What it is
The Ideal 178110 is a complete hydroblock kit for the ErP generation of 35kW combi boilers. The hydroblock is the hydraulic assembly that controls water movement through the appliance, carrying the diverter valve, flow sensing and the associated pipework connections in a single unit. This kit is the base variant supplied for the 35kW ErP platform.
Signs this part needs replacing
- Domestic hot water runs cold or fluctuates while the central heating is running
- Radiators heat up when only hot water is drawn, pointing to a stuck diverter
- No hot water demand registered, or the boiler fails to switch to DHW mode
- Water weeping from the hydroblock body, joints or connections
- Fault codes relating to flow, diverter position or water pressure
Before you order
- Confirm the model and GC number from the appliance data badge, as the kit is specific to the 35kW ErP platform.
- Cross-reference the alternative part number 1783015 against older listings and documentation.
- Inspect the existing seals, O-rings and washers when the old hydroblock is removed and replace any that are damaged.
- Work on the hydraulic circuit should follow the manufacturer's service instructions for the appliance.
