   It maintains water pressure and consistent supply of hot water across multiple hot water applications, and like its tankless cousins, it is efficient and can supply a continuous flow of hot water on demand. [6] The hybrid approach is designed to eliminate general shortcomings of other technologies.

3. Water heating - Wikipedia

   A safety device called a temperature and pressure relief (T&P or TPR) valve, is normally fitted on the top of the water heater to dump water if the temperature or pressure becomes too high. Most plumbing codes require that a discharge pipe be connected to the valve to direct the flow of discharged hot water to a drain, typically a nearby floor ...

   en.wikipedia.org/wiki/Comparison_of_pumps

   Different types of pumps are suitable for different applications, for example: a pump's maximum lift height also determines the applications it can be used for. Low-lift pumps are only suitable for the pumping of surface water (e.g., irrigation, drainage of lands, ...), while high-lift pumps allow deep water pumping (e.g., potable water pumping ...

5. Circulator pump - Wikipedia

   This avoids one of the principal challenges faced by the larger, two-part pumps: maintaining a water-tight seal at the point where the pump drive shaft enters the pump body. Small- to medium-sized circulator pumps are usually supported entirely by the pipe flanges that join them to the rest of the hydronic plumbing. Large pumps are usually pad ...
