What determines the high efficiency of the boilers? If it is properly planned and its sizing. In this post, all you will learn is about installing a condensing boiler. But before we proceed. We should also know about how it works.
How condensing boilers work?
When comparing a condensing boiler to a standard conventional boiler, the heat input is very much the same at the bottom. Roughly 250 to 350 degrees C. the burner inputs the heat at the start of the heating process. The burner is likely to be fitted with a small nozzle that atomizes the oil, much like putting your finger over the end of a hose. There’s 2 electrodes that light that oil and that’s what inputs the heat into the combustion chamber and the heat exchanger for transferring the heat into the water. If you have started to face any trouble with your boilers, you must contact with the boiler installation company in London.
The primary heat exchanger is set up in a group of baffles that all slide out when they need to be cleaned. There’s a burner fan down it so hot air, which is heated by the burner at the bottom, goes through the convector fins and tries to keep the heat in this area for as long as possible to allow the hot water to take heat away and off to the radiators.
Factors to be noted while installing condensing boilers
You have to look at several factors before installing condensing boiler. First of all you have to choose the features that you want to have control over. So ask these questions to yourself to have a better idea about which type of feature you want from the boilers.
- Do you want to use the system for both heat and hot water?
- Do you want to save energy when not in used?
- Do you want your boiler to perform in the most efficient way?
These questions will help you to locate your boiler and arrange for its installation.
Installation of the condensing boiler
Mark the 12 millimeter diameter holes to be drilled for the suspension brackets taking into account the minimum clearances. Insert the rural plugs and fit the suspension brackets using the screw supplied. Hook the boiler onto the suspension brackets using the mounting stay condensate drain connection. The trap must be fitted before installing the appliance. Before installing, apply silicone grease to the sealing corner. The trap included in the standard delivery must be fitted from underneath the appliance.
Removing the front casing, first undo the central screw at the bottom of the front casing. Push in the 2 locking hooks at the bottom left and right and pull the casing forward. Lift the front casing upward to release and remove it. Opening the control unit, push the retaining bracket on the casing upwards and pivot the control unit forwards opening the control unit back. Open the control unit cover using a screwdriver.
Inside the control unit
Let’s take you inside the control unit. You will see an outside temperature sensor, a cylinder temperature sensor, EBUS.
The heating socket, it is recommended to install a maintenance valve in both the heating flow and heating return. Note, you are recommended to use a sludge separator with integral magnetite separator in the boiler inlet to protect the high efficiency pump and the boiler. This is particularly relevant to old systems and the mixed installations.
Cold water and domestic hot water connection, it is recommended installing a maintenance valve into the cold water supply line. If the cold water supply pressure is above for the maximum permissible operating pressure of 10 bars, install a tested and certified pressure reducer.
Gas connection, connect the gas supply line at the gas connection or the expansion joint using a half inch gas connection and an approved sealant. Ensure the supply line is stress free. You must check the gas supply pressure. The gas boiler must be switched off when you fill the water in the flue pipe.
Open the gas ball valve. Switch the gas condensing boiler on by pressing button 5. After the boiler has started, read the supply pressure on the pressure gauge and enter it into the commissioning report. Turn off the boiler, close the gas ball valve, remove the pressure gauge and tighten the screw in the gas test connector. The further instructions must be read as provided by your manufacturers. You can get in touch with the boiler installation in London and get your boiler installed by a professional.
