NuTech IRES SystemThe unique NuTech IRES System combines the benefits of a solar hot water system, a heat recovery ventilation system and an air heating system in one.
Benefits of NuTech NuTech IRES System ?
The NuTech IRES tackles two of the three thirds of Energy Demand for Space Heating, Ventilation and Hot Water in a Low Carbon House.
The three thirds being;1. Heat Loss through the fabric i.e. walls, floors, windows and roof2. Heat Loss associated with air infiltration, which is necessary for ventilation3. Heat Demand to provide Domestic Hot WaterNuTech if required can advise on the first third by order of recommendations for the building fabric and building practice.For the second third, once a Low Carbon House is airtight it is essential that adequate ventilation rates are delivered to maintain a healthy living environment in the house. Before now, this was done by way of trickle vents. However this practice allows heat energy to leak from the house in an uncontrolled fashion, demeaning the efforts that have been put in to airtightening and insulating the house. The NuTech IRES System uses a heat recovery ventilation system, which recovers heat from the outgoing extracted stale air, and transfers this heat to the incoming fresh air; thus reducing the level of heat loss that normally occurs through uncontrolled ventilation. NuTech's HRV systems are further discussedThe solar hot water system tackles the last third. NuTech size and design the evacuated tube solar system so that it can generate up to 70% of a household's annual hot water demand. And by integrating the solar array to the heat recovery ventilation system NuTech can double the amount of solar energy captured and use it to reduce the overall energy demand. This reduces the amount of effort and input required by the main boiler, thus reducing the heating demand.
The IRES (Intelligent Renewable Energy System), which has been in-house designed by NuTech Renewables Ltd, allows the control of a property's solar and ventilation system through one single controller. This ensures the heating and ventilation systems that are integrated in the house work in harmony rather than having disparate controls
Why choose NuTech's NuTech IRES System ?
The benefits of the NuTech IRES System are as follows;
Solar System Benefits
- Free Energy
70% of annual hot water requirement met
Evacuated tube collectors have better winter performance and quicker response time than flat panels.
Heat recovery Ventilation System Benefits
- Recovers 80-90% of heat energy in house, which is normally lost through natural ventilation. This energy is re-distributed back into the property with fresh air. This reduces the amount of effort needed from the boiler, and therefore saves money.
Ensures proper ventilation rates in airtight build
Ensures the integrity of the high insulation levels and airtightness membrane are upheld
Low running costs
Low noise levels
The three units we supply have varying advantages, which NuTech can discuss with you.
Benefits that you can only get with the NuTech IRES System
Integration of the Solar and Heat Recovery Ventilation Systems Benefits – Solar Ventilation
Provides free solar energy to space heating
Maximises benefit of solar energy gain
Integration of Heat Recovery Ventilation System and Main Boiler Benefits – Tempered Air Heating
Provides some of the space heating through the ventilation system; thus reducing the amount of UF or radiators required saving on initial capital costs.
Tempers the air to reduce the possibility of a draught effect in winter
The benefits of the NuTech IRES System greatly improve when the connection to the boiler is to a renewable source, such as an Air to Water Heat Pumpor Wood Pellet Stove, instead of an oil / gas boiler.
The atypical house that NuTech installs these systems in, are for one-off self builder homes that are designed to be a Low Carbon Home. In most instances we are able to provide the house with a solar hot water system, a heat recovery ventilation system, solar assisted air heating to the first floor or bedroom areas, and tempered air heating to the ground floor or living areas (kitchen / living room etc) within the property. The level of contribution towards the space heating through the ventilation will all depend on the heating energy demand within each room and the property, as well as the airtight ness of the building.
