Frequently Asked Questions

How much does a commercial dehumidifier cost?

A commercial dehumidifiers capacity is generally measured by how many litres of water a unit removes from the air in 24 hours. As a general rule the higher the dehumidification capacity, the higher the price. A 40 litre a day dehumidifier, is about £412 per unit, whilst a mid-ranged unit, which will extract 70 litres a day is £715, and the largest unit, which will do 170 litres a day is £1,705.Features such as an inbuilt water tank or a hose attachment for continuous drainage, hot gas defrosting for lower low-temperature operation are available.All of these prices exclude VAT and carriage to site

What is the best commercial dehumidifier?

This will depend on your requirements – Do you require a unit with in inbuilt water tank? do you want the ability to pump the condensate up and out to a higher level? Does the unit require a built-in humidistat – so that it can automatically come on and off. If the units are to be operated in a colder environment, a hot gas defrost capability is absolutely necessary to ensure that the dehumidifiers run and the coils don’t suffer any damage. We at Flexiheat UK, have solutions for all of these requirements, with our full range of commercial dehumidifiers.

What size dehumidifier do I need for 700 square feet?

Don’t fall into this common misconception that commercial dehumidifiers are sized on a square footage. All dehumidifiers are sized on the volume of the area to be dehumidified, so we require the volume area, as a building could be 10 feet tall (3 metres) of 20 feet tall (6 metres), thus this the volume is dramatically different. So, get in touch with us, and let us know whether you a trying to maintain the humidity in the area, or trying to dry it out after a flood etc, and we’ll let you know the right sized unit for the job.
