If you use a boiler for heat, then you probably have forced water radiators as the actual heat source in your rooms. There are different ways these radiators could be set up. They could be set up like the old-fashioned style standing radiators. Or, they could be set up in the more common baseboard radiator style. These radiators are basically long pipes that fill with hot water. The pipes run through a series of small metallic fins, which radiate the heat out into your room. These pipes depend on the hot water running through them in order to create that heat--without that heated water, your rooms will start to cool. If your thermostat is turned up, but your room is still cold, you may have a leak somewhere in your radiator system. But, how can you be sure that you have a leak?
One way that you can tell that you have a leak in your radiators is that you keep running into odd, cold puddles. They are odd because they will seem like they are in random areas. There is no sink around them, the ceiling and walls don't seem to be affected, you just have a puddle of water on the floor.
Generally, the puddle shows up because the pipe has cooled down. When the pipe cools down, it contracts. Any small holes or problems with the joints in the pipes will then be exposed. The heated pipes expand just enough to make any gaps close.
Rust is formed when water sits on metal. If your radiator has a small leak, you might not see a noticeable heat loss, or have a random puddle in your room. The radiator may just have a tiny, pinprick leak, just enough for some water to get out and rust the metal around the radiator. The rust stains may also show up on the wall around the radiator.
If you think that you have a leak in your radiator system, you want to have a plumber, like those at Boiler Services, Inc., come in and look at it as soon as possible. That's because the water leaking out of the system is going to cost you money. A leaky radiator can also cause physical damage to your house. All that water can rot carpets, cause mold, and warp your subflooring. It may take the repair person some time to track down the exact spot of the leak, but once they do, they will be able to fix the problem.
