 "Enough energy lands on every section/lot in the country to provide three times the energy needs of a typical home."

DSHH ~ Pricing



Pricing and sizing depends on a few variables:

  1. The size of the home and the areas being warmed.

  2. The options requested

  3. The location, the geotechnical aspects of the sub-surface

  4. Solar Insolation values, how cloudy it is

  5. Types & Severity of Winters

  6. Types & Severity of Summers

  7. Hot Water demand (opt)

Wet-back/Log water heater integration is Free for 2010

Std. Baseline Pricing Materials Pkg.



  • <=170SqM slab area North Island

  • Nominal winters (Min -2c)

  • Nominal Summers (+30c) reasonable solar Insolation

  • Insolation (ie Wellington)

    • Summer 6.27

    • Winter 1.54

    • Nominal clouds

  • DSHH system only

  1. 1M ICF containment

  2. Min 6 Solar ET Panels

Preliminary Baseline costing $16,900 + Delivery & gst

Price will increase with each 50SqM above the baseline of 170SqM ask for pricing on larger homes

Pricing and specifications subject to change without notice.

Colder Climate Baseline Materials package



  • <=170SqM slab area

  • Nominal winters (min. -10c)

  • Nominal Summers (+30c) reasonable solar Insolation

  • Insolation (ie Christchurch)

    • Summer +5.91

    • Winter 1.31

    • Nominal clouds

  • DSHH system only

  1. 1.5M ICF containment

  2. ~8 Solar ET Panels  (Roof real-estate becomes a consideration.)

Preliminary Baseline costing ~$19,800 + Delivery & gst

Area Size increase


170-220SqM slab area is baseline

Each +50SqM above the 170SqM Baseline increases the cost by roughly


This provides:

  • Min 1 Extra ET Solar panel/50SqM

  • Additional slab and heat core pipes and interconnects

  • Added ICF for heat core

  • Added EPS slab insulation

  • Prices for shipping some items can be optimized when shipped with other bulk items such as SuperWindows.

  • System is shipped in two groups:

    • Pipes and rough-in items

    • Main Controller system, solar panels package

  • Payment:

    • 30% prior to first (Piping) package

    • 60% prior to 2nd (Main) package

    • 10% 10 days post delivery of Main package

Other considerations:

  1. Installation, typically arranged and costed by builder

  2. ICF heat core and footing installation

  3. Plumbing & wiring

  4. Insulation of sewer lines etc in the heat core
