This invention automatically reclaims heat from residential wastewater, onsite. The apparatus is simple, inexpensive, has no moving parts and requires no maintenance in its operation. Recovered heat preheats feedwater of the normal hot water tankyear round. Passage of cold wastewater has no adverse effect. Lowers overall energy consumption for short payback period. Provides buffer to energy peak-demand periods. Its design includes: a simple non-pressurized vessel adaptable for thermal storage; positive safeguard against fresh-water contamination.; low in cost; fittable to existing houses, multi-dwelling buildings, laundromats, restaurants, hotels, etc.
