What are the benefits?

Correct operation and maintenance, installing heat recovery equipment or replacing an older boiler with a high efficient one, can make significant energy and money savings.

Combustion regulation. A simple adjustment of the burner enables you to control the emissions and the fuel consumption. Fuel savings range between 5-7% of total consumption.

Boiler cleaning. Periodic cleaning of a boiler improves the heat transfer inside it, increasing the useful heat and decreasing the temperature of the waste gases. Every reduction of combustion gases of 20°C means a reduction of approximately 1% in fuel consumption.

Improving boiler insulation. The heat losses through the walls can be reduced by up to 70-80% - that means 1-2% of saved fuel.

Installing an economizer. By using hot combustion gases to warm up the feed water by 5 or 6°C, it is possible to save 1% of fuel. Increasing the temperature of the combustion air by 20°C with the same heat source, leads to fuel savings of about 1%.

Replacing your boiler with a high efficient one. A condensing boiler consumes less fuel than a standard one. In fact, the recovered energy through fumes condensation can be up to 20%. Thus, the combustion efficiency in the condensing boilers can reach even 105-108 %.
