In 1999 Repsol bought 97.81% of the Argentine oil and gas company YPF S.A., which at the time was the largest oil-and-gas company in Latin America.

Le 6 June 2012 By Melissa Dupuis. HSPF is an acronym that stands for âHeating Seasonal Performance Factorâ. HSPF is a rating like SEER but instead of being a rating used to measure the efficiency of a cooling system, it is a rating to measure specifically the heating efficiency of a heat pump.A heat pump has both a SEER and an HSPF rating since it can both cool and heat a building. In 2012, the highest HSPF rating on a heat pump is approximately 13. 2  If you refer to the chart below, you can save approximately $200 if you own a 9 HSPF heat pump versus owning a 7 HSPF heat pump. 3  Note that it is with a 3 ton heat pump with an average electricity rate of $0.086 (Quebec base rate is approx $0.0751).
