What it is
The Ideal 176870 is a 40kW plate heat exchanger manufactured for Ideal domestic heating appliances. It is a brazed stainless steel plate pack that transfers heat between the primary circuit and the domestic hot water circuit, so the appliance can deliver hot water on demand without a stored cylinder. The unit sits within the hydraulic section of the boiler and is sized at 40kW to match the appliance's hot water output.
Signs this part needs replacing
- Domestic hot water runs hot then cools, or fluctuates between hot and cold during a draw-off
- Reduced hot water flow rate at the tap compared with the appliance's normal performance
- Scale or debris blocking the plate channels, common in hard water areas
- Water weeping from the plate pack or from the seals where the exchanger meets the manifold
- The appliance locks out or reports a hot water fault code during a demand for domestic hot water
