Condensation is a tough job, other than a good Dehumidifier which is quite expensive to operate and noisy, too. only if you use the budget models which only suck in the air in the roof space. the better models use external air and some can use both. if its a cold day it will use the warm air under the roof, but switch over to out door vent on hot days. |

Neighbour, same kind of house , no DVS had loads of it. But their place had been modified, it had aluminium windows. So we move here, aluminum windows and doors, the whole insulated, carpet on floors business. So what do I do? The kitchen and bathroom windows are open 365 days a year, albeit not fully in winter. Works well, minimal condensation, in fact none unless cooking, then you get a wee bit. one big advantage of using a ventilation system is you do not need to keep windows open. in fact you need to close them for it to work properly. if you use a lot of ventilation its also a lot of your heat that goes out the window as well. with the balanced type ventilation system they have heat recovery which reduces the heat loss from the ventilation (out going air heats up the incoming air). one of the catch 22's is that you need heat in the home to help drive out moisture from the woodwork and furnishings. but a lot of ventilation reduces the heat. you really want to have no ventilation, heat the house up and then ventilate. |
