SECUSOLThe Solar Appliances
The SECUSOL system is pre-engineered and pre-wired. That makes it is easy to install and reduces potential mistakes.
The Wagner SECUSOL system can completely replace your conventional direct water heater.
SECUSOLOperation Range
• Max. length of pipe run: 50 ft (one way)
• 100 ft for the whole loop
• Max. height: 28 ft (between top of the collector and pump)
• System with one or two collectors available
SECUSOL Mounting Options
Flush mount Free standing
SECUSOLMounting Options
• Single collector
• 2 collectors one above the otherConnection: serial
• 2 collectors - next to each otherConnection: parallel
SECUSOL Glycol
Why would we use glycol in a drainback system?
1. Corrosion protection
2. Freeze protection
because shit happens…
We run the SECUSOL system with 33% glycol!

SECUSOL - The Easy Way to Avoid Stagnation Problems
Protect solar liquid from overheating
SECUSOL System Function
How does the SECUSOL system perform on a nice sunny summer day?
T1: 80 °F
SECUSOL System SunctionEarly Morning Situation
T2: 55 °F
When the system is not running, no solar liquid is in the collector. The liquid stays in the HX.
In case of a power blackout there will be no overheat issue.
SECUSOL System FunctionMorning Situation
T1: 85 °F
T2: 55 °F
System kicks on when delta T between collector and lower tank is at 30°F.
Heat transfer liquid is pumped up to the collector. The air is forced into the upper part of the HX.
SECUSOL System FunctionMorning Situation
T1: 67 °F
T2: 57 °F
After the filling time the pump goes into the speed controlled mode. That saves electric energy and increases the efficiency.
In the oversized heat exchanger is enough space for both, a perfect heat transfer and expansion.
SECUSOL System FunctionSituation around Noon
T1: 203 °F
T2: 181 °F
When collector temperature rises, pump speed increases to maintain the standard delta T of 40 °F.
The system will stop when either the max. tank temperature (182F) or the max. collector temperature (270F) is reached. Or when the delta T drops below 6F.
SECUSOL System FunctionAfternoon Situation
T1: 203 °F
T2: 182 °F
When the pump stops, the solar liquid will drain back into the heat exchanger. The collector remains empty.
SECUSOL System FunctionAfternoon Situation
T1: 203 °F
T2: 182 °F
The air will rise up into the collector while the solar liquid drains down into the heat exchanger.
Overheating will never occur with SECUSOL!
Max. tank temperature is reached. System stops!
SECUSOL System FunctionAfternoon Situation
T1: 406°F
T2: 182 °F
Note: Our collector can easily handle temperatures way over 400 °F.

How does the SECUSOL system perform on a cloudy winter day?
SECUSOL System FunctionWinter Situation – with Overcast Sky
T1: 34°F
T2: 55°F
When there is no solar yield, the 4.5 kW heating element will provide all the heat needed for shower, dishwasher and washing machine. Just like any other water heater.
T3: 155°F

T1: 34°F
T2: 55°F
You could also use the upper HX and hook up your oil or gas boiler as a back-up for the winter.

You can keep the existing tank and still benefit from SECUSOL Solar yield!
SECUSOL Preheat ApplianceSituation with no Solar Yield
T1: 23 °F
T2: 55F
T: 155F
When there is no solar yield, the water coming from the street will just pass the SECUSOL tank. It will be heated up as usual by the conven-tional water heater.
SECUSOL Preheat ApplianceSituation with Solar Yield (Winter or Summer)
T1: 190 °F
T2: 150F
T3: 160FT: 155F
In normal operation, the street water will be pre-heated in the SECUSOL tank. Most of the year the conven-tional water heater does not have to fire. The heat will then be provided just by the sun!
