Forced Pressure Ventilation System

For severe condensation problems. Usually combine this with some improvement to heating control but a basic clause:

Ventilation system
1.1	Employ a condensation specialist company to design and commission a ventilation system. Throughout the flat, provide: - A Positive Pressure Ventilation system - Provide a condensation control unit fitted to an external wall operated by introducing fresh, filtered air into the property. - In colder weather, the automated temperature sensor must be designed to activate and the unit will gently temper the incoming air to reduce heat loss. - Where condensation is present within a bedroom or lounge environment, boost extract is undesirable and therefore the preferred solution is a Heat Recovery ventilator to provide quiet, trickle ventilation, whilst maintaining up to 80% heat recovery, reducing heat loss and minimising running costs.
Kitchen
1.2	Provide and install mechanical extract ventilation, vented directly to the external air. The ventilator is to be safely connected to the electrical circuit of the kitchen, and to be capable of providing a minimum extraction rate of 30 litres/second if adjacent to a hob or, 60 litres per second if located elsewhere. To be either humidistat or manually controlled.
Bathroom
1.3	Take out the existing insufficient vent and adjust as below: Connect the mechanical ventilation by means of an extractor fan, to be situated in a duct connected to the external air. The fan must have rate of 15 litres/second and be connected to the light switch and have a minimum 20 minute overrun.
Making Good
1.4	Clean down any remaining mould affected walls to main bedroom, living room, bathroom and kitchen and to window reveals and repaint with mould retardant paint.
