Underfloor Heating

At McDermond Gasfitting we’re qualified to service and maintain hydronic underfloor and radiator heating systems.

We maintain and service the following fuel types: Gas boilers, Diesel boilers and Electrical systems.

We have a strong maintenance programme for the service of hydronic systems which Includes the following:

  1. We’ll flush out the heating lines then fill them with a cleaning solution. This solution is left to settle in the system to de-scale the pipes and remove debris from the system.
  2. The cleaning solution is then flushed out of the system along with any debris, leaving your pipes clear and ready to function efficiently.
  3. The system is then re-filled with an inhibitor added in the lines to protect the metal parts from corrosion.

Get in touch with us at McDermond Gasfitting for any of the following central heating services:

  • Re-commissioning of the system
  • Gas/Diesel boiler check
  • Testing of electrical components and controls
  • Testing of actuators and solenoids
  • Flue gas analysis (CO2, CO, O2) and combustion level analysis
