A heating radiator is a heat regulator in which a hot liquid circulates and transfers the heat generated by radiation to the ambient air.Its often complex shape is designed to maximize warm space in contact with ambient air and heat dissipation.In this article, we want to discuss how to replace radiators:Turn off the water sourceYour first step is to turn off the central heating and allow the water in the system to cool down.If you have a thermostatic valve, make sure you turn it off and not just adjust the frost.At the opposite end of the radiator ( رادیاتورشوفاژ ) or towel rail is a valve that controls the flow through the system.This is a lockable valve.The main valves on the radiatorUse a protective cap.Screw the top piece of the square as far as possible with an adjustable wrench.Close the main control valveCount the number of turns required, because when replacing the radiator, the valve must open by the same amount.Drain the old radiatorPlace a bowl or bucket under the manual control valve.Grasp the valve body with an adjustable wrench.Hold it steady while using another wrench to loosen the nut, which is easily attached, to the adapter piece wrapped around the radiator.Drain the radiator by loosening the vent valveNow you have to empty the air radiator to break the vacuum inside and let the water come out of the control valve.

Gas heaters or heating devices are heating equipments that are produced in different types of radiation, fan and convection and are used for heating large industrial and domestic spaces.Gas heaters ( هیتر گازی ) consist of heat exchanger, atmospheric burner, intruder cap, limit control, control fan, oxypilot and fan.How the gas heater worksThe function of the heater and the hot air gas and diesel or dual-burner air furnaces is such that when the room thermostat operates.The burner of the device is switched on and the fan will not be allowed to operate until the oven temperature reaches a certain level.Similarly, when the room temperature exceeds the set limit, the thermostat issues the shutdown command and the heat source is turned off and until the temperature If the upper chamber of the furnace does not reach the specified level, the fan will not be allowed to turn off.The gas enters the atmospheric burner of the heater by controlling the gas valve, and when the burner is turned on, its heat moves in the heat exchanger and the burnt gases leave the chimney.When the heat exchanger (heater furnace) heats up, the axial fan passes through the plate.The cold air exchanger outlets heat the environment and throw the heater out and heat the desired environment.Types of gas heatersRadiant gas heater in all types of ceiling heaters, wall ceramic heaters and station heatersFan gas heater in various types of cabinet gas heaters and standing gas heaters - jet heatersGas heater without convection fan in all types of floor heatersSelect a gas heaterChoosing and buying different types of gas heaters requires information about the space used, such as the climate zone in which you live, the height of your ceiling, what rooms next to a room in which you are heating, what insulation work Be, does the room have direct sunlight, how big are the windows and do they have strong curtains or not, is the type of window double glazed or not?You can refer to Paya Dama website for detailed information on prices and technical specifications of gas heaters and get information from expert consultants.We will talk about the solutions for choosing the most suitable gas heater in future articles.

The unit heater or heating unit is an independent and single-season device that is able to work with different energies to heat a certain space.Potential energy sources are hot water, steam and natural gas.The components and equipment of the unit heater ( یونیت هیتر ) usually include a heat exchanger through which a fan heats the air from the room.It canBe with a butterfly or a squirrel cage fan.Airflow and blowing intervals are much greater with a squirrel cage fan.unit heater are strong enough to be used for primary heating and are versatile enough to integrate with existing ducts or in stand-alone settings.Types of Joint HeatersHeater units are divided according to the type of function.Gas unit heaterNatural gas heater units are equipped with a gas burner.Hot water heater unitSteam heater unitAdvantages• Decentralized and oriented heat.• Simple installation.• Wide power range of 25,000 Btu / hrUp to 400000 Btu / hr.• Quick solution for heating large spaces,Warehouses and garages• No need for a heat distribution network.• Simple to control with a tradeOr digital thermostat.• High efficiency achieved by condensing units.• Easy maintenance.Application of unit heaterHere are the most common uses for unit heater:• workshops;• Warehouses;• Garages;• factories;• Underground parking (multi-tenant building).Criteria for selecting a unit heaterHeating power:building typeHeating powerStore25-35 Btu / h per foot 2Mechanical store40-60 Btu / h per foot 2If the blowing distances of squirrel cage fans are preferredAnd the air flow that heats up is high or there is airPressure to deal with hot air outlet.They are hereCriteria to consider in selecting units:• Installation height;• Positioning;• Type of fan;• heating power;Combustion: Unsealed or dispersed combustion.Ventilation: Combustion products are usually ventilatedOutdoors by chimneys.Installation standards1.The minimum height to be respected,According to each manufacturer2.Installation somewhere is not recommendedChlorine products are solvents or explosives.3.

Concretely it has a heat generator , which can be a boiler for example, heating a coolant whose purpose is to convey the heat to radiators رادیاتور شوفاژ which will take care of distributing it in the various rooms of the house.Central heating radiators have the same type of operation as the towel radiators that are increasingly found in bathrooms in French homes and elsewhere.During your installation, it will therefore be necessary to have several radiators arranged throughout the home and which will guarantee your thermal comfort .Here is a quick point of the advantages and disadvantages of materials: Steel radiators : Generally they are quite designer and rise quickly in temperature which makes them more efficient more quickly.In addition, they are easy to install, fairly light compared to other models and present less risk of leaks .Its manufacturing cost is low, so it is very common for sale and distributed in mass.Cast iron radiators : Vintage and rustic in appearance, cast iron radiators are essential in the sector, they constantly restore heat and are recognized for their strength and quality .

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.
