular in Europe, Combi boiler Saunier Duval ThemaClassic F 25 with closed combustion chamber, with a capacity of 24 kW, electric ignition. Designed for heating, namely to ensure the needs for hot water and space heating, equipped with water heating systems and water supply. Saunier Duval boiler ThemaClassic F 25 can provide hot water to 11.3 liters per minute at DT=30 °C, and heat conditional area of about 230 m2. Gas boiler automatics has high sensitivity and enables to operate at low gas pressure. The boiler has the opportunity to work on natural and liquefied gas. To convert the boiler to work on liquefied gas, it is necessary to replace the nozzle and the gas valve. Equipment boiler Themaclassic F 25: gas atmospheric burner block ignition and flame control, gas valve with modulating stepper drive, providing precise control and small dimensions, with the safety valve of the gas block (EVS), which cuts off the gas supply in emergency situations, primary copper heat exchanger, steel DHW plate heat exchanger, mechanical filters built into hydrograph, single-speed pump, expansion tank, the pressure sensor, the three-way valve with actuator, relief valve, automatic air bleeder, built-in adjustable bypass, built-in manual valve for feeding the heating system with a check valve, fan (boilers sealed combustion chamber), control panel with LEDs and LCD display control Board with built-in microprocessor. Safety devices and protective functions of the boiler: relief valve, the pressure sensor coolant emergency temperature sensor, the sensor DHW flow with an improved protection system from clogging and fouling, thermostat thrust (in boilers with an open combustion chamber), manostat thrust (in boilers sealed combustion chamber), function heat antinelli (run-on pump), function antitelephone pump, the antifreeze function of the boiler, function anticyclical boiler, the start-up delay mode DHW, the function of maintaining a predetermined temperature DHW, the function of cutting off the gas supply, the safety valve of the gas block. In case of a power outage boiler turns off and when the utility power will be incorporated in the work, keeping all presets. The boiler has the ability to adjust the power of the heating system, depending on needs without changing the maximum power for hot water systems. The boiler can be connected: room thermostat (simple or programmable); the chimney damper with actuator; the ambient temperature sensor; both sensors simultaneously. Thus, the operation of the boiler is carried out with equivalent thermal regulation and adjustment room thermostat; clock; device "DIACOM" deep diagnostics of boiler services.
