Are you still paying high heating and cooling bills for your home and cant understand why?? Thinking you need to replace your HVAC system?? Let Harmony Heating and Air Conditioning Inc. professionals show you how HRVs can help your existing HVAC system work more efficiently.
Heat recovery ventilation (HRV), also known as mechanical ventilation heat recovery (MVHR), is an energy recovery ventilation system using equipment known as a heat recovery ventilator, heat exchanger, air exchanger, or air-to-air heat exchanger. HRV provides fresh air and improved climate control, while also saving energy by reducing heating (and cooling).
As your homes efficiency is improved with insulation and weather stripping, making your home intentionally more airtight will also make your home less ventilated. Since your home requires a source of fresh air, the need for HRVs has become a necessity more than an option. So why not just open a window? While opening a window does provide ventilation, your home’s heat and humidity will then be lost in the winter and gained in the summer. Both results are undesirable for the indoor climate and for energy efficiency since your home’s HVAC systems must compensate. HRV introduces fresh air to a building and improves climate control, while promoting efficient energy use.
HRVs can be stand-alone devices that operate independently, they can be built-in, or added to existing HVAC systems. For a small building in which nearly every room has an exterior wall, then the HRV/ERV device can be small and provide ventilation for a single room. A larger building would require either many small units, or a large central unit. The only requirements for the building are an air supply, either directly from an exterior wall or ducted to one, and an energy supply for air circulation, such as wind energy or electricity for fans and electronic control system. When used with ‘central’ HVAC systems, then the system would be of the ‘forced-air’ type.
HVAC systems might sound confusing, so let our professionals at Harmony Heating and Air Conditioning Inc. with over 27 years of experience take the guess work out of your energy saving needs.
