The hot water, usually at 180 F if not pressurized, is produced in the boiler and then pumped through distribution pipes or tubes around the greenhouses. Because only 1 Btu of heat is provided by each pound of water as it cools 1° F, large volumes of water are required with a hot water-based central heating system.

2016/10/27 · An example is the recent engineering design for several different types of large commercial buildings using a 130°F low-temperature hot-water supply with a 20° to 30°F delta T, as opposed to the traditional 180°F water supply. This small design change bumps up overall boiler plant efficiency from percentages in the low 80s to the mid-90s

2019/8/19 · Water and steam are great heat carriers and are not damaging to our environment. The boiling point of water at atmospheric pressure is 100 C or 212 F. By pressurizing the boiling system by giving it an airtight seal, we can actually increase the boiling point. This is how pressure cookers work.

An example would be when a drinking water supply main has a connection to a hot water boiler system that is not protected by an approved and functioning backflow preventer. If pressure in the boiler system increases to where it exceeds the pressure in the water distribution system, backflow from the boiler to the drinking water supply system may occur.

The above system is typical of larger installations at apartment buildings, office buildings, hotels, and other multi-unit dwellings. Multiple boilers supply multiple storage tanks with hot water near 160F. When there is a call for hot water, sensors used with the Heat-Timer ETV 3-way mixing valve, feed temperature information back to the ETV computer control.

Direct fired water heaters are solely dedicated to the job of hot water generation, providing a faster heat up and response time compared with an indirect system which is in fact 'heating water to heat water'. This increases the chance of heat losses in the boiler, and associated pipework between the boiler and calorifier.
