So, most electrical heaters are extremely close to 100% efficient in terms of converting electrical power into heat. But is this true of fan heaters as well? In other words, how much energy goes into operating the fan as compared to the heating of the elements? [more inside]
We own a house. It's a kind of large, built-in-the-50s, added-on-to-in-the-80s, sprawly ranch-style house, but with 2 bedrooms, with vaulted ceilings, on the second floor. (Our kids' rooms.) In the summertime, they get hot, because of a.) vaulted ceilings - I've blown in insulation where I could, but there's still only 4 inches between them and the roof; b.) open stairway to downstairs - keeping the doors to the rooms closed helps a little, but kids don't really "get" that; and c.) crappy ductwork - the furnace is new, but the ducts are old, and it's a long, bendy run from the basement to the kids' rooms. I'm toying with some options for trying to improve the comfort level in our house - you are not my HVAC specialist (and I'm not opposed to talking to one), but am trying to see if my logic is sound.

It has come to pass that the best place for our 1 year old kid to sleep is in a crib in the walk-in closet in our bedroom. Now that the cold weather is upon us, I am looking for ideas for keeping him warm overnight. We have radiator heat throughout our drafty old house, and our bedroom tends to be one of the more poorly warmed rooms. The closet has no radiator in (or near!) it, and is therefore much colder still. To complicate this issue further, we STRONGLY prefer to keep the door to the closet nearly closed while we are in the room. Baby goes to bed around 6pm, grownups are on the scene from about 10pm onwards, and everyone is awake by 7am. He already wears layered pajamas and a sleep sack. Does anyone have any suggestions? My instinct was to find a tiny space heater that we could put in the closet, but a quick google tells me that I will kill all of my loved ones and everyone we have ever met if I do that.
While most things are going very well, my pregnant wife's back has really been hurting and her main relief has been an electric heating pad. However the heating pad is only 12in x 24in. I am hunting for a bigger heating pad if possible. Any help appreciated.
I live in a 1911 Craftsman in Seattle. The heating situation is... pretty weird. (See the "more inside".) My 42-year-old oil furnace still works like a champ, but the oil company folks say they won't service it any more and it has to be replaced. I have been searching and searching to try to figure out the best way to deal with this before it gets cold out, but I am not finding what I need. Should I change my heating method and can people recommend whom I might call for this? [more inside]
We have this furnace. In the summer it would be nice if we could run only the fan (We don't have central air), but according to the manual, Fan Only Mode requires the R and G thermostat contacts be wired. As you can see, only the RC/RH and W contacts are wired. Would simply swapping the orange wire from RC/RH to RH/G create the circuit needed for sweet, sweet fan action, or will it be necessary to run a new wire from G to the control board in the furnace, therefore requiring professional help?

I live in the SF Bay area and I'm thinking about moving to colder climates at some point, but for various reasons I can't handle a cold ambient temperature inside my home, even if I bundle up. In colder areas (specifically New England and the Midwest), how easy/possible is it to find apartments that are well-heated (perhaps buildings with a whole-building radiator system?) or other situations where I can have a warm (68-70 degree) home without paying through the nose for utilities?

I live in a drafty old farmhouse. My roommates and I are currently waging a thermostat war--one says it's cheaper to to have the heat for the whole house at 70 than it is for him to heat his room with a space heater. I maintain that its probably way more expensive to heat the entire drafty house. Who's right? We have electric heat. [more inside]
We've just moved into a new place and it's now gotten cold enough to turn on the heat. Two of the radiators are really loud with air escaping, and often have visible steam coming out of the valve on the side. I've never seen radiators do this. Is this normal? Is this safe?
We live in a house with central heating. There are floor vents all around the place. It sounds awesome, but we haven't been willing to turn the heat on just yet because one of the vents is right under one of my record shelves. How can we have a hot room but not melt my hot tunes? [more inside]

I live in rented accommodation in the UK. The hot water is scaldingly hot. The radiators burn to touch. The shower temperature is hugely unreliable -- scalding or freezing. The landlord is worried that a plumber will rip him off, based on bad experiences in the past, and unwilling to pay to investigate. Can you help me understand what's going on? I'd like to put my landlord's mind at rest regarding plumbers, and set his expectations regarding likely diagnoses and solutions -- and hence cost. I also suspect this situation is wasting energy and hence driving up the cost of heating bills. I'd like to persuade the landlord that fixing it might be a good idea. [more inside]

Our home in Seattle contains a dozen or so electric heaters. We would like to get rid of these and upgrade to something more efficient/attractive/economical. It seems our two options are 1) Central gas heating or 2) ductless heat pump. To make gas heating work, we would have to install ducts. Does anyone have any experience with adding ducts to a ductless house? One possibility that has been suggested is to put the ducts on the outside of one side of the house. This would probably work in our case since all of the large rooms in our house share a common wall. What are your thoughts/experiences with installing either gas heating with new ducts or ductless heat pump heating? I'm assuming that central gas would work just fine in a Seattle winter but I'm not sure if a ductless heat pump system would be adequate in the winter ( considering that our hope is to replace - not just augment - the existing system ).

UKTenantFilter: My heating broke on friday at 2pm. The landlord turned up at 4 but didn't fix it then because he 'wanted daylight to work on it'.

Just replaced a 50-year-old tar/gravel roof with white shingles. This is in Florida. But now the house is hothothot, heat keeps rising, air-conditioner runs constantly but can't keep up! It's just after noon and 84 degrees in here! The roof is low-hip, the attic is a crawl space insulated to about R-30, there's a turbine on the roof and three passive vents. Still hot! Depressing after writing such a big check. Capable roofer says previous thick layer of tar/gravel probably insulated a lot. But now what's my next step? 1. Would a white latex coating be more cost-effective than a solar-powered vent? 2. Any other suggestions? Whew, and thanks!
I have air conditioning vents in the floor at the side of the room. The vents can be angled in different directions. If I put a large dresser against the wall, above a vent, with clearance of a few inches, will it be substantially detrimental to heating/cooling?
