Electric furnaces can reach this high: They all have efficiency ratings between 95% and 100%. Furnaces that burn oil, gas, or propane must vent exhaust to prevent toxic gasses such as carbon ...

That's because fully electric furnaces do not lose any heat through venting gas, so they are all considered high-efficiency.

Compatibility with PVC venting ... propane tankless water heater might deliver anything from 25,000 to 200,000 BTUs of heat, which many consider sufficient for a 3-bathroom home. A high-efficiency ...
