Ideal 175417 DHW Plate Heat Exchanger Kit

The Ideal 175417 is a plate heat exchanger kit rated at 24kW, supplied by Ideal for use in its domestic boiler range. The plate pack transfers heat from the primary circuit to the domestic hot water supply, so it sits at the centre of hot water production on a combi appliance. It is listed under the heat exchangers spare part category.

• Domestic hot water runs hot then cold, or the temperature swings while a tap is running
• Hot water flow rate drops noticeably compared with the cold supply
• Heating works normally but the hot water outlet stays lukewarm or cold
• Scale or debris blocking the plate channels, often after work on the primary circuit
• Water weeping from the plate stack or from the connections around the exchanger

• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
• Check the appliance model and GC number against the unit data badge before ordering.
• Confirm the part number 175417 matches the number on the existing component or the manufacturer's parts listing.
• Inspect the seals and gaskets on the exchanger connections and replace them if they are compressed or perished.
