Ventilation & Heat Recovery Systems

Ventilation Heat Recovery Systems – Due to our vast experience in the remedial industry we recognise the importance of good ventilation and heat recovery systems, and our service in this regard is second to none.

Types Of Ventilation

Positive Input Ventilation (PIV)

Our PIV systems are sophisticated whole house ventilation and condensation control units which have BBA certification and also comply with building regulations.

The PIV unit works by drawing in fresh, filtered and clean air from outside, that gently ventilates the home from a central position on a landing in a house or the central hallway in a flat or bungalow.

The integral pre-heater is designed to temper the incoming air during periods of low external temperatures. A sensor monitors incoming air and slowly pulses the heater to ensure temperatures are held to pre-set minimums. For monitoring of operational life and verification of usage, an integral Hours Run Meter is fitted.

Mechanical Extract Ventilation (MEV)

The MEV is a low energy, continuously running whole house extract ventilation unit with multiple extract points to simultaneously draw moisture laden air out of the wet rooms of a property, whilst minimising the migration of humidity to other rooms.

Mechanical Ventilation with Heat Recovery (MVHR)

MVHR systems work by extracting the stale, moist air out of the house or a utility room or cupboard in an apartment. Simultaneously, fresh air is drawn into the unit from outside via a filter and is warmed by the high efficiency heat exchange cell.

This tempered, fresh air is then delivered through supply vents into the living, dining and bedroom areas. This system maintains a stable humidity level, free from condensation and mould.

Extract Fans

Our high performing and very quiet extract fans reduce humidity levels at source and improve indoor air quality, combats window condensation, damp and mould problems.

We offer a wide range of high performance, energy efficient and innovative ventilation systems that are designed to deliver homes with fresh, filtered air by providing a permanent solution to unnecessary condensation and mould problems whilst being easy to maintain. Our site survey will recommend the most appropriate and cost effective solution.
