- code_biologist 4y agoAm I crazy, or are those two sentences completely contradictory?
- krageon 4y agoI thought it was a joke. If you don't have ducts, you are by definition ductless. So that's how you must go.
- Dylan16807 4y ago> So that's how you must go. No, you can go to ducts by installing them. I believe the comment is advising against doing so.
- aclatuts 4y agoI think he means having a duct work for the whole house for a central heat pump is good. But having a heat pump per zone is also good if you don't have ducts for the whole house. Some newer home designs separate heating and cooling from the air exchange systems so there are multiple zones of heating and cooling.
- aftbit 4y agoI read it as: Ducts are better but not so much that it's worth tearing everything apart to install them. If you don't already have ducts, you should definitely use a ductless system. If you do have them, you get some other benefits.
- notyourwork 4y agoDucts are great with a heat pump and an air handler with variable fan speed.
- fifteenforty 4y agoI paid real money to have my ducts removed. They cause issues installing comprehensive insulation and caused hot/cold spots on the ceiling.
- metadat 4y agoHonest question: Why would one care about cold or hot spots on the ceiling? I don't spend much time up there.
- 0_____0 4y agoIt’s still a thermal path between inside and outside, and thus wastes energy if you’re trying to maintain an internal temperature that is different from the external temperature. Also there are radiative effects - hot spots on ceiling will radiate IR into your space. Just try standing under a corrugated steel roof in the summer.
- fifteenforty 4y agoApproximately 70% of the heat loss from your body is as radiated heat. Ceiling insulation is critical for thermal comfort. Have a look at the Efficiency Matrix YouTube channel videos on insulation consistency.
- Dylan16807 4y agoThe average temperature sure. But would uneven spots have that much effect on the thermal radiation I get sitting over a meter away?
- EricE 4y agoLess that 2% of insulation being out of place can waste something like 40% or some ridiculous amount of energy. It's quite nuts how even just a little break in insulation can have a significantly negative effect. A few years after I moved into my first home - a townhouse - I added some R-16 bats to the already existing R-12 insulation in the attic and it more than cut my heating bill in half. It was a three story narrow, townhouse - not that much square footage of ceiling compared to the walls/rest of the house but it made ALL the difference. If I didn't live it, I wouldn't have believed it. And I kind of did it on a whim since I didn't need that many and Lowes was having a sale on insulation. I would have done it the first week I moved in and had a couple far more comfortable winters!
