The Genvex Combi 185 is a passive certified combined heat recovery ventilation unit with air-source heat pump and integrated hot water cylinder. It uses the recovered heat from the HRV that otherwise would be wasted to heat the 185 litre water tank. It is equipped with high efficient supply and extract air fans, and a counter-flow heat exchanger with an efficiency of up to an outstanding 95%. The Genvex Combi can provide heat recovery ventilation at all times, even when the heat pump is delivering hot water, and has a COP (coefficient of performance) of 4.5. It is an all-in-one compact unit, meaning the system’s components are integrated. The air source heat pump heats the supply air and domestic hot water, prioritising the hot water. This appliance takes up just 600 x 700 mm (the space previously occupied by a hot water cylinder) and has a low servicing requirement. The Combi 185's integrated air source heat pump prioritises the production of domestic hot water and will provide space heating when the 185 litre cylinder has been fully charged. The heat pump is able to produce about 380 litres of hot water every day. The hot water cylinder can as an option be connected to a second heat source for example solar panels or a wood burning boiler. The unit is delivered with a F7 supply and G4 extract air filter and Optima 311 control.
The Genvex Combi 185 is particularly well suited to highly insulated homes, passive houses and apartments, where a high heat recovery rate and a low energy consumption are requested. There are two different versions of the appliance, the difference being the size of the compressor. The Combi 185 S is suitable for the smaller apartments/townhouses where lower ventilation rates are required.
An attractive, easy to use and comprehensive Optima 310 Design Controller is included with the appliance for ultimate controllability of your system. Some of the benefits of this superior controller include:
All Genvex appliances meet and exceed 2007 Building Regulations (Part F, ventilation & Part L, energy efficiency). This means that you don’t have to have ugly, draughty trickle-vents in your window frames or noisy and inefficient extractor fans in your bathrooms. Genvex is also listed in the products section of BRE’s passive house website at http://www.passivhaus.org.uk/
No, air-conditioning uses high speed fans and re-circulates about 80% of the stale air in the home, in order to reduce temperatures down to a set level. A Genvex Standard appliance replaces the air in your home with 100% fresh air at all times. In winter it recovers heat and in summer it can bypass this facility, which can result in a slight cooling effect on summer evenings. A Genvex Enhanced appliance not only has the automatic summer bypass, but the heat pump can also be reversed to further reduce the temperature of the air coming into your home by about 2-3°C.
Generally, only one discreet terminal is required in each room of your house (you ignore hallways and landings). However, rooms over 30m² may require an additional terminal.
With a whole house air-change every couple of hours, things in the air that might usually trigger such conditions like Asthma are regularly removed from the internal environment. Each Genvex appliance also incorporates a special pollen filter on the fresh-air intake, to enhance summer ventilation. There is also an optional electrostatic filter, that traps particles down to 0.01microns, fitering out a large number of viruses. Additionally, reducing the humidity of the air will also discourage dustmites from breeding quite so rapidly and they are usually a regular cause of allergies.
No, with the two fans contained within the insulated ventilation appliance, noise from the ceiling terminals is virtually silent.
Your Genvex is highly efficient and designed to run continuously, as it is the most effective way to ventilate your property. There is a control panel to adjust your ventilation requirements with 10 temperature modes per day, a 24/7 timer, optimum airflow settings (supply & extract adjustable in 3% steps) and periodic ventilation boost of up to 6 hours.
