The Temperature in Your Boiler and the Dangers of Overheating

The average setting for a gas-powered hot water boiler is 180°F. This provides the appropriate level needed for most cold weather temperatures. If you can raise the temperature manually, do not set it any higher than 210°F (which is often the limit), and try to remain down at 190°F if you need the extra heat.

Water Level & Alarm Float Switches for Boilers - SMD Fluid

Boilers are relatively simple machines that can be used for a variety of purposes: water heating, central heating in homes and other buildings, to generate steam for power, sterilization, cooking, and more. Composed in the most basic sense of a metal pressure vessel that contains the fluid to be boiled, a source of energy to heat it, and some

Boiler feed water - Lenntech

The boiler receives the feed water, which consists of varying proportion of recovered condensed water (return water) and fresh water, which has been purified in varying degrees (make up water). The make-up water is usually natural water either in its raw state, or treated by some process before use.

How to Destroy a Boiler -- Part 1

Boilers rely on the water to protect the steel boiler tubes from the temperatures in the furnace which greatly exceed the melting point of the tube material. A buildup of deposits inside the tubes will produce an insulating layer which inhibits the ability of the water to remove the heat from the tube.

What is the safe pressure for a hot-water-heating system?

Most residential hot water heating systems run at 5-psi more than the pressure required to raise the water from the fill valve to the highest point in the system. In my Cape Cod house, with the boiler on the floor of my garage, the pressure gauge reads between 12- and 15-psi (the dial is too small to read more accurately than that).

Steam Boiler Water Level Control | The Industrial Steam

Jan 30, 2018 · Anyone who has ever boiled a pot of water for cooking knows how this process works. Making steam continuously, however, is a little more complicated. An important variable to measure and control in a continuous boiler is the level of water in the steam drum (the upper vessel in a water-tube boiler).

Boiler: Valve to Automaticly Add Water | Terry Love Plumbing

If the WATER LEVEL SWITCH on the boiler failed. Then the valve will not get the signal to close when the water level is sufficiently high. Water will continue to fill, non stop. I have had my boiler's water level switch stuck years ago, when I first bought my house. I was manually filling the boiler so I just shut the valve, with my hand.
