Based on our experience repairing Vaillant appliances in St Thomas, these are the most frequent error codes and faults.
What does the F.022 error mean on a Vaillant heat pump?
The F.022 error on a Vaillant heat pump means water pressure in the heating system is too low. Top up using the filling loop if pressure is below 1.0 bar. If pressure drops repeatedly, contact a qualified heating engineer.
What does the F.29 error mean on a Vaillant boiler?
The F.29 error indicates flame loss during operation with unsuccessful re-ignition. Check gas supply and inspect for frozen condensate pipe in cold weather. If gas supply is confirmed and the pipe is not frozen, contact a Gas Safe registered engineer.

Frequently Asked Questions - Vaillant Appliance Repair St Thomas
What is checked during a Vaillant heat pump service?
A Vaillant heat pump service includes a rigorous 28-point check covering visual inspection of the system, temperature and performance testing, pipework and pressure checks, leak detection, and electrical circuit testing. The engineer also provides professional advice on system setup and use.
How often should I service my Vaillant heat pump?
Vaillant heat pumps should be serviced once a year to maintain optimal efficiency, identify potential issues early, and keep the manufacturer warranty valid. Annual servicing is a requirement of the heat pump guarantee terms.
Why do I have no hot water but the heating works?
On a combi boiler, this often indicates a problem with the diverter valve, which directs hot water either to radiators or to taps. It may also be a settings issue where the boiler is set to heating only. Check your boiler display to verify the current mode settings.
Do I need underfloor heating for a Vaillant heat pump?
No, underfloor heating is not required for a heat pump installation. While underfloor heating works well with heat pumps due to operating at lower temperatures, standard radiators are also compatible and effective.
Do I need planning permission for a Vaillant heat pump?
In England, as of 29th May 2025, most air source heat pump installations no longer require planning permission from your local authority. Planning rules still apply in Wales, Scotland, and Northern Ireland, so check with your local authority before installation.
