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. Radiant tube heater problems 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. Radiant tube heater problems 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. Radiant tube heater problems 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. Radiant tube heater problems 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. Radiant tube heater problems 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. Radiant tube heater problems 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. Radiant tube heater problems 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. Radiant tube heater problems 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. Radiant tube heater problems 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. Radiant tube heater problems 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. Radiant tube heater problems 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. Radiant tube heater problems Texas City.
Pellet stoves
For the current price of pellets are relatively cheap, but you have to provide a lot of fuel. Radiant tube heater problems 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. Radiant tube heater problems 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. Radiant tube heater problems 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. Radiant tube heater problems 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. Radiant tube heater problems 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. Radiant tube heater problems 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? Radiant tube heater problems 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. Radiant tube heater problems 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. Radiant tube heater problems 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. Radiant tube heater problems 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. Radiant tube heater problems 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. Radiant tube heater problems 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. Radiant tube heater problems Texas City.
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. Radiant tube heater problems 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. Radiant tube heater problems 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. Radiant tube heater problems 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. Radiant tube heater problems Texas City.
I turn on the heater or is it still early? Yes, there are also rules for that
9 tricks to heat the house without turning on the heater
Take advantage of sunlight: it’s as easy as closing blinds and running curtains at night. The objective is to achieve a maximum sealing of the house so that it does not get cold. During the day you have to open them to let in the sun’s rays, with them warmth enters and helps to increase the temperature. Radiant tube heater problems Texas City.
Ventilate the house: even the days of intense cold. It is important to ventilate to maintain the temperature and renew the air. With 5 or 10 minutes it will be enough Radiant tube heater problems Texas City.
Check your heater system: at least once a year check the heater because it is important for a professional to take a look. Spend a little today can avoid more expensive future arrangements. Radiant tube heater problems Texas City.
Maintenance of the heater system: besides the revision there are heater systems that need some maintenance. They are usually small, simple tasks that range from purging the heater once a year to cleaning the ventilation ducts. Knowing well the system used by your home is key to proper maintenance.

Types of heater
The heater can be divided into two large groups: those that act as heat exchangers and those that generate heat themselves. The first is a water heater, which receives hot water from a boiler and is responsible for dissipating that heat to the environment. Radiant tube heater problems Texas City
Types of the water heater
The heater that carries water inside is used for installations with natural gas boilers, biomass or even in aerotermia systems. In this last case it is a heat pump that heats the water that will later reach the heater. Radiant tube heater problems Texas City
Material
There are several materials with which the heater can be manufactured. Radiant tube heater problems Texas City
Steel panel heater
They are also called sheet metal heater, since they are formed by sheet metal panels. They are more economical than the rest and can be formed by vertical elements or be a smooth or grooved set.
The response speed is very high. Radiant tube heater problems Texas City
Aluminum heater
They are, together with those of steel panel, the most used option. They are lightweight, can have the front open or closed and have good resistance to corrosion.
They have very high response speed. Radiant tube heater problems Texas City
Cast iron heater
This type of heater is tending to disappear due to its high price. They are formed by cast iron and can be seen in some places that want to preserve the retro look they have. They are very resistant.
It has a medium response speed. Radiant tube heater problems Texas City
Temperature
The heating until a few years ago was almost exclusively high temperature. The common thing was to have an average temperature in the heater of 70 ºC causing the boiler to heat the water to 75 ºC. This gives a thermal jump of 50 ° C (taking as ambient temperature 20 ° C).
But in the last few years heating at low temperature has taken center stage. The RITE has already lowered the working temperature of the heater to 60 ºC (which means a thermal jump of 40 ºC) and the studies indicate an important energy saving in heaters dimensioned to work at low temperature. Radiant tube heater problems Texas City
High temperature
In the high-temperature heating, any of the heaters described above may be used. They emit heat both by radiation and by convection and can easily withstand working temperatures. Radiant tube heater problems Texas City
Low temperature
The same heater designed for high-temperature heating can be used at low temperatures. A larger area will be necessary to reach the necessary power in a house due to the lower water temperature, but there is also heater designed for low temperatures.
Low temperature heater is characterized by very low water content and maximizing the exchange surface. To achieve this, they are manufactured with copper tubes through which the water is passed. Radiant tube heater problems Texas City
Although it has increased the exchange surface are heaters that emit less heat due to the low temperature of the water. To avoid having to increase the number of elements to be placed, small fans are incorporated and activated at the most demanding times. In this way it is possible to reduce the size of the heater with respect to those of high temperature. They would be called dynamic low temperature heater.
These heaters will become more popular. They are valid for condensing boilers, achieving significant reductions in consumption, as well as for heating systems with heat pump, solar thermal or geothermal energy. Radiant tube heater problems Texas City
Heater Ferroli low temperature
Types of the electric heater
Another option to heat a house with heater is the electric ones. Unlike the water heater, the electric heater generates heat and does not act as an exchange.
It is normal to consider installing this type of heater since their cost is lower and you do not need to do work, just fix them to the wall and plug them in. But it should be noted that this technology is the most expensive to heat a house. The savings in the installation will be exceeded by the high power consumption that this heater will have. Radiant tube heater problems Texas City
The main difference between the different types of electric heater lies in what they contain inside:
Air
They are called convectors and their operation is very simple. By means of an electrical resistance they heat the air that they have inside and it rises due to its higher temperature. They can be fixed or mobile.
These heaters stop emitting heat as soon as they are turned off. Radiant tube heater problems Texas City
Heat transfer fluid
They are heaters that have a heat transfer fluid inside. The normal thing is that this fluid is oil and is used with the objective of delaying its cooling once turned off. Two designs can be differentiated:
With wheels: for greater comfort when moving them. Radiant tube heater problems Texas City
Oil heater
Anchored to the wall: they bring some supports to fix them to the wall. They are more aesthetic and usually bring a programmer. Radiant tube heater problems Texas City
Electric heater wall heat transfer fluid
Related: Blue heat heaters, what are they really?
Ceramic
The principle remains the same: an electrical resistance that heats up as electricity passes through it. But these types of heaters have a ceramic material inside that will delay the cooling once turned off. It will keep heat longer than heaters with heat transfer fluid, although it will take longer to warm up. Radiant tube heater problems Texas City
What should be taken into account regarding the central heating heaters?
At this time of the year where households receive a greater number of visits and family meetings are the order of the day the central heating is at full capacity. For everything to work properly, the heaters must be in optimal conditions to achieve a comfortable temperature for the whole family. Radiant tube heater problems Texas City
Does the material the heaters are made of influence?
The same powers can be achieved with heaters of different sizes depending on the material they are manufactured from and their physical configuration of the space to be heated. Radiant tube heater problems Texas City
Where should the heaters be placed?
The most appropriate place for the installation of the heaters, from the point of view of comfort, is in the coldest wall of each room.
This wall is usually the outside and the heater must be placed under the window, which reduces the cold wall effect (feeling cold when we approach a window). In some cases it is recommended to place an insulating material on the wall in order to reduce the heat losses to the outside. Radiant tube heater problems Texas City
Are the heaters of a bass, a third floor and the last floor the same?
Experts recommend that heaters in homes located on lower and later floors be larger than similar ones in intermediate floors, due to heat losses through the floor or ceiling. Radiant tube heater problems Texas City
What does the healing power of the heaters depend on?
The healing power of the heaters depends on the temperature of the water that reaches them from the boilers, the flow that circulates inside them and the ambient temperature of the space where they are located.
This power increases as the water temperature increases or when a higher flow rate circulates, while it decreases when the temperature or flow rate does. The heating power must be able to cover the needs of the building when the outside temperatures are very low. Radiant tube heater problems Texas City
We must make good use of the central heating heaters
As we have pointed out on previous occasions, a good use of central heating heaters also implies good maintenance, so it is appropriate to follow a series of guidelines:
- Keep the heaters clean but be careful! Better to do cleaning tasks when they are not working and are cold. Radiant tube heater problems Texas City
- Purge the heaters at least once a year; the air that accumulates inside can make it difficult to transmit the heat from the hot water to the outside. Radiant tube heater problems Texas City
- It is convenient to perform a hydraulic balance to confirm that all heaters receive the water they need to operate. In this way the neighbors of the first and last floors can have a comfortable temperature in their homes. Radiant tube heater problems Texas City
- Remember! Do not cover the heaters since you can hinder the transmission of heat and it supposes an energetic waste. Radiant tube heater problems Texas City
How to modulate the power of the heaters
You can modulate the power of the heaters through the detector, which is the key that regulates the entry of water into the heater.
Close the detent slightly on the heaters that heat the most. With half a turn to the right there will be enough. Radiant tube heater problems Texas City.
Open the detector in heaters that do not heat well. If they are already open to the maximum, keep closing those heaters that have been heated before.
This operation takes some time but in the case of old or badly designed installations is the only way to level the heating circuit. Radiant tube heater problems Texas City.
