During a renovation I decided to change my gas forced air heating units to high efficiency units to allow me to remove the old brick chimney (giving me more living space) as they use plastic exhaust pipes.
I have a gas hot water heater that I need to change as it was exhausted via the brick chimney.
Can someone recommend a few gas hot water heaters that are high efficiency and don’t need the chimney? Please explain the exhaust method? I’ve read about “Power Vented”. Is that what I need? Are there other gas hot water heaters (aside from tankless – won’t get ROE for 10 years or so).
I did think about electric but don’t feel they are cost effective in my area due to the cost of electric.
