You are running the hot water to warm the room, right? Don't put them in hot water.
Getting them dry and reasonably warm (50 to 60F) first, is good. Their normal body temp should be a little over 100F, but I think that raising their temperature too quickly will not be the best thing to do. Warm them up, but not too quickly.
How are they behaving now? Still shivering?
Lukewarm water - to drink - will help warm them up from the inside. It will take some time.
How is their breathing? Can they stand, hold their heads up?
Do you have poultry vitamin powder? If so, mix that into some lukewarm water and let them drink from that. If not, apple cider vinegar - a tablespoon in a gallon of water - will probably help.
I'd fix up a spot in a warm room where they won't be disturbed with some dry towels or similar bedding that can be fluffed up against them. They may revive quickly - hard to say - or it may take a while.
Once they're sitting up, drinking, doing normal ducky things, I'd give them just a little moist food and see if they'll eat. Some encouraging sounds from you will likely help.
