This document provides support to installers to trace and resolve issues at the
installation stage or during service. Symptoms covered in this document are:
Incorrectly Displays "Water Tank Hot" or "Heating by Solar 0.00."

What is the Solar iBoost Connected to? -
1. It should be connected electrically from the Solar iBoost directly onto the
immersion which is a purely resistive load. The immersion should be rated
≤ 3kW and it MUST have a built-in thermostat.
2. There must not be any electronic, relay or contactor switching devices
between the Solar iBoost and the immersion. Additional system controls
may conflict with the controlled power output of Solar iBoost. Where a
thermostat has a neutral terminal the installer should check that the load
remains purely resistive.
CAUTION! Connection through switching devices may cause irreparable
damage to the Solar iBoost invalidating the warranty.
Check the Boost function is working?
Press the "Boost" button to display on for 15 minutes
as shown. You should become aware of the
immersion cutting in to run from the grid within about
1 minute and the display will count down minutes.
Scenario 1—Water Tank Hot display returns but tank is not hot.
The electrician should perform these tests:
A continuity test of the thermostat.
·
A continuity and resistance (20 Ohms) test of the immersion rod.
·
Defective components should be replaced as required and the system
re-commissioned. Where 2 immersions are installed both should be tested. If
the secondary immersion thermostat has tripped further investigation of the
causes are recommended.

Questions and answers
Hi ! My iboost is showing “water Tank HOT” after the immersion heater thermostat is satisfied but then won’t switch back on again once the stat is calling for heat again. I have to turn the iboost off at the fused spur to return back to “Water Heating OFF” again before I can boost it again. I’ve checked the immersion heater resistance and it’s 20.1 ohms.
The Marlec Solar iBoost+ may display "Water Tank HOT" and not switch back on after the immersion heater thermostat is satisfied due to the following reasons:
1. Thermostat Issue – The immersion heater thermostat may not be resetting correctly. A continuity test should be performed to check if it is functioning properly.
2. Immersion Rod Fault – A continuity and resistance test (20 Ohms) should be conducted on the immersion rod. If faulty, it should be replaced.
3. Tripped Secondary Thermostat – If a dual immersion system is in place and the secondary immersion thermostat has tripped, further investigation into the underlying cause is needed.
4. Wiring or Connection Issues – Ensure compliance with the installation manual and check that the terminal strip link wire is secured (for the original model).
5. Boost Function Behavior – If the boost function continues to operate unexpectedly, it should be stopped manually and the wiring connections should be verified.
If troubleshooting does not resolve the issue, an electrician should inspect the system.
