Systems like the Takagi TK-3 tankless water heater can heat your radiant loops using propane backup. Expect installation costs between $3,000-$5,000 for a complete tiny home system, but you’ll save significantly on long-term heating expenses.
Installation Tips for Tiny Home Foundations
Insulate beneath your radiant system with at least R-10 foam board to prevent heat loss to the ground. Your subfloor thickness matters – you’ll need minimum 1.5 inches for electric mats and 2 inches for hydronic tubing.
Consider thermal mass flooring like tile or concrete for maximum heat retention. Wood floors work but require careful temperature monitoring to prevent damage – keep surface temperatures below 85°F for hardwood installations.
Thermal Mass Heating: Storing and Releasing Heat Naturally
Thermal mass heating systems capture heat when it’s available and release it slowly over hours or even days. This storage approach perfectly matches off-grid living where consistent energy isn’t always guaranteed.
Rocket Mass Heaters for Extended Heat Output
Rocket mass heaters burn wood incredibly efficiently and store that heat in surrounding thermal mass like cob or brick. You’ll get 12-24 hours of steady warmth from just one firing session.
The Liberator rocket mass heater costs around $2,000-3,000 installed and can heat up to 1,500 square feet. These systems burn so cleanly they produce almost no smoke after the initial startup phase.
Masonry Heaters and Heat Storage Walls
Masonry heaters like Finnish contraflow designs store massive amounts of heat in stone or brick mass. You fire them once or twice daily and enjoy consistent radiant warmth for 12-18 hours.
Trombe walls use south-facing glass and thermal mass to capture solar energy during the day. The 8-12 inch thick masonry wall releases stored heat throughout the evening hours when temperatures drop.
Incorporating Thermal Mass in Small Spaces
Water-filled containers work excellently as thermal mass in tiny spaces since water stores more heat per cubic foot than masonry. Place 55-gallon drums or smaller containers near your heat source.
Phase change materials (PCMs) like BioPCM store and release heat at specific temperatures without taking up massive space. These panels can be integrated into walls or furniture to add thermal mass without sacrificing precious square footage.
Heat Pumps: Modern Efficiency Meets Off-Grid Living
