In facilities, in addition to limiting, the system activity sequence is also important to achieve energy efficiency. Nowadays, with the general use of VAV (variable volume) systems in commercial complexes, simultaneous heating and cooling and overheating of the primary air are often ignored. Applying boiler restrictions based on outside air temperature, for example when the temperature is above . degrees Celsius, is an effective way to prevent this situation.

The presence of large amounts of accumulation of insoluble solids (TDS) in the boiler water can cause sedimentation and reduce the efficiency of the boiler. Therefore, it is necessary to keep the number of solids below the specified limit. As the total hardness increases, the likelihood of sedimentation and sedimentation increases. Drainage of water, called pot immersion, requires the removal of some of the undissolved solids and keeping the total hardness below the rate at which it precipitates. Low but constant and frequent submergence of high doses but rarely is better because it preserves energy, water, and chemicals. Large boilers with a constant load must be continuously submerged where small amounts of water are constantly drawn from the boiler and fresh compensation water is produced.

There is a significant amount of stored energy inside the engine room boilers. Changing the state of water at a very high temperature from a hot liquid to a vapor releases a lot of energy. (In fact, high-pressure hot water can be converted to steam at atmospheric pressure. This is called flashing.) For example, cubic foot of water will expand by , cubic feet when converted to steam. So if you can trap all the energy from a gallon home hot water blast at degrees Celsius, you have the power to launch a balanced weight car (. tons) to a height of feet with initial acceleration. You will have miles per hour. This height is equivalent to the height of more than a -story building.

Proper water hardening operations are essential to maintain the boiler operating properly. Each water hardening operation must be specifically planned and designed based on the minerals not dissolved in the compensating water, the percentage of distillation return, and the percentage of aeration. Insoluble solids in boiler water and water hardness in small and low-pressure motorhomes should be tested daily and in large and high-pressure motorhomes on an hourly basis. An annual inspection of boilers should include a thorough inspection and testing for signs of fouling or corrosion on surfaces adjacent to the water. The presence of even a thin layer of sediment prevents heat transfer and thereby reduces combustion efficiency. .

Engine room boilers, both in the low pressure and high-pressure categories, must operate in accordance with the instructions of the pressure pipes and boilers of the Mechanical Engineering Association. In low-pressure boilers, the maximum pressure during operation should be psi (pounds per square inch) for steam and psi for hot water. Most installations use low-pressure boilers. High-pressure boilers are designed to operate under pressure limits beyond low-pressure boilers and are commonly used for power plants. The water temperature for hot water boilers is ° C.
