Here is the third biggest problem in Portuguese houses
Heating and ventilation we have already covered Insulation and Damp in previous posts and coming in at no 3 has to be Heating and Ventilation which is the third biggest problem in Portuguese houses.
With a an open fire in the kitchen to cook on as the sole form of heat there is rarely a stove in old houses. If there is you can bet your bottom dollar its old clapped out and rusty. Not to mention highly inefficient in comparison to modern stoves and possibly leaking carbon Monoxide as well.
leaking carbon Monoxide as well is not such a problem because Portuguese people keep the doors open for most of the day its when you refurbish your property with nice new tight fitting, draft free windows and doors that it can become very dangerous.
If you are going to fit a new wood burner into the property. Think carefully about the ideal position ( ) that way you will get the best from the heat that it delivers, keep your home dry and burn fuel at maximum efficiency.
It is vital that you have Permanent ventilation close to the stove via a passive vent. It is not good enough just to open a window occasionally. Then you have to think about ventilation in the rest of the house to get rid of damp air which causes condensation and black marks on the walls.
A home with no insulation needs ventilation. This can be achieved by fitting passive vents through the outside walls, window trickle vents electrical extractor fans ( as long as they are turned on !)
Ventilation is the process of changing or replacing air in any space to control temperature or remove any combination of moisture, odors, smoke, heat, dust, airborne bacteria, or carbon dioxide, and to replenish oxygen. Ventilation includes both the exchange of air with the outside as well as circulation of air within the building. It is one of the most important factors for maintaining acceptable indoor air quality in buildings.
passive vents through the outside walls provide excellent ventilation. For more information contact Castelo Construction.
