Solar Thermal is Pure Green Heat
It significantly lowers related Greenhouse Gas Emissions.
OpEx & Carbon Savings are significant
New Governmental properties can benefit hugely from integrating the DSH technology into any new heating system. Benefits include but are not limited to: OpEx reductions and 100% Carbon emissions offset reduction. Some existing properties can also be retrofitted, especially those with existing Hydronic Heating
The system can scaled up to suite any design assuming the corresponding areas are suitably designed with respect to adding the storage area as well as sufficient room for the engineered solar array.
As a rule an ideal candidate for heating would be a large area building on a near grade sub-insulated slab. Warehousing for example or Sports complexes, especially those with Swimming Pools, can greatly benefit in both OpEx and GHG emissions reduction.
Commercial payback can be quite short, and given the possibility of government subsidies, the number drops even more.
Added Design Requirements:
There are very few added design requirements. Most buildings have frost walls and insulation all of which help offset the cost of adding the thermal in-ground storage system.
If a property has a slab foundation, reasonable solar access, and up to 2 floors, then it can be considered a prime candidate for the DSH system.
More floors can be considered on a case by case basis. Deep U/G parking can be problematic for the heat core, and are quoted on a case by case basis. Access ramps and footpath can be heated for snow and ice melting.
The heat core storage system uses a specially designed, insulated sub-surface geo-strata, to provide massive, low cost thermal mass storage.Added typical design requirements are nominal:
A thermal heat core storage area under the slab needs to be added to the foundation design. This heat core storage has an insulated perimeter plus insulation under core and under slab.
- Perimeter insulation, sub-slab with ext vapor barrier
- Thermal mass sand layer under sub-slab HDPS, O2 proof PEX installed in the lower 50mm.
- Energy Efficient design, with Hydronic heating: of slabs. Backup can still be gas (demand) boilers or even Heat Pumps
- Piers or similar are a non-issue
- Roof design allocation and rated for solar panel array, typically flat roof.
- Conduit for sensor wires and hydronic pipes from roof to pump station.
- Std Hydronic heating in slab.
- Roofs are not the only location worthy of consideration if solar roof real estate is limited or not easily available.
The heat core must be low cost and yet massive to store the huge influx of thermal energy in summer. The size is engineered to allow deployment of enough solar panels to directly heat in winter when the sun is active.
Depth will vary with location, size, and design
