Because a central heating model does not have any electrons travelling through wires but have water. If a wire broke in a electric circuit , then if you're not going to turn off the circuit you would get electrecuted. In a central heating system, if it would break water will leak and nothing will hurt you or anything and you won't get electrecuted.
How is the central heating model not like an electric circuit?
Space heaters are very much designed to live up to their name. Electric space heaters mean that almost everybody in the UK has access to warmth without expensive central heating.
Coal was a very important heating factor in the early days, sadly, coal has now been replaced by gas/electric central heating, which is a probably a lot cleaner, safer and easier for modern day living.
You will get a short circuit if two uninsulated parts of the supply conductors, touch each other. You can also get a short circuit if the "hot" supply conductor touches any grounded metallic part of the system.
the element has a open in it !
How is the central heating model not like an electric circuit?
The cheapest option between electric, radiators and central heating is Gas Central Heating. The reason that gas is cheaper than electric is because electricity costs 4-6 times more than gas.
Examples are the tungsten element inside a light bulb, and the heating element bars of an electric fire.
There are many places where one could find information on how to install electric central heating. There are many places where one could search for advice like WikiHow. One could also contact a home heating professional.
The service performed by central heating itself is heating a home or building. A central heating service or company can provide repairs or installation of central heating units.
I = P/EI = 5000/240I = 20.83 A20.83 A of current will flow in the circuit.
Hi, Electric heating it self is more efficient, however the way the electric is produced is not.typically for every 1kW of power you put into to an electric heater you get 1kW out, but it to produce the electric it takes 3kW of coal ect, to produce 1kW of electric. A gas boiler can be 98% efficient so overall better.So unless you have way of producing electric yourself or have an efficient supplier, go for gas.Hope this helps.gas.

Electric heating is widely used; evidently it is feasible.
This type of a heating system is known as central heating.
Rather than have a coal, gas or electric fire heating one room, central heating is one boiler (gas or electric) heating the whole house. This is done by pumping hot water through pipes that feed several radiators installed in each room and hall way. A thermostat in the hall (for instance) allows the temperature to be controlled overall, with a regulating valve on each radiator for separate room control.
A central heating system is one that heats the whole house from one location. Natural or bottled gas and heating oil are widely used as fuel. Electric heat pumps are common in milder climates. Coal used to be used but is not common in the US nowadays.
