A simple way to generate hot water using the sun.

## How Solar Thermal Works

Solar collectors capture heat from sunlight.  
→ Heat transferred to water  
→ Stored in cylinder  
→ Used in building ## What it’s Used For

✔ Hot water (primary use)  
✔ Pre-heating systems  
✔ Industrial processes ##  Key Benefits 

Lower energy bills

Carbon reduction (net zero alignment)

Energy price protection

Works with existing systems

## What’s the Difference Between Solar Thermal and Solar PV?

Solar thermal = heat  
Solar PV = electricity ## Where it Works Best

High hot water demand buildings  
Consistent using patterns  ![mountain-top-solar](https://lochinvar.ltd.uk/wp-content/uploads/2026/05/mountain-top-solar.jpg "mountain-top-solar") ##  Get In Touch
