    Air quality. HEPA and UV light question

    I have never installed any of these air quality devices. I always assumed it was BS. I had a coworker talk about how he liked his UV light and since my son and I have seemed to have some allergy...

    I didnt think about that, that doesnt seem very clean.

    No pump. Just uses the domestic water pressure. Theres a valve inside the AHU which opens on a call for heat. Like your kitchen sink. It allows hot water to go through the coil.

    That makes sense, but if the water heater is burning gas to keep the water at temp in an insulated container it will be running less than if the the hot water is being routed through a coil with 70...
  10. Is a hot water coil more efficient than a gas furnace?

    Im not convinced using any replacement on the market is good for me. We use a lot of heat pumps in my area and any reduction in performance isnt acceptable. I recommend paying to have the leak...

    I would not think the high side would drop because of air flow. Just from what ive seen in my experience. The Delta T does seem a little high though.

    Are you saying these are all exactly the same, or basically the same with some differences that will effect quality and performance. Either way, thanks for all that info.

    Follow up:

    I talked to one old guy I worked with. He said "there all the same......except Payne, I wouldnt put in a Payne." it seems everybody thinks theyre all the same except for brand "X".
