14/12/2011 Seven steps to a happy, healthy heat recovery system

Your heat recovery system (MVHR) is working very hard to keep you and your family healthy but it needs a little help along the way!

Here are seven simple steps to a happy healthy system!

Please refer to your operating guide for appropriate cleaning solution.

Step 1: Turn Off Your MVHR

Make sure your system is turned off and unplugged.

Step 2: Filer check

It is important to check and clean your filters every 3 months, as dirty or clogged filters lowers ventilation efficiency.

Remove the filters, if possible, and wipe clean with the sterilising solution, take extra care not to damage the filter. Ensure that you rinse and dry all parts thoroughly, after using the solution. For replacements please contact aftercare@admsystems.co.uk or call 01756 701051, have a note of your unit make and model number to hand.

Step 3: Condensate Drain

At the same time as the filters are checked, we recommend that the condensate drain is inspected for any blockages and that the trap is charged with water. Pour a litre of water into the drain to demonstrate that there are no blockages and that the water runs freely. Clean if necessary.

Step 4: External Intake Grilles/Roof Vents

Check periodically for dirt and leaves which unless removed will adversely affect your system’s performance. During these cold months it is especially important to check as snow or frost can block the external vents.

Step 5: Cleaning Heat Exchanger

Remove exchanger and wash ensuring that the sterilising solution goes in-between the Cell plates.

Step 6: Inspect the Ductwork and Clean Grilles

Once a year, check the ductwork leading to and from your system. Remove and inspect the grilles covering the duct ends, then vacuum inside the ducts.

Step 7: Check Terminals                                                                                                                                        

Check the terminals mounted in the ceiling in each room for dust/dirt, if very dirty remove and wash.

It is recommended that your Heat Recovery Ventilation System is serviced annually. All these checks are easy if you have time, if not, let us worry about it, contact us on 01756 701051.
