Stiebel Eltron Mini Series Tankless Water Heaters

Stiebel Eltron Mini Series Tankless Water Heaters

Economical and ultra-compact, the Stiebel Eltron Mini Series tankless water heaters are designed for low flow point of use applications where incoming water temperatures and pressures don't fluctuate greatly. As they are not thermostatically controlled, they are most suited to applications with relatively constant flow rates.

Like all other Stiebel Eltron electric tankless water heaters, the Stiebel Eltron Mini Series only uses power when hot water is demanded through the use of a sophisticated water flow sensor. This will eliminate standby thermal heat loss, which is common in traditional tank style water heaters, thus significantly reducing operating costs.
