HOW DOES CENTRAL HEATING WORK ?

Central Heating in COILX Company

Your central heating system plays an important role in your home - keeping you supplied with the heat and hot water that make life so much more comfortable. But what systems are available and how do they work?

Advantages of owning a gas system

EFFECTIVE : Warm water central heating systems heat your whole house .

EFFICIENT : Water transfers energy at four times the rate of air making warm water central heating systems so much more efficient than warm air systems.

ECONOMICAL : The initial set up costs are paid back by the long-term cost benefits.

QUIET : The systems are virtually silent.

QUICK : The house can be warm within minutes of the system being turned on regardless of how cold it is outside.

SAFE : A safe option for children and the elderly because there are no naked flames or elements, and for people with respiratory or allergy problems because there is no forced air flow.

CONTROLLABLE : Systems are fully programmable and they can be thermostatically controlled or turned off in rooms that are not being used.

CUSTOMISED : We work out the specific heating requirements of your house to achieve the best heating solution for your home.

FLEXIBILITY : Choose from a range of different heat source and heat distribution combinations to get the best performance and cost benefits for your lifestyle.

Is it cheaper to heat my home with gas or electric?

A gas fuelled central heating system will more than likely be cheaper in the long run. Electric boilers are 100% efficient whereas a good modern gas boiler will see about 95% efficiency. As you might expect, some energy from gas boilers is lost through heat.

What types of central heating systems are available?

Central heating is a way of providing warmth in your home from, as the name suggests, one central source. Central heating systems broadly fall into one of the following types:

  • 'wet systems' involving a boiler/heat exchanger .
  • warm air system
  • storage heaters

How does a wet central heating system work?

With a 'wet system' hot water circulates through a system of pipes that connect to the radiators throughout a house. At the centre of the system, a boiler burns a fuel - or sometimes there is a 'heat exchanger' and this heats the water that feeds the network of pipes. 'Wet systems' are the most popular form of heating system in Egypt .

The pipework may also be connected to a hot water cylinder (tank), which will provide a supply of hot water for bathing and washing.

The same water circulates around your home every single day. Here's how it works:

  1. Natural gas enters your home from a pipe in the street. All the heat that will warm up your home is stored, in chemical form, inside the gas.
  2. The boiler burns the gas to make hot jets that play on a heat exchanger (essentially a copper pipe containing water that bends back and forth several times through the gas jets so it picks up the maximum amount of heat). The heat energy from the gas is transferred to the water.
  3. An electric pump pushes the heated water through the system.
  4. The water flows around a closed loop inside each radiator, entering at one side and leaving at the other. Because each radiator is giving off heat, the water is cooler when it leaves a radiator than it is when it enters. After it's passed through all the radiators, the water has cooled down significantly and has to return to the boiler to pick up more heat. You can see the water is really just a heat-transporting device that picks up heat from the gas in the boiler and drops some of it off at each radiator in turn.
  5. The pump is powerful enough to push the water upstairs through the radiators there.
  6. A thermostat mounted in one room monitors the temperature and switches the boiler off when it's hot enough, switching the boiler back on again when the room gets too cold.
  7. Waste gases from the boiler leave through a small smokestack called a flue and disperse in the air.

What types of central wet systems are available?

  • Radiators system

Despite their name, do not just give off radiant heat, in fact they deliver most of their heat through convection ; air warmed by the radiator naturally rises, and cool air falls relative to it, as a result the warmed air circulates and the 'space' in a room is warmed.

 

  • Under floor  heating systems

Underfloor heating system warms the whole room and stops the need for footwear around the house during those cold winter months! Underfloor heating uses less energy too resulting in lower energy bills. It works via a  series of pipes laid under the floor and as they cover the whole room, it  means that heat can be distributed more evenly than a radiator attached  to one wall.

HOW DOES RADIATOR WORK ?

How Do Radiator Heaters Work?

Radiators draw heat from water or steam and use that heat to warm up surrounding air. By doing this they can effectively be used to heat up a room.

Radiators are made from aluminum because it’s an excellent conductor of heat. Hot water travels through the radiator and the exterior fins naturally heat up over time. As those fins heat up, the surrounding air heats up as well.

Radiators are one of the oldest and most effective ways of heating a home. They’re still used in buildings all over the world today and there are only a few options more effective being relied on. Radiators are still desirable because of their simplicity and their ability to heat a space evenly and comfortably. In order to get the most out of your radiator heating system, or decide if radiators are the right option for you, it’s important to understand how they work.

Radiator Heat Transfer

If you’ve ever looked at a heat radiator you’ll notice that most of them are heavily folded. They have a bunch of creases and are made of some type of metal like cast iron. The creases or folds are designed to increase their surface area so that the metal comes into contact with more air.

Natural Air Circulation

It’s uncommon for a home heating radiator to have any sort of blower because it simply isn’t needed. As the air surrounding the radiator heats up it rises up and out of the way and new cooler air comes in to take its place. A rotational current of air forms around the radiator causing all the air of the room to slowly heat up.
