Jun 08, 2009 · The other primary option for using a heating system to produce hot water is to install an "indirect" or "indirect-fired" water heater. This is a separate insulated water tank that is heated using hot water from the gas- or oil-fired boiler. The indirect tank is usually plumbed to be a separate "zone" on the heating system.
Read moreFeb 17, 2022 · The boiler or furnace only produces enough heat to satisfy that demand no matter what it is. This saves energy, as less heat is sent outdoors with the exhaust gas when the burner is on low. Perhaps the most basic heating system you can install is one that just uses electricity. Simple baseboard radiators or portable ones can be used for heating.
Read moreThe boiler is a closed vessel, where the water is stored. Hot gases are formed by burning fuel in the furnace. These gases are made to come in contact with the water vessel, the point where the heat transfer takes place between the steam and water. Thus, the boiler's basic principle is to convert water into steam with heat energy.

Read moreMaintaining the pH of boiler water in the range of 9–11 decreases the rate of corrosion; 9.2 to 9.8 is ideal. In low-pressure steam or hot water heating systems, nitrite or chromate provides a protective film on metal surfaces. Filming amines provide a physical barrier to protect metal from corrosion. They are effective in the pH range of 5.5

Read moreWater-tube boilers have a limited water surface area in the steam drum, relative to the evaporation rate. This results in very high steam release rates per unit of water area, and turbulence. Water-tube boilers tend to be higher rated, perhaps over 1 000 tonnes/h of steam. This means that even a small percentage blowdown can represent a high
