What it is
The hot outlet pipe is a water-carrying component used in Alpha 25C, 28C and 35C appliances. It forms part of the domestic hot water circuit, taking heated water away from the heat exchanger assembly and directing it towards the outlet side of the boiler.
This is a direct replacement pipe supplied under Alpha part number 1023570, also listed under the alternative number 023570. It is a metal pipe section rather than a gas-carrying component.
Signs this part needs replacing
- Water weeping or dripping from the pipe or its connection points during hot water draw-off
- Visible corrosion, pitting or green/white scale deposits on the pipe surface
- Reduced hot water flow or temperature at the tap that traces back to a restricted or scaled outlet pipe
- Staining or damp patches inside the casing beneath the pipe run
- A joint that will not seal after the pipe has been disturbed during other repair work
Before you order
- Confirm the appliance model and GC number from the data badge, as the 25C, 28C and 35C variants use different assemblies in places
- Check the existing pipe against part number 1023570 and the alternative number 023570 before fitting
- Inspect the seals and washers at each connection and renew them if they are disturbed during removal
- This item is not a gas-carrying component, but any work inside the appliance casing should be carried out by a competent person
