What are the key maintenance requirements for Worcester Bosch heat pumps?

Worcester Bosch heat pumps require annual servicing by a qualified engineer. During a professional service, the engineer will inspect the unit for damage or corrosion, verify panel fastenings and check for vibration, confirm water connection tightness and system pressure, ensure air pathways are clear, and check that the water drain tray and pipe are clear and clean. The engineer will also verify that controls, water pump, and fan are operating properly. Homeowners should not attempt these internal checks themselves.

Why is my Worcester Bosch combi boiler not producing hot water?

Common causes for a Worcester Bosch combi boiler not producing hot water include a faulty diverter valve (which directs hot water between taps and radiators), low water pressure, a frozen condensate pipe in cold weather, or a blocked plate heat exchanger. First check the pressure gauge reads between 1 and 1.5 bar. If you smell gas, do not operate any switches, leave the property and call the gas emergency line from outside. If the problem persists after checking pressure and thawing any frozen condensate pipe, contact a Gas Safe registered engineer.

Can I keep my existing radiators with a Worcester Bosch heat pump?

In most cases, existing radiators will need to be replaced with larger ones when installing a Worcester Bosch heat pump, unless they were already oversized. Larger radiators are necessary to ensure a higher Coefficient of Performance (CoP) from the heat pump, as heat pumps operate at lower flow temperatures than traditional boilers and require greater surface area to deliver the same amount of heat.
