Tired of guessing? 

Throwing parts at problems? Stumped by heat pumps? You're not alone. 

This is where is starts to make sense.

The missing foundation

Every heating system runs on the same rules, but most engineers were never taught how they fit together.

Without that foundation, you’re left chasing symptoms and missing the real cause.

This ebook joins everything up, making the system easier to understand as a whole.

What's inside?

This ebook is your first clear step into whole-system thinking. 

It doesn’t try to teach you everything. It introduces the core ideas, shows how they connect and prepares you for the next step.

• The three rules behind boiler and heat pump systems
• How those rules connect
• What changes when you move to heat pumps
• Building regulation requirements
• The pump's real role in the system
• Putting theory to work
