Mechanical Ventilation with Heat Recovery
How Does It Work
An MVHR system works by taking the stale warm air from bathroom’s, kitchens, en-suits etc via a network of ducts back to the heat recovery unit located in the loft or plant room of the building. The ventilation unit also draws fresh clean air in from outside and through a filtration system the warmth from the stale air is passed into the fresh air which is then distributed through another network of ducts into the living areas.
- Continuous supply of fresh air to provide good indoor air quality.
- Reduces damp conditions in bathrooms and shower rooms preventing mold and fungus.
- Elimination of bad odours.
- The filtered air reduces pollen and dust mites which is a great advantage for people with allergies or asthma
- Windows and doors can be kept closed reducing noise pollution and preventing insects from entering the building.
- Reduces heating bills by up to 30% in airtight buildings.
- The Ecocent Air MVHR has an integrated heat pump that functions just like a refrigerator but in reverse. Whilst a fridge extracts heat from food, the heat pump extracts heating energy from warm exhaust air to heat incoming fresh air. If, however, the air needs cooling the coolant circuit is reversed. The heat pump only consumes a few hundred watts of electricity but enhances the heat recovered significantly. If you put 400-460W into the heat pump ventilation unit, then you can expect to get as much as 3-3.5kW of heat energy output.
- The Ecocent Air MVHR is easy to install; as the heat pump is integral there’s no refrigerant line to install and no planning permission to obtain. It utilises android software and also has built-in CO2 and humidity sensors that adjust it’s performance accordingly.
- The ESP Ecocent units are industry leading, innovative hot water supply systems which use a built-in Air Source Heat Pump to scavenge waste heat and make domestic hot water heating highly efficient offering a saving of up 75%. This system can be used in conjunction with solar heating units via the up-grade coils and is fit-and-forget providing highly efficient domestic hot water 24/7. The Ecocent Maxi Hot Water System uses a higher output air source heat pump than the standard range to reduce recovery time and is optimal for high-use applications.
- The Ecocent unit can also be incorporated into the MVHR system, it does this by taking advantage of the MVHR duct work and connecting into it, this saves time and money on installation costs.
