An Interview with Peter Mortimer – Sales Manager, Showersave

peter mortimerIn our new interview series, we talk to industry-leading product providers to learn more about their roles, changes in the industry and hot topics in the field.

In our first interview, we talk to Peter Mortimer, Sales Manager at Showersave. Peter targets new build residential, social housing refurbishment and all non-residential buildings with multiple showers.

So, Showersave is a services item, how sustainable are they?

Showersave is a very sustainable product. It recovers a large percentage of the energy in the warm wastewater being thrown down the drain. Then at the “end of life,” all the materials used in the construction of Showersave (other than the connection fittings) can be recycled.

What exactly is wastewater heat recovery and how much carbon does it save?

Waste Water Heat Recovery is the capture of the residual energy contained in the waste shower water being thrown down the drain. In simple terms, it is a counter flow heat exchanger that uses the warm waste to pre-heat the incoming cold water and typically saves between 200 – 300 kg CO₂ per year. This will, of course, depend on the number of occupants and frequency/duration of showering that takes place, but to a family home, this is a beneficial improvement.

I understand your products are manufactured in Holland, who is the team there, and how do they help in developing your products?

We have a small manufacturing team of 8 people in Holland headed up by Harry Muller. It is a very stable workforce which means that we have built up a great deal of experience since the first units were made in 2008.

Is Showersave classed as a renewable and if so, when did this classification change from low carbon technology?

Yes. When the Renewable Energy Directive REDII was republished in December 2018, the recovery of energy from wastewater was classified as a Renewable technology.

What does ‘WRAS approved’ mean, and is it maintenance free? What does that mean in terms of importance to both builder/developer and homeowner?

WRAS (Water Regulation Advisory Service) is an important aspect of the credibility of Showersave. Developers invariable aim to install WRAS approved products because this can be an important issue with the NHBC insurance cover on a new build. It is worth noting that not all WWHR systems are WRAS approved, so by having this important recognition, an installer can be confident about Showersave.

Careful design has meant that most Showersave systems work with just gravity and water pressure. This means there are no moving parts and so minimal maintenance is required. The Showersave units sit, “buried” in the fabric of the building, delivering energy efficiency year after year. To an HA or PRS scheme, this zero cost of ownership can be a strong financial consideration.

Are all Waste Water Heat Recovery systems manufactured from copper? Why do you use this material?

Not all WWHR systems are manufactured exclusively from copper. However, at Showersave, we believe that the thermal conductivity properties of copper do provide an important operational advantage to our systems. This means that in all categories of WWHR, the Showersave systems are the highest performing units available.

With Domestic Hot Water becoming the focus of Energy use, how do you feel your products will help in meeting compliance for ADL 2020 and the Future Homes Standard?

Showersave WWHR will deliver an import benefit to future home standards. As we build ever-better insulated houses if we do not address the wasted energy being thrown down the drain, we will miss an important opportunity. The government aim is to move ever closer to zero carbon homes; at Showersave, we believe that we have a significant contribution to make in achieving this target.

How is your company engaged with BEIS, the BRE and legislation in general?

In 2008 WWHR did not exist in the UK market. So from the outset, Showersave has led the way in engaging with policymakers to establish the criteria by which energy recovery from wastewater can be factored into a building design. Over these 12 years, we have built up a detailed understanding of how energy efficiency technologies are recognised by government agencies within the building regulations.

We appreciate the construction industry is in a delicate position at present, and developers are likely to need to cut build costs, how can Showersave help?

It is not uncommon to find developers have over-specified building designs by incorporating an expensive technology when a simpler, low maintenance solution like Showersave is available and capable of delivering similar benefits to the SAP calculation. Developers aim to deliver a quality product that can provide a family with many years of comfortable accommodation. If Showersave is incorporated into the design, then that house will be simpler to build and more economical to run.

Finally, Peter, is Showersave, a member of any organisations actively involved in addressing the Climate Emergency issues?

Yes, we take every opportunity to engage with industry organisations actively involved with this very important objective. In particular, we view our membership of the Sustainable Energy Association and the good work they do in representing the views of small manufacturers like ourselves as hugely beneficial. Also, we have had an active association with the London Energy Technology Initiative (LETI) which for those that don’t know is a voluntary group of industry professionals that has been successful if feeding information into the Mayor’s office and the impact of building energy standards within the London Plan.

Calor Gas presentation Day at Tottenham Hotspur

Recently, Gary Nicholls presented to a group of 30 developers on the proposed ADL 2020 the changes moving forward to Future Homes 2025 regulations, at Tottenham Hotspur Football Club.

One fact that emerged is that only 2 of the attendees had responded to the consultation document, so Gary was able to take them through the proposed changes, the implications and the value engineered specifications likely to meet Option 1 (20% improvement) or Option 2 (31% improvement).

The team at Calor presented on a number of different elements relating to the current regulations and Bio Fuels for the proposed changes moving forward to Future Homes 2025.

Following the tour and lunch, the attendees were treated to a tour of the £1 billion stadium, which was quite amazing!

If you want to know more about the proposed changes and would like Gary to come and present, please get in touch.

Completions surge at CALA

CALA has seen new home completions rise 46% to 1,677 in the year to the end of June, 526 higher than the previous year.
In a trading update issued today (July 4th), the firm says it is on track to deliver its strategic growth plan as it heads for its fifth consecutive year of record profits. Annual revenue is set to exceed £700 million for the first time, up from £587.1 million last year. This is despite CALA’s private average selling price falling to £497,000 from £538,000 as the firm moves away from the market for £1 million-plus homes.
Private revenue per site per week is up 6% to £271,000 with private sales per site per week up to 0.56 from 0.48.
In issuing the trading statement, the firm took the opportunity to call for “urgent reforms” of the planning system.
“2017 has been another record year for the group,” said CALA ceo Alan Brown. “Our performance for the 12 months to the end of June will see us deliver revenue in excess of £700 million for the first time which is a big step towards our stated aim of delivering an annual capacity of up to 2,500 units and £1 billion of revenue by 2020.
“Following the general election result, we now have a Conservative government with a stated manifesto pledge to build one million new homes by 2020. However, if the UK is to stand any hope of delivering on this aim, urgent reform of the planning system is required to remove the obstructions that are preventing us and other developers from getting on and building the homes the country desperately needs.”

Sustainable building design can benefit from EPDs

ASSA ABLOY has voiced its commitment to creating and promoting Environmental Product Declarations. Universally known as EPDs, these product-specific documents can offer assistance in the design of sustainable buildings.

For ASSA ABLOY, sustainability is a key consideration. Its investment in EPDs, which are yet to be established in the construction industry, demonstrates its commitment to the cause.

Throughout its sustainability journey, the group has invested in over 250 product-specific EPDs. Through its own development of the documents, its hopes to show contractors and architects that EPDs can be used to deliver added value to their construction projects.


Sustainable building design can benefit from EPDsASSA ABLOY’s published EPDs cover a range of access control solutions, including mechanical locksets, door closers, floor springs and multi-point locks.

The company believes that these product declarations will be critical to sustainable building design going forward.
Before publication, all EPDs must be independently researched by a third party, to ensure compliance with ISO 14025 and EN 15804. They can then be verified by Germany’s Institut Bauen und Umwelt (IBU).

These steps ensure that each document offers a high level of detail, which accurately reflects the environmental performance of the product it discusses.
This information can offer architects and contractors a better understanding of a product’s long-term ecological credentials and environmental impact.
For example, a recently published EPD for SMARTair wireless escutcheon details all necessary information: from the embodied carbon of the product, to the impact of carton and foam packaging.

It also discusses the recycling potential of the system’s steel and zinc content.

South Korea set to deploy 36MW energy storage system

Country’s largest utility aims to install 500MW of energy storage capacity to balance supply and demand by the end of 2017

South Korea’s largest utility has contracted battery developers Kokam to build a 36MW energy storage system at its Non-Gong substation in the south of the country.

The agreement, which was announced on Monday, will see the firm install two different lithium ion battery technologies on behalf of Korea Electric Power Corporation (KEPCO) to help balance supply and demand.

Work began on the project in June and is scheduled to be completed by December this year.

In March Kokam completed a new 24MW storage system in the country – currently the world’s largest lithium ion installation for matching supply and demand. Once the newest system is installed, Kokam will have deployed 92MW of energy storage capacity for frequency regulation for KEPCO.

Battery storage systems for frequency regulation enable KEPCO to manage demand on the grid without resorting to spinning power generation reserves – the extra generation capacity available by increasing the power output of existing generators.

The installation will bring KEPCO a step closer to its goal of installing 500MW of energy storage capacity for frequency regulation by the end of 2017.

The announcement is the latest in a series of good news for the nascent global energy storage industry. Just last week Gaelectric revealed it has been awarded an extra €8.3m in EU funding for its novel compressed air energy storage project. Meanwhile a report released last month from market analysts GTM Research predicted that Germany’s energy storage market could reach over £780m by 2021.

scotland wind turbine

Scotland completely powered by weekend wind

Wind power met all of Scotland’s electricity needs on Sunday, new data shows

Blustery weekend weather sent Scottish wind turbines into overdrive on Sunday, with wind energy generating the equivalent of all its electricity needs for the day.

According to data released today by WWF Scotland, wind farms in the country produced 39,545MWh of electricity to the National Grid on Sunday – more than 2,000MWh more than the amount of electricity Scotland consumed that day.

In total, wind turbines generated the equivalent of 106 per cent of Scotland’s entire electricity needs on the day – helped in part by the lower weekend demand for electricity.

It is the first time this year that wind has delivered more than 100 per cent of Scottish electricity needs. However, WeatherEnergy – which collates the wind data for WWF – only began recording wind generation in 2015, so it is possible such an event has happened in previous years, WWF said.

But Laing Banks, director of WWF Scotland, said while the event should be celebrated, if wind is to continue to play an ever greater role in Scotland’s electricity system political support for renewables must continue.

“If we want to ensure we reap the many benefits of becoming a low carbon economy we need to see this political support for renewables continue,” he said in a statement. “We also need the Scottish government’s forthcoming energy strategy to set a goal of securing half of all of our energy, across electricity, heat and transport, from renewables by 2030.”

In related news, earlier this week power demand across the UK’s high-voltage transmission system fell to an 11-year low, as warm summer weather coupled with embedded wind energy depressed demand on the transmission network.

Wind power, which is connected to a distribution network rather than the transmission network, is helping to keep demand for energy from other sources low, Argus Media reported. On Monday morning between 6am and 6.30am, demand on the transmission system dropped to 18.7GW – the lowest in National Grid’s records, which began in April 2005.

Demand for transmission grid power has been falling steadily over recent years. Energy efficiency measures, the growth of renewables and the decline of industrial manufacturing have all contributed to the decline, which has fallen from a high of 46.5GW in February 2006 to an average of 29.1GW in August 2015.
