Trickle vents

Theboinkmaster

we live in a new build with trickle vents over windows.

they have the ability to be closed on each one.

in the middle of winter it seems mad to have the heat blasting and cold air sucking out the heat. so I was considering closing most of them?

I understand it's healthier to have good airflow, but would you get that anyway in the house without these....

non closeable vents are required in rooms with combustion sources ie a fire place, stove, gas hob etc... so dont close vents in these rooms if thats possible.

fully closeable vents are not allowed as per the regulations, so even when window trickle vents are closed they should still provide a certain element of continuous ventilation.

im not sure many do though

'Permanent Ventilator: A ventilator permanently fixed in the open position and not provided with a means of closure which eliminates airflow through the device' – TGD-F

fully closeable vents are not allowed as per the regulations, so even when window trickle vents are closed they should still provide a certain element of continuous ventilation.

'Background ventilator: A secure ventilation opening generally located in a wall or window for the purpose of provision of general ventilation, generally incorporating a controllable ventilation grill which can be fully closed' – TGD-F

When controllable vents are used – in a room without a combustible source - there is no requirement for them to provide continuous ventilation when in the closed position.

Background ventilators are required to provide general ventilation.

Perhaps post the definition of general ventilation.

Theres a confliction in the regs, as usual.

Vents (or ventilation) are generally required only during the heating season i.e. winter. Their role is to evacuate the moisture produced within the building before it has a chance to cause issues (mould etc). Close them and you run the real risk of introducing these issues into your home.

Buy a decent hygrometer and keep it in the room so you can adjust the ventilation to maintain safe and comfortable humidity levels (40-60% RH).

The most accurate consumer ones seem to be the ones for use in humidors. A good indicator of accuracy is the ability to be recalibrated.

Digital doesn't imply accurate, don't confuse accuracy with precision.

ill buy a hygrometer and check, thank you

I'd be grateful for any suggestions as to make and model no of a decent hygrometer ( pm me if required by forum charter )

Many Thanks

In reality, how many of these are needed open, I also feel like I may have too many open and I am just wasting energy. Wind whistling through them today!
