Mechanical Ventilation with Heat Recovery (MVHR) is a whole house ventilation system that both supplies and extracts air throughout a property. Heat recovery is an option used in domestic dwellings, and helps a to reduce the heating and cooling demands of buildings.

Heat recovery systems typically recover about 73–95% of the heat in exhaust air and have significantly improved the energy efficiency of buildings.

MVHR is the ideal choice when:

• You are doing a full renovation or building a new house rather than a retrofit.
• You require a whole house ventilation solution.
• You want to make your home energy efficient.

Mechanical Extract Ventilation (MEV) refers to both centralised and de-centralised systems which provide ventilation helping to reduce excess moisture using either a multi-point extract or single fans in wet rooms. MEV systems provide year-round good indoor air quality, protecting your home from condensation, damp, and mould. EnviroVent MEV systems also come with a 2 year guarantee, giving you peace of mind when purchasing.

MEV is required when:

• You are doing a full renovation or building a new house rather than a retrofit.
• You want an easy to install, whole house ventilation solution.
• You want a fit and forget solution.

Extractor fans are a functional and practical solution for controlling excess humidity, smoke, heat removal or unwanted odours. Fans for bathrooms are generally smaller than those used in kitchens but do come with a timer for more efficient use.

A bathroom is a damp room by definition, so providing proper ventilation is imperative, both for the occupant's health and for the bathroom itself. Renewing the ambient air limits the emergence of any condensation and the appearance of mould all the while reducing the humidity level.

Replacing your fan will improve the ventilation of a bathroom or kitchen and reduce moisture and unwanted odours. Our range of high-performance, efficient systems designed for bathrooms and kitchens includes inline, wall-mounted, and silent extractor fans as well as axial fans.

Positive Input Ventilation (PIV) also sometimes known as positive pressure ventilation work as a whole house ventilation system and create fresh and healthy living environments by supplying fresh, filtered air into a property at a continuous rate throughout.

Ventilation is mainly used to control indoor air quality by diluting and displacing indoor pollutants; it can also be used for purposes of thermal comfort or dehumidification. Positive Input Ventilation or PIV Systems work by encouraging the movement of air from inside to outside from a unit that is usually installed in a loft. These units reduce or eliminate surface condensation altogether by replacing humid stagnant air with fresh filtered air.

PIV is recommended in situations where:

• You don't want to do a full renovation.
• You require a whole house ventilation solution.
• You don't want to remove any walls or go back to brickwork.

EnviroVent believes that quality ductwork should not be dependent upon highly qualified installers and regulatory measures.

Therefore, we introduced ventilation ductwork, which can be installed very easily and quickly, even by less qualified and experienced installers and is air tight by definition

The Fast Track Thermal Range is a comprehensive portfolio of ductwork and parts to make complete, energy-efficient and easy to install ventilation systems. The ductwork is available in circular sizes of 125mm and 160mm and rectangular dimensions in sizes 204x60mm.

 The essential DF multi-cone architectural diffuser is ideal for standard lay-in most commercial projects requiring versatile high quality diffusers for integration in any ceilings. 

 Waterloo Air Products range of fixed & adjustable blade swirl diffusers presents an attractive and aerodynamically efficient alternative to conventional circular or square ceiling air terminals. 

 The Waterloo small format continuous slot diffuser series CS has for many years set the industry standard in terms of highest aerodynamic and acoustic performance.  

Beautiful

The FLOWBAR system satisfies the requirements for designing an air distribution system that will maintain optimum room air conditions whilst becoming an integral component of the architectural concept of the project. In hard ceiling applications, a totally hidden appearance can be achieved with only a small slot opening.

 A small & large circular multi-purpose diffuser designed to produce horizontal or vertical air pattern, with a compact and robust build. 

 The Waterloo WDJ Drum Jet diffuser is a high capacity unit specifically designed for  warehouses, sports halls or factory units etc where a long throw is required. The WDJ is fully adjustable to provide a full jet spread and directional control.

RWH - Hi-Flo

EBD - Eyeball

 The LCT20 has been developed for use when mounted directly on top of a 20% open area ceiling tile. The diffuser is supplied in matt black as standard and the outer flange has a black gasket to seal against the back of the tile and offers a high induction effect. 

  A range of high quality valves for supply and exhaust applications for commercial and industrial projects. Series V valves are best applied to air distribution systems handling relatively low air flow rates within small circular ductwork. The valves provide high initial resistance with wide throttling capability which is necessary to offset the relatively high system resistances. 

 The Waterloo Aircell WFO series floor diffuser offers the choice of horizontal or vertical air patterns with its flip over design, as well as a host of other unique & patented features.

The WFOV low pressure vertical supply disc offers vertical projection with a 50% increase in air volume capacity, compared with standard WFOR units.

• Robust sheet steel design
• Manages air flows substantially below room temperature
• High induction rate
• Cleanable
• ALS commissioning box with damper function or dirt trap LOCKZONE T as accessories
• Standard colour Grey RAL 7037
  • 5 alternative standard colours
  • Other colours upon request

 Low velocity terminal for small air flows

The DPGa is a circular low velocity terminal designed for small air flows Air is supplied to the room at low velocity. Suitable for rooms where a number of small diffusers can be placed in different locations for the best possible distribution of supply air, for example large public assembly halls, theatres, cinema auditoriums, lecture halls etc. The diffusers are mounted under chairs in the risers of the floor. The space below the floor is used as a pressure chamber. The terminal may also be used as a traditional wall diffuser with excellent results.

• Suitable for terraced seats
• Fixed spread pattern
• Simple installation
• Requires no maintenance
• Cleanable
• Suitable also as traditional wall diffuser near ceiling
• Standard colour Black RAL 9005
  • 5 alternative standard colours
  • Other colours upon request

 Low velocity terminal for small air flows

DRG is a rectangular low velocity terminal designed for small air flows, the air being supplied to the room at low velocity The spread pattern is easily adjustable with the rotatable discs. It is suitable for rooms where many small units can be spread out for the best possible distribution of supply air, for example in assembly halls, theatres, cinemas, lecture halls etc. The unit is mounted under seats in the riser of the steps.

• Adjustable spread pattern and affected area zone
• Simple to install
• Cleanable
• Available in a large number of special versions for optimum adaptation to the room
