Hydronic Heating Boilers: How Does It Make Your Room Warm During Winters?

Hydronic heating boilers are simply pressurized vessels used for heating water. This heated water is then passed through boiler tubes and the steam that is generated because of the heated water is circulated in a room or a building through radiators. The water can heat in a hydronic-heating boiler via various mediums like propane, natural gas, electricity or any other safe burning fuel. When you buy hydronic heating boilers, be sure to know about the nature of working of natural gas and also control the domestic applications of these boilers for heating your rooms.

It works with the help of a thermostat?
A hydronic-heating boiler simply heats the water to a temperature controlled thermostatically. This heated water is carried to convectors or radiators through plastic, copper or multi layer sealed piping. This water is carried back again for re heating.

  • The water is circulated through the piping by a pump. Heat is transferred into the room by the radiators or convectors.
  • Wall thermostats control the room temperature of the heat levels. Since these boilers are highly efficient and the heat produced is evenly distributed, each area in house or room can be controlled so that only the amount of heat required is used.
  • This saves your energy costs. The output of the boiler should be adequate to offset any heat loss as well as any extra heating needs such as a pool, hot tub or garages.
  •  Hydronic heating boilers can have both variable temperature controls as well as constant temperature controls.

The temperature fluctuations that matter a lot:
The intensity of water heating or boiling in a hydronic-heating boiler is very low. The heating temperature in this kind of a boiler is usually limited to 180 to 200 degrees Fahrenheit. Typically, a hydronic-heating boiler requires other boiler accessories like an expansion tank, a circulator, a motorized pump and flow check valve. The motorized electric pump is required to circulate the hot water. A hydronic-heating boiler must always be filled with water completely. These boilers usually have a device for regulation of temperature called an aqua stat.

This aqua stat controls the temperature of the boiler and also acts as a transformer working at a low voltage and thus controls the circulator.

  • A hydronic-heating boiler also incorporates a regulator or a valve, which keeps the pressure of the water under check.
  • The check valve, also called the backflow preventer prevents the water in the boiler to migrate back to the supply water in cases where the pressure of the boiler rises more than the pressure of the domestic water.
  • The entire system temperature and pressure are kept under the maximum limits with the help of a temperature pressure relief valve. The expansion tank helps in the contraction and expansion of the water, which is dependent upon whether cooling, or heating effect is applied.
  • The boiler also consists of a coil inside it, which circulates the hot water from the boiler. This coil is used because it is not possible to draw the boiled water directly from the boiler due to the chemicals present in the boiler used for preventing corrosion.

Hydronic heating boilers are considered to be very safe in use and operation. However, it is important to use the appropriate size of the boiler. Usually the power of the boiler should be slightly more than the maximum required power for the hydronic heating system. An oversized boiler will lead to extra consumption of fuel and the boiler may turn on and off again and again. This will not only lead to wear and tear of the boiler but also cause heat loss. A hydronic-heating boiler can be placed anywhere. It is important to however provide adequate protections against freezing.
