The current trend in radiant heating is towards underfloor heating, where radiator warm water is circulated under the entire floor of each room in a building. A network of pipes, tubing or heating cables is buried in the floor, and a gentle heat rises into the room. Because of the large area of this type of radiator, the floor only needs to be heated a few degrees above the desired room temperature, and as a result, convection is almost non-existent. These systems are reputed to have a high level of comfort, but are generally difficult to install into existing buildings. For best results, a floor covering that conducts heat well (such as tiles) should be used.
The hypocaust was a Roman heating system using a similar principle of operation.
The towel warmer is elegance European style designed with high thermal conductivity.
2. It is long lifespan, fast weld, anti-oxidize and never fade in color.
3. The heater is made of stainless steel with different kinds of shape, such as D shape, round shape, square shape and so on.
4. The towel radiator’s surface is plastic spray or chrome-plated. Also we can produce electric towel warmer .
5. The products are widely used in bathroom, living room and bedroom.

A more recent type of heater used in homes is the fan assisted radiator. It contains a heat exchanger fed by hot water from the heating system. A thermostatic switch senses the heat and energises an electric fan which blows air over the heat exchanger.
Advantages of this type of heater are its small size and even distribution of heat around the room. Disadvantages are the noise produced by the fan, and the need for an electricity supply.
A conventional hot-water radiator consists of a sealed hollow metal container, usually flat in shape. Hot water enters at the top of the radiator by way of pressure, from a pump elsewhere in the building, or by convection.
As it gives out heat the hot water cools and sinks to the bottom of the radiator and is forced out of a pipe at the other end. The pipe either has a large surface area or attached fins to increase its surface area and therefore contact with surrounding air. The air near a radiator is then heated and produces a convection current in the room drawing in cold air to heat.
If set up improperly, radiators, and their supply and return pipes, can make loud banging noises like someone hammering on the pipes. This is due to either the pipes rubbing on surrounding surfaces while expanding and contracting due to heat changes or to sudden fluctuations of the supplied water pressure. Proper mounting of the radiators and supply pipes will reduce expansion noises, while upward-mounted stub ends with a trapped bubble of air (not interfering with flow, as would an un-bled radiator) will provide a cushion against pressure fluctuations, an anti-hammer device.
Stereotypical cast iron radiators (as pictured) are no longer common in new construction, replaced mostly with copper pipes which have aluminum fins to increase their surface area. In the U.K., modern domestic radiators tend to be of sheet steel construction (often with steel fins), though copper/aluminium is often found in industrial Air Handling System heat exchangers.
The radiator was invented in 1855 by Franz SanGalli. He was the first to produce a system of central heating and patented his invention in Germany and the US.
There are many designs and varieties of radiators, from conventional to modern style. Radiators are sometimes seen as an art form, much like sculpture.
All “radiant” (ie. heat radiates from hot water) systems need to be bled, or purged of air, on occasion.
If there is air (or other gases such as Hydrogen) trapped inside the radiator, then the water cannot rise to the top, and only the bottom area gets hot. A bleed screw near the top of the radiator allows the trapped air to be ‘bled’ from the system, and thus restore correct operation. Often radiators located on upper floors will accumulate more air than ones on lower floors as the air will tend to rise to the topmost point in the system. These may have to be bled more often. Usually radiators are bled once or twice per season, or as needed. Another reason to exclude air is to minimise corrosion of the steel pressed radiators. Note that most central heating systems need a corrosion inhibitor added into the circulating hot water, so that the production of Hydrogen is minimised. This is created in untreated systems, by the action of the hot water on the iron in the absence of air (stripping off the oxygen atom to leave hydrogen as H2 when iron oxide is created). Note that if air is getting into the radiators frequently, this may be the sign of a leak somewhere, such as a dripping valve, or loose joint.
