Pretty vague, but i'll give it a shot. i assume that your upper and lower floors are heated by the same unit. of course if your not sure you better check to see if there is a second t stat for up stairs in case there is a second unit that heats it. there may also be a zoning system that seals off upstairs ducts unless the zone stat for that area is calling for heat. so look for a second stat upstairs if you think it may be zoned. now to you original question. lets assume the unit is not zoned and only one unit heats both. then you may have a mechanical damper in the ductwork ,usually located close to the indoor blower that shifts to force more air upstairs in summer and more air downstairs in winter, these can usually be shifted as needed to control air to upper lower and are usually marked upstairs dornstairs etc. if you have no dampers etc, then you have reason to suspect the ductwork has come apart or been crushed before it gets upstairs. you'll have to go up or under the house etc and try to find duct problems.good luck

Why can't I get air flow into rooms?

The problem may be at the plenum. If the ductwork is connected at the very top of the plenum it can't build up STATIC PRESSURE. If the plenum was on the floor in front of you, you would measure down 12-18", from top to bottom, and that's is where the ductwork should start on the plenum. It may be hard to understand but we are not supposed to connect any ductwork on the HEAD of the plenum, as well as 12-18" from the top. If your blower is forcing air pressure from the bottom, into the plenum, and we release that pressure by cutting openings in the top, the pressure does not build inside the plenum. but with the ductwork away from the top of the plenum, air is forced in from the bottom and pressure builds at the top allowing a higher STATIC PRESSURE inside the plenum. And that pressure is released into the ductwork at a higher velocity and more evenly per duct. Most installers don't know about static pressure and will attatch ducts at the top of the plenums box. The blower then has a lower pressure and, although you feel some air in the problem room, its not enough volume to condition the whole area. That's a tough fix by the way but if that's your issue, have it replaced and if done properly you will notice a difference. An 8" flex duct is around 220-240 cfm. Depending on your size of room it may be a large enough duct. Normal size bedroom(not master) is about a 7" with non-foam insulation. An 8" is common for a kitchen due to the heat load so your 8" to that room should be blowing good. You may also try to increase the blower speed, make sure your evaporator coil is clean, and at the plenum there should be dampers that you can control the air flow per duct. I've seen that %75 of the time, with poor air flow its the placement of the dunt at plenum. Hope this helps!

Make : Weil-McLain Model : CG-5-SPDN Series 12 I have the above mentioned boiler which is located on the 1st level of a three story one family house, the area where the boiler is located is insulated.

You don't have an optimum distribution of steam in your house. Try closing a little bit the valves supplying the heaters in the lower floors. Close a little bit more until you get the desired balance.

I bougth an Uberhaus Airconditioner R410A. It is draining out onto the carpet, while I use the airconditioner, We hadn't attached the drainage tube! Is this supposed to be constantly drainned or does...

If this is the 3-in-1 air conditioner, then you have two options:
1- do you see two drain outlets on the back? one is at the very bottom and has a removable plug and the second should be about half way down also with a removable plug. This air conditioner has a small non-removable tank that will fill up and a red light on the panel will light up and the machine will switch to FAN mode when full. Then you have to roll the machine to a drain and unplug the bottom plug to let it drain out. Not resonable.Probably good for a basement with a drain in the floor, but not on the main floor or 2nd storey floor.

2nd method is to unplug the top drain (Keep the bottom drain plugged) , attach the plastic hose that the machine came with to this drain, find a bucket that is at the same height or below the top drain and let the water drain into the bucket. Then when it gets about 3/4 of the way full, empty the bucket.This way the airconditioner mode and the humidifier mode will work continously.
This is the way this type of air conditioner is made.

Hope that helps

There is water in the living room floor after the unit runs even for a short time. Where do you locate the stopped up drain. Where would I begin my search?

If your furnace is in the closet or laundry room, the coil that's leaking is either(1) on the top of the furnace if your ductwork is in the ceiling,(2) on the bottom of the furnace if your ductwork is in the floor. The drain that may be stopped up stubs out of the bottom left or right hand corner of the coil box. Sometimes you can flush it out with water but the best way is to find the end of the drain and get a shop vac and stick the shop vac hose on the drain, seal it real good and try pulling the junk out of your drain. Your drain may drain outside somewhere on maybe to a floor drain.

The plumbers have installed radiators with the hot pipe on the top right side of the radiator and the return pipe at the bottom right side of the same radiator does this sound correct?

Not normal but should work fine.Since heat rises this will allow the radiator to heat up a little quicker than if introducing the heat at the bottom. If the system ran long enough it would not effect the outcome of heating your home.

Hi there, I have two Fujitsu DC Inverter split units to heat my flat (england). The temperatures have dropped significantly -2 and below. This causes the outlet pipes to freeze up and when the units...

Normal cool temp 23 to 25 and heat mode 29 to 31. And regrading defrosting your pipelines no need any tray. You can insulate with Armaflex tube which is mostly used for best insulation. Hope there won't be further water leak.

I have a wood burning fireplace and i am trying to find out how to work the side and top damper and vent to heat my home

top damper wide open and bottom damper wide open will burn very hot but too fast if you close the top vent off it will smoke in the house the idea is not to smoke the house but once you have a good fire lit with hot cinders to cut back on the top to ceep some heat in cut back on the bottom to burn slower if this is a metal box wood burner it should heat great if it is a standard fireplace with a glass door you need to be careful how close the flame is to the glass it can break. glass front fireplaces don't heat as well as an insert wood burner let me know if this is uesful or any more assistance needed thank you
