Hi
I'm looking for advice from anyone that has a Itho (Heatrae Sadia) Hru Eco 4 fitted in their home?
We moved into a property in 2018 with 2 units (dating from 2010), both were serviced last year but we recently noticed that the discharge fan in one of them is no longer running smoothly and as a result, creating more noise and subsequent lack of air flow through the ducts.
We ordered a new fan but we have exactly the same issue - the fan sounds like it struggling to maintain a constant speed. Any thoughts? We're trying to find an engineer who can come and look at it at the moment but no luck so far!
TIA
