Mechanical Ventilation With Heat Recovery MVHR

Buildings need insulation to conserve heat and reduce energy costs. The air quality in sealed buildings can rapidly fall to an unacceptable level, leading to health hazards through contaminants in the air. MVHR units provide warmer, drier, safer and more comfortable buildings.

MVHR is suitable for energy efficient ventilation in new buildings and renovations. Below is an image of the descrete vents situated around the building which provide the ventilation.

Mechanical ventilation with heat recovery MVHR

The Insulation Problem

Moist and polluted air, if allowed to remain, leads to condensation. This results is streaming windows, peeling wallpaper, damp clothing and bedding and eventually unsightly mould growth leading to permanent damage of the building fabric.

Mechanical extraction fans, with sophisticated sensing systems are often the most cost effective way of controlling levels of indoor contaminants. In order for these systems to work efficiently, a similar amount of air to that extracted must be allowed into the building. A convenient air entry point is not always available leading to reduced ventilation levels.

MVHR - The Solution


An (MVHR) Mechanical Ventilation with Heat Recovery Unit

MVHR units solve these problems in three ways:

  1. Firstly, the extraction of pollutants and simultaneous intake of fresh air balances the air movement.
  2. Secondly, up to 90% of the heat energy in the extracted air that otherwise could be wasted is transferred to the incoming air thereby warming the room.
  3. Thirdly, heat recovery ventilation will dry the excessive airborne moisture, greatly reducing the humidity of moist rooms like bathrooms or laundries.

Advantages Of MVHR

Warmer, drier, safer more comfortable buildings with uncontrolled condensation eliminated.

The microscopic droppings of the house dust mite can cause asthma, rhinitis, bronchial and other allergic problems. Mechanical ventilation with heat recovery can reduce relative humidity to below 70% which inhibits the ideal living and breeding conditions of the house dust mite.

The long term benefit is global. Domestic housing uses a very large percentage of the UK's total energy production so the whole world will benefit from the energy savings gained from using heat recovery equipment, in turn this will reduce the potential of global warming and the greenhouse effect.

Controlled heat recovery meets the demands of today's life style, and sets the trend for the future of ventilation.

Energy Management Systems

The Eco-Driver energy management system monitors and measures building information such as electricity or gas consumption and turns it into information that is graphically represented on screens so that regular stakeholders can understand and engage with the building in new ways.

Suitable for any large organisation with potentialy high energy consumption and waste production such as schools and universities, commercial office premisis, governemnt and public buildings.


Eco Driver data representation

The Eco Driver:

  • Monitors energy usage, water usage business travel and waste production etc
  • Alerts consumers when consumption exceeds targets
  • Prompts action to reduce consumption
  • Provides feedback on success of action taken
  • Engages employees in sustainability endeavours

Vertical Access Wind Turbines (VAWT)

VAWT are suitable for light commercial use through to large residential projects


Advantages Of A VAWT Turbine

VAWT turbines will work in disturbed turbulent wind & so the windier the better. They are very robust and are low maintenance having only one moving part. Micro-generation of electricity through wind turbines is one of the most cost effective of the clean energies, particularly if you have a windy site. Capital pay back periods can often be as short as 2-3 years. Wind turbines are not noisy. The evolution of wind farm technology over the past decade has rendered mechanical noise from turbines almost undetectable with the main sound being the aerodynamic swoosh of the blades passing the tower.


Carbon neutral power generation: a biomass boiler burns renewable fuel to generate hot water for direct use or heating purposes. Biomass boilers are suitable for residential, commercial and even district heat applications. They can be particularly good solutions for Grade 2 listed buildings or other buildings with high heat loss.

About Biomass Boilers

The fuel they burn is in a constant carbon cycle and is generally a waste product from the left over material from other processes. For example, trees are cut down, the "good" wood is used for manufacture and the rest is scrap or waste. The waste is split into two components. The first is used to fuel a biomass pellet production process and the second is converted via the process into pellets. This leaves only a small amount of ash that is put back into the land. New trees are planted to replace the old in controlled forestry management. The new trees grow and remove carbon dioxide from the atmosphere. In return the biomass fuel pellets are burnt releasing that carbon dioxide and the cycle is closed. So, no additional carbon dioxide is generated and energy is produced. Energy enters the cycle from the trees capturing sunlight; nature's solar panels.

Biomass boilers are available for single dwellings for installation in a boiler room and also available as prefabricated container solutions, simple to locate outside existing buildings. They can also be moved to a new location if required. Perfect when conditions in the location do not allow installation in the existing boiler room, or make it significantly more difficult.

Biomass Solutions

Newform Energy have solutions to meet your specific energy requirements from 6kW up to 1200kW. Our installers have experience of all types of installation and provide training to make the transition to biomass as smooth as possible.

Newform Energy offer a comprehensive supply and installation service for biomass boilers. Contact us to discuss your project requirements.

Anaerobic Digestion


anaerobilc digestor - renewable energy system

An anaerobic digester uses micro-organisms to break down biodegradable material. The unit creates a rich bio-gas for energy production. Anaerobilc digesters are suitable for small to large commercial facilities like farms, schools or hotels.

Advantages Of Anaerobic Digesters

Anaerobic digester greatly reduce the emission of landfill gas into the atmosphere. The nutrient-rich solids left after digestion can be used as fertiliser. Almost any organic material can be processed with anaerobic digestion including biodegradable waste materials such as paper, grass clippings, leftover food, sewage and animal waste.
