enter image description hereI have a room in the basement with equipment (computers) that gets really hot. There is an ac vent but the thermostat is nowhere near the room.

Also in an alcove is the hot water heater behind a louvered door.

I want to install an extractor fan essentially and create negative pressure in that alcove which will suck in the hot air and expel it outside through the existing hot water heater exhaust ducting. Putting a direct extractor outside I figured it would create back pressure and back draft, so how would I best connect an extraction system into the same ducting as the hot water heater. It vents directly outside the wall a little bit higher up in the space

  • Liquid-cool the computers and dump it into the cold water supply to the water heater. You've already paid for THAT electricity, might as well get some more use from it. – Ecnerwal Jul 27 '19 at 19:52

    Not a good idea to mess with the balance of your hot water heater exhaust set up. – Alaska Man Jul 27 '19 at 20:59

    This is an extremely bad idea....perhaps rebalancing the A/C ducts in the basement is a better bet? – ThreePhaseEel Jul 27 '19 at 22:01
  • Almost certainly would be a code violation to employ the water heater vent for this purpose. – Jim Stewart Jul 27 '19 at 22:47

    messing up the ventilation for a gas fueled heater is the kind of mistake you only make once. an opportunity best avoided. – Jasen Jul 28 '19 at 8:49
