If we preserved our home totally, we be supposed to only get fresh air inside when we opened a door or window. We need ventilation to exhaust unwanted smells, water vapour and contamination, and restore them with clean air, but we also need to control ventilation natural so that we can turn it on and off as we need it, and direct it where it is necessary. In this way we can prevent the waste of heat in the way that water is exhausted through drenched taps. We then merely lose the heat in air allowed to run away for ventilation purposes.
Conventional wisdom has recognized that an average-sized room requires at least one air change per hour when occupied. nevertheless this varies and is dependent on such factors as the figure of occupants and the number and nature of the sources of pollution. Traditionally, ventilation was achieved with the use of air bricks and infiltration; however, as our energy conserving becomes more complicated, we require to develop a correspondingly more sophisticated ventilation strategy.
everlasting ventilation for combustion
It is a statutory condition that heating appliances which require air from inside a room for safe operation should have a permanent ventilator. The danger is that the fuel does not burn efficiently without sufficient oxygen; if toxic products of combustion are not exhausted, they can build up in a room and possibly prove fatal. In old houses the original ventilators are often papered over and it is obviously important that either they are unblocked or an option route is found for the incoming combustion air. One way of providing this option route is via a purpose-built duct delivering air directly to the appliance.
Heat exchangers
Is there any way we can save the heat lost through prohibited ventilation? Heat exchangers are designed to do now this. They are a relatively new method of recovering the heat from warm air before it is exhausted to the outside, and are being used increasingly as part of an overall strategy for ventilation and energy protection. The standard is simple: the sociable air is extracted through a matrix of hollow tubes and fins which temperate the incoming air controlled within them. In better system, warm air is composed via ducts from various places around the home, such as bathroom as well as kitchens, and the warm fresh air is delivered to the living rooms.
Your ventilation policy
Once you have identified individual problems in each room of the home, such as a warmer requiring combustion ventilation or a room with too much humidity, it is essential to draw up a ventilation plan. maybe the most significant decision you should make at the very opening is whether to install a warmth exchanger with ducts to various parts of your home. If you make a decision this then the problem is more or less solve in one go. This should be the nearly all energy-efficient alternative. If not, consider all the measures below and try to constancy the air flow in each space of the residence so that you have an inflow and an outpouring. If this seems complex, continue and find ways of simplify the difficulty in your mind: for example, if you fit controllable trickle ventilators to all your windows, go away gaps nearby the internal doors and install extractor fans in the bathroom and kitchen, this would be suffi¬cient. You will of course forever have the option of simply opening window as essential. It is up to you how sophisticated a system you devise. keep in intelligence that in a tall home in very cold or very windy weather, what system you contain will need to be closed right down as the force differences will force air through much smaller openings.
• make a decision whether to install a heat swap system.
• Fit convenient drip ventilators in each room to get cross ventila¬tion (the ease with which these can be fitted to obtainable windows vary with the type of window).
• Ventilation strategies.
• Install automatic extractor fan in kitchen and bathroom, prohibited by a timer or humidistat (moisture control switch).
• Install permanent ventilation intended for incineration appliances which rely on a supply of air from inside.
• Use defunct chimney as channels for airing or ducting. This may be particularly useful if it is difficult to fit ventilators to the windows. Consider also using your chimneys to recirculate hot air to upper storeys or vice versa.
• Install air-cleaning measures: either mechanical or organic, ionisers or filters. If the main problem is humidity then consider using a dehumidifier and if lack of moisture then believe a misting humidifier or again the use of plants.
