Hot water heating systems (Figure below) transport heat by circulating heated water to a designated area. Heat is released from the water as it flows through the heating unit (coil, terminal).
After heat is released, the water returns to the boiler to be reheated and recirculated. Low temperature hot water boilers are ≤ 250°F. High temperature hot water boilers are >250°F.
ADVANTAGES OF HOT WATER HEATING OVER STEAM HEATING
Hot water heating systems produce heat more consistently than steam heating systems. The water in a hot water heating system remains in the lines at all times.
The water in the heating unit lines heats and cools slowly, resulting in an even rate of heat production. When pressure is lost in the steam heating system, steam leaves the heating units resulting in a more rapid loss of heat than in a hot water heating system.
In addition, the steam heating system has a longer recovery time in producing heat after the boiler is shut down.
Boilers are used in both hot water heating systems and steam heating systems. The hot water heating systems most often encountered in HVAC work will be low temperature systems with boiler water temperatures generally in the range of 170-200 degrees Fahrenheit.
Most of the steam heating systems will use low pressure steam, operating at 15 psig (30 psia, and 250°F). There are a great many types and classifications of boilers. Boilers can be classified by size, construction, appearance, original usage, and fuel used.
Fossil-fuel boilers will be either natural gas-fired, liquid petroleum (LP) gas-fired, or oil-fired. Some boilers are set up so that the operating fuel can be switched to natural gas, LP gas or oil, depending on the fuel price and availability.
The construction of boilers remains basically the same whether they’re water boilers or steam boilers. However, water or steam boilers are divided by their internal construction into fire tube or water tube boilers.
After heat is released, the water returns to the boiler to be reheated and recirculated. Low temperature hot water boilers are ≤ 250°F. High temperature hot water boilers are >250°F.

I had no idea that boilers could help get water up to 200 degrees. I think it's so important to have hot water in your home. It helps with cleaning, cooking, and basic living. I really don't know what I would do without it! http://www.kenhaleplumbing.com.au/services

I think the energy use to produce hot water instead of steam will also be very good step towards energy efficient systems.

Hot water heating is more efficient because it's easier to control. Steam will take the path of least resistance and sometimes you'll find in older steam applications that there are a lot of hot and cold spots. It's hard to balance steam. Whereas with hot water, we're able to direct the water flow pretty easily to the areas where we want the heat and hot water. Hydronics is the way of the future.
Thanks for sharing valuable article.
