Well, these heaters didn’t save us any money. We just received a gas bill for $625. Yikes! However, in fairness to the heaters, let me list a few key facts:
• This bill was estimated; they didn’t actually read the meter last month but rather, they guessed at what it might read. They got it wrong; they underestimated our usage last month, so they billed us for the difference in this month’s statement, along with this month’s actual usage.
• To calculate your usage on an estimated bill, they consider the amount used last year, accounting for changes in average outside temperature between this and the previous year.
• It was eight degrees colder in January, 2009 than it was in January, 2008.
• Since the heaters are located in the basement, which is not insulated by the way, they had to work a little harder.
• Our primary heat (which is a 2004 vintage forced air gas furnace) is a high-efficiency model (91% efficient). The gas space heaters have a 99% efficiency rating. Some improvement, but not much really.
• We now enjoy a heated basement, which we didn’t have before.
• So, though the new gas heaters did way reduce the amount that the big furnace runs, they didn’t give any savings because we did not really replace a less efficient heat source with a more efficient one. So the gas heaters just took over making our heat, taking the load off of the main furnace. They don’t do it much better I’m afraid.
But what are nice with these gas space heaters, that we don’t get with the main furnace, are the warm floors on the first level, not to mention the heated basement space. That really takes the chill off throughout the house. Plus, our air is moister. So our noses don’t dry out and bleed as much, and static electricity is almost nonexistent when using these heaters. Now we do have to run the attic exhaust fan to keep the condensation in there down. But this only costs a few dollars a month in electricity, and it’ll probably cost even less once I install a humidistat on the fan later this year.
I’d say that though we didn’t get the money savings we’d hoped for, these heaters definitely improved the comfort level here in the house and keep us warm at much colder temperatures outside. Further, we have the added security that we’ll still get heat even during a power failure since these gas heaters require no electricity to operate. The main furnace however, does. So I’d highly recommend installing such units as a great do-it-yourself project. Just be sure to use black iron or galvanized pipe for all your gas runs, and dope all pipe fittings. Then, check them with soapy water for leaks once you apply the gas.
