Change your fan for a Vent Axia Svara! Super quiet trickle flow with boost but most importantly - it is controllable by a smartphone app so you can easily adjust whether it boosts due to humidity or PIR and it is really quick to adjust sensitivity and over-run timer lengths etc! You could over-ride the humidistat when you go to bed so that it doesn’t boost in the night to keep you awake! Here’s a good video I found on YouTube that shows it’s functionality: https://youtu.be/xN_xPbYawYM

Agree with ProDave - keep your ducting taught and make the highest point of the system the fan unit - this will ensure any condensation runs away from the fan unit. I’d use flexible round insulated aluminium ducting for this installation. The ducting can run to the fan unit from any angle, right angles add resistance to the air flow equal to a theoretical Additional metre to your ducting length. The straighter the run can be to the unit the better - take the most direct route you can!

Hi, You need a fan that does 60l/s in a kitchen to meet building regs. The Vent Axia HR200V heat recovery system does 70l/s and may be the best option here!
