A highly efficient proportional/modulation based solar PV hot water system at an affordable price. It diverts 100% of your surplus power to heat water & works even on cloudy days.

Designed and Made in the UK

Features

Modulation based solar PV surplus energy manager that monitors in-house usage and PV power production to divert almost all the available surplus power to the immersion heater to heat water. Its intelligent sensing technology prevents the export of surplus power to the grid for negligible returns and uses it for local consumption, meaning you can avail hot water free of cost!

Other features

MANUAL OVERRIDE / BOOST FUNCTION

Inbuilt override/boost facility to turn on the immersion manually if required.

WORKS WITH WIND TURBINES & HYDRO-POWER

SolarImmersion works with all sorts of grid-tied micro generation systems.

FREE HOT WATER WITH SOLAR PV

Use the free surplus power from solar PV for hot water even in winter.

LOWER ENERGY BILLS

Gas boiler works far less than normal, helping you to save on energy bills.

WORKS WITH CURRENT IMMERSION HEATER & TANK

No need to change the immersion heater or hot water tank to use SolarImmersion.

MULTIPLE LOADS

SolarImmersion can drive multiple loads, so when the water is hot enough and the thermostat cuts off, a second load could be activated.

SolarImmersion- It’s Green, It’s Intelligent, It’s Affordable

It Helps You Save Over £300 Per Year.

It’s the perfect solution to make the most of your PV installation & self-generated power. Take control of your generated power to save energy and make financial savings. Use the excess energy generated from a Solar PV/Hydro/Wind Turbine to heat your water for free.

It makes financial sense to use that extra power generated by your PV to heat water rather than exporting to the grid, as buying electricity and gas from the grid for heating water remains expensive. If you are on a feed-in tariff, you will still be paid for the power used to heat the water. Make the most of your feed-in tariff – use surplus electricity generated from your solar PV system for hot water and still receive payment for it!

  • Get hot water using the surplus from your existing solar PV.

  • Save money and improve the efficiency of your solar PV.

  • Reduce bills and still get your FIT payouts.

  • Reduce CO2 emissions.

  • Even works on cloudy days.

  • Use the solar PV power surplus in-house to heat water using SolarImmersion and prevent the unwanted export of electricity.

  • Doesn’t affect the solar PV system warranty.

  • The investment on SolarImmersion could pay itself back in less than 24 months.

  • Designed to last 25 years.

  • Maintenance-free with no moving parts.

  • Inbuilt overheating protection.

  • No plumbing alterations required.
