Ideal 175419 Plate Heat Exchanger Kit

The Ideal 175419 is a plate heat exchanger kit rated at 35kW, produced by Ideal for use in its domestic heating appliances. The plate heat exchanger transfers heat from the primary circuit to the domestic hot water circuit, making it central to hot water production in a combi boiler. This is the 35kW variant of the kit.

• Domestic hot water runs hot then cold, or the temperature at the tap fluctuates
• Hot water flow is reduced or absent while the central heating continues to work
• Scale or debris has blocked the plate passages, which is common in hard water areas
• Water weeps from the plate stack or from the connections
• The appliance locks out or overheats when hot water is demanded

• 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 compatibility information for your boiler.
• Confirm that the number 175419 matches the item removed from the appliance.
• Inspect the seals and gaskets on the existing plate before fitting and replace them if they are compressed or damaged.
