Service for other European boiler brands
Diagnostics and post-warranty service for selected Ariston, Beretta, Ferroli, Immergas, Broetje, Termet and related gas boilers.
Practical support when the boiler is outside the main brand pages
Warsaw properties contain many European gas-boiler brands and generations. I provide independent post-warranty diagnostics for selected Ariston, Beretta, Ferroli, Immergas, Broetje, Termet and other appliances after the full model and condition have been reviewed.
The first question is not only whether a fault can be repaired, but whether the repair is safe, technically sensible and supported by available parts. I explain the evidence, the likely cost and any uncertainty so the owner can choose between repair, monitoring and replacement planning.
Multi-brand service – scope
Fault diagnosis
Ignition, flame detection, fan, sensors, pumps, valves, controls, pressure and hot-water behaviour are tested before parts are proposed.
Maintenance
Cleaning and inspection are adapted to the construction and condition of the appliance, with final operating checks where the model is within scope.
Post-warranty repair
Confirmed components are repaired or replaced when the part, access and overall condition make the work reasonable.
Repair-or-replace advice
Age, safety, efficiency, corrosion, previous repairs and parts availability are considered before a major expense is recommended.
Selected European boilers serviced
Service requests can be considered for selected Ariston, Beretta, Ferroli, Immergas, Broetje and Termet boilers, as well as some related European brands. This does not mean that every model, age or installation is automatically within scope.
Send the complete data plate and photographs before booking. Imported or uncommon variants may use different controls and components even when the front casing looks familiar. For older appliances, parts availability is checked before promising a repair.

Common faults across many brands
Ignition failure
Gas supply, electrodes, flame signal, gas valve, fan and combustion conditions are considered. The same symptom can have very different causes.
No heating or no hot water
Pumps, three-way valves, flow sensors, temperature sensors, plate heat exchangers and controls are checked according to the system layout.
Pressure loss
Visible leaks, expansion-vessel condition, safety-valve discharge and internal components can all cause repeated refilling.
Overheating or short cycling
Restricted circulation, deposits, pump performance, control settings or unsuitable boiler output may make the appliance stop too quickly.
Noise or vibration
Air, a worn pump, fan condition, heat-transfer restrictions and combustion behaviour are observed before a repair is chosen.
Recurring code after reset
The code and exact model are recorded, but live measurements are still required. Codes rarely justify blind part replacement.
A technically possible repair is not always the best decision
For an older boiler, I consider the condition of the heat exchanger, combustion system, casing, hydraulics and controls, as well as the history of previous failures. A low-cost component can be sensible to replace; a major part on a corroded or unsupported appliance may not be.
I do not sell a new boiler during the diagnostic visit. That keeps the discussion focused on evidence. If replacement planning is more reasonable, I explain which installation issues should be addressed so the next appliance does not inherit the same circulation, pressure or control problem.
What changes between brands
Controls and fault logic
The same numerical code can mean different things. Model-specific documentation and the operating sequence are used together.
Hydraulic construction
Flow sensors, valves, pumps and hot-water arrangements differ. Diagnosis follows the actual component layout, not a generic diagram.
Parts support
Availability varies by age and market version. A part is confirmed before the owner is given unrealistic expectations.
The data plate determines whether the visit can be prepared
Send a clear image of the model and serial plate, the complete boiler, display code and the surrounding pipework. Describe heating and hot-water symptoms separately, including pressure changes, noise and leakage.
Do not remove the casing. If you smell gas, close the supply if this can be done safely, ventilate without operating electrical switches and contact the emergency gas service. If water reaches electrical components, switch the boiler off.

One person responsible for the diagnosis
I am Janusz, an independent heating engineer with many years of service experience and qualifications for gas and electrical work. I use professional measuring equipment and explain what is confirmed, what remains uncertain and what can be planned.
This is independent post-warranty service, not an authorised centre for the listed manufacturers. Warranty claims must be handled by each brand’s authorised network. Fiscal documents and a VAT invoice are available. Guide prices are on the English prices page.
Multi-brand service area
I work throughout Warsaw and in many nearby towns, normally within approximately 80 km depending on the route. Visits are possible in Piaseczno, Konstancin-Jeziorna, Pruszkow, Piastow, Marki, Zabki, Legionowo, Lomianki, Otwock and other surrounding locations.
Because uncommon models require preparation, send the data plate before requesting a date. I will confirm whether the appliance is within scope.
Other boiler brands FAQ
Do you service every model from the brands listed?
No. Selected models are serviced after the data plate, age, condition and installation have been reviewed.
Can you repair an older imported boiler?
Sometimes. The decision depends on safe access, documentation and parts availability. Send detailed photographs first.
Can you obtain spare parts?
Availability is checked for the exact model. I do not promise a part before its identification and supply have been confirmed.
How do I know whether repair is worthwhile?
The likely cost, safety, overall condition, age, previous failures and expected remaining life are discussed after diagnosis.
Do you provide annual maintenance?
Yes, for selected appliances within scope. The procedure is adapted to the construction and condition of the boiler.
Are you authorised by these manufacturers?
No. I provide independent post-warranty service. Warranty work belongs to each manufacturer’s authorised network.
