heat water with solar in devon

Heating water using solar panels has become an increasingly popular and sustainable method for meeting the energy needs of homeowners. A highly efficient and innovative solution for harnessing solar energy to heat water is the Eddi system developed by Myenergi. If you already have solar panels installed, keep reading!

what does the eddi power diverter do?

The Eddi system is specifically designed to divert surplus electricity generated by solar panels to heat water, maximising the utilisation of renewable energy. By intelligently managing and redirecting excess power, the Eddi system ensures that solar energy is effectively used to provide hot water, reducing reliance on traditional energy sources and lowering carbon emissions.

With its intelligent and eco-friendly features, the Eddi system from Myenergi offers homeowners in Devon & Cornwall a viable and environmentally conscious option to embrace renewable energy solutions and reduce their ecological footprint.

of a typical household’s energy consumption is from heating water

works with new or existing solar panels

Solar hot water systems can seamlessly integrate with both new and existing solar panels, maximising the utilisation of renewable energy for efficient water heating.

environmentally friendly & saves on energy bills

Solar hot water systems are not only environmentally friendly but also offer significant cost savings, making them a sustainable and economical choice for heating water.

super efficient & reliable heating source

eddi can heat your water using lower amounts of solar generation (<1kWh) whereas heat pumps & EV chargers usually require around 1.4kWh before they kick in.

eddi diverts any excess solar or wind generation back into the property, to help maximise the consumption of your self-generated energy opposed to exporting out to the grid, in turn you can heat water with solar – for free!

eddi can heat your water using lower amounts of solar generation (<1kWh) whereas heat pumps & EV chargers usually require around 1.4kWh before they kick in, meaning eddi can trickle charge your hot water when the heat pump isn’t active.

eddi will switch between heat appliances dependent on the amount of generation and the heat of the water at any given time, and will select the most efficient way to keep the water heated.

eddi supports destratification which keeps hot water circulating around the tank, where traditionally hot water rises to the top of the tank. The secondary circulation function will help to circulate hot water around your property at peak times to ensure the hot water is more instant.

Use the myenergi app to adjust and optimise the settings of your eco-smart tech devices, to achieve maximum efficiency of your heat appliances and other smart devices. Set timers for your boiler through the myenergi app.

eddi is a future-proof, eco smart technology, and connects to the internet through WiFi or Ethernet, allowing it to fully integrate and work in harmony with other future smart-grid-ready products around the home, such as heat pumps, battery storage systems (such as libbi) and EV chargers (such as zappi)

what our homeowners say


It might be obvious to some what a solar hot water tank is, but just in case you are curious, here’s some very frequently asked questions about them. Let us know if you have any other questions!

A solar hot water tank is a system that uses solar panels to heat water for domestic use. The system typically consists of a set of solar panels, a storage tank, and a pump to circulate water.

Solar panels on the roof or other nearby location absorb the energy from the sun’s rays and transfer it to a heat transfer fluid. The fluid then circulates through a coil in the water tank, transferring the heat to the water.

Yes, a solar hot water tank can be used year-round in the UK, even during the winter months. While the amount of energy produced may vary, the system can still provide hot water.

The cost of installing a solar hot water tank varies depending on several factors, such as the size of the system, the complexity of the installation, and the location of the property. However, homeowners can typically expect to pay several thousand pounds for the installation.

Yes, homeowners in the UK may be eligible for various incentives or grants to help with the cost of installing a solar hot water tank. For example, the government offers the Renewable Heat Incentive (RHI), which provides financial support for renewable heating technologies.

The length of time it takes to recoup the cost of a solar hot water tank depends on various factors, such as the cost of energy in the area and the size of the system. However, homeowners can typically expect to recoup their investment within 5-10 years.

Solar hot water tanks require minimal maintenance, but it’s important to have them inspected regularly by a qualified professional. Additionally, homeowners should keep the panels free of debris and monitor the system for any leaks or other issues.

In most cases, planning permission is not required to install a solar hot water tank, but homeowners should always check with their local planning authority to confirm.
