Heat Recovery and Ventilation

Heat recovery captures waste heat energy and reuses it by returning it to systems or processes.

The cost benefits of a heat recovery system depend largely on the type and scale of the installation, but heat recovery can give substantial long-term energy savings. It often reduces the need to generate heat in the first place, making further energy and cost savings.

Whole House Ventilation System

The SAP Q eligible CVE ECO 2 is one of the most versatile and efficient MEV products on the market adapting to any situation. Continuously extracting the contaminated damp air from all wet rooms, this compact unit ensures regular, controlled, energy efficient ventilation.

Buildings suitable for CVE ECO 2 installation:

• Residential buildings
• New builds
• High and low rise buildings
• Renovations

Helping to lower CO2 emissions, the CVE ECO 2 is equipped with low consumption DC motors that ensure the unit functions with a much higher efficiency than ‘conventional’ MEV models. Hidden away in the loft or cupboard, this individually adjustable system comes with a three-speed RF remote control switch but is also available with a two-speed hard wired version.

Tested on a kitchen plus up to four wet rooms, the unit fully complies with System 3 of the Building Regulations Approved Document Part F 2006: Means of Ventilation (England & Wales), BRE Digest 398 (Scotland) and the Energy Saving Trust’s “Demonstrating Compliance – Best Practice (2006 edition)” as referenced in The Code for Sustainable Homes.

Heat Recovery System

The SAP Q eligible HRU ECO 4 combiflow whole-house ventilation system is one of the most energy efficient systems on the market. Offering a heat recovery of up to 93%, the unit transfers heat from the extracted contaminated air and fuses it into the incoming fresh air in order to maintain optimum temperatures.

Buildings suitable for HRU ECO 4 installation:

• Residential buildings
• New builds
• High and low rise buildings

Buildings not suitable for the HRU ECO 4:

• Renovations

The triangular formation of the synthetic heat exchanger offers maximum surface area for heat to be transferred and this combined with its quiet energy saving DC motor, makes for an incredibly efficient system.

Tested on a kitchen plus up to 7 additional wet rooms, the unit can be easily installed into a loft space and is controlled by state-of-the-art 3 speed wireless controllers.

Designed to adapt to any climate, the system is equipped with an integrated, fully automatic Summer bypass valve when the exchange of heat is no longer necessary, along with a frost protection device that adjusts the fan speed and combines fresh incoming air with the warmer air surrounding the unit to prevent the system from freezing.

Exceeding the Building Regulations Part L (conservation of energy in homes, offices and other buildings), fully complying with System 4 of Part F (Means of Ventilation) and complying with the improved standards as set in the Energy Saving Trust “Demonstrating Compliance – Best Practice (2006 edition), the HRU ECO 4 RF is an advanced system that is perfectly suited to meet the increasingly challenging targets set by the Government.

Roof Ventilators

The CAS ECO 2 range of roof ventilators offer central extract ventilation from all wet rooms. Extracting air from multiple locations, the central unit is located on the roof where all contaminated air is released. Identified by its flat design and low construction height, the unit has been specifically designed to a height of just 25cm to avoid it being seen from ground level.

Buildings suitable for CAS ECO 2 installation:

• Medium and high-rise residential buildings
• Commercial buildings
• Renovations

Installation is quick and easy and the units require minimum levels of maintenance due to their design. Containing a quiet DC (direct current) motor, the unit is extremely energy efficient, can be easily attuned, offers maximum user control and is future proof.

System Cooker Hoods for use with Ventilation and Heat Recovery Systems

Offering the ideal solution for homes with a central mechanical ventilation system, HR system cooker hoods ensure the efficient extraction of cooking odours and excess moisture for a healthier indoor environment.

As the kitchen is one of the most central rooms in the house a number of daily activities are undertaken here. Without adequate extraction of the contaminants that build up from these every-day activities, the indoor air quality can reduce dramatically.

Not quite classed as a motorless hood nor as a recirculation hood, the HR cooker hood is a unique design that offers unbeatable extraction. Provided with a unique supplementary fan that creates an air curtain around the hob the vapours remain under the extractor hood allowing the central ventilation system to work to its full potential.

Extracting more than 80% of the cooking vapours directly via the central ventilation system before they have a chance to build up and become a nuisance in the home, the HR cooker hoods offer a vast improvement from the general extraction achieved by most motorless hoods of just 35%.

With its quiet, low consumption DC motor, the unit is highly energy efficient, emits low sound levels throughout its use and is available in a choice of stylish designs making the kitchen environment a much more welcoming space.
