why do we need two steam boilers for hospitals

New Boiler Regulations 2018: What Do They Mean?

Boilers with this technology can reuse heat from the boiler that would usually be wasted. Some studies claim that these boilers can output the same amount of heat while using 4% less gas, making the boiler even more energy efficient. Many new boilers will already have this technology. However, it's worth asking your installer to check.

With a two-pipe system, the steam is supplied in one pipe and the condensate returned by gravity to the boiler by another. The radiators do not have an air-vent valve, instead they are equipped with steam traps that allows the air bound in the radiator and condensate to flow in the return pipe but closes on steam contact. (A two-pipe steam

My Boiler Pressure is Too High? A 24|7 Home Rescue Guide

We often say that a boiler's pressure should be at around one bar, but this is only when your central heating is turned off and you are not running any hot water. When your boiler starts heating up water, the water expands (think of how steam takes up more space than water), which causes the pressure gauge to jump up.
