Hajdu HGK-24 Smart combi condensing gas boilerHAJDU Hajdúsági Ipari Zrt. started manufacturing household appliances in 1957. At first, they only produced centrifuges and washing machines, and then gradually expanded their product range to include hot water tanks, indirect tanks, solar systems, boilers, buffer tanks and boilers. It is important for the company to satisfy consumer needs at the highest level possible, providing its customers with high-quality, environmentally friendly products, for which it guarantees a wide and reliable service and spare parts supply.The wall-mounted Hajdu HGK Smart condensing gas boilers, in addition to being used for heating and hot water production, are perfectly suitable for integration into a solar collector system. Not only is it an extremely environmentally friendly device, but you can also save 15-20% energy by using it. Since the device does not contain a changeover valve or plate heat exchanger, it requires minimal maintenance. It is basically a natural gas-powered device, but can be converted to LPG operation if required. Heating and hot water production can operate independently of each other thanks to the double water pipe solution. You can choose from three water heating functions during use. In the traditional function, the temperature of the heat exchanger is not kept constant, so hot water appears on the tap only after a short time, while in the comfort function, the boiler supplies hot water immediately. In the Eco function, i.e. the self-learning function, the device takes into account the timing of hot water withdrawal at the water withdrawal points. The long service life of the Hajdu HGK Smart gas boiler is ensured by the aluminum-copper heat exchanger. The boiler does not include a built-in closed expansion tank and safety valve, a mounting frame can be ordered as an option, which includes an 8-liter closed expansion tank. Any service information is displayed on the temperature display. The Hajdu HGK Smart boiler is an improved version of the HGK boilers. Its seasonal efficiency and heating performance have become even better, gas and electricity consumption have been reduced, domestic hot water comfort has been improved, and the boiler has also been equipped with a wireless thermostat receiver.Complies with ErP regulationsWall-mounted designExtremely environmentally friendly15-20% energy savingsEquipped with flow sensorCan also be operated in open heating systemsCompatible with Honeywell DTS92 and CMS927 wireless room thermostatsHeating and hot water production can operate independentlyA wireless thermostat receiver has been installedCan be converted to LPG operation on requestSimple and convenient to useRequires minimal maintenancePump with anti-sticking protectionThe device comes with a 60/100 mm starter connectorA mounting frame can be ordered as an optionExcellently suitable for integration into a solar collector systemIt has an aluminum-copper heat exchangerThree adjustable water heating functions: traditional, comfort and Eco functionPermitted flue gas systems: C13, C33, C43, C53, C63, C83With frost protectionQuiet operationModern appearanceHeating energy efficiency class: ADHW energy efficiency class: AWater intake profile size: L3-year full warranty and 6-year warranty on heat exchanger leaksThe image is for illustration purposes only!
