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. Types of fired heaters Texas City.
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. Types of fired heaters 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. Types of fired heaters Texas City
Material
There are several materials with which the heater can be manufactured. Types of fired heaters 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. Types of fired heaters 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. Types of fired heaters 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. Types of fired heaters 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.

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. Types of fired heaters 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. Types of fired heaters 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. Types of fired heaters Texas City

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.

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. Types of fired heaters 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. Types of fired heaters 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. Types of fired heaters Texas City

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. Types of fired heaters 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. Types of fired heaters 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. Types of fired heaters 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. Types of fired heaters 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. Types of fired heaters 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. Types of fired heaters 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. Types of fired heaters 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. Types of fired heaters 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. Types of fired heaters Texas City
- Remember! Do not cover the heaters since you can hinder the transmission of heat and it supposes an energetic waste. Types of fired heaters 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. Types of fired heaters 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. Types of fired heaters Texas City.
