Under The Hood of Heat Pumps | Clade Engineering

Published at : 23 Dec 2025

Clade Engineering takes you behind the scenes of a complete commercial heat pump installation to explore how system design really works in practice. In this on-site walkthrough, TR is joined by one of our senior designers to break down the key engineering decisions that shape performance, efficiency, and reliability.

We look at how the team sized the heat pumps, why R290 was selected as the refrigerant, and how components such as buffer tanks, inverters, reverse-return headers, and burst discs all work together to control flow, safety, and output. We also discuss how the Clade master controller integrates with the BMS, how to manage legacy buildings with complex layouts, and what it takes to design for high electrical demand, including when DNO upgrades are required.

Inside the domestic hot water plant area, we follow the system step-by-step, covering how heat is delivered, how small temperature differentials are avoided, and how the DHW system is controlled in real time.

If you want a practical look at commercial heat pump design from engineers working in the field every day, this video is a must-watch.
