Most of our gasification boilers need the same basic accessories.

Typically, this is what we recommend.

The EKO-25, EKO-40, Tarm-30, and the Tarm-40 would each be plumbed
with a primary loop of 1-1/4" pipe.

The EKO-60 and Tarm-60 should be plumbed with 1-1/2" pipe.
The EKO-80 should be plumbed with 2" primary pipe.

The EKO needs:

1 Pressure relief valve, 30#
1 Pressure & Temperature Gauge, the boiler has an internal gauge but this helps with flow temps.
1 Air Separator, usually a Taco Vortec or Spiro-vent.
1 Expansion Tank, (typically a #30 for the smaller boilers, #60 for the larger boilers.
1 Loading Valve, either a Termovar or a Danfoss.
1 Pump for the Primary loop (additional pumps may be needed for other zones).
1 Pump flanges with purge drains for each pump.
1 Water Prep Solution 102, to clean and prep the boiler.
1 Water trreatment 101, to protect the water in the boiler.

The Tarm needs all the same things except it comes with the Pressure relief valve already.

The Tarm, EKO, and BioMax all will perform better and more efficiently with a Thermal Water Storage System. See the related website to learn more.
