I have an existing gas furnace system and a separate gas hot water heater. I'd like to get rid of the hot water heater because it is taking up too much room, and I want to use that space to fit in a washer and dryer. I have another house where the furnace and the hot water heater are all the same unit without a tank. Can someone modify my existing furnace to attach a tankless hot water unit to my existing furnace, or do I have to buy a whole new furnace to have one that integrates it?
We have an issue with the hot water supply from a 2004 Peerless oil furnace/boiler with tankless hot water. The shower starts at full temp, but quickly goes tepid (too cool for a comfortable bath/shower, but not ice-cold) and returns to full heat after 5-10 minutes. This is most apparent during the first two showers of the day or bath in the evening - subsequent showers or baths don't seem to have the problem to the same extent. This makes troubleshooting difficult, as we can't tell until an hour or so after running all that hot water to see if the problem returns. It's most pronounced in winter, during the summer the issue seems to go away. (Details inside) [more inside]
What am I not understanding about my HVAC system? [more inside]
I've read so much conflicting information and opinions regarding this, I have no idea what to believe. Logic tells me that keeping the temperature high when we're home and awake, then dropping it when we're asleep or gone is the most efficient use of energy. But others have told me that the amount of work a furnace needs to go to bring a house (1450 sq ft for us) up a significant number of degrees daily is less efficient than simply maintaining a constant temperature. That doesn't make sense to me, but I've heard it from people whose opinion I respect. Help! [more inside]
I bought a house in August this year (2.5 months ago). Just tried turning on the heat for the first time and it does not work! I had a repair company out and was told it was in terrible shape (and super old). They would even have to special order the parts. [more inside]
We have a Ruud Achiever 90 Plus with variable speed motor. It works great heating up the house, but when it's trying to maintain the temperature (say it's set for 65 and it's currently 65), it constantly clicks. The sound is very annoying. Does anyone know what would cause this? [more inside]

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?

We had our furnace inspected yesterday. It's worked fine all winter. We were told we have a bad heat exchanger. We were encouraged to buy a whole, new furnace for $10K. Our preference is to ride it out with the old furnace for another few years and replace it when it is convenient for us. Does that make sense? [more inside]
My "Williams 30,000 BTU Natural Gas Direct-Vent Wall Furnace" is an eyesore and I'd love to build my own custom cover for it, but is that safe? Can I only use metal or can I use wood? I'd have a friend build it since I don't know much about it, but I'm wondering what I can do to hide or replace it. BTW I rent my apartment, so any changes I make should technically be reversible. Link for reference.

I was away from the house last night when I got a text from my wife about a strange "fertilizer" smell coming from the basement of our house. I came home a few hours later and smelled it immediately - hard to describe, but a slightly acrid, recognizable chlorine-y scent reminiscent of a garden center. It was noticeable on the first floor but stronger in the basement. I sniffed around for a while but couldn't locate an obvious source. The only thing I could find that was awry was that the pilot light had gone out in the water heater (only time that's happened), which is suggestive of a chimney backdraft. I relit the pilot without issue and verified that the water heater was venting correctly with a stick of Nag Champa. Multiple C02 detectors in the house detected nothing. We'll have an HVAC guy come out ASAP, but I'm wondering if anyone else has experienced this and whether I'm diagnosing the issue correctly. Is this what water heater fumes smell like? We've lived in the house for a year, and this is the first time it's happened. [more inside]

I have found that space heater with plastic anywhere on it starts to smell like burning plastic if you run it alot. I have also found that the thermostats on a lot of space heaters do not work well. example you set it to 73 but it just runs and never turns off or turns off before reaching 73.
Are there improvements that can be done to them to improve their efficiency and safety? Are there retrofits? Would I be able to purchase something more modern that would directly replace the existing units? [more inside]
Whenever I change my furnace filter (approx every 60-90 days), it's always bent inwards towards the furnace fan. It's gotten significantly worse this year, and tonight when I tried to replace it, the filter was nearly sucked into the furnace. What causes this? Do I need to call for service? [more inside]

Last night around 5 in the morning, we woke up because it smelled like natural gas--hard. After determining it wasn't coming from the oven, I remembered groggily to check the maintenance closet in our hallway, which contains two water heaters--one for our apartment, one for the apartment next door--and the natural gas furnace that heats our apartment through vents. I think something is happening to our furnace that causes it to do this, but I don't know what; I managed to stop it, but I'm not sure how. [more inside]
On the book of Daniel chapter 3 -- when his friends were to be burnt on the fiery furnace -- Nabuchadnezzar commanded to have the furnace heated seven times hotter.

It's fall and I should have my furnace serviced. It's a 1991 furnace that has kept chugging along just fine so far (touch wood) but that I hope to be replacing in 2013, so I don't want to pay for more than a basic servicing/cleaning job now. I live in Toronto. Does anyone have recommendations as to whom I should hire for the job?
