How is DSH Different? First packaged Solar Heating system to take solar heat and convert it to an active, in floor, radiant heating system combined with Solar Hot Water and Low Cost Interseasonal Storage. The mass-storage allows the solar panel design to be optimized for winter with no worries about summer overheat. Stores summer valuable heat for use in dark times or winter instead of wasting it. Solar Panels that work well even down to -30 c backup typical hydronic boilers, heat pumps & demand boilers Optional open flame (log) boiler support

How is DSH Different? First packaged Solar Heating system with massive thermal low-caloric storage (30 -70 c). High temperature (75 c) Opt. storage for: Pools & Spas: Warm Snow Melt: Safety Laundry: Hotels, Hospitals, Car washes etc. Commercial Pre-heating

Why Low Caloric Heat? Low Caloric Radiant Heat allows: Typical max slab temp is 29. 5 c, low caloric. This type of system uses large volume, low caloric heat Simple fluid tempering mix to prevent slab overheating Lower temps greatly reduce parasitic heat losses Improved overall efficiency using slab thermal mass

The Patented DSH Heating System 1. 2. 3. 4. Roof mounted solar collectors absorb solar energy, efficient even in winter, using vacuum solar tubes. This heats a transfer fluid. The fluid directly heats pipes in the Floor Slab, Or: If the room temperature is satisfied, or slab thermal limit is reached, it travels to the Insulated heat core storage system under the slab. Safety limit = core cooling. When heat is needed and no solar is available (i. e. at night) the fluid is circulated from core to slab.

Residential comparison A typical heating furnace generates: • • • Noise Draft Dust & bacteria circulation Heat wall scrubbing Space robbing installation A typical DSH Mechanical system: • • • No Noise, Drafts, circulation Luxury radiant floor heat Stratified heating in prime location No heat wall scrubbing Space enhancing installation Opt: zoned heating on Thermostats

Warehouse Example

How it works: Reside. Ntial Even in the dead of winter, if the sun is out, the evacuated tube solar panels still function, and add direct heat to a home or facility. Solar heated fluid is pumped direct to the slab, adding heat to the concrete thermal mass which retains the heat over long periods. Insulation on all sides limits leakage to the home or office. Everything is controlled by a custom digital controller.

How it works: Once the room is up to temp or the slab limit has been reached, the system transfers all excess energy to thermal mass heat core storage. Solar heated fluid is pumped directly to the massive heat core, & over time, especially in summer, the core temperature at the top rises and stabilises based on demand, thermal transfer and insolation. In N America the bottom is also insulated to fully contain the stored heat energy.

How it works: When no solar heat is available, heat can be drawn from the heat core to the slab using the same piping already in place. Fluid heated in the core is pumped up to the slab, heating it. This is especially useful on bright solar days with cold nights as peak heat at the top of the core has had little time to escape and can be readily extracted.

What is important? Insolation value for the local area This is a measure of solar radiation energy received on a given surface area in a given time. Performance is affected by: • Insolation & Sun Angle • Temperature Extremes & Weather • Building efficiency – heat loss • Pollution • Roof or collector real estate • Building Thermal Demand • Hot water demand

GHG OFFSET & Results Every KWt of energy injected into a structure will offset 100% of the equivalent GHG (Greenhouse Gas) emissions for that site. SAVINGS: Every year, new systems compound the GHG savings in perpetuity Expected heating energy offset projections: 50% to 100% This chart is based on mixed variables

CANADIAN Re-ENGINEERING A redesign for the harsher Cdn. climate Added focus: Commercial Systems Solar Ev. T Panels with excellent performance in winter even at -30 c Drainback system for possible power outages during full insolation Digital Controller Canadian Insolation

SYSTEM Life Expectancy The life expectancy of this system is expected to reach beyond 30 years with only nominal servicing. Servicing to include system 5 yr flushes, detritus flush, solar panel tubes to be cleaned and general performance testing. Even hot areas in deserts require heat as homes suffer from night time thermal shock where temperature can drop from +40 c to <0 c.
