My home was built in 1957, I had a new heat pump system put in (which I now hate) 7 years ago. It works fine in the summer, but in winter it doesn't heat the house very well.

At the time, I kept the old Coleman, through the wall natural gas heater as emergency heat, as works without power to the house. It's old and inefficient, but it's done it's job for 50+ years. This year I replaced the old thermostat,with a new Honeywell round heat only mode. I haven't been able to get it fired up once this winter though. I've contacted a couple of local heat/air places, and noone has ever heard of this heater and don't know how to service it apparently.

So I'm trying to troubleshoot it myself and see if the problem is the thermostat, or the unit itself. Am I correct in thinking that if I manually touch the two wires together (red/white), sans thermostat, the unit should come on if it's going to?

I'm hoping to install a tankless water heater, and I'm trying to figure out if my current gas meter can handle it. So I'm trying to figure out how much gas my furnace uses.

It's a Goodman GMH950703BXAD. The label says the max temp rise is 69,000 BTU/hour, and the EnergyGuide sticker says it's 98% efficient. Am I right in thinking this means a max gas usage of about 70,500 BTU? (69000 / 98) * 100 = 70408

The gas meter usually is not the problem it is the gas line either through the house or the connection size and the size of the line you install. A minimum 3/4" gas line to the new water heater is required. And the line you pipe into should be at least 1 inch. Any thing smaller and you will not have enough gas flow. The main gas line in the house should be at least 1 inch. You could call the gas company and see if they can raise the gas pressure to your house. 8 ounces used to be the...

During the preparation of our journey we checked out an army surplus store. Here bought a sturdy aluminum navy frying pan and a waterproof storing box to put on the Land Cruiser’s roof. We hadn’t talked about what cooking equipment we’d bring. We wanted to keep things simple and didn’t want to build a kitchen inside the Land Cruiser. We wanted to be able to cook inside as well as outside.

I was scanning the shelves when all of a sudden my eyes fell on a couple of rectangular, green metal boxes. When I opened one of them, I knew we had found our kitchen set-up. Two old Coleman 425F stoves were stacked between a number of military diesel stoves. These old models, with the fancy red tank, appealed to us so we bought one. On the road we have came across numerous overlanders using the newer 424 model (find it here).

Hi, Your question is a good one and I'll attempt an answer that is worthy. In wall units are exactly what they say and can be either forced draft ( use a fan motor ) or just use natural draft for air movement. In wall units are not favored in my book, ( But ) They definetely do have their place in the world. I have many reasons for saying this so I'll just touch on a few. Safety !!!!!!!!!,,,,,,,, flue pipes that vent off your heaters fumes often rot out because one of the flue gas byproducts is water and that eats away at the often sheet metal vent pipes from inside out and you can't see them inside your walls very easily. Efficiency !!!!!!!!!!!,,,,,, typically not nearly as efficient as a central type heating system. Note: I have personally witnessed several cases where people using in wall gas units had fires in their in walls and the wood was badly burned without them even being awares. The only thing that seemed to keep them from turning into a roaring out of control fire was...

Coleman used to make some pretty cool liquid fuel heaters. These were catalytic heaters, so theoretically, you could use them inside a large tent.

Around here where many people hunt in cold weather and ice fish, there are many of these available now at garage sales, thrift stores, and Craigslist. Some are in excellent condition and some don't work, but most are very easily repaired.

Last year, I bought one of these heaters and found it full of kerosene. I put new fuel in it and struggled to make it work - extra heavy priming, you name it. Nothing. So I bought another one - this one didn't work either. What a frustrating disappointment.

I was ready to toss them, but then I read an article on kerosene catalytic heaters that people use in their homes and learned about the maintanance that is needed.

Low and behold, the solution was simply too easy. There is a wick inside that needs to be trimmed or replaced.

Because there are several different models, I...

Greg Shreeve, energy expert at the Energy Saving Trust, says if you do turn your thermostat up even higher, you'll probably simply "find it's a bit too hot" - and you'll have wasted energy and cash in the process.

Myth 2: Turn up the thermostat to heat the room more quickly
(35 per cent of people do this)

If you come home to a chilly house it may seem tempting to turn the thermostat up to maximum - but it won't get you back up to a comfortable temperature any sooner.

"People think it's like pressing your foot down on the accelerator in a car, and the further you press your foot down, the faster you get to the speed you want," Mr Shreeve explains.

"But actually, a thermostat doesn’t control the speed at which your house heats up - it just controls the final temperatures."

So you won't get to the temperature you want any sooner - but you will end up with an overly-warm house, unless you turn it back down in time.

About time! Astounding heat output for the cost!

Posted by Corinne Guilmain on 12th Apr 2018

Wow. I love this heater. I only have one unit but I plan on buying at least several more. I put together a monthly heating bill for my house in Vermont. It looks like this. The floor plan here is open concept, long, with 3 bedrooms, a sunroom with all 3 sides in windows. This measures at 41 feet wide and 27 feet long. There is an attached enclosed room with no heat that measures 24 feet wide and 27 feet long. It is 48 degrees outside. The attached room with no heat measures at 62 degrees and the house measures at 71 degrees. There is a wood stove that is barely staying alive and hardly any heat is coming out of it. This is so if this experiment fails, I don't have to restart the stove. One unit is placed centrally in the house. So the figures I've given you are absolutely, in my opinion, astounding. But I have a question. How much is all of this going to cost? I just...

We have a gas fired water heater, and a gas furnace with hot water rads.

During the recent ice storm, we were without power for 4 - 5 days. I assumed that both the furnace and water heater would not work, even though both pilot lights remained lit. But I was only half right - after a couple of days, I discovered we still had hot water available.

I'm no HVAC expert, but the two appliances seem largely the same in principle; i.e., a thermostat-controlled gas burner that heats up water. So why does only one of them continue to function without hydro power? Of course, the thermostats are different, but our furnace is controlled by a digital setback thermostat upstairs, and it continued to work (or at least the digital display did) from its backup battery.

Our heating system also has an electrical circulation pump to move the water through the rads, but it seems this would not be a show stopper, since simple convection should do at least a partial job of...

We sized up various heating devices to determine which will keep you the most cosy for the least cash

Last Updated: 15 May 2017

One of the first things we Capetonians do when the weather starts to turn a little nippy is hauling out the old heater – it’s a sure-fire way to defrost those icy fingers and toes quickly and conveniently. The only issue is that it can also be an uber expensive option. According to Eskom, domestic space heaters can account for up to 16% of your electricity bill, so if you’re going to use one (and let’s be honest, no one’s willing to give theirs up), it’s important to choose the most energy-efficient of the lot and to employ it in the right contexts in order to bring down costs.

To help you save some dough this drizzly season, we chatted to the folks at Eskom and, with their help, put together a comparison below that outlines various heating options and the pros and cons of each. This way, you should be able to make a safe,...

I assume you are dealing with a gravity wall furnace, now made by Williams and Empire, and commonly found in California. They require no AC power. They use a thermocouple on the pilot light to power (via the thermostat) a millivolt gas solenoid. They sell special thermostats for this application. A "common" thermostat may or may not work, depending on its ability to switch a very low voltage at comparatively high current, and function without 24v power.

Electronic thermostats cannot work, unless you supply 24v to them and supply a relay to switch the millivolt line... but that makes the furnace dependent on AC power, which defeats the purpose of this type of furnace!

Yes, touch red and white together, and the unit should come on.

If it does not, first check that the pilot is on (no pilot, no millivolts). Then check the 2 wires with a voltmeter, there should be some fraction of a volt of electricity. If not, the pilot is out or you have a thermocouple...

Common Thermostat Problems...more advanced to follow, but start with the basics first.Work with the power off whenever possible.When a furnace does not work it may be caused by problems with the furnace or the thermostat.

Before troubleshooting your thermostat, check to see if all filters are clean and all hoses to and from the units themselves are free of wear.
If these are not causing problems, then it is time to look at specific thermostat issues and possible solutions.

Your thermostat could have aging wiring that is faulty or the transformer may require replacing.

A thermostat may need cleaning to eliminate erratic operation.

Accumulated dust is a common culprit.

First, you should have a small paintbrush, a screwdriver, and a voltmeter.
The

anticipator is a small metal tab positioned in front of an arcing printed scale. Give it a light push in both directions. This easy step may solve the
problem.

Gas Furnaces and Heating Systems

Home heating is an essential part of comfortable living. The question is what kind of furnace and heating system is best for your home. From small portable heaters, to central furnaces, or even heat pump systems that effectively let your air conditioner run in reverse there are lots of options available to the Australian consumer.

Types of Gas

There are two main types of gas in use in Australia: LPG and natural gas. LPG, or liquefied petroleum gas, usually transports in bottles. Another common name for it is propane, and it often pairs with barbecues. Natural gas is methane, and is what usually flows through the gas mains to your home. LPG has more energy than natural gas, but also needs more oxygen for combustion.

Advantages of Gas

The big advantage of gas heaters is that they warm up fast. Electric heat is generally slow and uses a lot of energy. Gas furnaces and heating systems start producing heat the moment you light...

Fixing a gas furnace: this is a real-time look at how I'm keeping warm until the new gas valve comes. Sorry about the poor camera work! I missed the "money shot" at the end, but you'll get the idea!

Edit 2015 11 15: Really, this is a crappy video. The bottom line is that if your gas valve is not opening, if you give it a very little hit with a wrench, it might give you heat for the night until "the man" comes the next day. Of course some people say that comes at the expense of getting blown to high-heaven. I personally am not in the '"blown to high heaven" camp. These valves are designed to "fail closed" of freakin' course! That's probably why the valve is not opening...because it's being conservative, lol!

Edit 2015 11 15B: I just watched this again after not watching it in 5 years. It's not so horrific as I remember. Yes, I don't show me hitting the valve with the wrench, but I did put "BANG" up there,...

Let’s start with a few definitions.

Appliances include fireplaces, woodstoves, furnaces, boilers, pellet stoves, hot water heaters, etc. They’re all individual appliances.

A chimney is a structure that has one or more flues in it.

A flue is simply the chimney passageway that vents the fumes from whatever is attached to it. (A flue is not the same as a damper either; a damper is something that can block the flue.)is simply the chimney passageway that vents the fumes from whatever is attached to it. (A flue is not the same as a damper either; a damper is something that can block the flue.)

How many appliances can you have per chimney?

And even though the question always comes across as “how many on one chimney?” let’s make sure to discuss “how many on one flue?” The answer to the question is: “It Depends”.

The rules are found in various NFPA standards and in the IRC (International Residential Code.) This article is general in nature but for...
