Sustainable Heating for Hybrid Home

Project: Nemenhah Perma-Village Model

Posted by Chief Phillip 'Cloudpiler' Landis over 13 years ago

Retrofitting a recycled Mobile Home with sustainable heating in the floor.

We intend to leave five of our ten acres completely in wilderness forest.  One thing that struck me about the Oak and Hickory forest is that, for ever acre of second growth you have there will be .8 cords of limbs and branches that fall each year.  This windfall is surplus energy and can be utilized to heat four homes through winter in this region.  Limbs and branches are also ideal fuel for use in a Rocket Stove.

One of our projects this Spring will be construction of a Rocket Stove that will serve as a model for Enerty Function Stacking.  The design includes two Down-Draft Rockets to provide instant heat for a cook surface, water heater for in-floor heating, and for thermal mass heating as well. 

Using an old water heater placed so that the secondary combustion takes place below and around the sides, water will be heated to create a constant syphon into the in-floor heating system.  The water pipes will be placed right up against the subfloor and a two-inch sheet of insulation will be attached below the pipes.  A vapor barrier is attached below the insulation.  This arrangement will directt the heat from the pipes upward into the floor, rather than downward into the ground.

One of the things that makes this plan feasible in a Mobile Home retrofit is that the home is set on pillars, providing three feet of crawl space.  This give excellent access to the underside of the floor.  The old insulation will be removed and transferred to the attic.  Then the subfloor is exposed and ready for the pipe and foamboard to be attached.

A new foundation was laid so that the Adobe Block skin has a good, solid footing, and this also provides a more stable thermal environment under the house.  A second vapor barrier is placed on the ground below the house.

Function stacking insures that energy surplus, such as the solar energy lost in the limbs and branches of our forest, is used to create a sustainably comfortable built environment.  The ash and char that is created by the system (admitedly little) is returned into the vineyard where a higher soil pH is desired.

Legend of Badges

Note: The various badges displayed in people profiles are largely honesty-based self-proclamations by the individuals themselves. There are reporting functions users can use if they know of blatant misrepresentation (for both people and projects). Legitimacy, competency and reputation for all people and projects can be evidenced and/or developed through their providing regular updates on permaculture work they’re involved in, before/after photographs, etc. A spirit of objective nurturing of both people and projects through knowledge/encouragement/inspiration/resource sharing is the aim of the Worldwide Permaculture Network.



A member is a permaculturist who has never taken a PDC course. These cannot become PDC teachers. Members may be novice or highly experienced permaculturists or anywhere in between. Watch their updates for evaluation.

Male memberFemale member

Permaculture Matchmaker

One of these badges will show if you select your gender and the "I'm single, looking for a permaculture partner" option in your profile.



People who claim to have taken a Permaculture Design Certificate (PDC) course somewhere in the world.


PDC Verified

People who have entered an email address for the teacher of their PDC course, and have had their PDC status verified by that teacher. Watch their updates for evaluation.



People who’ve taken a Permaculture Research Institute PDC somewhere in the world.


PDC Teacher

People who claim to teach some version of PDC somewhere in the world.


PRI Teacher

With the exception of the ‘Member’ who has never taken a PDC, all of the above can apply to become a PRI PDC Teacher. PRI PDC Teachers are those who the PRI recognise, through a vetting board, as determined and competent to teach the full 72-hour course as developed by Permaculture founder Bill Mollison – covering all the topics of The Designers’ Manual as well as possible (i.e. not cherry picking only aspects the teacher feels most interested or competent in). Such teachers also commit to focussing on the design science, and not including subjective spiritual/metaphysical elements. The reason these items are not included in the PDC curriculum is because they are “belief” based. Permaculture Design education concerns itself with teaching good design based on strategies and techniques which are scientifically provable.

PRI PDC Teachers may be given teaching and/or consultancy offerings as they become available as the network grows.


Aid Worker

The individual with this badge is indicating they are, have, or would like to be involved in permaculture aid work. As such, the individual may or may not have permaculture aid worker experience. Watch their updates for evaluation.



The individual with this badge is indicating they are, have, or would like to do paid permaculture design consultancy work. As such, the individual may or may not have permaculture consultancy experience. Watch their updates for evaluation.


Community Project

Community projects are projects that help develop sustainable community interaction and increase localised resiliency.
