    Centralised systems consist primarily of a single unit that can be configured in order to ventilate all rooms via ducting located typically in the roofspace. These systems can be used to move large volumes in new buildings or in older buildings that have enough space for a unit. Heat recovery ventilation works independently of your normal heating system.

    Then, homeowners started to ask whether those changes were really worthwhile. A heat recovery unit allows the internal air renewal of the premise, maintaining and recovering the energy used for air conditioning. A good MVHR system will have excellent insulation. The ductwork and unit should be airtight.

    Stiebel Eltron is used at DP Heating and Cooling for all heat recovery ventilation systems. Stiebel Eltron systems can return up to 94% energy lost through windows to your heating system. Their LWZ 180/LWZ280 heat recovery units can capture up to 94% heat and reduce condensation in your home. This will help you stop mould growth.

    Heat is transferred by an evaporator or condenser inside a wicked, sealed tube containing a fluid that undergoes constant phase changes to transfer heat. The fluid within pipes changes from a fluid, to a solid in the evaporator sections, absorbing the thermal energies from the warm-airstream. The gas condenses back to a fluid in the condenser section where the thermal energy is dissipated into the cooler airstream raising the temperature.

    Common sources include gas ranges and unvented space heaters as well as gas ranges and water heating appliances. Even breathing can contribute to the problem if carbon dioxide reaches an excessive level, creating stale atmosphere. At 100% capacity, cold water passes through the double wall heat exchangingr and is fed to the top water tank. MVHR also extracts and mini rekuperatorius butui recycles heat from the outgoing air using a central heat exchanger. The heat that is recovered is then fed back into the supply. This helps to optimize the building’s climate. However, it is important to note that MVHR itself does not provide heat. No matter how hard you try, it’s not easy to set up this ventilation system with all its piping, ductwork, and heat pumps.
