Chances are you haven’t checked your sub-floor space in a few years. Perhaps are you’re looking around online because you’ve been told you're sub-floor has seen better days!

A sub-floor (or underfloor) is liable to get damp & musty if left unchecked.

Without Sub-Floor Ventilation, you risk:

  • Mould, mildew or fungal growth,

  • Rising damp & condensation problems,

  • Rotting floorboards & foundation stumps,

  • Damage to internal walls & paintwork,

  • A perfect breeding ground for white ants, termites & borers!

High moisture levels can lead to irreversible damage to the structure of your house. Repairing your sub-floor space is no cheap fix—so why risk having problems in the first place? If you have high humidity, poor indoor air quality, you’re risking the health of the home occupants.

Solar Whiz offers powerful solar sub floor ventilation. We’re serious about protecting & safeguarding your home’s sub-floor. Don’t risk your greatest investment becoming an expensive repair job—no home sub-floor should be a problem.



Premier Property Services offers a wide variety of fans, each suited towards extracting different volumes of air. Every home is different—some large, some small, some with lots of sub floor space, and some with none at all!

We offer a variety of fans, each of different sizes & ventilation capacity. We understand that sub floor vents need to cater to a wide variety of homes. In the scenario one of our fans doesn’t fit, we can also make use of our other inline fans to tailor a sub floor vent solution just for you!

Our fans are connected to roof (or even wall-mounted) Solar PV cells. These ensure that your system runs when you need it most, and can even run in low-light conditions like overcast weather! If a Solar-style setup doesn’t suit, we can even set up a 12-volt power pack plugged into a 240-volt power point for underfloor ventilation all day long.


    Run every day,         costing nothing at all

The SAV2.5GB is a compact solar powered extraction fan that offers an impressive 450 m3/hr extraction rate. The fan would be ideally positioned on a north facing wall to maximize exposure to the sun. A perfect compact solution to ventilating a shed, greenhouse or even a sub floor area.

Solar sub-floor ventilators are reliable, quiet and fully automatic

Runs all sunny days, and will completely dry out the sub-floor area


  • Is it damp under the house?

  • Are the foundations damaged?

  • Do floorboards move or squeak from rotting timber?

  • Are you encouraging termites? 

  • Is there an unpleasant smell from the damp under floor?


 Five common sub-floor problems eliminated by effective solar-powered ventilators:-

• Horrible, mouldy smells.
• Rotting floorboards & stumps.
• Damage to internal walls & paintwork.
• Crumbling brickwork and foundations.
• Breeding ground for termites, white ants & borers.

The sixth is far more serious:-

Permanent bad health, from breathing in harmful mould spores by you and your family.


Solar sub-floor ventilators pass warmer, drier, outside air through damp sub-floor areas, to dry out the moisture that causes damage. 

  • Fan operates during daylight hours only, when the fresh air is warmer and drier, rapidly reducing moisture under the floor.

  • Dampness under the floor will be completely removed, so long as any new water flow is stopped.

  • Once dried out, the problem is gone forever.

  • Why pay to operate the fan, when the sun can do it for free?
