The Aquastar 1000P small gas tankless water heater is ideal for cottages, camps, and other specific applications where a small volume of hot water is desired. Its compact size means you save valuable floor space. This is the compact propane tankless hot water heater for low-volume applications. This unit is designed to be vented vertically (roof).

The 1000P Aquastar point of use water heater can be used for sinks or in warm climates a low flow shower (2.6 gallons per minute with a 45 degree temperature increase). Note: a standard shower uses approx. 2.5 gallons per minute and the 1000P is not likely strong enough to support this unless the inlet water temperature is warm.

The unit is constructed with stainless steel and aluminum with its internal water parts solid copper and brass. Unlike tank heaters, every part is replaceable or recyclable.
