Open Source Hydronic System

Basics

• OSE's Open Source, Modular Hydronic System in use by OBI
• Currently is focused only on heating (Double check this)
• Uses the Hydronic Stove as a heat source
  • Is solar thermal water panels also included yet (need to look/ask around)

On Cooling Addition

• Energy . gov page on hydronic cooling
• a hpacmag . com article on this

On Geothermal Heat Pump integration

• Complex, but may be doable
• See Geothermal Heat Pump

Combining the system with a hot water storage tank

• All heat (from the Hydronic Stove, a solar thermal panel, waste heat, etc) is "fed in" to a tank of the working fluid
• This can then be used directly, or be used to heat air, water, or another fluid
• Also may allow for some Thermal Energy Storage
• Heat exchangers, and most likely custom tanks would make this quite complex
  • It may help with modularity, compact-ness, and efficiency

Open Source Hydronic Design

edit

Hydronics Install Prior to Stove Connection

Simple hydronic circuit for both 1/2" in-floor lines (1000 feet in a single zone) + a wall radiator outlet (3/4" tube) using oxygen barrier PEX. Parts cost of $500 approximately for the hydraulics control panel - $100 pump, $100 divider valve, fittings, gauges.

Prior to In-Floor Tubing Connection

In-Ground Heat Tubing Install

Prepare to Put in Wood Floor

Floor will be stained 1"x4" lumber on 2"x4" rails

Product!

Warm feet.

Industry Standards

• $4600 - 20 year warranty - Glenwood 7020 - [1]
• $3600 - 5 year warranty - says Gasifier type - water heat exchange medium - Slovak import - [2]
• $3500 - Biasi - [3] - Remaining exhaust heat is given-up in a wide finned, self-cleaning passageway before exiting the boiler.
