Solar Pumps & Valves

Solar heating pumps and valves are a necessary part of a solar heating system.   The pumps used in solar heating applications need to be high temperature.rated as do any solar valves.  Solar valves are used to control the heat energy by moving this energy to different areas such as a home heating application or  a solar swimming pool heater

A solar pump also needs to be capable of handling the head pressure of a solar heating loop.  It is also important that the solar water heater has the ability to change speeds so that the solar water heater can maximize its performance based on the manufactures recommended flow rate.
