What kind of heating system do I have? That is an important issue, especially when the heater isn’t operating and you are about to call heater repair.. 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 pretty easy. If you have “registers” in all room that have warm air blowing out of them, that’s forced air.
If you have radiators, either freestanding or baseboard style, that indicates that you have a boiler
An additional way to use boilers is radiant floor heat. That’s a bunch of pipes that run through the floor and warm the floor up, which heats up the room. Very good, 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.
Second point to determine is what fuel your furnace uses. There are six common types.
Coal, not the typical, typically used with a boiler. If you have coal, you most likely noticed.
Electric heat is simple, but expensive. It’s one of the most expensive heat source.
Fuel Oil, If you’ve found yourself in the house for some time then you may have loaded a fuel oil storage tank. Generally used with a boiler.
LPG or propane. That’s an above ground tank that gets filled every once in a while. Generally rural 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 homes. It burns clean, it’s relatively affordable and it’s generally pretty trouble free.
Wood, you probably observed. You ‘d have a wood stove or a fireplace in the living room and a pile of wood outside.
That pretty well addresses it, if you live in a house. It shouldn’t take too long to nose around and determine where the heat is or should be resulting from.
