Welcome to the Digital Self-Heating HomeTM

 

 

Energy Efficient Homes is please to offer a comprehensive, digitally controlled, reasonably priced, active background solar heating system for homes, offices, and commercial facilities.

_______________________________________

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

 

The DSHH system warms the ground floor of a home through the heating of it's concrete floor slab and in summer when there is excess heat, the heat is stored beneath the slab which is  is physically designed into the foundation of a new home or facility. 

It is designed as Background Heat in the serviced part of the home/office, and helps prevent the living areas from dropping below +18c, once the system storage has reached its optimal holding temp.

Even though this is a background heat, the temperature is still set by the owner. It is not designed as a "Demand" heating system as it uses a huge thermal mass system, which takes time to reach it's set point temperature.

We now offer three new options: Integrated hot water, where hot water gets priority, wetback integration which is currently a free add on, and a hot water heat pump system that heats the hot water extremely fast and with high economy, but also is used as backup heat in the event of more home heat being required.

NEW: The DSHH qualifies for, and EEH plans to introduce a Carbon Tax credit scheme, whereby carbon credits can result in a small cash reimbursement on an ongoing basis, once the carbon tax credit system is established..

It has been many years in development and Patent protection is imminent.

In simple terms, this is how the DSHH system works:

DSHH:    WHAT IS IT?

DSHH:

 Is an Active Solar Heating System

 

  • Captures free year round solar heat, even in winter, then intelligently stores & distributes it as required. It also allows for alternate thermal input from log fireplace wetback boilers , geothermal sources or generators (ask).

  • Huge low-cost thermal mass heat containment storage system under the slab

  • Includes:

    • 1200x1200mm control panel

    • Min 6 (NI) or 8 (SI) evacuated tube solar collectors

    • triple layer oxygen proof, heat transfer pipes

    • <-- Large 100mm (4") graphic digital controller

    • System design and materials package, installed by builder to keep costs down

  • Typical Options:

    • Solar hot water with Min 280L S/S Hot water tank/cyl.

    • Wetback integration: Heats hot water and home

    • Backup hot water heat pump

  • USES:

    • Homes

    • Retirement homes

    • Offices

    • Commercial buildings and warehouses

    • Anywhere a free source of heat energy can assist.

  • WHY?

    • Massive reduction in Carbon footprint

    • Social responsibility

    • OOP, Reduce Out of Pocket expenses for the foreseeable future

    • Health, comfort and happiness of occupants

    • Reduced:

      • Imported energy

      • Balance of payments (if everyone had this)

      • or offset of energy related pollution

    • Being a part of the solution not part of the problem

 

Winter Variables  

The DSHH system uses a huge solar collection system and massive thermal mass heat containment system. Collectors and containment van be adjusted for most environments that have reasonable solar Insolation.

The heat containment storage area is encased under the slab, by an insulated ICF system (like an upside down glass in water). The depth of this system varies with the location and expected winters.

The Solar panels are also resized to add more solar gain in colder area.

The solar panels generate heat even on cold -10c days when the sun is out.

Temperatures below -10c will increase the demand on the system, but still offset much of the homes heating requirements over a given winter

   
Advantages

Uses free solar heat, cost to run is nominal

Carbon footprint is reduced significantly

Other costs of energy are increasing rapidly every year

Health and welfare of residents

Huge improvement in Quality of life

Captures the heat of Summer for winter

Designed as a "Set & Forget" system, with minimum maintenance

We offer energy assessment house reports and can provide an accredited Energy Star Rating for any design starting at less than $1,000.  EEH homes generally rank at the top of the ratings..

 

 

Options

Solar Hot Water: Can be integrated directly or indirectly into the DSHH system with priority

Fireplace Wetback/Boiler heater or other similar heat source can be directly integrated to provide ancillary heat or heat extraction

Hot Water Heat Pump integration for heating and or hot water

Storage: Increased heat core storage

Solar panels: Increased solar capture

PV Electrical power station: Photovoltaic electrical generation. can be Either grid tied (Power meter goes backwards) or battery stand alone. 1kW to 100kW or more limited only by budget and by available space. You can SELL POWER to the grid! As us for more info.

 

Other:

Wind Turbine: Ask for details

Hydro: Small scale hydro power generation from a local reliable stream

 

   
Limitations

The system works best in a thermally efficient home and is not currently designed to be retrofitted to an existing home. Assessments of thermal parameters are available as well as consulting to ascertain the thermal properties of any given design. Pricing on request.

The storage system can possibly take several years to fully "Charge up"

Warmed areas are directly related to the warmed slab

Water: if moving water is found during footing excavation, the entire cavity must be removed, sealed as per DSHH instructions, lightly insulated, then refilled with compaction.
