New Hot Water Association chair to push cylinder energy storage potential

Stephanie Allchurch will use her tenure to test and construct up awareness of the role that drinking water cylinders can engage in to retail store renewable vitality and aid decarbonise households and heating

Stephanie Allchurch has been appointed Chair of the Incredibly hot Drinking water Affiliation (HWA).

Ms Allchurch, who is merchandise growth manager with heating and renewable methods supplier Altecnic, will support lead the HWA’s work to strengthen market benchmarks all over the installation and routine maintenance of sizzling h2o methods in the drive for reduced carbon buildings.

Isaac Occhipinti, director of external affairs for the HWA, stated Ms Allchurch’s appointment reflected her substantial knowledge operating in the sector for decades.

He mentioned: “Stephanie has in excess of 20 years’ working experience in the marketplace, possessing labored for various makers of plumbing and heating controls. She has also been an energetic member of the HWA for more than 10 years, offering technological insight to type the foundation on expectations, legislation, and assistance.”

Ms Allchurch extra that she would aim in the job on the primary problems facing the sector, including the likely use of techniques this sort of as scorching h2o cylinders to give heat storage for households.

She explained: “I am wanting forward to checking out how the HWA can aid form the business position with incredibly hot water storage cylinders to support exhibit the likely within these as ‘batteries’ to further more assist the journey to decarbonisation.”

Previously this year, the HWA developed a report contacting for a rethink of the UK’s heating method by incentivising the set up of new water cylinders in attributes to guide a shift to reduced carbon warmth units.

The introduction of new Incentives to set up drinking water cylinders must be introduced to decrease the value of straight changing existing combi boiler systems with warmth pumps, the affiliation analyze claimed.

These identical devices can also be utilized to store renewable power produced from sources these kinds of as solar PV and offshore wind programs that can then be reused by conclusion end users later on to cut down domestic electricity expenditures, the HWA included.

Association demands national hot water cylinder installation focus

An business report is contacting for up to 18 million new cylinders to be set up throughout England to be certain a smoother changeover to reduced carbon heating methods and far more successful homes

Authorities must assist the set up of millions of new incredibly hot water cylinders in England to greater aid the decarbonisation of domestic heating, the Very hot Water Association (HWA) argues.

The association’s ‘No Position Like Home’ report concludes that authorities initiatives to introduce small carbon heat systems in properties challenges staying undermined by an all round drop in the variety of scorching water cylinders in use.


As approximated 18 million cylinders could be necessary and ought to be backed by governing administration subsidies, the HWA report has argued.

Fewer than 45 per cent of residences in England at present have a incredibly hot drinking water cylinder. This figure is down from 77 for each cent of residences in 2001, in accordance to the association’s report.  It concludes that the acceptance of the combination boiler, which does not have to have a hot h2o retail store, has been a significant driver in this alter in housing inventory heating.

Nonetheless, it will be very important to make sure that there is assist and incentives to introduce new water cylinder systems that can assist decrease the general price of changing these boilers with lower carbon heat above the up coming two decades, the HWA claimed.

Isaac Occhipinti, director of external affairs with the HWA, explained the report known as for additional action to introduce efficient cylinders to residences to let for a variety of distinctive heat methods to be additional quickly mounted across the present-day housing inventory.

He mentioned, “The political target of decarbonising heating has been only on the warmth resource such as boilers and warmth pumps. There has been minor to no concentrate on scorching water cylinders, and recognition for the vital element they participate in in the effective procedure of lower carbon heating. There is also, at the moment untapped potential for them to act as domestic batteries.”

“To decarbonise heating, all British isles properties will want reduced to zero carbon heating. Most, now available, reduced carbon heating alternatives need a incredibly hot h2o cylinder.”

Awareness challenge

A certain concern of the report is that, not only is there a deficiency of hard work to put in productive warm water cylinders in residences, but there is also minimal consciousness about the importance of these new devices can have to guidance renewable vitality storage

Mr Occhipinti reported, “The government must do far more to educate home owners, regional authorities and social landlords on the want for incredibly hot drinking water storage, and owners really should be ready to entry incentives if they desire to substitute their sizzling drinking water cylinder with no stipulation on the form of procedure to be installed only that it is a appropriate substitution. This will also signify that in the upcoming the price of moving to new heating techniques will be lessened.”

“In addition, the strength storage prospective related with the UK’s present-day installed potential of domestic very hot drinking water cylinders is equivalent to our complete fleet of pumped-hydro-electric storage and with just a fraction of this resource it would be achievable to absorb the premier surpluses of renewable power that come up from offshore wind and solar PV.”

Mr Occhipinti extra, “We also will not be ready to choose edge of the latest grid balancing likely of thousands and thousands of sizzling h2o merchants.”

Incentivising cylinders

A core proposal in the HWA’s report is the contact for an incentive plan to fully address the expense of purchasing and setting up high performance cylinders.

It said that the usual charge would be all-around £900 for the cylinder method and an additional £500 for the set up.

However, the HWA reported that these prices would beneath the typical £5000 cap for works included underneath the short-lived Environmentally friendly Houses Grant that was introduced by the Uk authorities in 2020 to incentivise vitality efficiency advancements and warmth pumps installations.

The repot included that cylinders would make certain that the expense of correctly installing devices these as warmth pumps would be minimized.

The conclusions said, “This will eliminate a sizeable barrier to their set up.”
