• Manufactured: 2007 - Current
• Power Consumption: 21.00 - 21.00KWhThe output power of the boiler (to water) in kW (kilowatts - 1000 watts). For boilers with SEDBUK efficiency figures this is the rated output which is needed for the purpose of the Boiler Efficiency Directive (Council of the European Communities Directive 92/42/EEC). If the power is only declared in BTU/hr then it will have been converted using the following formula - 1 watt of electricity equals 3.41 BTU/h (British Thermal Unit per hour). If the boiler is range rated then both the lower and higher limits of the range are given. If it is a modulating boiler then the modulating range is given.
• Energy Efficiency Band: AThe rating scheme has been created with SEDBUK efficiency bands assigned to boilers from A to G (A being the the most energy efficient rating). The energy efficiency band ranges and is based on the SEDBUK rating scale, with an A rating having an efficiency level of 90% and above. For more information see our SEDBUK rating definition page.
• Seasonal Efficiency: 90.30%The average efficiency when the boiler is at part and full power, rounded to the nearest 0.1%.
• Fuel: GasNatural gas is the gas fuel that you get from the gas mains and is the most common form of boiler fuel. Natural gas is often informally referred to simply as gas.The type of fuel that the boiler uses, which will be 'gas', 'LPG' or 'oil'. If the same boiler may use more than one type of fuel then separate entries for each will be listed.
• Mounting: WallThe boiler can only be mounted on the wall.The boiler mounting position, which will be either 'unknown', 'floor', 'wall', 'either floor or wall', or 'back boiler'.
• Condensing: Non-condensing
• Flue One: Room SealedThe room is sealed and has no contact with the gases that exit via the flue.Describes the boilers flue system which will be one of 'unknown', 'open' or 'room-sealed'.
• Flue Two Fan: Fan
• Ignition: Permanent Pilot Light
• Burner Control: Variable
• Elec Power Firing: 120 Watts
• Insulation Thickness: -
• Store Volume: -
• Main Type: CombiA combi boiler provides hot water directly, and no cold water tank or pipes are needed in the loft space. They are usually best suited to smaller homes (where there will not be demands for water from more than one tap at the same time).Describes the boilers type which is defined as either 'regular', 'combi' or 'CPSU'.
