High-Temperature Solar Heating without Water Circulation
The Hoyer Heat Center represents a new class of heating systems.
It operates without water, pumps, pressure circuits, or heat transfer fluids.
Instead, it uses:
-
direct high-temperature solar heat
-
solid-state thermal storage
-
controlled solid heat conduction
-
and intelligent thermal management
Heat is collected when it is freely available – from the sun – and stored for later use.
Why heating without water matters
Conventional heating systems depend on:
-
water circulation
-
pressure systems
-
pumps and valves
-
continuous operation
The Hoyer Heat Center avoids all of this.
By using solid materials instead of water, the system achieves:
-
no corrosion
-
no freezing risk
-
no leakage
-
minimal maintenance
-
exceptionally long service life
Two storage units – clearly defined roles
🔸 Small solid-state storage (daily / weekly)
-
handles daily operation
-
supplies domestic hot water
-
stabilizes transitional seasons
-
operates up to approx. 500 °C
-
equipped with perforated solid channels and diamond coating
-
fast and highly responsive
🔸 Large solid-state storage (seasonal)
-
used exclusively for long-term storage
-
charged during summer months up to approx. 850 °C
-
stores heat for 5–7 months
-
built from cost-effective solid materials
-
includes a metal layer for controlled heat release
-
designed for durability and thermal stability
The small storage works – the large storage secures winter heating.
Seasonal charging – realistic and reliable
Under real conditions, the main storage reaches its target temperature:
-
between August and September
At that point, the winter supply is secured.
Controlled winter heat delivery
During winter, heat is not released through the small storage.
Instead:
-
the large storage uses its own insulated solid heat channel
-
delivering heat directly into the heat center
-
where both storage channels meet
Sensors, electronics, and AI control the process fully automatically.
Suitable for homes and businesses
For residential spaces:
-
stable base temperature
-
reliable evening hot water
-
only occasional heating on cold days
For commercial users:
-
predictable process heat
-
low operating costs
-
independence from fuel markets
Electricity use – minimal and purposeful
Electricity is only required for:
-
mechanical motion of the heat transport system
-
control and regulation
The heat itself comes from the sun – free of charge.
Unlike heat pumps:
-
electricity demand does not peak in winter
-
stored heat is already available
Conclusion
The Hoyer Heat Center is:
-
a solar high-temperature heating system
-
a water-free heating technology
-
a long-term thermal storage solution
-
suitable for households and industry
The sun is not unreliable – conventional heating systems are.
