Yes you can, but the amount of energy to heat the space hot enough would be inefficient and very expensive. Dehumidification is the only effective solution protect your super/classic car. Our engineers complete a full site survey taking into account external air infiltration before selecting one of our dehumidification units specifically designed for vehicle storage. The unit will work as and when needed based on a pre set moisture target, and as dozens of happy customers will attest, it really does create the perfect vehicle environment. You can contact us directly here.

No, because the relative humidity in the air would also be inside the automotive air chamber causing the deterioration to the car because all they do is distribute this filitered air. They don't actually get to the root cause of the problem. You can read more here.

Heating and ventilation can reduce condensation build up but are inefficient and have limited success. Ventilation can actually make the problem worse if the air introduced into the space has a higher moisture load than the air it replaces. Heating a space is particularly inefficient, especially if the room isn't well sealed. Ultimately, you have to keep moisture levels below 60% RH to prevent rust build up, and with the UK being one the world's most humid countries, that’s not an easy task. Dehumidification is the only method of moisture control that tackles the problem at source, removing the moisture from the air before it becomes an issue. You can read more on how to store a classic car here.

Whilst compressor dehumidifiers only work really well in warmer temperatures (over 20 degrees celsius) desiccant units extract the same amount of moisture in any temperature between one degree and 20 degrees celsius. That's why they are perfect for the UK's average temperature. You can read more about desiccant dehumidifiers on our parent company here.

The idea that placing a cover over your classic car will protect it from the elements is a myth that has perpetuated itself throughout the history of car ownership. The fact is that any rust damage that could happen to your car is a result of the atmosphere that it’s stored in. Rust damage is caused by a high relative humidity (RH) level. Atmospheric moisture always seeks to reach an equilibrium with the materials within it- the effect of this on materials like metals is that it causes rust. You can read the full article here.

Mildew is thin, black, or sometime white, growth produced by mould. This mould are always present in the air and when combined with moisture and certain temperatures cause the perfect environment for growth. Condensation is formed two ways; either the air is cooled to its dew point or if the air becomes so saturated with water vapour, that it cannot hold any more. In short, opening a window will not stop either of these two things. You can read more here.

If you get the level of dehumidification correct, you won't require the infrared heating. By removing the moisture at source, it simply can't condense on cold surfaces. Having worked with high voltage switchgear to protect wind turbines all over the world using dehumification, we can confirm that infrared won't preserve the metalclad. You can learn more on our parent company website here.

No, you only need a humidistat as measuring the relative humidity is essential. One of our AD150 units would be more than suitable to maintain a constant 45%RH in an average garage. It's a compact stainless steel unit that still has all the functionality of our large units including the option to control it via a provided tablet and app. You can learn more about it here.

With the right equipment, you don’t need an airchamber at all as all they effectively do is distribute filtered air, which is why you’ve added the dehumidifier. Materials don’t feel the temperature, only the humidity. A dessicant dehumidifer regulates the humidity between 40-50%RH which is the perfect environment for all the materials/componants that make up a car. You can read more here.

Condensation is the airbourne water vapour that has condensed into a liquid format and deposited onto an exterior surface. If the temperature of an object such as a car, falls below the dew point temperature for the relative humidity of the surrounding air, water vapour from the atmosphere condense into water droplets on it's surface. The dew point varies according to the amount of water in the atomosphere and the relative humidity. In humid conditions, which is a regular occurance in the UK with an average RH at 80%, condensation occurs at higher temperatures. You can read more about condensation here.

If the humidity is too low (<40% RH), leather will begin to crack and RH below 30% is when the issues occur, especially with rubber perishing. That's why your garage needs to be regulated between 40-50% RH. You can read more about protecting the interior of the car here.

When iron and steel are exposed to moisture in the air, ions in the water cause oxygen atoms in the air and iron atoms in the metal to combine, resulting in rust. This is purely a result of the humidity levels rather than having any relation to temperature. Controlling humidity presents a specific challenge for classic car care in the UK, where there’s an average relative humidity (RH) of 80%. When stats show that the best RH for our own health and comfort is 30-50%, imagine what havoc an 80% RH could be reaping on our beloved classic cars. You can read more here.

Ventilation is the enemy of storage as the UK climate is on average 80% RH and is the main risk linked with corrosion, mould, damp, rot etc. Any forced Introduction of ambient conditions is the very first measure we correct in a humidity controlled environment as this actually adds moisture and makes storage conditions worse. A humidity controlled environment must be a controlled space. You can learn more here.

Our desiccant dehumidifcation systems constantly recycles the air, and cleans it. The units contain an air filter which makes a real difference to the quality of the air, and drastically reduces the amount of dust particles. You can read more here.

We recently installed a unit into an oak framed purpose built garage which was far from air tight and yet we are holding a constant 40% RH, even with wet oak beams. The better the seal on the building, the more efficient the system, but we don't expect a building to be air tight. On smaller spaces, such as single and double garages, cibse building guides suggest that you allow for 1/2 an air change per hour. In all honesty, we would need to do a site survey, which is completely obligation free. Its part of our standard installation and sales process. Every installation that we do is bespoke because every garage is different. If you'd like us to take a look then I can arrange a visit. If you'd rather do it with some images and general dimensions over the phone or email, then we can do that too. You can watch the install here.

No, with the right desiccant dehumidification system you don't need an air chamber for your car. You can show off your car in style whilst protecting it. You can learn more here.

The average RH of the UK is 80% (out of 100) which is relatively high when you compare it to the rest of the world. You can read more here.

ASHRAE stands for American Society of Heating, Refrigerating and Air-Conditioning Engineers and was set up by a merger in 1959 to advance human well-being through sustainable technology for the built environment. They are the leading body on relative humidity of which you can find their chart here.

Rust doesn't require condensation to form, it simply requires a humidity of 60% or more. One of the most common questions we get is 'why have I got rust when I don't have condensation'. Our dessicant units remove the moisture from the space and expel it to the outside atmosphere. All materials will allow a certain ingress of external air, its how you deal with it thats key. Heating the space is one method, but it doesn't remove the problem at source, our units do. Keeping a garage heated during winter is extremely expensive just to maintain an RH that may still be damaging your vehicle. You can read more here.

A desiccant garage dehumidifier is the most efficient system to run. You can see the full breakdown here.

There are a number of different types of dehumidifiers on the market. We've done a full breakdown here.
