Efficient Central Heating Needs the Right Thermostat for the Job

By Tal Potishman

As the temperature drops, proper central heating becomes more and more important. Ensuring that your central heating system is working correctly should be a top priority for you and your family with a single faulty part capable of ruining your winter holiday season. There are a number of issues that can surface during the cold winter months. One common issue is frost damage, which can harm boilers and pipes, preventing them from working efficiently.

In the past, the central heating system was set up so that the frost thermostat was placed near the boiler. It was responsible for turning on the boiler as the ambiance temperature dropped below the determined level and heat was needed. The thermostat also stopped the boiler when it detected the air temperature was at an appropriate level. Many times the thermostat detected heat leaking from the boiler or the pipes and immediately turned off the system to conserve energy.

A new development in insulation materials for central heating systems has made the frost thermostat's job much more challenging. Modern boilers and pipes are much more insulated than their older counterparts. Energy conservation was the goal of this alteration; unfortunately the problem of overheating persists. The frost thermostat is no longer able to detect changes in temperature accurately. As such, overheating and energy waste continue to occur.

A pipe thermostat can be one simple solution. This device is positioned directly on the boiler return pipe. This thermostat measures the pipe temperature and shuts off the boiler in the event of overheating. There are a number of new products that contain both a frost thermostat and low limit pipe thermostat. These products provide the ability to control room temperature and provide protection from frost.

Installation and set up of these new thermostats is simple and quite intuitive. Guidelines for complete wiring and installation arrive in the kit, ensuring simple installation. The frost thermostat is usually set to 5C and the pipe thermostat is commonly set to 25C. Additional pipe thermostats can be bought for other exposed pipes, to further insure that your system is completely protected.

If the pipe thermostat fails to meet your needs, there are other solutions. A fully programmable room thermostat is one option. These devices can be installed in a number of locations throughout your home, usually in a living room or bedroom. Their job is to measure and monitor the temperature of the room. The thermostat can be set to change the room temperature several times a day, depending on the homeowner's needs. There are several kits that operate by means of radio signal, from the thermostat to the boiler. These Radio Frequency (RF) thermostats require no wiring, which makes them very easy to install.

Thermostats are an important element of your home heating system but, there are other variables that impact your heating efficiency. By sectioning the home off into zones, waste can be avoided. The use of zones, allows you to focus the heat where you need it most. More populated areas can be kept warmer than empty rooms that do not require as much heating. This minor change can produce great results. Not only will heating bills be lower but, system efficiency will be greatly improved. - 17607
