I need a need dehumidifier for a cold house. The zambesi has lots of functions especially the timer. However I don't know if it will last considering how expensive it is. I see some reviews say its good, some say it stops after warranty. Help please as the house is victorian with little insulation. I would need a dehumidifier that can really pull the water out. Also do you know how much it costs to run per hour in the UK?
