Modern living has now become increasingly energy conscious, and with the Government’s ambitious target to reduce carbon emissions by 57% by 2030 on 1990 levels, energy efficient products such as the heatSava are helping to address the reduction in energy wastage.
It is important to recognise, however, that by sealing up our homes, making them warmer and more energy efficient, we must ensure that we sufficiently ventilate them to maintain good, healthy indoor air quality.
The heatSava is an energy efficient, throughthe- wall mini ventilation unit called a Single Room Heat Recovery unit (SRHR). It has been designed for people who are looking for new and innovative ways to save energy.
Recovering up to 75% of heat from the air that would normally be lost through extraction, the heatSava reduces carbon emissions, whilst providing continuous all year round ventilation.
It is available in 100mm and 150mm for mounting through external walls in WCs, kitchens, bathrooms and utility rooms, to either replace existing extract fans or for new installations.
The heatSava extracts air from the kitchen or bathroom, which passes over a high efficiency tubular heat exchange cell. The unique design of the cell enables the air to cyclone around the barrel, just like a corkscrew.
As it does so, the heat from the extracted air is retained in the cell before it reaches atmosphere. At the same time, fresh air from outside is supplied through the tubes, collecting up to 75% of the heat from the extracted air before returning it into the room, providing savings on energy costs.
The heatSava runs continuously 24 hours a day on a low background trickle rate to provide constant all year round good indoor air quality, controlling humidity levels and reducing condensation.
Within the heatSava, EnviroVent have applied a technology found in early 20th century steam locomotives. In its original form, steam passed through ‘fire tubes’, transferring through the tube wall into the water. By heating the water to high temperatures, steam was generated. Instead of water and steam, the heatSava utilises this same principle for air.
It extracts waste heat from the property, which is transferred through the tube wall to heat the incoming fresh air. At best a locomotive would be 30% efficient, however with modern materials and improvements to this technology the heatSava can now achieve up to 75% efficiency.
The heatSava is IPX4 rated and can be installed in Zone 1 with RCD protection. It can be quickly and safely converted to an SELV version on-site when necessary with the use of the separate power supply unit included.
The direct replacement of an existing traditional extract fan can be simply and quickly achieved, whilst the innovative design also allows the unit to be installed to uneven walls.
It is also high-rise friendly, easily installed from inside the building, without the need for scaffolding. It can be installed in four different positions through 360°, horizontally or vertically to fit into tight spaces or where an existing hole is located just below the ceiling. With its stylish symmetrical design it looks attractive in any position.
The bi-product of any high efficiency heat exchange cell is condensation. This presents a challenge to design engineers to ensure that any condensate which forms inside the cell is directed outside the property and not inside the product, where it could mix with electronic components or damage decorations inside the room.
The unique design of the heatSava allows the heat exchange cell to be completely sealed within the cell casing, providing a totally air tight compartment.Should any condensate form, it would be held within the barrel and drain out directly to atmosphere through the holes located in the cowl at the rear of the unit.
The unique configuration of the air movement through the cell means that no condensate can form within the tubes resulting in all year round quiet, high efficient performance.
No matter how many different house types and how many different wall depths, the heatSava has it covered.
The heatSava is available in two cell diameters: 100mm for bathrooms and WC's and the 150mm for kitchens, ideal for both refurbishment and new build installations.
Fitting neatly into almost any wall depth, the length of the cell is available to suit external wall depths of 310mm, 430mm, 500mm and 600mm.
The heatSava is the only unit on the market to be 100% balanced across both extract and supply airflows, operating in perfect symmetry to achieve optimum performance and efficiency in accordance with current EU Single Room Heat Recovery test methodology.
The tubes have been intelligently engineered with a twist through 15 degrees. This increases the dwell time that the air cyclones around the barrel, improving thermal efficiency. The heatSava has undergone rigorous and extensive testing in world class laboratory facilities.
The heatSava can be easily cleaned and serviced completely hassle-free by the resident by vacuuming the side of the grilles to maintain efficiency and performance.
For ease of servicing by maintenance personnel when the front cover is removed the unit will stop operating to allow the unique plug out/plug in heat exchange cartridge to be removed using the service key provided. The cell can then be simply vacuumed or wiped clean with a cloth.
The heatSava incorporates a time elapse meter as standard to monitor operational life.
