The homevent provides whole home ventilation using the Positive Input Ventilation principle. Essentially the concept is to introduce fresh, filtered air into the dwelling at a continuous rate, encouraging movement of air from inside to outside.
To achieve this, the unit is mounted in the loft space, drawing air through the filters and inputting it, at ceiling level, into the property.
The homevent units are fitted with an internal temperature sensor. This sensor continuously monitors the temperature in the loft, boosting the air volume when the loft temperature is above a set level (heat recovery mode).
If the loft temperature becomes excessive the unit will switch to standby mode (no airflow). Once installed, the airflow can be set to suit the house size and, if required, the way it responds to the temperature changes within.
The homevent unit incorporates an integral heater which can be set to provide additional heating of the incoming air if required e.g. during very cold weather. The heater can be used to distribute filtered, warmed air throughout the property.
Check to ensure that the loft has adequate ventilation. Look for ridge vents, tile vents, eaves vents and continuous air gaps etc. making sure none are blocked. In older properties these vents may not be provided. However, there should be enough ‘leakage’ to accommodate the requirements of the homevent unit.
A useful way of checking such lofts is to close the hatch, switch off the lights and look for any daylight penetration. If you can see daylight it is reasonable to assume that the loft has ventilation.
There may be occasions where a loft is so well sealed that additional ventilation may have to be provided by the owner/ occupier. This will not only assist the operation of the homevent, but will help prevent possible expensive structural damage caused by inadequate air movement in the loft itself. It should be noted that there cannot be too much ventilation into the loft.
- Ensure that all water tanks are covered and sealed
- Check that all water pipes are lagged.
- Ensure that any extract fans are discharging to outside and not into the loft.
- Check that the loft hatch is tightly sealed.
- Ensure that all holes in the ceilings are sealed i.e. ceiling light fittings etc.
- A visual inspection of any flues or chimneys for leakage in the loft should be carried out by the installer.
- If any leakage points are found, or if there is any doubt at all, then the installer should advise the house owner/ provider as soon as possible and seek instruction from them before proceeding with the installation.
Condensation .. it's causes and effects.
Water is deposited on the cooler surfaces in a building, particularly in winter. The first indication is usually black mould growth in the worst affected areas. This growth is characteristic of condensation because mould need pure water for their growth and development. In severe cases the amount of water may be great causing pools of water on the floor, windowsills or on clothing and furniture.
Householders often find it difficult to believe that such severe damp problems can be caused by condensation alone. Often they believe there must be some sort of building defect which is usually not the case.
Often the condensation can occur at low levels where the surface of the wall is coolest, starting in a corner and then spreading along the length of the wall. This may appear to be rising damp and can easily be confused.
Why has condensation become such a common cause of damp?
If the water vapour in the air of a home can escape somewhere, condensation would never occur. When homes were more draughty and open fires common, damp air would mainly escape up the chimney. Houses are now significantly better insulated hence the moisture has nowhere to go and hence condensation problems have grown significantly.
Mould growth is a typical consequence of condensation problems in a home. Moulds are often most severe in room corners and on external walls. This is mainly because insufficient ventilation creates pockets of stagnant air in such corners.
