What kind of furnace do I have? That is an important issue, especially when the furnace isn’t operating. There are two typical 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 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.
Second point to figure out is what fuel your heater uses. There are six common types.
Coal, not the typical, typically used with a boiler. If you have coal, you probably noticed.
Electric heat is simple, but expensive. It’s the most expensive heat source.
Fuel Oil, If you’ve been in the house for a while 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 now and then. Generally non-urban 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 pile of wood outdoors.
That pretty well addresses it, if you reside in a house. It should not take too long to nose around and figure out where the heat is or should be coming from. Click Here for more Central Air articles
