Baseboard Radiator Heating
The first thing to know about any heating system is to understand a very basic scientific fact or a natural phenomenon that heat travels up in the atmosphere that surrounds it. The medium thru which heat travels is air generally. As hot air goes up, fresh cool air takes it place, which on getting heated up goes up and thus the cycle continues.
A baseboard radiator heating works on the same principle. The advantage of such a system is that all the paraphernalia of heating is installed beneath the floor, generally along the baseboard, thus keeping the floor and walls of the room free from any accessories that are usually associated with any other heating system. Here’s an outline on how it works.
Water is heated by using gas, oil or electric current on a system similar to but separate from the water heater that supplies your plumbing system. Water is heated in a boiler tank housed in the utility room, just the way it is used hot water plumbing in your house. Since the system is totally enclosed, there is no chance for dusty air being blown in thru the vents all over the house. Another notable feature is that the system is almost noiseless.
Water thus heated is circulated in the house thru a network of piping. So, naturally its circulation needs a motor and a pump. Next, we have radiators installed in different rooms. Hot water goes to the radiator, which on getting heated up radiates heat and thus warms up the room. The hot water on leaving the first radiator, goes to the next radiator in a different room and so on going to all the radiators in different rooms, heating each of those. Water is hottest on entering the first radiator. There is a slight drop in its temperature as it goes to the next radiator. In effect it means that the heated water is at its lowest temperature on entering the last radiator, from where it is fed back to the boiler system, which reheats the same for circulation. Now you can see it is a totally enclosed system in itself and the same water is used over and over again. To compensate for small volumes of water that are lost in the process, main water supply from the house is fed into the circulation system. It’s obvious that the room where the first radiator is installed will be the hottest. That’s why most of the house owners get the first radiator installed in the main room of the house.
If you come to think of it, the system has built in thermostats, as the temperature in no two rooms is the same. That would suit many families where each member likes to have a different temperature.
On the other hand you might call it a limitation of this system. But, not anymore, for now that limitation of varying temperatures in different rooms has been taken care to a good extent. Some of the modern systems are provided with control valves that may be so adjusted to let in a smaller volume of the hottest water in to the first radiator. Thus all the radiators will get a pre-determined volume of the hottest water.
The next question that comes to mind is: How do you control the temperature in your room when you are depending on hot water to heat the system? This is achieved by internally controlling the temperature of the boiler so that heat is available instantly when the room thermostat calls for it. As soon as you turn the thermostat on, the circulation pump gets a signal to start the circulation of hot water thru the house. Like any other heater you decide how hot you want it at any given time. Unless you happen to be at the end of the line of radiators, you can get the desired results.
