What system to replace forced air heating system? House always cold - forced air system ineffective. Replacing with gas boiler. Told need 14 radiators; 6-bedroom house with lots of daughers! One company recommends a combi-boiler; another that we need an unvented system; quotes range from £6 000 to 16 000. Very confused. Any advice gratefully received. I live in the UK where forced air systems have dropped out of fashion and no company I have spoken to wants to support. Don't know why situation in US so different. 3 bathrooms; 7 persons; showers all mixers.

Can I put the cold air supply of a forced air heating system in the basement instead of the main level? I'm redoing our wood floors and would like to eliminate the obtrusive large supply grate.

I HAVE A ONE ZONE FORCED HOT AIR HEATING SYSTEM i NEED TO HEAT SEPERATE ROOM HOW DO i ADD A ZONE? THE THERMOSTAT IS IN THE MIDDLE OF THE HOUSE THE ROOM NEEDING HEAT IS ON ONE END OF THE HOUSE THE NATURAL DRaft of the house is away from this one room. so if i heat this room it can possibly help heat the rest of the house because the air flow of the house is from this one room thru the rest of the house Can I keep the existing thermostat in the middle of the house and add duct work and a thermostat to this one room? do I need to install anything special?I have an older forced hot air system about 15 to 20 years old.Or should I just duct to this room and move the thermostat?

is it normal for cool air to come out of your vents in a gas/forced air heating system? i turn the heat on and it seems to warm the house up, but when the air first starts coming out, it's pretty cold. is that normal? should i call my landlord to fix that?

Ventless fireplace vs. forced air heating system? We live in a 5,000 square foot house in Chicago, 3 floors up and an English Basement. We had a ventless fireplace installed and run it about 14 hours straight in the winter and just keep our zoned heating (forced air) off. Is it cheaper/more efficient to use the ventless or am I spending MORE money running the ventless non-stop? Being that the ventless is 100% efficient, or close to it, it can easily heat the upper three floors comfortably. So, am I spending more using the ventless? I'm trying to save $$ with gas being so high these days. Thank you to everyone in advance.

Just bought a house with a forced air system? I have a central air-conditioner and a forced air heating system with vents all over the floors on the 1st floor and on the ceilings of the 2nd floor of the house (2 zones).

Any consideration to a size of it?

do forced-air heating systems use refrigerant? im trying to figure out the difference between a heat pump system and a forced air heating system. yeah, but my question is more specific to the way it heats the air. does a forced air system use refrigerant like a central system? because i have a heat pump system that has a compressor and condenser outside too. i am getting my home inspection license and i need to be able to distinguish the two.

How do I know if the fan control switch on my home forced hot air heating system is bad? The blower motor seems to turning slower than normal and I'm wondering if the control switch controls the amount of current to the motor. From what I can tell its a single speed unit and the controller is an old Honeywell switch with a 2 position button, in for constant on, and out for auto on. The blower motor belt is tight and the motor looks and sounds ok, just really quiet where before it was considerably louder.

Issues with a forced air heating system? We live in a rented, three story townhouse. The heating system was never particularly amazing, but it did a good enough job..it we set the thermastat, it would get to the temp we wanted. Two bedrooms upstairs did not get a whole lot of heat or AC, but again, we could work with that. The system was older and ended up dying..the landlords put in a whole new system and we've have nothing but problems ever since. Basically, the colder it is outside, the colder it stays inside. I have to set the thermostat to nearly 80 and the system runs constantly, but the temp on the main floor won't budge above 68-70. In one upstairs bedroom, the temp will usually hover closer to 60. We've have the company back out several times..first he replaced the thermostat..nothing. Then he said it is because the vents need to be cleaned..however all the research I have done on that state cleaning the vents is more for health reasons than anything else. I removed one duct cover and yes, it is pretty gross in there, but there is nothing blocking any of the vent openings. I am thinking the AC company talked our landlords into a unit that is too small or not powerful enough for our townhouse or they are simply not fixing the issue. I would appreciate any input from someone with experience or knowledge in the HVAC field. We are going to pay to have the vents thoroughly cleaned, but I would like a basic tutorial in how the systems work and what to expect once the vents are clean (generally speaking of course).

Why do some of the ducts in my forced hot air heating system "pop" and "bang"? How do I stop this "popping" and "banging" stop?

What do the overhead vents do in my forced hot air system? I have a forced hot air heating/cooling system in my house. Downstairs there are vents in the floor and you can feel the air coming through them. Upstairs there are ceiling vents, but we have never felt air coming through them (hot or cold). Consequently, besides our foyer, most of the rooms upstairs are A LOT colder than the rest of the house. Is there something we can do to fix this, or should we call a heating specialist to check it out?

We need to replace our boiler. What kind is best for our current heating system? We have a hot water forced air heating system (baseboard heat), and we have a couple of quotes from various specialists. It is a natural gas system. One told us that a high (95% AFUE) efficiency boiler will lose efficiency with our heating system. Another told us that any boiler will work. It sounds like he would swap out more stuff (i.e. pipes in the basement). We will get some more estimates, but it would be nice to get some unbiased answers about this.

Which is a better heating system for a new home - Forced Air, Hot Water Baseboard, or In-floor Radiant? Seem to me that Forced-Air is the worst for allergies. Hot water Baseboard is good but more expensive to install. And Radiant is the most expensive to install, and if there's a problem with it, you have to break open the foundation to fix it. Also we want to put real solid hardwood floors, and those are not compatible with In-Floor Radiant Heating. I am leaning toward either Forced-air or Hot Water Baseboard. Which is better?

Forced hot air heat....How to keep a constant temperature? I have a forced hot air heating system in my apartment. When I set the thermostat to 68, the temp in the room goes the whole way down to 62 before the heat comes on and then goes up to 74 before the heat turns off. This is freezing me and costing me a fortune!! Is this a problem with the thermostat (its an old mercury one) or is it the nature of the forced hot air system? I could buy a digital thermostat, would that help?? Please, only people who know what they are talking about!

Does your home heating unit (forced air oil heater) control/work with your central air conditioner? We're having some problems cooling our house. My husband says it's because we need a new heater unit (forced air oil heater) and it's not blowing the air. I say it's becuase we need to reposition ducts that were covered or disconnected when we redid the kitchen and the house is so hot because the sun beats in the sliding glass doors all afternoon and the only working vent comes out behind the stove and then the hot air goes all through the house and the remaining working vents (3) can't keep the house cool (it's a small house, but there should be 6-10 working vents). He says air should be blowing quite rapidly out the vents. I've never experienced a central air system where air came flying out the vents, it usually slowly flows out. I know we need to replace our heater by winter, but I think a set of blinds for the window and fixing the ducts and vents is the answer for now (and cheaper, too!). Can anyone give me an opinion from a heating/air conditioning professional standpoint?

Forced air/heat, air is fine, will heat to certain temp. then shut down.? I have a forced air/heating system, at first no air or heat, now air works but heat will only heat to 64 degrees then shuts down (even blower shuts down). If I wait a few minutes and let the temp cool down to 60 then turn it back on, it will heat to 64 then shut down again. Thermostat controller inside is ok with new batteries, thought it was thermostat controller so I changed it but same thing happens. Any suggestions? Unit was new in 2000. It is gas forced air/heat, now it only fires up sometimes then shuts down right away, wont stay on longer than 5 min. if at all, I hear it turn on but no air blowing from the vents, just hums. The air filter is clean and inside thermostat controller is new w/new batteries. Going to try replacing the sensor??

Forced Air vs. Gas Boiler Heating Costs? In a home in New York state (typical outside temp is 30F Nov-March, 80F Jul-Aug, and in the 60s the rest of the year, while indoor temp is maintained at 64F during the cool months with a nightime/workhour setback to 52F), which would be more efficient: a gas forced air system or a gas boiler system with iron radiators? Things to consider are the "unseen" electric costs of running the forced air fan, the costs of keeping the boiler going in the summer (can it be shut off?), the cost/ability of returning from a 52F setback to a 64F living temp, and common maintenance costs (i.e. does one break more than another?). I know boiler systems are more comfortable and don't burn the air, but this question is aimed soley at the monthly cost of operating one unit vs another. Both would be non-condensing units with efficiency ratings of 80%. Simply put, in a common setting, does one usually cost more to operate than another? Thank you! I have no interest in central air conditioning in the summer (there are typically no more than 2 weeks during the summer where it's that uncomfortable), so the lack of ducts is no problem.

How do you install central air in home with forced hot water by oil? I bought a Victorian home and it has a 5 year old forced air by oil heating system with baseboards. How can I add (or can I ) central air into the system? And if so how much would it cost? Thanks

I have electric forced air heat in my apartment and there is a sticker on it that says...? "clean a minimum of every six months. Turn off power at panel and remove grid."

Ok. I have heating and cooling system (Force Air). During winter, heater works great, BUT ...? in summer when turning AC on lights go off. Someone told me that I have low voltage wiring, but I had an electrician come over this friday and he said that my voltage wiring is pretty good. So I don't know what the real problem is. He said that I needed to check on the AC, that it might be somenthing wrong with it. I don't know, what's also funny that when lights go off, that MAIN cuircuit braker goes off instead of the actual cuircuit braker where the AC in conected too. Can someone help me or refer me to someone that is really good to check if posible both Electrical and Force Air person? You know sometimes there are people that can do both things? I am in Chicago, IL. Thanks :)

Has anyone used the Hydro-Sil heating units to heat a whole house? I was interested in the Hydro-Sil heating system (hydrosil.com) and was interested in knowing if anyone has used them and found the results to be good. The literature on the units state that they are cheaper than the forced air systems and heat much better. I really really appreciate any input. Thanks.

Do heat pumps replace a furnace? Currently, my house has a forced air heating system being run off a furnace that's in a 4-foot crawl space. The cooling is through in-wall AC units. I'm a little nervous about carbon monoxide spreading, both under the house through the open area crawl, or through the forced-air ducts. I'm looking into getting a heat pump. If I also get an electric tankless water heater for my hot water needs, will I still have a need for the furnace or can I remove or disable it? Also, I read the existing duct work can be used for the heat, but is it really efficient to have the cool air coming out of the floor also? Thanks.

Central Air Conditioning question... Do I need two separate units? My house has two separate forced-air heating systems. Each is completely independent of the other, both with their own ductwork, thermostat and furnace. The house, however, does not have central air. I'm looking to get this installed this spring. My question is.... will I need two air conditioning units or is there a way to have one unit services both HVAC systems?

how do I get air out of my force hot water heating system I have basebroad heat?

What is a typical cost to retrofit my home with a forced air unit with a geothermal heat pump system?

I have an exposed length of hot air ducting. If I use duct tape to seal the seams, can it withstand the heat? When the forced air gas heating system has been on for awhile, the exposed metal duct can feel quite hot to the hand, so I wonder if applying duct tape directly to a heated metal surface will cause problems. My ultimate purpose is to cover the duct with some kind of material which would provide insulation value.

Should I insulate the main air supply duct in the basement? I have a Forced Air Gas heating system, and I noticed that the main square air duct in the basement is getting fairly warm when the cycle is on. 1. Would I benefit from insulating it to allow more heat to travel into my rooms? 2. What material should be used? Thanks in advance! Now, that I have two opposite answers, I would like to know if the effort of insulating the main air supply duct is a good bang for a buck. No questions it would improve efficiency, but how much. I have to invest cost of material and tedious labour.
