What it is
The Ideal 177667 is a hydroblock system assembly used on Logic System boilers. It carries the diverter valve and the associated hydraulic components that route heated water around the appliance, opening and closing to send water either to the radiators or to the domestic hot water outlets. The diverter gives priority to hot water, so when a hot tap is opened while the heating is running, the boiler serves the tap first.
Signs this part needs replacing
- Hot water runs cold or lukewarm while the heating is calling
- Radiators warm up when a hot tap is opened
- No hot water at the taps or shower even though the boiler fires
- Diverter sticking, giving intermittent heating or hot water
- Water weeping from the hydroblock area of the boiler
Before you order
- Check the serial prefix on the appliance: this assembly suits units from prefix ABU onwards but before prefix ACQ.
- Confirm the GC number on the boiler data badge against the compatibility list below.
- Cross-check the alternative part number 1783011 where the original number is not shown.
