The first thing to consider is whether you have a roof space or loft, or not, so if you live in a house or a bungalow with a roof please click here
and if you live in a flat or an apartment without a roof – you’ll find solutions here

Condensation control in bungalows

Bungalows are prone to mould, must and damp especially in the corners of colds rooms. We recommend the Drymaster Heat as the best solution.

Along with introducing a gentle flow of clean, dry air into your home it has a heating element which switches itself on when the incoming air is below a set temperature: on cold nights, cool air can be uncomfortable in a bungalow.

If you have a limited budget the Drymaster Standard is the best buy and we have many happy customers using this system.

Other products can be useful additions to a PPV especially if the kitchen or bathroom is not ventilated. If the bathroom and kitchen are close together a HRV would be very effective installed in an outside wall. You may have special problems in remote rooms or e-suite bathrooms in which case click here

Condensation control in buildings with a roof void.

The key to all condensation control is ventilation. Good ventilation systems should be automatically controlled and cheap to run. Some systems actually input energy from the sun - heating the home for free. These are usually known as Positive Pressure Ventilation systems - PPV.

Your home can be ventilated with 'dry' air directly from the roof – the filtered air is introduced through a diffuser and mixes with the 'wet' air in your home: the mixed damp air then gently leaves the building via cracks and crevices solving the damp problem. On warm or sunny days, even in winter, the incoming air is tempered by the sun. In your home we recommend a Drymaster Standard is fitted above the stairwell. The Drymaster Standard will switch itself off when the roof air is hot. Thus saving energy. Positive pressure ventilation is also known as PPV, PIV,PPI and ACU.

To maximise energy saving the Drymaster Eco 2000 model has the added feature of a remote temperature sensor which runs the machine whenever a remote room is colder than the air in the roof.....free solar heating for a cold spare room.

The Drymaster Heat as it not only introduces a gentle flow of clean, ‘dry’ air into the home it also has heating element which switches itself on when the incoming air is below a set temperature: on especially cold nights in winter, the tempering of the incoming air is an added luxury.

Mould killers, special paints, double glazing, damp proofing, draught proofing and insulation will not reduce humidity in the home.

Switched or timed fans with no humidity control will either over-run, wasting energy, or not run long enough to solve your problem.

Dehumidifiers are very expensive to run, noisy, take up floor space and must be emptied frequently…..they are not recommended to control anything but the most localised problem.

Condensation control in homes with no roof or with poorly ventilated kitchens and bathrooms

We recommend you install one or more Heat Recovery Ventilators, HRVs, in the kitchen or bathroom. The damp air inside the house is exchanged for dry air from outside: 80% of the heat which would otherwise be lost comes back with the new 'dry' air via the heat-exchanger. These units are very energy efficient, use 40watts on boost, and reduce the humidity automatically. HRVs give some background air flow at all times and conform to F1 of Building Regulations. HRVs may be used with positive pressure or humidity controlled fans where special problems are found.

Humidity Controlled Fans, HCFs, expel damp air and switch off when the humidity is low enough to stop condensation. They are cheaper to buy and fit than HRVs but not nearly as effective – such fans can be fitted through a ceiling ducted outside. HCFs can be fitted into the same hole as an existing fan and often using the same power supply making them very low cost to install. HCFs can be installed in addition to positive pressure or heat recovery ventilators where exceptional problems are reported. e.g. in the ceiling of a remote en-suite. Dryhomes stock a small range of HCFs to suit all budgets – the more you spend the better the build quality, they will be quieter, more powerful, better controlled and more effective.
