Invisible Mistakes that Cost Dearly
Even the most expensive heat recovery unit will perform poorly if you cut corners on installation materials. The most common issues are leaky duct joints and poor insulation, leading to heat loss before air even reaches your rooms.
The consequences aren't immediate, but they are significant. A leaky system means higher noise levels, increased heating bills, and potential moisture buildup in structures, which eventually leads to mold and damaged finishes.
A Transformation of Silence and Efficiency
By using high-quality fasteners and insulation, you create a sustainable home ecosystem. Properly selected insulation materials absorb fan vibrations, ensuring you hear only quiet air movement at night, not metallic rattling.
System airtightness ensures maximum heat recovery efficiency. When every joint is sealed with professional tools, the recovery unit works easier, consumes less electricity, and lasts significantly longer.
Save up to 15% on energy costs – simply by ensuring maximum duct system airtightness and proper thermal insulation in transit zones.
