ERV/HRV Summary
When to Use a TR or HR*
ERVs
• Transfer BOTH heat AND humidity
• Use enthalpic core
• S&P’s TR and TRC are ERVs
Energy Recovery Ventilators (ERV) and Heat Recovery Ventilators (HRV) both
moderate extremes in ventilation air temperature so what is the difference?
HRVs
• Transfer ONLY heat
• Use aluminum core or simple plastic cores
Can ERVs be used in climates subject to cold winters?
Yes! Because ERVs transfer both heat and humidity they are the perfect choice for
any climate. In the winter ERVs:
• Warm outdoor air close to room temperature
• Use heat that would otherwise be lost with the exhaust air.
• Transfer water vapor to moderate extremes in humidity levels
• Help prevent moisture damage or over-drying of the home.
Why are ERVs better than HRVs?
HRVs and ERVs are similar in that they both:
• Improve Indoor Air Quality
• Moderate extremes in ventilation temperature
• Use heat that would otherwise be lost with the exhaust air in the winter
• Provide necessary fresh air while pre-cooling in the summer
Why are S&P’s TR and TRC the Ultimate ERVs?
ONLY ERVs have the ability to transfer water vapors or moisture so they:
• Help prevent over-drying of the home in colder seasons
• Lessen the demand on the air-conditioning system in warmer seasons
• Are typically 3x more energy efcient in the summer than products (or units) that
transfer only heat (HRVs)

S&P’s TR and TRCs provide the same benets as other ERVs on the market.
Major advantages include:
• More heat transfer than most HRVs
• More humidity control than other plate exchangers
• Simplicity and positive airstream separation not offered by wheel type ERVs
• 10-year core warranty
