Insulation of boilers is necessary to protect people against contact with hot surfaces and to ensure an acceptable working temperature in the boiler room. Insulation of boilers is a very efficient way to keep water hotter for longer, especially if the equipment is exposed to cold conditions in winter.
It is an improvement for very old boilers that cannot be substituted for technical and economic reasons
Avoid heat loss and optimize the efficiency of the boiler
Lower water temperature setting
It must go with other measures to achieve significant energy savings
Initial investment: low. 1-3% economic saving. Payback in 1.5 years.
