We also offer several optional extras which can be fitted to your ventilation system to ensure optimum air quality and/or a more comfortable temperature in your home.


Air-Warmer



The DVS Air-Warmer is designed to pre-warm (or take the chill off) cooler air from the roof space during winter months before it enters the home. This pre-warmed air will not feel hot; it will only be a similar temperature to that already in your home. Even with the DVS Air-Warmer operating, normal home heating will still be required to maintain a comfortably heated living environment and to assist in controlling condensation.

To best manage heating costs, all Air-Warmers feature a time-switch, enabling you to pre-set the time and days of the week when the DVS Air-Warmer will switch on and off. As a further power-saving measure, Air-Warmers fitted to a G3 system can also be programmed to switch on when the roof temperature drops below a certain level.

For energy-efficient operation, G3 and 5E
Air-Warmers automatically adjust power consumption (up to a maximum of 2kW) to maintain the Air-Warmer's output temperature.


Automatic Summer Ventilation

 

The purpose of DVS Automatic Summer Ventilation is to deliver a continuous supply of fresh, filtered air, drawn from outside the roof space, when the roof space itself becomes too hot.


This allows you to ventilate your home with fresh air throughout the summer months - without the need to leave windows or doors open. DVS Automatic Summer Ventilation allows you to reduce pollen, dust, insects and noise, and improve your home's security while enabling you to enjoy a constant supply of fresh, cooler air, day and night.

Automatic Summer Ventilation is only available for a G3 system, which regulates the incoming air depending on the temperature of the outside air and the roof space air, according to your comfort settings on the G3 control panel.

DVS Air Transfer System 

Despite having a perfectly good heating/cooling source in the living area (such as a heat pump), its effects often do not extend to other areas in the house such as the bedrooms. A thermostatically-controlled Air Transfer System will circulate the air from the source room to other targeted areas of your house, eliminating hot and cold spots and providing a comfortable, even temperature throughout your home ... more>


External Air Supply Unit

An External Air Supply Unit draws air directly from outside, rather than the roof space. The air is then filtered before being distributed around the home.

It may be necessary to install an External Air Supply Unit in homes that suffer from damp roof spaces or roof spaces with poor air quality. This is because dry, fresh air needs to be drawn directly from the outside since none can be sourced from within the roof space.

One of our Consultants can advise whether an External Air Supply Unit may be necessary for your home.
