Grant Heat Pump Maintenance

Brook Renewables provides specialist Grant heat pump maintenance for homeowners and landlords across Ireland. Whether you own a Grant Aerona³ air-to-water heat pump or an older Grant system, our SEAI-registered engineers have the expertise to keep your system running efficiently and reliably all year round.

Why Your Grant Heat Pump Needs Annual Servicing

Grant heat pumps are well-regarded systems built for the Irish climate — but like all mechanical systems, they require regular professional maintenance to continue performing as intended. Skipping annual servicing leads to reduced efficiency, higher running costs, and unexpected breakdowns.

  • Keep your Grant 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

Grant Heat Pump Models We Service

How Often Should a Grant Heat Pump Be Serviced?

We recommend a professional service once a year. Late summer or early autumn is ideal — your system is checked and ready before the heating season begins. Grant’s own guidelines also recommend annual servicing to keep the warranty in place.
