What kind of furnace do I have? That is an essential question, especially when the heater isn’t working. 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 all room 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
An additional method 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 expensive to install.
You can have warmth 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 thing to determine is what fuel your furnace uses. There are six typical kinds.
Coal, not the typical, typically used with a boiler. If you have coal, you most likely noticed.
Electric heat is easy, but expensive. It’s one of the most expensive heat source.
Fuel Oil, If you’ve been in the house for some time then you may have filled 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 non-urban houses, with gas furnaces that don’t have gas piped to the house use propane.
Natural gas, or methane, that’s the gas which is piped to urban homes, It’s a very common way to heat houses. It burns clean, it’s fairly 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 outdoors.
That pretty well addresses it, if you reside in a house. Check Here for other home furnace information It should not take too long to nose around and determine where the heat is or should be resulting from.
