What it is
The Ideal 170995 is a plate heat exchanger kit manufactured for Ideal Isar appliances. The plate heat exchanger transfers heat between the primary circuit and the domestic hot water circuit, so it sits at the centre of the appliance's hot water performance. This kit is supplied with the screws and washers needed to mount the exchanger during the repair.
Signs this part needs replacing
- Domestic hot water runs hot and cold, or the temperature fluctuates at the tap
- Reduced hot water flow rate compared with the cold supply
- Scale or debris blocking the plate passages, common in hard water areas
- Water weeping from the plate pack or from the seals around the exchanger
- Poor heat transfer between the primary and secondary circuits, with the boiler firing but the tap water staying lukewarm
Before you order
- Confirm the appliance model and, where available, the GC number against the compatibility list before ordering.
- Check the existing plate heat exchanger and its mounting hardware to confirm the kit matches what is fitted.
- Have new seals or gaskets to hand if the existing ones are disturbed during removal.
- This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
