## Description

Solar Air Heating Air Conditioning Extraction Fan Thermal Solar Panel Dehumidifier Heat Pump Ventilation Dehumidification water Attic roof ventilation OS20 : desertcart.co.uk: DIY & Tools

Review: Also this would be ideal for mobile homes and sited caravans - I bought this as a supplementary heater for my bathroom it’s half the size of this heaters max room size. This heater could be so much better, if the fan speed was relevant to the outside temperature as well as the room or if you could manually adjust the speed of the fan on the thermostat, I believe it would produce more heat also the internal vent cover could be better ( I did try a louvred type though the fan didn’t open them, I’m sure it will on full power ) I’m currently restricting the air flow slightly in a bid to increase the temperature. Looking at previous models, the photovoltaic panel was separate, this to me was a much better option as in my case the sun won’t be shining on the panel after about13:00, ( the fan works better in full sun ), Then I could’ve placed the photovoltaic panel for optimum max sun.
Review: Great product - I've been using this to ventilate a garden office/summer house through the winter and it is very effective. It keeps the air flowing and moisture out. I have had no damp issues at all and have been using it for 6 months now. Setting it on Auto makes using it pretty straight forward as well. Fitting is not beyond a DIYer either. UPDATE I love this product and company! The customer service is exceptional as well. I had a tech issue and it was resolved really quickly and by very nice people. This is how a company should be run

The product it's self is a good sturdy product and I was going to order more but given the fact that I've been hit by additional charges regarding import and clearance I'm disappointed all round unhappy with lack of interest in resolving
