Ideal Heat Exchanger Assembly Super VH Series 4 100805

The Ideal 100805 is a heat exchanger assembly supplied for the Ideal Commercial Concord Super Series 4 range. It sits at the core of the appliance, where heat from the burner is passed into the circulating water before that water is distributed around the heating system. As a primary component, it is replaced when the existing exchanger has been damaged by scale, corrosion or overheating.

• Heating output drops noticeably, with radiators failing to reach temperature even when the burner is running
• Kettling, banging or rumbling noises from the appliance as the water boils locally on a scaled or restricted exchanger surface
• Water weeping from the exchanger body, its joints or the surrounding casing
• Repeated high-limit trips or lockouts caused by poor heat transfer and rising flow temperatures
• Visible corrosion, pitting or soot deposits on the exchanger surfaces during a service inspection

• Confirm the appliance model and serial number against the compatibility list, as the Concord Super Series 4 range uses more than one exchanger variant
• Check the existing part number and cross-reference it with 1175340 before ordering
• Inspect the seals, gaskets and connections around the exchanger, as these are commonly renewed at the same time
• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
