This path separates two decisions that are often mixed together: choosing the right SWH technology and choosing the right size. By handling these in sequence, you can compare systems more clearly and avoid sizing a setup that is poorly matched to your site conditions.
Who This Path Is For
Use this path if you are planning a solar water heating installation and want a clear understanding of collector types, tank sizing logic, and pressure/water-quality considerations before requesting a final quote.
What You'll Learn
- How flat plate and evacuated tube systems compare in different conditions
- Why tank size alone does not determine SWH performance
- How usage profile, pressure, and water quality affect system selection
- What FAQs/glossary terms to review before discussing final sizing
Recommended Sequence
SWH Comparison: Flat Plate vs. Tubes
Start with technology selection so you understand what each collector type is best suited for before talking about tank size.
Solar Water Heating Sizing Basics
Use this guide to understand demand profile, tank sizing, collector capacity, and the site factors that affect hot-water performance.
Flat Plate Pressurized Systems (FAQ)
Review the FAQ entry for terminology and practical meaning if this system type is in your shortlist.
Evacuated Tubes / High Efficiency (FAQ)
Use this FAQ to compare how evacuated-tube systems are framed, where they perform well, and what they imply for your shortlist.
If you already know your building type and usage pattern, you can jump to the sizing guide first. Return to the comparison guide when finalizing collector technology.
Next Step
Use the water-heating calculator for a budgetary estimate, then move to the Water Heating service page or contact for site-specific sizing and system selection.
