Heating and cooling systems are an integral part of the design of any house. With changes in weather, you always need to have a comfortable atmosphere inside to allow you to withstand the harsh temperatures. These systems have 3 main components that include a source of air which can be warmed or cooled, a way of distributing that air into all the rooms that require it and a control device such as the thermostat to regulate the temperature to your liking. Heating and air conditioning work on the theory that heat moves from an object with higher temperature to an object with lower temperature similar to water flowing from a higher level to a lower level. Heaters are used to put heat into the air inside your home to make it warmer while air conditioners do the opposite by removing the heat to make a room cooler. Both these systems need some sort of fuel to operate. Air conditioning requires electricity and most heating systems use either gas or oil but, in some cases, also use electricity. When a furnace or heater is switched on, it consumes the fuel to produce heat and channel it to the areas in your house. Similarly, when an air conditioner is turned on the electricity is used to lower the temperature of a gas that is encased in a coil into a liquid which cools the air that touches it.
Here are some of the heating and cooling Melbourne systems that can be installed in your house:
- Forced air systems circulates the heat made by the furnace or the cool air from the air conditioner by using a blower fan that is electrically powered through metal ducts and into the rooms. As warm air floods a room, it pushes the cold air into a different set of ducts known as the cold air return system to the furnace to be heated and pumped back into the first set of ducts. This system can be adjusted to increase or decrease the level of air that is circulating in your house. Central air conditioning uses the same process to move cold air into the rooms and bring back the warmer air to be cooled. Although it is an effective method for channeling warm or cool air, it can be noisy and may add to the electric costs as well as gas or fuel bills.
- Gravity systems are based on the rule that hot air expands and rises while cool air sinks and cannot be used to distribute cool air. Thus, the furnace is placed near or below the floor and allows the warm air to rise through the ducts and flow through the house. If the furnace is placed on the main level of the house then the vents letting out the air should always be place higher than the furnace. The cool air that sinks makes its way through the return air ducts to the furnace to be heated and continue the cycle.
- Radiant systems work by warming the walls, floors and ceilings of a room through the use of radiators. Some systems may use panels that use electricity to generate heat but can only be used in areas where electricity is relatively cheap. This system cannot be used for cool air though. Most of these radiant heating systems are built into houses that have a concrete slab as a foundation as the hot pipes used have to be placed underneath it. The pipes heat the concrete and warm the floor. The pipes can become clogged with dirt or deposits and may also bend over time which can lead to problems.
- Split systems are also used and consist of two units. There is a main unit inside that blows the air inside the room and the one outside allows air inside unit to be cooled or heated. They are popular as they have a low initial cost and don’t require much work during heating installation Melbourne. They can easily be installed by a technician in a day or even less but one unit can only heat or cool one unit.
Ducted heating and cooling systems are a great way to tailor the comfort level of your entire home and also allow for more even air distribution in your home and eliminating any cold or hot spots in the house. However, if your house is already built then you may have difficulty installing this type of system especially if there is little space available. It is also an expensive option as compared to split systems and should not be installed if you are looking to heat or cool one or two rooms instead of the entire house.
