Constant running fans have been around for a number of years but are becoming more prevalent as changes to house building, regulation and the increase in home insulation have all conspired to reduce the amount of natural ventilation (air leakage) that occurs in our homes. This is of course intended but a side effect of wrapping our houses up so they stay warm is that they don’t ‘breathe’ like they used to.
These are super quiet fans that work continuously in the back ground to ensure air is changed, keep the air fresh and stop any mustiness and damp occurring. They are also super efficient costing just c.£1.50 per year to run. They are particularly suited for problem rooms, bathrooms/en-suites and toilets that do not have windows. They are the latest technology for damp and condensation control.
