The historic Ladd Hall in Waterbury, VT has gone through a huge makeover. The building was sitting vacant since August 2011, when Tropical Storm Irene hit and flooded the basement. The original building was bult in the 1890’s with a wing added in the 1950’s to house nurses working at the state hospital. The building was then later used for offices for the state.
The original front brick building was converted into 2 3-bedroom apartments and a one bedroom apartment on the third floor. The 1950’s addition was totally demolished and replaced with new construction to house 23 more apartments (twelve1-bedroom and eleven 2-bedroom). The new wing is where the new heating system is located and is built to high energy efficient standards. The total square footage is 28,000 Sq. Ft. Building owned and operated by Downstreet Housing and Community Developement located in Barre, VT.

The new heating system comprises of two 350,000 Btu/hr Fröling P4 pellet boilers with 900 gallons of heat storage. Heat storage allows allows efficient heating of Domestic Hot Water year-round and efficient boiler. The building has NO fossil fuel back-up boiler. The pellet boilers are estimated to offset approximately 10,000 gallons of heating oil annually. The boilers are connected to a 20 ton interior pellet store room. Each boiler has it’s own suction auger delivery device.
Heating System was designed by Trevor Parson, Engineering Services of Vermont, and Sunwood Biomass. Installed and manitained by SunWood Biomass, Waitsfield, VT. 802-583-9300

The first Fröling Turbomat 500 (TM 500) has arrived in the USA! The TM 500 is a 1.7 mm Btu/hr. boiler capable of burning wood chips up to 45% moisture content or wood pellets. The boiler weighs over 18,000 pounds, in large part due to its heavily bricked firebox, which is necessary for wetter wood chips. The TM 500 uses a unique vertical heat exchanger that separates and drops out ash rather than allowing for ash to sit on horizontal heat exchanger surfaces. The TM 500 is designed to run 24 hours per day with no shutdowns for cleaning or re-fueling. The special alloy walking grate system needs no hoeing or scraping. The new TM 500 replaces another wood pellet boiler installed at Peoples Academy in 1982. The existing wood pellet boiler burned approximately 130 tons of wood pellets/year. The fuel feeding system is very simple for this installation. It consists of an exterior silo connected by flex auger to a surge bin above the boiler's feed auger.
The TM 500 will be replaced in the off shoulder seasons by a Fröling P4 100 pellet boiler when heat demand is lower. The P4 100 feeds itself by vacuum from the same silo that supplies the TM 500.
Both pellet boilers were sold and installed by Sunwood Biomass of Waitsfield, VT (802) 583-9300, www.sunwoodbiomass.com.
Below are some photos showing the assembly process.
The heat exchanger and the combustion chamber are joined together at the heat exchanger flange.
Neccessary components are installed before insulation and jacket assembly.
Insulation batts are installed.
Jacket frame assembled.
Draft fan and stoker feed components assembled.
Flue gas recirculation, ash containers, door switches, air actuators, electical panel, etc installed.
Inside the combustion chamber (bottom). Here is good view of the moving grate and the fireclay bricks. Amazingly, all of this was asembled at the factory before it was shipped (approx. dimensions 3’x7’.
Combustion chamber (top).
The combustion chamber is almost large enough to lose someone.
Below, is a cross section view of the combustion chamber.
A Fröling P4 80/100 boiler (350,000 Btu/hr) was also installed for use during the shoulder heating season. This TM 500 will be burning wood pellets. An intermediate surge bin (pellet hopper) was installed to bridge between the silo’s auger and the the boiler’s stoker fuel auger system.

Boiler: Fröling FHG 20/30 (100,000Btu/hr) wood boiler. Gas back-up boiler.
Thermal Storage: Custom built 600 gallon open atsmosperic tank with heat exchangers.
Domestic Hot Water: Solar Thermal with 120 gallon Indirect Water Heater.
Sold and Installed By: Sun Energy 1599 270th Avenue, Mora, MN 55051 www.sunenergyusa.com
Customer has completed his third heating season and is thrilled with his system. He is estimating a yearly savings of over $1,500.00. His yearly fuel consumption is 6-7 full cords of wood. The installation is located in a urban area which shows that a wood boiler does not have to be installed in the country.

Installed By: Jackman’s Inc. 32 Pine Street, Bristol, VT 05443 www.jackmansinc.com
The system is installed in an 1,700 sq. ft. home with radiant floor heat on the main floor and traditional baseboard on the second floor. The customer replaced the old oil boiler with the wood system and a new efficient gas boiler for back-up. The two tanks were insulated by constructing an insulated box around the tanks. This is very easy to do and can be done by the homeowner. This installation has R-42 in the walls and R-48 in the ceiling. One thing to remember, the tank sensors must be insulated to the tank. This enables them to read tank temperature and not the air temperature around the tanks.
The customer is amazed at how easy the boiler is to use and start. They maintain over 30 wooded acres, so plenty of wood fuel to sustain them into the future.
Two 300 gallon tanks shown before the insulation was installed. Tarm Biomass can also supply all the neccessary fittings for the tank’s manifolds. They are piped in parallel (reverse return), so water flows evenly between both tanks. The two 300 gallon tanks act as one single 600 gallon tank.
