Luthmore describes its product as a battery-enabled, all-electric “combi-style” boiler intended to deliver a familiar gas-combi experience (instant hot water plus central heating) but with zero on-site emissions. The core idea is that the unit stores energy in Lithium Iron Phosphate (LFP) batteries, charging during cheaper offpeak periods (and/or from solar), then releasing that stored energy to deliver high power when you need hot water or heating.

In performance terms, third-party trade coverage and industry write-ups commonly reference up to ~30 kW for domestic hot water and ~10 kW for space heating, packaged as a compact, wall-mounted, tankless appliance designed to fit where a typical combi would and connect into broadly familiar wet heating pipework.
