Boiler Descaling

Boilers are in need of Descaling for numerous reasons.

Some of the main reasons are lack of / or improper chemical treatment, improper boiler “Blowdown”, & neglect of frequent boiler water testing!

Depending on your boiler design & size, chemically descaling your boiler may be the most effective & economical way of cleaning the boiler.

If you are experiencing any concerns, call us for a free evaluation.

Stack Installation

The type of stacks and ductwork used in a boiler’s installation can have a major impact on the boiler’s successful operation and safety of the boiler. It’s important to have a smooth transitional flow to maintain proper boiler draft performance. 

The higher combustion intensity of certain units can become more susceptible to upsets in the flow of flue gas downstream of the furnace. This type of upset or turbulence often feeds back into the combustion chamber, resulting in combustion noise or rumbling. This can easily damage equipment.

Our team can fully evaluate your boiler’s stacks & alleviate any problems you may have.

We deal with single wall stacks, double-wall stacks, insulated & non-insulated stacks – depending on your application.
