Cooker hood activated by humidity

[Murdochcat]

Then you get into the “noisy fan when I pee in the night” problem.

I’ve always fancied the idea of the fan turning on when the shower is turned on. In fact I thought of this just recently when I spotted a line in the instructions for my new electric shower specifically saying NOT to connect wires for fans to the shower innards.

Icon have a delay start and timer function for such installations

maybe I'll have to trust that everything will work out fine
Ive found Neff hood which is around £200 coz its an old design. However its reputd to be quiet and powerful, so tha will do
Cheers

With an electric cooker the cooker hood just removes smells, with a gas cooker essential to remove combustion products. Due to latter, to have a humidistat could turn off the hood when required to remove combustion products.

Removing moisture is a problem, and often the cure is to reduce the moisture generated or circulated, showers over a bath where the curtain or panel can't seal at the bottom can cause a chimney effect which draws the moisture into the room in general rather than it remaining in the shower area, also poorly placed extractor fans can do the same, really we want the fan to start when shower turned off, so it does not draw moisture into the room.

Humidistats are a problem if they don't start the fan early enough, as by the time they start the fan the humidity has reached a point where it makes the humidistat so wet it takes hours to dry out again, even when the room has been dry for some time.

The heat recovery unit I have never used, it sounds good, and the lack of cold drafts means people are more inclined to use them. But one can lead a horse to water, but you can't make him drink it, and any fan needs an off switch, so the tenant can turn off what he likes.

A heat recovery unit

may get used more than a simple fan, but it can still be turned off.

Our PIR triggered bathroom fan, triggers during the night - it is barely audible in the room, inaudible outside. The little noise there is, you quickly get used to and learn to ignore. PRI's can be set, adjusted, and screened, so they are only triggered by occupancy of a limited area.

I had an Icon 30 (PIR and Humidistat). The delayed start was purely down to the wax activator. It took a few seconds for the wax to heat up and push the piston to open the shutters. The fan started spinning as soon as the PIR was triggered. 5 seconds later, the shutter would open. I don't know about other Icon modules, but the delayed start wasn't designed to give you a few minutes for a pee in peace.

Exactly, I have one. The wax unit failed, and I managed to source a replacement wax cartridge. It only uses the wax unit, as a means to open the shutter, it's not designed to act as a delay feature - the alternative method is to use a solenoid, or a motor to open the shutters. The wax unit, is completely silent in operation.

I think the delayed opening sticker only exists to prevent people phoning Icon and complaining about the delayed opening (mistakenly thinking that it is faulty).
