Heating Radiators with Fire Log burners are commonly available with a wetback system that heats • Heat more of your home with a hot water cylinder. It’s possible to extend the functionality of the your fire wetback by using radiators to spread the heat to other parts of the house. • Radiators available in a This means you can get the pleasure of watching a fire burn in your living variety of styles and endless room while the rest of the home is brought to a comfortable temperature colour options by the radiators. • Using a cheap and reliable People often try to move the hot air from a fire into other parts of the source of firewood means no house with duct work. Moving heat with water is so much more effective additional fuel costs as water transports energy four times better than air. The number of radiators you can heat depends on the heat output of the wetback and the rating of the radiators. A typical wetback only provides 2 to 4kW of heat as this is all that is needed to heat a hot water cylinder if the fire is on for five to ten hours per day. In order to heat a central heating system, a wetback with a higher output is often required. There are fires that have larger wetbacks (up to 15kW) and put out more heat to the wetback, enabling more radiators to be connected. How It Works While the fire is burning, the heat from the combustion process heats water jackets installed within the firebox.

  • Consumer Guide: Balancing the Central Heating System
    Consumer Guide: Balancing the central heating system System Balancing Keep your home heating system in good working order. Balancing the heating system Balancing of a heating system is a simple process which can improve operating efficiency, comfort and reduce energy usage in wet central heating systems. Many homeowners are unaware of the merits of system balancing -an intuitive, common sense principle that heating engineers use to make new and existing systems operate more efficiently. Why balance? Balancing of the heating system is the process of optimising the distribution of water through the radiators by adjusting the lockshield valve which equalizes the system pressure so it provides the intended indoor climate at optimum energy efficiency and minimal operating cost. To provide the correct heat output each radiator requires a certain flow known as the design flow. If the flow of water through the radiators is not balanced, the result can be that some radiators can take the bulk of the hot water flow from the boiler, leaving other radiators with little flow. This can affect the boiler efficiency and home comfort conditions as some rooms may be too hot or remain cold. There are also other potential problems. Thermostatic radiator valves with too much flow may not operate properly and can be noisy with water “streaming” noises through the valves, particularly as they start to close when the room temperature increases. What causes an unbalanced system? One cause is radiators removed for decorating and then refitted. This can affect the balance of the whole system. Consequently, to overcome poor circulation and cure “cold radiators” the system pump may be put onto a higher speed or the boiler thermostat put onto a higher temperature setting.

  • Radiator Antifreeze Plugging Problem in Gasoline Engines
    Radiator/Antifreeze Plugging Problem in Gasoline Engines April 2006 We were recently asked to investigate the problem of a radiator plugged with a white substance that was solid, semi-solid, or gelatinous in consistency depending on where it was removed from in the radiator. <circumstances:< b="">The vehicle that this radiator came from had recently been serviced using a radiator flush product, followed by the addition of new coolant and a cooling system supplement.</circumstances:<> At some point after this service the vehicle was returned to the service location with an overheating problem. It was determined that the radiator was plugged with a white foreign substance requiring the replacement of the radiator and antifreeze. Our investigation centers on the source of the substance that restricted coolant flow in the radiator. We proceeded with laboratory testing of the samples removed from the radiator. What we have found is consistent with what is known as "Silicate Drop Out". Most antifreeze used in North America is Ethylene Glycol based. Corrosion inhibition for aluminum engine and cooling system components that are in contact with coolant (heads, intakes, radiator, e.g.) is generally provided by adding alkali metal silicates and silicone to the coolant. These silicates under certain circumstances (coolant with a depleted additive package (worn out coolant), hard water (water mixed with coolant), high coolant temperature, over concentration of coolant (not enough water)) have a tendency towards "polymerization", which can cause silicate "dropout" or "precipitation" which can lead to gelation of the silicates in the coolant. When this happens, the interior of the cooling system and engine are coated with a white gelatinous material that significantly reduces heat transfer and slows or even stops the circulation of coolant within the system.

  • Stelrad.Com Bleeding a Radiator the Process of Bleeding a Stelrad
    Stelrad Limited Telephone: +44 (0) 1709 578950 Stelrad House, Marriott Road Facsimile: +44 (0) 1709 572200 Mexborough, South Yorkshire S64 8BN Stelrad.com Bleeding a Radiator The process of bleeding a Stelrad Radiator is to let out any trapped air that is inside the radiator. Bleeding your Stelrad Radiator will improve the efficiency of your heating system. This guide has been designed to guide you through the process of bleeding your Stelrad Radiator safely, should you have any concerns, please seek professional advice. To bleed your Stelrad Radiator you will need the following tools: • A radiator bleed key/Flat headed screwdriver • A cloth/Small hand towel Step 1 Ensure your central heating and hot water are switched off at the boiler, and that the radiator you are planning to bleed is completely cooled. Step 2 To locate the valve to bleed the Stelrad Radiator, check along the top edge of the radiator - the release valve is a square shape inside of a round hole. Place your radiator key and twist anticlockwise slowly, just a quarter to a half turn (never fully open the valve). You will hear a hissing sound as the air escapes. Step 3 When you hear the hissing sound of the air escaping, hold your cloth beneath the valve to catch any water. As soon as water is escaping, close the valve back up on the Stelrad radiator by turning the radiator key clockwise. Step 4 Repeat the bleeding process on any other Stelrad Radiator that requires it – starting on the Stelrad radiators downstairs and then moving upstairs if required.

  • Transient Radiator Room Heating—Mathematical Model and Solution Algorithm
    Article Transient Radiator Room Heating—Mathematical Model and Solution Algorithm Armin Teskeredzic * and Rejhana Blazevic Faculty of Mechanical Engineering, University of Sarajevo, Sarajevo 71000, Bosnia and Herzegovina; [email protected] * Correspondence: [email protected] or [email protected]; Tel.: +387‐62‐991‐918 Received: 2 October 2018; Accepted: 12 November 2018; Published: 18 November 2018 Abstract: A mathematical model and robust numerical solution algorithm for radiator heating of an arbitrary room is presented in this paper. Three separate and coupled transient thermal energy equations are solved. A modified transient heat conduction equation is used for solving the heat transfer at multi‐layer outer walls and room assembly. Heat exchange between the inner walls and the observed room are represented with their own transport equation and the transient thermal energy equation is solved for radiators as well. Explicit coupling of equations and linearization of source terms result in a simple, accurate, and stabile solution algorithm. Verification of the developed methodology is demonstrated on three carefully selected test cases for which an analytical solution can be found. The obtained results show that even for the small temperature differences between inner walls and room air, the corresponding heat flux can be larger than the transmission heat flux through outer walls or windows. The benefits of the current approach are stressed, while the plans for the further development and application of the methodology are highlighted at the end. Keywords: radiator heating; mathematical model; numerical solution algorithm 1. Introduction The current energy policy of the EU member states is promoting energy efficiency in buildings as one of the key pillars in the strategic energy documents.
