Underfloor heating maintenance is easy and here's how

"Wet underfloor heating systems have a number of different ways that they can be installed, but essentially the maintenance requirement for all wet systems is very similar. Flow is key to the performance levels of your wet underfloor heating, and as such, any restrictions to the flow will result in poor performance. Therefore, a standard underfloor heating annual service is recommended as part of your underfloor heating maintenance plan."

"This will include a service engineer looking at all of the filters, checking that none of the safety valves are weeping, and also that the inhibitors and antifreeze additives are all still fit for purpose. If they have thickened in the system, this will mean the pump has to work a lot harder and flow will be impacted. As the underfloor heating manifold is the part of the wet underfloor heating system that distributes the heat"

Underfloor heating systems are less visible than radiators, with manifolds, connecting pipes and thermostats as the main visible components. Wet systems require regular attention to maintain adequate flow, since any restriction reduces performance. An annual service is recommended to inspect filters, check for weeping safety valves, and verify that inhibitors and antifreeze additives remain effective. Thickened additives increase pump workload and impair flow. The manifold contains the most moving parts, so actuators (zone valves) should be checked to ensure they open and close on demand. System balance must be maintained so the correct heat reaches each area. Call a professional if checks reveal problems.
