What kind of heating system do I have? That is an essential issue, especially when the heater isn’t operating. There are two common kinds of furnaces. There’s forced air and there’s the boiler type.
How do you identify which you have? It’s quite simple. If you have “registers” in each room that have warm air blowing out of them, that’s forced air.
If you have radiators, either freestanding or baseboard style, that suggests that you have a boiler
Another method to use boilers is radiant floor heat. That’s a lot of pipes that run through the floor and warm the floor up, which heats up the room. Very nice, but pricey to install.
You can have heat that’s not coming from a furnace. You could have electric baseboard heat. Or electric wall heaters. You could have a gas wall heater.
Next thing to determine is what fuel your heater uses. There are six common types.
Coal, not the usual, typically used with a boiler. If you have coal, you most likely noticed.
Electric heat is easy, but pricey. It’s the most costly heat source.
Fuel Oil, If you’ve been in the house for a while then you will have filled a fuel oil tank. Generally used with a boiler.
LPG or propane. That’s an above ground tank that gets filled every now and then. Generally country homes, with gas furnaces that don’t have gas piped to the house use propane.
Natural gas, or methane, that’s the gas that is piped to urban homes, It’s a pretty common way to heat houses. It burns clean, it’s fairly affordable and it’s generally pretty trouble free.
Wood, you probably noticed. You ‘d have a wood stove or a fireplace in the living room and a stack of wood outdoors.
That pretty well covers it, if you live in a house. It shouldn’t take too long to nose around and identify exactly where the heat is or should be resulting from. There are other articles at http://airconditioningrepairmarietta.org/
