Product Information
Full details
The Marlec Solar iBoost+ is designed for homeowners with solar PV systems who want to maximize self-consumption by diverting excess energy to heat their domestic hot water. It provides the key benefit of significantly reducing reliance on grid energy for hot water production, effectively turning surplus electricity into thermal storage. A primary caveat is that it requires a compatible immersion heater setup and the installation of a clamp at the household meter, which may necessitate professional assistance for those uncomfortable with electrical wiring.

FAQs
Does it heat my water if there is no sun?
Yes, you can manually trigger a top-up using grid power or set a timer to ensure hot water is available when needed.
Do I need a new water tank?
No, the Solar iBoost+ works with your existing standard immersion-heated hot water tank.
Is the wireless connection secure?
Yes, the Sender and the iBoost+ unit are paired to communicate securely within your home network.
Can I install this myself?
It is strongly recommended to have a qualified electrician perform the installation, as it involves working with high-voltage mains electricity.
How much money will I save?
Savings vary based on your solar system size and hot water usage, but it significantly reduces the need to heat water using gas or grid electricity.
Troubleshooting

Check the power supply to the unit and ensure the circuit breaker is active.

Setup, Compatibility & Care
Installation involves two primary components: the Sender clamp, which must be attached to the live meter tail in your consumer unit, and the Solar iBoost+ main unit, which is typically wired between the mains supply and the immersion heater. Compatibility requires a standard immersion heater with a physical thermostat. For care, ensure the display is kept clear of obstructions. The unit is designed for a 'fit and forget' experience, though it is recommended to periodically check the front display during sunny days to confirm it is actively diverting energy to the hot water tank.
