The WWHR Evolution – Ignoring domestic hot water risks the future of affordable and efficient homes
A three-part webinar series from Showersave
As homes become increasingly electrified, domestic hot water (DHW) is becoming a bigger part of the energy equation. But are we doing enough to reduce demand before investing in additional energy supply?
In this three-part webinar series, Showersave brings together industry experts, specifiers and developers to explore the often-overlooked role of domestic hot water and shower waste water heat recovery (WWHR) in future home design.
Across three sessions, we will look at the data, challenge conventional approaches and share practical examples of how reducing DHW demand can support more efficient heat pump systems, smaller cylinder requirements, reduced pressure on the electricity grid and lower energy bills for residents.
What will you take away?
- Understand the whole-house design and financial benefits of specifying WWHR.
- Explore the relationship between DHW demand, heat pump efficiency and cylinder sizing.
- Understand how reducing hot water demand can help manage peak electricity demand as homes become increasingly electrified.
- Hear from industry professionals about real-world projects, energy performance and resident experience.
- Gain practical insights to help inform your future development and specification decisions.
Session 1: Big efficiency, real data. Waste water heat recovery, the reality
Friday 27 November | 12:00–12:45
Speakers: Tony Gordon, Managing Director & Alex Parkinson, Sales Director, Showersave
Tony Gordon
Alex Parkinson
Tony’s expertise in sustainable technology drives his passion to advancing awareness and adoption of WWHR, helping clients reduce energy consumption and lower their environmental footprint.
Alex has over 20 years of experience in the HVAC, renewables and energy saving technology sectors, giving him a strong blend of technical understanding and commercial focus.
What can 20 years of experience recovering wasted shower water energy teach us about designing better homes?
Tony and Alex will take a look at Showersave’s work with the housing market, bringing together research, white papers, reports, practical findings and collaboration data to explore what the industry has learned about WWHR.
The session will also look at how WWHR works alongside technologies including air source heat pumps, PV and hot water cylinders.
The takeaway: Discover how reducing baseline DHW demand can support smarter and more efficient energy design for future homes.
Session 2: Electrify smarter — Reduce hot water demand before scaling supply
Thursday 10 December | 12:00–12:45
Speakers: James Major, Founder & Director, Hubb Innovations Ltd & Tony Gordon, Managing Director, Showersave
James Major
Tony Gordon
James is Founder and Director of Hubb Innovations and creator of HubbPro, a digital platform helping housebuilders make informed decisions about energy and building services.
With a background in building services engineering, James works with developers to assess heating, hot water, electricity demand, solar PV, EV charging and grid connections, focusing on cost, capacity and development viability.
Through HubbPro, he turns complex technical analysis into practical tools, helping teams compare options and make better-informed decisions early in the design process. James believes good engineering starts with the right questions: what does a development actually need, what will it cost, and can each decision be justified?
As the industry moves towards electrification, how can we make heat pump systems work harder and more efficiently?
James and Tony will examine the relationship between DHW demand and the design of electrified homes, exploring how reducing hot water demand can optimise heat pump performance and potentially reduce cylinder sizing requirements.
The takeaway: Understand why reducing demand should be considered alongside increasing energy supply when designing efficient future homes.
Session 3: The winning formula — Efficient heat pumps & satisfied residents
Thursday 14 January 2027 | 12:00–12:45
Speakers: Jaimie Wragg, Managing Director, Matthew Homes & Gary Nicholls, Executive Chair, Briary Energy
Jaimie Wragg
Gary Nicholls
Jaimie has over 30 years’ experience in the housebuilding industry, spanning design, planning, technical delivery and business management. Since 2019, he has been Managing Director of Matthew Homes Limited, overseeing the business’s strategic direction and day-to-day operations.
Previously, Jaimie spent over eight years as Design & Technical Director at Bloor Homes Eastern, alongside senior roles at Weston Homes and Abbey Developments. He also ran his own architectural practice.
Passionate about high-quality, sustainable homes, Jaimie believes success comes from combining great design, sound commercial decisions, strong teams and a commitment to creating thriving communities.
What does WWHR look like when it moves from theory into real housing developments?
Jaimie and Gary will share practical experience of deploying Showersave within new developments, looking at the outcomes for housebuilders and, importantly, the people living in the homes.
The session will explore the practical considerations of implementation, energy performance and resident satisfaction.
The takeaway: Hear first-hand how WWHR can form part of an effective whole-house approach to delivering efficient, comfortable and affordable homes.
