Commercial Solar Heating Applications



Hydronic Heating

Heating Applications

Any facility that uses copious quantities of heating or hot water, can benefit for the DSH System. Of necessity  the more heat required in balance, the larger the area required for solar panels. Any heating application with slab flooring are perfect applications for solar heating.

Applications requiring heat from 20c (68f) to 200c (392f) are commercially viable.


Besides the obvious, any commercial requirement for large quantities of hot water are also perfect scenarios for the DSH system.

  • Hotels, Motels,
  • Hospitals,
  • Retirement centers
  • Laundries,
  • Car Washes,
  • Recreation centers,
  • Pools,
  • Military billeting
  • Retirement Centers

These are just few of the common  facilities where large quantities of hot water are used daily.

Inter-seasonal Storage

Heat Transfer moves surplus heat from summer sunshine, and stores it in Thermal heat core, This is typically in ground and transfers stored heat on demand, to heat buildings in winter or during dark times.

Stored heat in this case is only used for backup heating, not hot water.

The DSH storage system is based on low cost Geo-storage and is installed under the insulated slab of the building, requiring most systems to be installed during the foundation construction period. Heat cores are capable of storing multiple TWt of energy, scalable with the size of the building. Without a massive solar storage system, summer heat would need to be vented instead of stored, a complete waste of usable energy.

Hydronic heating is a quiet, dust free, draft free heating system that optimizes stratified heating to its beast advantage. Using free solar energy for much of the heating, it provides high  economy with low/no  GHG/carbon emissions which can be a potential marketing Bonanza


Backup Heating

In extremely cold environs such as Canada, reliable heating is essential, all DSH systems will integrate an approved backup boiler or heat pump as required. The type and size specified will depend on local circumstances, but will automatically engage as required for comfort.

The DSH system is also capable of integrating open flame heating appliances such as biomass boilers, Pellet boilers, wood burning boiler systems, and waste heat capture such as refrigeration or flue.

Long Term Savings

Long term Savings: The DSH system is expected to reduce yearly heating costs by >50%. as compared to a traditional forced air systems., This means that the higher initial cost of solar hydronic heating can be easily recouped by building owners and operators. And, during that period the carbon emissions are reduced by 100% of the thermal offset.

Saving the Operational Expenses  by way of cost of energy, all the WHILE reducing your GHG carbon footprint is: a rare win-win.

Optimally low caloric hydronic heat is delivered to an insulated slab floor, where due to high thermal mass, heat is retained over long periods. As a rule slab floors temperatures are limited to less than <=30c for comfort.

Examples where DSH solar heating can be financially beneficial as well as corporately responsible with respect to GHG and carbon reductions:

  • Warehouses
  • Retirement & Nursing homes
  • Shopping malls
  • Hospitals & Doctors offices
  • Offices and workspaces
  • Garages & Parking
  • Footpath & driveway melting
  • Schools & Gymnasiums
  • Prisons and corrections
  • Greenhouses
  • Airports & Railways stations
  • Big Box Buildings

 All  “Heating applications” include/require  an approved backup heating system by code.


Reduce the energy costs of snow melt for roofs, sidewalks and driveways and parking lots


Retrofitting, while much more difficult, it is possible in many locations, where a storage system can be engineered adjacently or by some other means, and hydronic heating can be installed in a new layer atop an existing slab.

Existing Hydronic heating systems, especially those with in slab heating improve chances of compatibility. Retrofitting hydronic pipes into/onto an existing  concrete slab is also possible although its performance improves if the slab is sub-insulated.

It is possible to install a heat core storage system adjacently, to an existing build, under the right circumstances where heat core pipes can installed subterraneanly adjacent to the existing building.
