Electric Heating: What is it? (Types of Electrical Heating

Oct 07, 2016 · In the direct resistance heating, the current flows directly through the substance to be heated. The substance which to be heated in an electric heating system is called charge. As here the charge itself provides the path for passing current and heat gets produced in the charge itself, the efficiency of the system is quite high.

How to run a hot-water zone off a steam boiler - Heating Help

Jun 18, 2014 · Heating professionals have been doing this for years in areas such as New York City where there's still a bodacious amount of steam heat. The principle is the same, regardless of the width of the pipe. the water in the zone will bypass the boiler because it's easier to go through the bypass than it is to go through the boiler. That's

Safety valve - Wikipedia

A safety valve is a valve that acts as a fail-safe.An example of safety valve is a pressure relief valve (PRV), which automatically releases a substance from a boiler, pressure vessel, or other system, when the pressure or temperature exceeds preset limits. Pilot-operated relief valves are a specialized type of pressure safety valve. A leak tight, lower cost, single emergency use option would

Forced-air - Wikipedia

A forced-air central heating system is one which uses air as its heat transfer medium. These systems rely on ductwork, vents, and plenums as means of air distribution, separate from the actual heating and air conditioning systems. The return plenum carries the air from several large return grills (vents) to a central air handler for re-heating. The supply plenum directs air from the central
