Climate Control & Ventilation Customizations for Geodesic Dome Living
You can install a chimney, mini-split, or other HVAC systems in your Ekodome®, as long as they’re planned and installed correctly.
Whether you’re building a dome house, eco-dome, or greenhouse home, proper airflow and temperature control are key to year-round comfort.
Below is a breakdown of how to safely and effectively integrate these systems into your geodesic dome kit:
Chimney Flue Integration
You can add a chimney flue to your Ekodome by sending us the exact dimensions and preferred location of the flue. We’ll pre-cut a hole into the appropriate panel before shipping.
We recommend choosing a flue that exits through the side wall rather than the ceiling. This gives you more flexibility when selecting your dome size and simplifies both installation and sealing.
Installing a Mini-Split System
Mini-splits are a popular and efficient way to heat and cool your dome—especially when used with the Pro Series.
What to know:
-
Indoor Unit Placement:
Mount on a custom interior frame or freestanding module. Positioning near the upper section helps with circulation. -
Routing Wires & Lines:
Avoid drilling into panels. Instead, route refrigerant lines and wiring along the dome’s struts using conduit, or underneath the deck/foundation to keep the setup clean and weather-protected. -
Sealing Tips:
Seal conduit entry points at the platform/foundation level with foam insulation or weatherproof sealant to prevent air or water leaks. -
Outdoor Unit Placement:
Place on a stable, ventilated platform just outside the dome, away from snow accumulation or debris.
HVAC Systems in Ekodomes
-
Recommended For: Pro Series domes
-
Why: They offer high-performance insulation and are built for year-round living in extreme climates.
HVAC Options for Pro Series Domes:
-
Mini-splits
-
Ducted floor systems
-
Radiant in-floor heating
-
Electric baseboard heaters
Work with a licensed HVAC contractor to determine the best solution based on your climate, use case, and layout preferences.
Climate Control in Original Series Domes
For Original Series domes (non-insulated), full HVAC systems are not recommended. Instead, we suggest:
-
Passive ventilation
-
Fans or small plug-in heaters
-
Thermal mass elements (e.g., water barrels or stone flooring)
These options are ideal for greenhouse domes, seasonal spaces, or mild climates.
