Gas heating compared to heating by PAC air / air




by Titjus » 10/05/08, 20:11

Hello,

I have a natural gas heating system.
I want to install two air / air heat pumps to save energy.

gas -> electrical energy (efficiency 55%) -> heating by heat pump (efficiency 300%) OVERALL PERFORMANCE: 165%

gas -> direct heating YIELD: 80%


I would save 1 m3 gas on 2!


Economic comparison? ...


Thank you
