Radiator heating: cast iron, aluminum or steel


Theradiator heating represents theheating systemmost widespread; in jargon they are commonly calledradiatorsorheaters. The plants ofradiator heatingthey consist, in the most common form, of onegas boilerwhich supplies hot water used both for sanitary use and as a heat carrier.

The hot water produced by the boiler is introduced into the heating circuit and connected to various radiators through a distributor. At the level ofCentral Distributorthe supply and discharge pipes converge to and from eachradiator. As well as several are available types of boiler for heating, there are several models of radiators, the most common are in cast iron, followed by aluminum and steel.

In the home, we very often try our hand atdo-it-yourself boiler maintenanceprecisely because the water does not circulate properly in theradiators of the systemheating.

Heating with cast iron radiators
THE radiators in cast iron represent the less modern models, they were the first to spread, indeed, once there were only these. THE radiators in cast iron are very heavy, so for installation, if fixed on light walls, special reinforcements must be prepared. Among the disadvantages of theheating with cast iron radiatorswe see that the incoming heat takes longer to cross the thickness of the radiator and diffuse into the environment, the radiator cools just as slowly. The long response times must include, in case of installation of a chronothermostat, switch-on and switch-off times in advance of the times of attendance of the premises A good advantage of theheating with cast iron radiatorslies in their silence: the thickness of the cast iron reduces the subtle noise of the water flowing inside, transmitting the vibrations of the pump.

Heating with aluminum radiators
THEaluminum radiatorsthey are much lighter and less bulky, they are easier to assemble and they are more attractive from an aesthetic point of view. They heat up and cool down more quickly but on the other hand have the defect of transmitting the noises and vibrations produced by the circulating water. THEradiatorsin aluminum are the cheapest, they can also be installed on very light walls even if the enamelling is less resistant than that ofradiatorsin cast iron. Another disadvantage is water control, which is essential for aluminum radiators: if the pH of the water is alkaline, internal corrosion problems may arise.

Heating with steel radiators
This is an excellent middle ground between cast iron and aluminum models, in fact they have intermediate heating and cooling times, corrosion resistance and weight. The only oneneois that unlike thealuminum and cast iron radiators, those in steel are not modular by adding or eliminating individual heating elements. Speaking of prices, they are the ones that cost more on average but also offer interesting design solutions so much that we get to talk aboutheated towel rails.
