Ahhhhhhh...... You just found your culprit. Coolant flows in and out of those two hoses, into your heater core. Since coolant isn't flowing, you're not getting your heat. Looks like someone did a bypass on it.
And, I'd be willing to bet there's a reason someone did a bypass on it. Heater core "could" be faulty/leaking. If it's leaking, you'll need to pull the dash and replace it. You don't want hot engine coolant on the floor of the inside.
You won't know for sure if it's leaking/faulty, until it gets hooked back up properly. I can't think of a reason on why someone would bypass your heater core, unless it was leaking.
Did you recently purchase the vehicle?
