Heater systems
As a professional of the air conditioning I want to make a small outline about the types of heater systems that exist for your home or business premises, in order to keep you informed before the cold weather arrives, so that you will not be caught unaware. Fired heater operation Texas City.
Thermal emitters or heater
It is the union of several aluminum elements, with internal channels to circulate the air.
Normally they carry oil inside that is heated by an electrical resistance. Once its elements are heated, the air in contact with the surface heats up and rises naturally and finally continues up to the ceiling, where it is kept heater until it cools and falls down. Fired heater operation Texas City.
That’s why it takes so long to heat the rooms.
Like other similar systems, it produces a large temperature differential in the rooms. Very low on the ground and very high on the roof.
The heater emits some short-range infrared radiation. Consequently, they produce few results in direct heat. Fired heater operation Texas City.
Heater with boiler
They work like thermal emitters but instead of running on oil, they use water.
The way to heat the water can be by gas oil, gas, coal, fuel, pellets or other fuels. Fired heater operation Texas City.
They take longer to warm up because of the large amount of water and mass that the system has. In addition, heat and energy losses occur in the boiler and in the ducts.
There is also a large thermal differential between floors and roof in the rooms and its level of infrared emissions is minimal. Fired heater operation Texas City.
It must be said that the longer it takes to heat a room, the more fuel consumed, and therefore the expense.
Convectors
Its shape is a metal box that incorporates electrical resistances. In some cases they also carry a fan that forces the passage of air. Fired heater operation Texas City.
They are somewhat faster because the electrical resistance directly heats the air but, they produce less infrared radiation.
This system and the two previous ones use too much energy for the dynamic behavior of hot air, and that is that most of the energy consumed stays below the ceiling, where it has no use. Fired heater operation Texas City.
And therefore, the hot air that is placed under the roof does not heat our legs or our feet. Thus, we have cold feet and a hot head.
What happens then with the air?
The hot air is lighter than the cold and therefore goes up to the highest parts of the rooms, once there, in contact with the surfaces that are still cold begins to lose heat. Fired heater operation Texas City.
Soon, the air will have cooled and therefore it will become heavier and lower again to the ground, but without the ability to heat anything.
When it is sucked again by the heater, it will heat up and regain its heat on the ceiling. Fired heater operation Texas City.
The downside of this is that each liter of air weighs less than 1’3 grams, so to heat the thousands of kilos of the mass of the walls, floor and ceiling; you will have to repeat this cycle thousands of times.
When the room is finally tempered somewhat, the process will continue, but there will be a great temperature differential between the floor and ceiling and we will still feel cold in parts of the body. Fired heater operation Texas City.
Also, in places with high ceilings, the differential will be even higher. With this, it will be almost impossible to reach the minimum comfort.
The fact is, the air will continue in this process, going up hot and cold down, all the time, losing moisture and vitality, while we continue to inject more and more energy and money, to have a warm head and cold feet. Fired heater operation Texas City.
Air conditioning by the heat pump
By its system, which consists of the compression and decompression of a gas, it consumes less energy than systems with resistance or combustion.
However, its performance drops considerably when outside temperatures are cold. Fired heater operation Texas City.
Pellet stoves
For the current price of pellets are relatively cheap, but you have to provide a lot of fuel. Fired heater operation Texas City.
But what are pellets?
The pellets are a completely natural product, classified as solid biomass, which is formed by tiny cylindrical pieces of a few millimeters in diameter taken from renewable materials. Fired heater operation Texas City.
This type of fuel based on pellets is taken from wood, and is usually obtained by pressing vegetable waste such as sawdust. Since pruning remains can be used, cutting down trees are not necessary.
One of the disadvantages of pellet stoves is that they are very sensitive to winds. Fired heater operation Texas City.
Wood Stoves
The cost of consumption of this method varies depending on the price of the wood used.
The bad thing about this system is that it dirties the walls, adds dust from the ash to the environment and you have to be aware that it does not go out. Fired heater operation Texas City.
Gas Stoves
The worst thing about this system is that there is combustion of the gas in the room to be heated, without gas evacuation. Fired heater operation Texas City.
This causes some inconvenience, and is that the oxygen combustion of the place alters the natural balance of the air we breathe, and expels in the same place the gases resulting from combustion (carbon dioxide, carbon monoxide, etc.).
As carbon dioxide weighs more than air, it goes down and takes the place of the air we must breathe. Fired heater operation Texas City.
That is why we say that it is a partially dangerous method. Although if proper ventilation of the room is carried out, no problem should arise, when heat is lost.
Infrared electric heaters, shortwave
This type of infrared has a very short life, and is that they die soon. That is, they cover very little distance.
Practically does not heat the environment, only when we are near them, therefore consume too much energy, without very satisfactory results? Fired heater operation Texas City.
Radiating floor
It is one of the most efficient systems, and its operation is not based on the heater the air, but the energy is obtained from the water that circulates through tubes that are in the concrete. Fired heater operation Texas City.
Thus a large surface is obtained as an element that emits heat.
The advantages of this method are numerous: energy saving, it does not suppose an alteration of the aesthetics of the house since it is installed under the floor, the temperature that is produced is uniform, that is to say, there is no higher temperature in certain places in the home, and finally, it is a type of heater that does not dry out the environment.

Afraid to turn on the heater?
The good temperatures of the year are lengthening in autumnal months but it will be inevitable to turn on the heater in the coming days. Sheltering us from the cold makes our bills bigger, how much does it cost you to put the heater?
The tricks and tips to spend as little as possible on heater are varied and with different effectiveness. We summarize the most important so that this year the heater bill does not rise to the clouds. Fired heater operation Texas City.
The quality of housing
The choice of a home goes through the right combination of location, size and price. The quality of the construction is a fourth basic characteristic to keep in mind that is usually forgotten. A well-insulated building with good materials and good orientation can have direct savings on air conditioning, damage and, of course, heater. Fired heater operation Texas City.
Isolation: asks what kind of insulation the house has. The basic thing is that there are on the walls and on the floor. Pay special attention to the floors that are on the ground, such as the garage of a house. If the house is well insulated, the interior temperature will be better controlled since the impact of the outside temperatures (the cold in winter and the heat in summer) go down.
Windows are another element that protects interior temperatures. The basic thing is that they are well placed so that no air enters through a hole. It is also recommended that it has double glazing because the inner chamber that remains between them works as an insulator between the inside and the outside. Fired heater operation Texas City.
Check slits: a small space that allows the wind to pass can lower the indoor temperature by several degrees. As a result we will have to give intensity to the heater and increase the expense. Check ventilation ducts, windows, doors or balconies to make sure everything is sealed. Fired heater operation Texas City.
Heat points: the place where the heat points are located (heater, heat pump, chimney …) directly influences the efficiency of the system. The heater is usually placed under the windows, where it is transmitted cold, so that it is instantly hot. The radiant floors make a very homogeneous distribution; but remember that wood does not transmit heat. If there is parquet flooring in rooms with underfloor heater, ask what material is made of.

The right temperature
The degrees: Choosing the right temperature is important to control consumption, it is not about going in short sleeves in the middle of December. The IDAE recommends a temperature between 19º and 21º during the day and at night it is sufficient to keep it between 15º and 17º. For each degree that increases, the energy consumption is increased by 7% and the bill goes up.
The proper temperature of a house during the day is between 19 and 21 degrees. Fired heater operation Texas City.
The thermostat: if your system does not have a standard thermostat invested in one to control the temperature of the house every minute. Changing the temperature between night and morning automatically is easier and we avoid forgetting. In addition, it may be interesting to select a thermostat with remote control, for example if you travel a lot, to turn on the heater with time and when you get home warm. Fired heater operation Texas City.
Adjust the temperature to your schedules: the generic recommendations will vary depending on the habits. For example, the temperature of the day (between 19 and 21 degrees) should be what we notice when we get out of bed and we have to program our heater system for it. The schedule directly influences the time of planning the schedules of turning on, off and readjusting degrees. Fired heater operation Texas City.
The habits
The little things we do every day over many days can help improve the energy efficiency of the home but also make it worse. The idea is to encourage good habits to reduce the bill. Fired heater operation Texas City.
