Home Improvement Stack Exchange is a question and answer site for contractors and serious DIYers. Okay I actually do understand the purpose of the bathroom fan; it gets the steam out of the bathroom after a super hot shower, right? One other thing to think about - even if the fan isn't running, hot air rises and most of it is going to end up in your attic. Is not advisable,your hearth and environment must be watched,create a window on your bathroom wall to be free from fan brake down and odors in your bathroom.
Building code changes will happen, if not all ready changed, that homes will have to have a certain air exchange per hour. Sign up for our newsletter and get our top new questions delivered to your inbox (see an example). If your bathroom doesn't have a window and no fan then that all that moist air is going to create a perfect environment for mold and other unpleasant things.
Also, excessive humidity will probably make it's way into your walls and I you have a wooden house then it will start to rot. While I understand not wanting to have a vent on your roof, I would recommend either getting a low unobtrusive roof vent on the back slope of the roof or possible putting a vent out the eave or wall. If you vent out the eave and have soffit vents pulling air into the attic (for ventilation), you'll end up sucking the moist air up into the attic anyway. See this related thread for other comments: How do I refinish a bathroom ceiling after it got moldy and peeled? As I found out much to my chagrin way back when I had to open up the wall on a bathroom that had a long failed power vent (black mold). Other tales from the Pacific Northwest brought to you by incessant damp in bathrooms, "The Amazing Descending Throne", an oft told tale by one of my Dad's friends who had it happen while he was sitting on it. Though a contractor somewhere needs a bit of karmic revenge as it's a crime against physics and materials to vent moist air into an attic space.

Absolutely, if properly wired, you can take a single loop of hot water baseboard heat and subdivide it, giving each sub-loop its own thermostat and zone control valve. Properly wired, the individual thermostat calls for heat, the zone valve opens, when the valve is fully open an end switch in the valve connects a second pair of wires that turn on the circulator pump back at the boiler.
Photo at left (reader contributed) illustrates typical wiring connection at two zone valves. When I got into that trouble years ago I was wiring up a Honeywell zone valve to a system already using Flair zone valves. My ugly rough sketch above needs to be re-drawn neatly, but there I show how we successfully wired-up a mixed brand zone valve installation. Watch out: The Honeywell zone valves are NOT compatible with Flair and White Rogers unless you follow careful wiring details.
I give an example above, but you may need to review wiring with the manufacturers of your zone valves. Zone-A-Trol Valves should not be wired in the same circuit with zone valves of a different make or manufacturer without first consulting your local Zone-A-Trol representative or our factory engineering department for special wiring information.
The thermostat wires on the master (primary) control will show about 20-volts from the on-board thermostat relay transformer inside the primary control.
No voltage should be presented by the zone valves, thermostat, or transformer circuit TO the primary Controller. We see 24-volts through the zone controllers and transformer but Zero voltage on the zone valve end switch wires that go to the thermostat TT terminals on the master or primary control. WATCH OUT: to avoid overloading the tt or its power or circuit, check the zone valve wiring instructions. From Flair Manufacturing's original installation instructions for the Flair Zone-A-Trol we include these wiring details. On installations where it is not convenient to wire from valve to valve as in the diagram, a separate 3-color wire conductor can be run from terminals 1, 2, 3 of each zone valve to a convenient junction point. By observing and respecting the color codes, conductors from corresponding-numberd terminals of each zone valve may be joined or spliced together and a single conductor may be conducted from that splice to the appropriate power and control terminals shown in the wiring diagram.
Watch out: when connecting wires to terminals at the zone valve and at the thermostat or any other control, do not let the stripped end of the wire touch or short out against any other wire or terminal. See this image for Complete and detailed wiring diagrams for FLAIR 2-WIRE ZONE-A-TROL VALVES.

At left the thermostat wiring diagram illustrates use of a Flair APOV2 wall thermostat in a typical 2-wire application controlling a heating appliance. In this application the thermostat is acting as an spst (single pole single throw) switch to turn heat on or off, often by operating a zone valve.
When used to operate a zone valve the thermostat wires are connected to the zone valve terminals, not to a primary control on the heating boiler.
At left the thermostat wiring diagram illustrates typical use of a Flair APOV2 wall thermostat in a 3-wire application controlling a heating appliance.
In this application the thermostat is acting as a single pole double throw (spdt) switch to control heating & cooling or in some zone valve applications. I am adding a third zone (basement) to my oil fired hot water baseboard heating and have it all planned as far as the plumbing is concerned.
The add-on heating zone will have it's own 24V zone valve so will require a wall mounted thermostat. I guess my question is, can I just connect my new valve and thermostat directly to the aquastat terminals that "appear" to power the other valves and thermostats ? If so, is there anything I need to be aware of, like possibly wiring it backwards and frying something ?
If I can just add the new "loop" directly to the aquastat, in what order are the connections made ? If you need me to provide more detail on the types of thermostat, aquastat and zone valve I am using I can. When the TT calls for heat (yes 2 wire is fine) it tells the zone valve for its zone to OPEN. So you'll find a pair of wires from TT to the zone valve and a pair of wires from the zone valve to the circulator relay. Watch out though: the wiring connections can vary a bit among zone valve brands - if all of yours are the same brand you can look at the existing valve, follow the wires, and you'll see how the zone valve is hooked up. The other circuit is simply connecting the other two wires on the zone valve to the connections on the circulator relay.
For the second circuit to the relay, I'm assuming the relay is attached to the circulator pump itself.

You will not only get mold as others have mentioned, but the moisture will reduce the effectiveness of the insulation in your attic. I had grown up in a house with a bathroom fan, and thought perhaps it wasn't necessary to vent the moisture, after all, since it didn't make sense to me to open the window in the winter.
After a year or two, the ceiling texture started cracking and falling off, and around the same time I noticed black spots developing on the ceiling, as well. We include wiring diagrams for most zone valve models and we describe special wiring problems that can occur if you mix different types, brands, or models of heating zone valves on the same hydronic heating (hot water heating) system. Where you can run into trouble is with an installation that has a mix of different brands of zone valves. I called my heating supplier who had Dave Ferris (now retired) on deck to answer wiring questions.

Without Dave the next-best is to lookA  with care at the instructions that came with the zone valves, and at the wiring diagrams for hook-up instructions; if you are left still confused, the manufacturer will know how to hook-up. But as the thermostat is basically an on-off switch, indeed we've discussed with readers the successful combining of more than one zone valve switched by the same thermostat.
For switching multiple zone valves with one thermostat you may need to have the thermostat control a switching relay that in turn switches the gang of multiple zones.
We were taught to completely remove the zone valve motor and electrical parts while sweating the zone valve to the heating system piping, but even so, overheating can damage the zone valve moving parts or o-ring seals. The Flair Zone-A-Trol valves in the company's wiring diagrams are typically shown wired in parallel.
Example, aquastat to one connection at valve, 2nd connection at valve to one connection at thermostat, other connection at thermostat back to aquastat ?
If there are different brands you'll need to ask for a clue from your HVAC supplier or the manufacturer.
I have the box on the front of my furnace which contains controls for how hot the water gets and when it needs to be heated.

I am replacing a ceiling fan that is controlled by 2 wall switches (1 for fan and 1 for light).
Since you will be using a remote and not the switches, you should be able to use either the red or black and whichever switch will power the remote component and nut the other wire off and just use the remote and neither switch for control. I have been licensed by the State of North Carolina for ten years and am currently the Building Maintenance Superintendent for a municipality.
Packaging should be the same as what is found in a retail store, unless the item is handmade or was packaged by the manufacturer in non-retail packaging, such as an unprinted box or plastic bag. Import charges previously quoted are subject to change if you increase you maximum bid amount.
Apparently the purpose of venting moist air is to prevent mold from growing and to prevent the moisture from damaging your ceiling, walls, and cabinets. Honeywell warns not to use silver solder when sweating zone valves because of the higher temperatures required with silver solder. My other two zones have their own valves and thermostats and the wiring at the valves is all connected with wire nuts and doesn't make any sense to me. The instructions seem to indicate that I only use the yellow wires and the red wires were for auxiliary, whatever that is. One 24v circuit runs in series as follows - transformer, zone valve, thermostat, transformer.
The replacement fan does not have a remote control but I have a universal remote That I will be wiring into the fan. I have extensive control wiring experience.OrganizationsRefrigeration Service Engineers Society.
