What it is
The Ideal ErP complete hydroblock kit is the hydraulic assembly that manages water flow between the domestic hot water and heating circuits on Logic System IE appliances. It carries the diverter and hydraulic components that switch the boiler between hot water production and central heating. This kit is supplied as a complete unit for the System IE range.
Signs this part needs replacing
- Domestic hot water runs cold or only warms intermittently while the heating is on
- The boiler fails to switch between heating and hot water demand
- Water weeping or staining around the hydroblock body or its connections
- Diverter operation feels stiff, noisy or sticks during a demand change
- Heating output continues when only hot water is called for, or the reverse
Before you order
- Confirm the GC number on the appliance data badge against the compatibility list, as the same model name can cover more than one build
- Check the existing part number on the unit before ordering, and note the alternative number 1783013
- Inspect the seals and connections on the existing hydroblock, as these are disturbed during replacement
- Work on the hydraulic circuit should follow the manufacturer's instructions for draining and refilling the appliance
