Generally, a central heating boiler is a replacement for a central boiler to simultaneously provide hot tap water and hot water for the heating system in apartments or villas.
It can be easily mounted on a wall or placed on the ground, offers higher energy efficiency and less fuel consumption versus a central boiler, eliminates the need for extensive piping in a building, and allows the independent supply of hot tap water and hot water for the heating system in each residential unit.Based on their installation, central heating boilers پکیج دیواری are categorized as wall-mounted and free-standing types.TYPES OF THE CENTRAL HEATING BOILERBased on their fuel, central heating boilers come in four categories:Gas-powered (silent wall-mounted or free-standing)Diesel-powered (free-standing, installed in the mechanical room or a storage room out of a residential unit)Bi-fuel (free-standing, installed in the mechanical room or storage room out of a residential unit)Electrical (silent wall-mounted or free-standing)Diesel-powered and bi-fuel heating boilers are of the free-standing type and mainly used in houses and residences with yards.Central Heating PackageBENEFITS OF A GAS-POWERED WALL-MOUNTED HEATING BOILERSilent operationSpace conservationAdjustable temperatureIndependence of residential unitsEase of installation, set up, and maintenanceAccessibility and adjustability from inside a residenceOptimal fuel consumption, high efficiency and heat exchange rate, and reduced fuel costsExcellent safety (featuring sensors for the hot tap water and heating water, as well as a smoke sensor)KEY PARAMETERS FOR SELECTING A GAS-POWERED WALL-MOUNTED HEATING BOILERAmount of hot water demandThe surface area of the residential unitChimney type (vertical up to the rooftop or horizontal)Providing the required oxygen for fuel combustion in the heating unitAccording to chapter 17 of the 2011 National Building Codes, the minimum surface area permissible for installing a heating boiler in a residential or business unit is 64 square meters; otherwise, an air intake is required for proper combustion.TECHNICAL TIP ON SELECTION AND PURCHASE OF THE CENTRAL HEATING BOILERSThe fanned boiler has an aeration fan in the exhaust part.
This kind of fan is used when the boiler is installed in open space (for example balcony and patio) or when some part of the chimney path is horizontal (more than 30 cm).
smoke discharges through this pipe.In double heat exchanger boilers, because of the existence of two heat exchangers (one for radiator heating system and one to supply warm water consumed), there is a constant flow of warm water.
Double heat exchangers boilers are used when the entering water is hard (high mineral content) or the building area is more than 120 m2.To approximately calculate the capacity of the boiler of the required heating boiler, the area of the residential unit is multiplied by 150 (Kcal), and the area of administrative units is multiplied by 100 (Kcal) (because administrative units do no consume a remarkable amount of water).
However, in residential units, due to the limited capacity of the units for the provision of hot water and the possibility of simultaneous hot water demand in both residences, a single heating boiler for two residences (even with small areas) is strictly not recommended.Some models of central heating boilers are equipped with an anti-frost system.
