Whether you own a Vaillant aroTHERM plus Monobloc or a flexoTHERM system, our SEAI-registered engineers have the expertise to keep your system running efficiently and reliably all year round.
Why Your Vaillant Heat Pump Needs Annual Servicing
Vaillant heat pumps are premium systems with a strong reputation for build quality — but regular professional maintenance is essential to keep them operating at the standard they were designed for. Without an annual service, efficiency falls, energy bills increase, and minor issues can develop into more significant problems.
- Keep your Vaillant manufacturer warranty valid
- Maintain the efficiency your system was designed to achieve
- Catch small faults before they become costly repairs
- Extend the working lifespan of your heat pump
- Reduce energy bills and ensure reliable heating through winter

How Often Should a Vaillant Heat Pump Be Serviced?
We recommend a professional service once a year. Late summer or early autumn is the ideal time — your system is fully checked and ready before the heating season begins. Vaillant recommends annual servicing to maintain warranty cover and ensure continued system performance.
