Webb1 mars 2024 · The relationship between heat loss of water supply pipes and water supply pipe spacing is shown in Fig. 8. The heat loss of medium temperature pipe was proportional to water supply pipes spacing, and the relationship was roughly linear. For high-temperature pipe, the heat loss had extreme value. WebbFor insulated piping, differences in heat loss (horizontal compared to vertical) will be minimal (lower than 1%). Flat horizontal surfaces in still air (e.g., the tops of heated tanks) will have higher heat losses than vertical surfaces, while horizontal surfaces with heat flow down (e.g., the bottoms of heated tanks) will have lower heat losses than vertical surfaces.
