What kind of furnace do I have? That is an essential question, especially when the heater isn’t operating and you need heater repair. There are two common kinds of furnaces. There’s forced air and there’s the boiler type.
How do you determine which you have? It’s pretty easy. If you have “registers” in all space that have warm air blowing out of them, that’s forced air.
If one has radiators, either freestanding or baseboard type, 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 expensive to install.
You can have heat that’s not coming from a furnace. You could have electric baseboard heat. Or electric wall heating units. You could have a gas wall heater.
Next point to determine is what fuel your heater uses. There are six common types.
Coal, not the usual, generally used with a boiler. If you have coal, you probably noticed.
Electric heat is easy, but pricey. It’s one of the most costly heat source.
Fuel Oil, If you’ve been in the house for some time then you will have loaded a fuel oil tank. Generally used with a boiler.
LPG or propane. That’s an above ground tank that gets filled from time to time. Generally rural houses, with gas heaters 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 very typical way to heat homes. It burns clean, it’s relatively cost effective 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 pile of wood outdoors.
That pretty well covers 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.
