I have to say that I’m very disappointed with the service, I did tell the salesperson that this unit all the way up a 3 storey house won’t help the living room downstairs and I was right, few months after it has been fitted we are having damp again after we have switched off our portable dehumidifier. Complete waste of 1400 hundred quid, I should have stick to our old dehumidifier. Spoken to Envirovent and they don’t realised how noisy this unit is at night if you have it on 3. Also still having condensation on the windows 🙄... so for us this unit or company is a no go and instead a 100 quid dehumidifier would do the job better.
