Electric underfloor heating is relatively maintenance free. Once the electric floor heating cable in in the floor it is difficult to damage, unless to drill a door stop in the floor!
Hydronic underfloor heating does require ongoing maintenance. Ideally, hydronic heating systems are checked at the beginning of the cold season before turning on.
Water pressure in the system is checked and may require topping up, along with cleaning pumps fans, terminals and Y strainers.
Comfort Heat offers and annual system service check if located in the Greater Sydney region.
