How Smart Immersion Heaters Work with Solar PV Systems
The Technology Behind Smart Immersion Heating
Smart immersion heaters rely on current transformers (CTs) to monitor the flow of electricity in your home. These sensors are attached to the main electrical cables, allowing the system to measure the balance between the energy generated by your solar panels and the electricity your household uses. When there’s surplus energy – electricity your home doesn’t need – it’s automatically redirected to your immersion heater.
The system uses Pulse Width Modulation (PWM) to fine-tune the power being sent to the heater, ensuring only the excess energy is used to heat water. For example, if your solar panels produce 1kW of surplus energy, exactly 1kW is sent to your immersion heater, no more, no less.
Temperature sensors in your hot water cylinder work in tandem with the smart controller to prevent overheating. Once the water reaches the desired temperature, typically around 60°C, the system stops diverting energy. This ensures your water is heated efficiently while avoiding waste. Let’s take a look at the key components needed to make this system work seamlessly.
What You Need for Installation
To set up a smart immersion system, you’ll need a few essential components: a solar PV system, a hot water cylinder with a 2-3kW immersion element, and a smart controller equipped with current transformers. Installation must be carried out by a qualified electrician to ensure everything is connected safely and correctly.
For context, EECO Energy offers installations ranging from 4.5kW systems with 10 solar panels (producing approximately 3,380kWh annually) to 9kW systems with 20 panels (generating around 7,099kWh per year).
The immersion element, typically rated between 2kW and 3kW, is well-suited to the output of most household solar PV systems. The smart controller links your solar panels to your immersion heater and is connected to your consumer unit. Proper installation of the current transformers is crucial, and only an electrician with expertise in solar systems should handle this task. Now, let’s explore how these components work together to optimise your energy use.
How Energy Flow Works
During the day, your solar panels generate electricity, which flows into your home’s electrical system. The smart controller constantly monitors this incoming energy against your household’s electricity usage, including appliances, lighting, and other devices. When your solar generation exceeds what your home needs, the surplus energy is redirected to heat water instead of being sent back to the grid at lower export rates.
For example, if a 7.2kW solar system is generating 4kW of electricity and your household is consuming 1.5kW, the remaining 2.5kW is diverted to your immersion heater. The smart controller adjusts this diversion dynamically as your energy generation and consumption fluctuate throughout the day.
The system prioritises your household’s immediate energy needs first. Only when those are met does it redirect leftover energy to heat water. Any remaining surplus is then exported to the grid. This ensures your solar energy is used as efficiently as possible while keeping your home supplied with hot water.
