This technique uses vertical drilling to capture geothermal energy for heating with a minimal surface area. Sensors made of polyethylene tubing are inserted into wells spaced 5-10 meters apart near or under a house. The wells are then sealed with a gravel/sand and bentonite mixture to conduct heat and protect against landslides. A water/glycol mixture circulates through the closed system of sensors to extract heat from the natural underground temperature of 10°C. A standard water/water heat pump is used along with a floor heating or low-temperature central heating system inside, providing excellent performance coefficients of 4 or more due to the constant underground temperature.

State of the Art Review of Unvented Sloped Wood-Framed Roofs in Cold ClimatesRDH Building Science
Typical residential house construction in North America has long had vented attics above living space with the insulation and air control layer at the ceiling plane of the living space. Except for documented wintertime condensation issues in cold climates, such vented attics generally perform quite well, provided that they are ventilated adequately and air leakage from the interior is prevented. However, architects and designers are moving away from empty attics by using the attic space as conditioned storage or bonus rooms, or by designing larger interior volumes with cathedral ceilings. The practical challenges of ventilating cathedralized attics and cathedral ceilings have been significant, both because of increased geometrical complexity and because of the number of penetrations typically required for services.
Spray foam has been used successfully in tens of thousands of unvented roof assemblies throughout North America but some concerns remain in the building industry that these assemblies are inferior to ventilated roof assemblies. The National Building Code of Canada, in particular, makes it difficult for designers to use unvented roof assemblies, even using designs that are approved in similar building codes in the United States and have been proven to be durable, high-performing options. Over the past decade, the authors have been directly involved with studies of both 0.5 pcf (8 kg/m3) open cell spray foam, and 2.0 pcf (32 kg/m3) closed cell spray foam in unvented roof assemblies in various climates with continuous monitoring of temperature and moisture conditions. This paper provides a literature review of research that has been conducted on wood-framed sloped unvented roof assemblies, but will focus on results from a field monitoring study of sloped unvented wood roofs in partnership with the University of Waterloo, as well as a field survey that opened roofs and removed samples from aged unvented roof assemblies.

1. Technique
This technique is the most suitable for an area with limited
space. It is enough to dispose the minimum surface to achieve
the operations of vertical drilling.
The capturing of the calories with vertical detectors requires
drillings spaced min. 5-10 m, realized close to the house or
under it before its construction. Geothermal sensors made of
polyethylene tubings in U-shaped are introduced in the wells.
After the installation of the sensors the holes are sealed with a
mixture of gravel or fine vibrated sand and 'Bentonite', chose to
assure a good heat conduction and a good protection against
possible landslides, root attacks, …
Then the principle is the one of a WATER/WATER heat pump with
glycol water which circulates in a closed circuit in the senors to
fetch the calories present in the natural cellar. The
WATER/WATER heat-pump is a standard equipment, which
generates the best performance coefficient, the house-side
network is a classic installation of the type of floor heating or of
central low-temperature heating; which gives a quite simple
installation beside the drillings which demands a precise effort
and study.
The yields or performance coefficients are excellent (4 and
more) because, from a depth of 12 m, the ground has a relatively
constant temperature of 10°C, in any season, which corresponds
to the optimal conditions to use the ground as a resource of
heat.
