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.

Installation was all straight forward. Everything set up for you. System has produced a net surplus since installation. Gerry TrainorTrustindex verifies that the original source of the review is Google. Stuart installed my solar array and battery storage system a numbers of years ago Communication was fantastic and everything was explained and done as and when it was supposed to. From enquiry to installation was less than 2 weeks !! Since installation my electricity usage has dropped by about 70%, and my annual costs now are about £250...but I got last year £400 for what I exported so actually I'm getting free electric and £150 on top each year !!! With prices only set to continue to increase I'm just so glad I invested in solar and had the system installed by the guys at Eeco Energy. l cannot recommend highly enough !!

Eeco energy are delighted you are pleased with our service and product. Thank you for your business and look forward to being of service again simon cTrustindex verifies that the original source of the review is Google. Excellent service at a reasonable price. Highly recommended. Stuart provided expert advice from outset. Installation lead time was less than 2 weeks - roofing and electrical teams did great job over 2 x days and I was up and running the next day. The Duracell inverter and battery system (2 x 5 kW/hrs) was positioned in utility room (instead of roof space). This was a good decision as they look ok and don't appear out of place. Currently in the process of getting Econmy7 meter installed so I can charge batteries at night at low rate using the app. Even at end of November on a fine day I get an impressive solar output of about 3-4 kW, which charges the batteries on top of household usage. Although the Duracell system is modular I would recommend adding the batteries from the outset as the increase the efficiency of the system significantly

Thank you for kind words. Barbara SmythTrustindex verifies that the original source of the review is Google. Stuart gave excellent explanation of your products. Talked at length of where panels could best be positioned and how batteries could assist in energy efficiency and reduced bills. He was very patient and very willing to help with the setting up of the relevant apps. Our system was installed on time and without any hiccups! Although system had only been installed for 1 week and it has been mostly dull, we are already reaping the benefits. 😊👍
