Baxi Hydraulic Group 24kW 10 Litre 710064701

The hydraulic group is the manifold assembly that routes water through a Baxi combi boiler, carrying the diverter valve, pump connections and the associated waterways that switch the appliance between central heating and domestic hot water. This unit is rated at 24kW with a 10 litre capacity and is manufactured by Baxi for its 124 ErP and Neta-Tec combi families. It sits at the centre of the boiler's hydraulic circuit, so wear or scale here affects both heating and hot water performance.

• Domestic hot water runs cold or only warms intermittently while the heating circuit works normally
• Radiators heat up when a hot tap is opened, indicating the diverter is stuck in the heating position
• Hot water temperature swings sharply between draws, or the boiler cycles on and off during DHW demand
• Water weeping from the hydraulic block, manifold joints or the diverter housing
• Fault codes or lockouts linked to diverter position, flow or DHW sensing on the appliance display

• Check the appliance GC number and the serial number suffix against the compatibility list, as this hydraulic group is used across several 124 ErP and Neta-Tec variants
• Confirm the part number on the existing component matches 710064701 before ordering
• Note the alternative number 1119896 when cross-referencing older documentation or stock records
• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
