About Immersion Heather Controllers

An immersion heater controller is a clever way to manage your energy and save money on hot water.

Instead of exporting surplus power from your solar system back to the grid, these controllers redirect that energy to heat your water.

In effect, this creates free hot water from your own self-generated green energy.

With intelligent features like programmable boost timers, you can make sure your system works exactly when you need it, cutting down on grid reliance.

In many cases, you might not even need to turn on your boiler for months during warmer seasons. It’s a simple, smart solution for better energy efficiency.

Why Choose eddi for Your Home?

Eddi is the ultimate immersion heater controller, designed to make the most of your self-generated power.

Instead of sending surplus energy back to the grid, Eddi diverts it to heat your water or power your heating system, giving you free hot water and reducing your reliance on the grid.

With intelligent energy management, Eddi constantly monitors your power use, ensuring you’re running as efficiently as possible.

Its built-in programmable boost timers mean you’ll always have hot water when you need it, while maximising savings from your solar system.

It’s easy to use, highly efficient, and built to help you save money while making the most of your green energy.

 Trustindex verifies that the original source of the review is Google. We had solar panels installed by EECO Energy (Solar NRG) in late August 2026.  We have been delighted with the energy production from the system.
We have reduced our electricity bill to a fraction of what they were.
We contacted EECO and their sales rep Philip Wilson, visited us within a few days of our phone call.  He explained how the system works, and advised us what our options were, regarding a suitable system for our house.  He took plenty of time, to answer all our questions and at no point did he pressure us into a sale.  Philip advised us regarding future proofing the system as requested by us, e.g. if we invested in an electric vehicle and also regarding our electrical requirements for our home.
When we decided what we required, Philip arranged for the solar panels to be installed, followed a couple of weeks later for the electrical installation of the software.  This work was carried out on the dates given, and there was no mess or disruption to our home.  All of the personnel who installed our system were extremely helpful and polite, and explained everything to us.
All the office staff, Messina, Deione and Jessica arranged for all the necessary paperwork to be completed on our behalf, including payments of all fees, enabling us to export any excess electricity which we did not use in the home, along with any queries we had.
Any queries which we had post installation, were dealt with promptly to our satisfaction by the relevant team members.
We would highly recommend Philip for his knowledge and when we needed advice, he came back to us promptly and also the office staff who were very friendly and proactive.
We have been delighted with the performance of our solar panel system and would have no hesitation in recommending EECO Energy for the installation of solar panels.

However the team where really great and managed to complete the install as planned.  I am very happy with the quality of the installation.  It is very neat job, they where very professional.  They where also very helpful and friendly.  The after installation documentation has arrived. I would happily recommend.

Great support from Phillip who gave us the information we needed to decide on the system that worked best for us and for making sure the installation was a neat and tidy job. We are very pleased with how ECCO managed the process from our decision to installation and the aftercare they provide.

 Trustindex verifies that the original source of the review is Google. I was looking for ways of bringing down the cost of my electricity. My standing order of £90 plus per month and heading upwards.
I contacted a number of companies for quotes including EECO where I met Philip Wilson who took time taking me through the whole process and what I could achieve by investing in solar.
I decided EECO was my company of choice. Philip and his team took us through the complete process, and dealing effectively with any problems which arose  which were minor. . My direct debit has gone from £95 to £69 a month in 1.5 months. I also have credit with my electricity supplier. That’s a result of.  Philip is always available for advice.
Wish I had done it sooner. I have not obtained any incentive by EECO this my true thoughts on Solar and EECO

 Trustindex verifies that the original source of the review is Google. Absolutely delighted with the service from EECO Energy from start to finish.

A special mention to Simon Trainor, our client liaison, who was first class throughout. He was extremely responsive, explained everything clearly and continues to quickly answer any questions we have.

From confirming the system, the full installation was completed within two weeks, which was brilliant. The roofing team and electricians arrived when they said they would and made sure everything was installed neatly and discreet.

We shopped around beforehand and EECO also offered the best price for the system we wanted.

The solar and battery combination has been brilliant. We're now at the point where, even on an overcast day, the house is basically running for free from the solar and stored battery power.

Great price, professional installation and, most importantly, excellent service before and after the job. Would happily recommend EECO Energy.

 Trustindex verifies that the original source of the review is Google. Staff are great, big thanks to Simon and Deione, they guided me through the process, helped in every way, a 100% trustworthy company. Installation neat and tidy, roofers A+ electrical install again A+, after service excellent, just lift the phone and like Mr Ben they just pop out of nowhere to answer any queries. Biggest mistake should’ve did it 6 years ago.

 Trustindex verifies that the original source of the review is Google. EECO Energy recently completed a solar PV and battery installation at our home in Lisburn, and we couldn’t be happier. The roofing and electrical teams were skilled, tidy, and clearly took pride in their work.

From the first conversation with Stuart, to the installation, the customer service was consistently excellent.

The whole process was smooth, well‑explained, and professionally delivered. We’d happily recommend EECO Energy to anyone looking for a reliable solar installer.
