Säätötuli hot water biomass boiler

Säätötuli hot water biomass boiler

ASME hot water biomass boiler manufactured in Canada

Säätötuli’s hot water biomass boiler can be used as any standard hydronic boiler. It can be connected to a hydronic heating system inside a building, or to a heat network covering several buildings, or even a municipal district heating network.

Output ranges from 545,942 BTU/hr (160 kW) up to 5,118,213 BTU/hr (1.5MW). Our hydronic boilers, as any pressure vessel, have a Canadian Registration Number (CRN). They are manufactured to ASME section IV by our partner ProMétal Plus in Deschambault, QC.

Säätötuli boilers are especially designed to be connected to a Säätötuli burner and Säätötuli biomass fuel silo and conveyor. You can see the different equipment we can offer on our page about the biomass silo systems.

The boilers are fitted with an 18-inch access door, making cleaning and servicing easy and allowing to check the aspect of your flame easily.

Säätötuli’s ASME hot water biomass boilers can also be preinstalled on a skid or inside a containerised biomass heating plant.

Hydronic biomass heating with Säätötuli hot water biomass boiler

Vertical heat-exchanger

Säätötuli’s hot water biomass boiler is equipped with a vertical tube heat-exchanger. The advantage of a vertical exchanger for biomass boilers is that the flying ashes will move downwards with gravity instead of getting stuck in the exchanger. This reduces considerably the need for cleaning.

The hot water boiler can be equipped with an optional automated boiler cleaning system. This system is made with steel springs that will vibrate and avoid the ashes to fix themselves to the fire tubes. When using wood pellets or clean woodchips with the automated boiler cleaning system, the hydronic boiler may in certain cases need as few as a single annual cleaning of the heat exchanger.
