Domestic hot water and water use account for a large percentage of residential energy usage. In commercial buildings, the proportion of energy usage is smaller. However, there may be opportunities to significantly reduce hot water energy usage and achieve valuable overall savings.Â
It might seem that domestic hot water systems are simple, but it requires a reasonably complex level of analysis and knowledge to maximize savings. Without a detailed understanding of hot water systems, you could be missing out on additional savings.
Hot water systems are easy to overlook in an energy audit. They seem straightforward — water goes in, gets heated, comes out. But getting the most out of a domestic hot water system requires a reasonably detailed level of analysis, and without it, you’re almost certainly leaving savings on the table. This energy efficient residential hot water system course gives you the systematic approach to find those savings and make a credible case for acting on them.
This is Part 7 of 8 of the Investment Grade Energy Auditor (IGEA) certification program and is accredited by ESTA (Energy Services and Technology Association). It covers the full scope of domestic hot water energy efficiency — from understanding system types and their characteristics through to preparing a business case for an upgrade.
Domestic hot water and water use account for a significant share of residential energy consumption — and in commercial buildings, while the proportion is smaller, the savings opportunities can still be substantial. Based strictly on the course content, here’s what you’ll work through:
In this Energy Efficient Residential Hot Water System Course, you’ll learn the fundamentals of domestic hot water systems and how to reduce water usage.Â
You’ll learn a systematic process for identifying hot water inefficiencies, how to use a Sankey diagram, and how to apply the energy efficiency hierarchy. The energy efficiency hierarchy helps you identify many opportunities, no matter what type of domestic hot water system.Â
This Fundamentals of Energy Efficient Domestic Hot Water & Water course elaborates on practical concerns and issues associated with domestic hot water upgrades. It then guides you in preparing the business case for a hot water upgrade.
Continuing Education (CE) or Continuing Professional Development (CPD) refers to additional formal learning activities that are required to maintain a professional certification or accreditation.Â
CE or CPD comes in many names but represents the same thing. Here are some of them that may be used in your country:Â
Many of our courses provide Continuing Professional Development credits, points, hours, or units. To learn more about Continuing Education and Continuing Professional Development, please read here.
When you pass all the quizzes in this course, you’ll get a certificate of achievement on course completion, with a QR code that when scanned validates its authenticity. Use this certificate to demonstrate to employees and others your growing sustainability credentials!

Assessing hot water system efficiency starts with understanding the system type — whether it’s storage or instantaneous — and then systematically identifying where energy is being lost through the system, including distribution losses that are easy to miss. This course teaches a structured assessment process using Sankey diagrams and the energy efficiency hierarchy, so you can identify inefficiencies across any hot water system type.
Storage hot water systems heat and store water in a tank, ready for use — which means they’re subject to standby heat losses even when no hot water is being drawn. Instantaneous systems heat water on demand, eliminating standby losses but with different efficiency characteristics under varying flow conditions. This course covers both system types in detail, including how each uses energy and where the savings opportunities typically lie.
Reducing hot water energy consumption involves a combination of reducing heat losses from storage and distribution, optimising system controls and setpoints, reducing water usage at the point of demand, and — where justified — upgrading to a more efficient system type. This course covers all of these approaches in a structured sequence, including how to prioritise them using the energy efficiency hierarchy.
A credible business case for a hot water upgrade requires accurate baseline data, a clear savings estimate supported by calculations, realistic implementation costs, and a return on investment analysis that decision-makers can act on. This course dedicates a full module to business case preparation — so your recommendations don’t just identify the opportunity, they make the financial case for acting on it.
Rainwater harvesting can contribute to water savings by reducing mains water consumption — which in turn reduces the volume of water that needs to be heated. Whether it’s worth pursuing depends on rainfall patterns, storage costs, and the existing water tariff structure. This course covers rainwater as part of a broader water savings opportunity analysis, giving you the tools to assess whether it’s a worthwhile intervention in a given facility.
Yes. This is Part 7 of 8 of the Investment Grade Energy Auditor (IGEA) certification program. It can be taken as a standalone course for anyone looking to build hot water energy efficiency knowledge specifically, but if you’re working toward full IGEA certification, this is the second-to-last course in the sequence before the final industrial systems module
