Solar Thermal

We install Solar Thermal Panels in Exeter and Exmouth. Solar thermal is a clean, green way of providing energy to homes, solar thermal water heating and panel installation is becoming more and more common across Exeter, Exmouth and the wider Devon area. More and more homes and businesses are choosing to harness solar power to heat the water in their homes, and 4 Seasons' team of experts is on hand to help you do just that.

Solar Thermal Water Heating Explained

Solar thermal water heating systems use a network of solar thermal panels installed on your roof to heat water for use throughout your home. This reduces the amount of energy needed to run your boiler or heating, and creates an energy surplus during the summer months.

This surplus can then be sold back to the national grid to offset the initial installation costs of your solar thermal system.

Along with cutting back on fuel costs and reducing your environmental impact, a solar thermal water heating system will also save you money in the long run thanks to its low maintenance and servicing costs.

We make use of tried and tested components which dovetail seamlessly with your existing heating systems. These components are hard-working, hard-wearing and only need a check-up every five years. Plus, because solar thermal panels will be doing your boiler's work throughout the summer months, you'll reduce your boiler's workload, extending its lifespan and reducing costs even further.

This is enough storage to power the average household all night.


Intelligent Hot Water

Intellypower activates electrical appliances automatically when your solar PV installation is generating. This system monitors your energy consumption helping you to reduce your energy bills. They can be retro-fitted to solar PV installations and as they are wireless it means there is minimal disruption.

Intelligent hot water systems utilise the energy generated by your solar PV installation rather than it being exported back to the grid. The in-house display gathers information from the generation meter and uses this information to activate the SmartSwitch to power the immersion tank. The SmartSwitch is retro fitted to the heating element and works on a wireless relay.

ImmerSUN System

ImmerSUN is the Leading PV Water Heating, Solar Hot Water Switch and Controller Supplier in the UK.

The immerSUN monitors the electricity which is about to be exported to the grid and diverts it to the immersion heater. It then automatically directs any excess generated electricity, not used by the house, to the immersion heater in the hot water cylinder.

If the load from the house increases, eg. the washing machine is turned on, the immerSUN will reduce the amount sent to heat water to help you maintain independence from the grid.



ImmerSUN's Key Benefits:

  • Heats water from your PV system or Wind Turbine
  • Effectively adjusts power levels to the immersion heater, keeping the exported power at virtually zero
  • The consumer no longer needs to be at home to use the free electricity, whatever the weather
  • No need to change the immersion heater
  • Suitable for all electrical microgeneration systems
  • Built-in hot water boost timer
  • Manual hot water boost function
  • LCD display shows energy saved, output power and operating mode
  • Dual immersion heater control option
  • Internal multi-function relay in-addition to the modulated power output
  • Up to 4 devices can be daisy-chained for master / slave operation
  • MODBUS RS485 interface for system expansion and external data logging
  • Internal thermal protection
  • 3 year product warranty
  • 4 Seasons Solutions are authorised immerSUN installers.
