Common Apricus Solar Hot Water Problems We Fix
Apricus evacuated tube systems are high-quality but have unique failure points. We're Brisbane's specialists in heat pipes, manifolds, and tube replacements with 15+ years experience.
Evacuated Tubes Lost Vacuum
Most unique Apricus problem! Copper heat pipes inside each glass tube transfer heat to the manifold. When they fail, performance drops dramatically even though tubes look fine.
- ✓Barium getter test: Look at base of tube - SILVER = good vacuum, WHITE/MILKY = vacuum lost
- ✓Tube feels warmer to touch than others
- ✓Visible condensation inside the vacuum space
- ✓Tube was cracked and "repaired" (can't repair vacuum!)
- ✓Random tubes performing poorly
Common causes: Impact damage (hail, branches, birds), manufacturing defect in glass seal, age (15-20 years), thermal stress cracks from extreme temperature changes
Heat Pipe Failures Inside Evacuated Tubes
Panel condensation problems: Copper heat pipes inside each glass tube transfer heat to the manifold. When they fail, performance drops dramatically even though tubes look fine.
- ✓Collector only reaching 45-50°C on hot sunny days
- ✓Tank barely warming despite full sun
- ✓Need to run booster constantly
- ✓System worked great for 5-8 years, now lukewarm
- ✓Multiple tubes feel equally hot (no heat transfer)
Testing individual tubes: Use infrared thermometer on outside of glass tube bottom while pump running. Failed heat pipes read 3-4°C HOTTER because they're not extracting heat to manifold properly.
Manifold Temperature Sensor Failure
Sensor reading 25-27°C in full summer sun! This is THE most reported Apricus issue on forums. Manifold is scorching hot but sensor says it's cool, so pump never activates.
- ✓Valves opening at 10-14°C (way above freezing)
- ✓Sensor reading only 25-30°C during peak sun
- ✓Pump not activating despite hot collector
- ✓Sensor loose in manifold socket (not glued in)
- ✓No heat sink grease for thermal contact
- ✓Sensor wiring corroded from weather
- ✓Water ingress in sensor porthole (design flaw)
- ✓Sensor reads correctly up to 55°C then random numbers
Critical fix: Sensor MUST be snug in manifold slot with PLENTY of heat sink grease for thermal contact. Many installers skip this! Sensor just touching metal isn't enough.
Manifold Cracking/Splitting (Freeze Damage)
Catastrophic failure! Manifold splits open from freezing water inside. System dead until manifold replaced. Expensive repair that's often warranty-denied.
- ✓Blistering hot water from taps after dark
- ✓Temperature sensor failed to detect freezing conditions
- ✓Pump didn't circulate water for freeze protection
- ✓Power outage during cold night (pump can't run)
- ✓Isolation valves closed trapping water in manifold
- ✓Insufficient insulation on manifold
Apricus freeze protection: Controller circulates water once temp falls below 4°C. System rated to -15°C. BUT if sensor fails, pump fails, or power is out, freeze protection doesn't work!
GRUNDFOS CIRCULATION PUMP FAILURE
Pumps last 5-8 years typically. Apricus uses quality Grundfos pumps but they still fail. Silent operation makes failure hard to detect - system just stops working!
- ✓Pump completely silent (should hum quietly)
- ✓No vibration when touching pump body
- ✓Manifold getting dangerously hot
- ✓Tank not warming despite sunny weather
- ✓Controller shows high collector temp but no pumping
- ✓Pump failed within 2 years (warranty issue!)
Why pumps fail: Bearing wear, impeller damage from debris, electrical failure, overheating, hard water scale buildup, cycling wear from frequent starts/stops.
Resol DeltaSol Controller Failures
Controller failed at 13 months - just out of warranty! Common complaint. Resol DeltaSol BS/4 and BS/2 controllers are German-made quality but failures still occur.
- ✓Error code 888.8 displayed
- ✓Incorrect temperature readings
- ✓Pump running continuously at night (cooling water!)
- ✓Pump not activating despite temperature differential
- ✓Display blank/no power
- ✓Faulty resistor in circuit (common at 13 months)
- ✓New controller didn't fix problem (was sensors!)
Diagnostic trap: Customer replaced controller for $$$. Problem persisted. Real issue was failed heat pipes! Always test sensors and heat pipes before replacing controller.
Heat Pipe Migration/Disengagement
Heat pipes sliding down inside tubes! Bulbs at top of heat pipe disconnect from manifold sockets. System looks fine but produces no heat. Apricus redesigned with spring plates to fix this.
- ✓Sudden dramatic performance drop
- ✓Tubes look normal, vacuum intact, but no heat
- ✓Bulbs visibly lower in manifold sockets
- ✓Affects multiple tubes gradually over time
- ✓Happened around 2-3 years after installation
The Problem: Original Apricus design had heat pipes held by friction alone. Thermal expansion/contraction caused pipes to slowly migrate downward. Bulb loses contact with manifold = no heat transfer.
Tank Anode Depletion & Warranty Denials
Tank leaked at 6 years - warranty DENIED! Apricus/Thermann have 10-year tank warranty BUT strictly enforce anode replacement requirements. Many claims denied.
- ✓10-year tank warranty sounds great
- ✓Tank must be "regularly serviced"
- ✓Anode must be replaced "within recommended periods"
- ✓No specific interval stated clearly
- ✓Tank leaks at 5-6 years from anode depletion
- ✓Warranty claim: "anode degraded and not replaced" = DENIED
Reality check: Almost NO homeowners replace anodes on schedule. Most don't even know they exist. Strict enforcement appears designed to avoid warranty claims.
System Running at Night (Pump Won't Stop)
Pump circulating after dark - cooling your water! System should shut off when collector cools down. If pump runs all night, it's actually COOLING your tank water.
- ✓Controller S MX (max temp) setting too high
- ✓Temperature differential settings wrong
- ✓Collector sensor failed reading incorrect temp
- ✓Controller stuck in manual ON mode
- ✓Freeze protection activating unnecessarily
Controller adjustment: Resol controllers are very configurable but need proper setup for your climate. Brisbane systems vs Victoria systems need different settings. Apricus support can walk you through parameter adjustments over phone.
Tube End Seal Maintenance Required
Often neglected maintenance! Apricus systems require tube end sealing maintenance every 2-3 years. Most owners never do this, leading to gradual performance decline.
- ✓Rubber seals at base of each tube
- ✓Seal between tube and manifold
- ✓O-rings and gaskets aging from UV/weather
- ✓Clips holding tubes in frame
Why this matters: Degraded seals allow air infiltration into vacuum spaces (destroys insulation), moisture entry causing corrosion, tube movement in high winds, heat loss at manifold connection points.
Air Locks in System
Pump running but no water flow! Air trapped in system prevents proper circulation. Common after installation, repairs, or when system runs dry.
- ✓Pump operating but no flow felt
- ✓Gurgling noises in pipes
- ✓System performance suddenly dropped
- ✓Happened after repairs/maintenance
- ✓Manifold overheating despite pump running
Proper purging: System must be properly commissioned with careful air bleeding. Apricus installation manual has specific purging procedure. Rushed installations skip this!
