Standard, Deluxe, or Premium Complete Kits offer an inclusive parts list that incorporates the plumbing and manual control components necessary for a hassle-free installation.
Standard/Direct Kit - ProgressivTube system uses a stand-alone configuration as the single source for providing hot water.
Function: When hot water is required, solar heated water is drawn from the collector unit and distributed directly to the points-of-use.
Applications: Best suited for use in equatorial and tropical type climates where hot-to-very-hot temperatures exist year round (such as the Caribbean, Central Africa, northern South American) and conventional water heaters are rarely used, or electrical power is unavailable - but free hot water is desired or required.
Performance: Hot water output is dependant on available solar radiation, and may be temporarily interrupted by inclement weather.
Control Valve: No control valve is necessary.
Deluxe/2-Way Kit - ProgressivTube system used in conjunction with a conventional water heater, or an instantaneous water heater.
Function: When hot water is required, solar heated water is drawn from the unit directly into a conventional or tankless water heater, thus eliminating or reducing electricity or gas usage required for heating water. Hot water is then distributed directly to the points-
of-use. The water heater must remain turned on to provide backup heat as required, and to maintain a ready supply of hot water.
Applications: Well suited for use in tropical, sub-tropical "SunBelt", and temperate type climates where mild-to-hot temperatures exist year round and conventional water heaters are always used - and free hot water is desired or required.
Performance: Hot water output is dependant on available solar radiation. Backup provides constant supply when solar performance is temporarily interrupted by inclement weather.
Control Valve: A manual 2-Way plumbing configuration allows for isolation of the ProgressivTube system for maintenance or winterizing, and is typically adjusted on a seasonal basis only.
Premium/3-Way Kit - ProgressivTube system used in conjunction with a conventional water heater, or an instantaneous water heater.
Function: When hot water is required, solar heated water is drawn from the unit directly into a conventional or tankless water heater, thus eliminating or reducing electricity or gas usage required for heating water. Hot water is then distributed directly to the points-of-use. The water heater must remain turned on only when in the backup mode to provide heat as required, and to maintain a ready supply of hot water.
Applications: Well suited for use in tropical, sub-tropical "SunBelt", and temperate type climates where mild-to-hot temperatures exist year round and conventional water heaters are always used - and free hot water is desired or required. It allows the selection of direct solar or solar with backup heater.
Performance: Hot water output is dependant on available solar radiation. Backup provides constant supply when solar performance is temporarily interrupted by inclement weather.
Control Valve: A manual 3-Way plumbing configuration allows
direct operation during periods when there is sufficient solar energy and no backup is required, and is typically adjusted when sporadic inclement weather conditions reduce solar effectiveness.
This maximizes overall operating efficiency and eliminates standby heat loss from the backup heater. The valves also allow for isolation of the ProgressivTube for maintenance or winterizing.
Single Collector Panel - does not include any plumbing or control components. It is intended for:
- add-on collector panels to Standard, Deluxe, or Premium Systems Kits when additional panels are desired to increase capacity
- Large commercial projects requiring multiple collector panels
replacement change-out of damaged or obsolete collector panels
- Custom applications requiring only the use of collector panels
