Protection Considerations for Wood Gasification Boilers

Enroll in this free, 58-minute lecture and learn about the protection of wood gasification boilers.

Enroll today and learn more about the protection of boilers against low entering water temperature and against overheating during power failures.

I will discuss the dewpoint of exhaust products, how to protect wood-fired boilers against low water temperatures through thermostatic bypass valves, loading […]

Sizing a Pellet-Fueled Boiler

Sizing a Pellet-Fueled Boiler
Bigger is NOT better
There are several types of boilers that can burn wood-based fuels. They include 2- stage wood-gasification boilers, wood chip boilers, and pellet-fueled boilers. Of these, pellet-fuel boilers come closest to mimicking the fully automatic operation of oil and gas- fired boilers. Modern pellet boilers can automatically load their fuel, […]

Wood Gasification Boilers: Circulation, Power Interruption & Pump Acceleration

On the Hydronic-Based Biomass Heating Systems Discussion Board…
Why we don’t use the UPS to drive the main circulator to continue operations in case of power interruption? What determines when wood gasification boilers begin to circulate? Do variable speed pumps allow us to control the rate at which the pump accelerates? John Siegenthaler investigates…

Student 1:
If we use a […]

Floor Joist Heating Issues: Siegenthaler Suggests…

On the Hydronic Based Biomass Heating Systems Discussion Board, John Siegenthaler answers student questions…
How do you deal with cold floors over unheated or outdoor spaces? If radiant heat (typically used for walls/ceilings) for joisted floors is properly designed and installed, can it be efficient, effective and comfortable?

Student 1: I would like you to elaborate on the floor joist heating.

I […]
