🔋 Battery storage
no additional saving
A battery increases solar self-consumption, reducing grid draw further.
Primary heating system
Biogenic carbon note: Biomass CO₂ is excluded under IPCC biogenic carbon accounting (IPCC 2019 GL Vol 2). Only non-CO₂ greenhouse gases (CH₄, N₂O) are included here. This assumes certified sustainable sourcing. Uncertified wood may carry deforestation risk not captured in this estimate.
