The Energys explainer: How can boiler optimisation improve your efficiency and bottom line?

Increasing the efficiency of existing boiler systems through intelligent controls is a simple and cost-effective way that organisations can save energy, with minimal disruption to operations.

Energys has created a simple explainer, to help you understand the benefits of boiler optimisation and, in so doing, open up valuable cost saving opportunities for your business.

Boiler optimision: The basics

What is it?

In simple terms, boiler optimisers adapt your existing boiler systems to improve the efficiency, without unduly affecting the temperature of your building.

How does it work?

Intelligent boiler controls reduce the number of times a boiler ‘cycles’. This, in turn, reduces the overall ‘burn’ time. By reducing the number of times a boiler fires up, it is possible to reduce the wasted oil or gas due to incomplete burn at start up.

Because intelligent boiler controls simply eliminate a source of energy waste, the temperature of the building is not affected.

Who would benefit?

Intelligent boiler controls are best suited to boilers that are:

  • Floor-standing
  • 50kW or above
  • Gas or oil-fired

This includes:

  • Forced draught burner boilers up to 2MW
  • Two-stage firing boilers (HiLo)

Whether you’re liable under the Carbon Reduction Commitment, aiming to improve your Display Energy Certificate, or racing to meet CO2 targets, boiler controls can help you to reduce your carbon impact. And in all circumstances, burning less fuel saves you money.

Need I worry about installation and disruption?

This is a technology that is fast and simple to implement. Hyde Park Junior and Infant Schools in Plymouth were equipped with four Energys Dynamic Burner Management Units in just a single half day of work.

“There was also the fact that the work could be undertaken while the boilers were live, so there was no need to take them offline for a period,” notes School Bursar Stella Copping. “The result was an installation that entailed no disruption in the short term, but which promises to deliver substantial benefits for our schools over the long run.”

Energys Group can deliver full ‘turnkey’ solutions covering installation, maintenance, monitoring and support, including supply and installation as a single package. In addition, we offer a 5 year warranty on both the product and installation.

What are my funding options?

Public sector

Energy efficiency funding, like the Salix scheme, is available to help increase the efficiency of existing boilers. Energys offers a public sector leasing scheme in partnership with Utility Rentals which requires no upfront capital outlay.

Private sector

The Energys Pay to Save scheme is a new offering from Energys Group, where your energy savings fund the project.

It is designed to help you avoid any need for capital investment and enables you to accelerate your path to a lower carbon footprint. Each agreement is individually negotiated with you and allows for a degree of tailoring to meet your organisation’s particular needs.

The final word on payback

The upward trend of fuel prices is likely to continue, but improving the efficiency of your boiler can secure ongoing savings on your fuel bills. As a result, payback on intelligent boiler controls is normally achieved in less than two years.

Energys boiler optimisation case studies

Organisations of different sectors and sizes are reaping the benefits of boiler optimisation technology. Testament to this success are our case studies, which illustrate the true opportunities real world installation provides.

Hyde Park Junior and Infant Schools

Through a leasing arrangement with Utility Rentals, for Energys Dynamic Burner Management Units, this school has achieved annual energy savings of 15%, some 9.45 tonnes of CO2 saving, with a 2.5 year payback.

Avon & Somerset Constabulary

The Avon & Somerset Constabulary has made impressive savings in gas consumption across 10 of its locations, thanks to patented boiler optimisation technology from Energys.

Avon and Somerset Constabulary is achieving annual savings in gas of 14-25%, averaging 18.8% across 10 sites where the units have been installed. Another huge benefit is that the system offers a remote access function, ensuring immediate and comprehensive visibility with regard to gas consumption and savings.

New MEES guidance promises vast improvements for energy efficiency in commercial buildings

In recent weeks, industry magazine The Energyst has reported:

‘The government has published guidance for landlords on the new regulations that could prevent them from renting buildings to tenants if they fail to meet minimum energy efficiency standards.’

It’s a crucial development. The Minimum Energy Efficiency Standards (MEES) come into force in April 2018. But preparatory action now is needed, both to understand MEES implications and get ready for potential remedial works.

The minimum level of energy efficiency provisions will mean that, subject to certain requirements and exemptions:

a) from 1 April 2018, landlords of non-domestic private rented properties (including public sector landlords) may not grant a tenancy to new or existing tenants if their property has an EPC rating of band F or G (shown on a valid Energy Performance Certificate for the property).

b) from 1 April 2023, landlords must not continue letting a non-domestic property which is already let if that property has an EPC rating of band F or G.

This means some 1 in 5 UK commercial buildings would fail the MEES test, and the maximum fine for failure to comply with MEES stands at £160,000 per property.

Therefore, it’s critical that landlords across the UK take notice, right now, of the implications. When implemented well, MEES stand to make UK property substantially more sustainable, and improve the quality of rented space for tenants.

Reputational benefit, longer term tenants and a more profitable portfolio are among the wins for landlords. But to reap such rewards, the sector as a whole must react promptly to what MEES will mean.

What does the guidance say?

The guidance sets out, via a number of flowcharts, the decision process whereby landlords can judge whether a property can legally be let under MEES regs. It also details the MEES laws in depth.

This alone is useful. UK environmental legislation is complex. Pathways to help landlords examine their responsibilities, and set about meeting them are most welcome.

“We recommend that every UK commercial landlord consults the MEES guidance immediately,” explains Kevin Cox, Managing Director, Energys Group.

“It’s vital to do this for a number of reasons. Firstly, you need to comply. You need to plan out any costs, and the timeline of getting energy efficiency in your buildings up to standard.

“All of these elements will affect your business, your profit, your planning and your tenants. Often, the response to rules like MEES is to hide one’s head in the sand.

“That simply won’t wash in this case. MEES are here, and it’s essential to comply. There are huge benefits for landlords who do. You can win new business, based on your reputation as a sustainable letting agent.

“You will hold tenants for longer, who prefer the more comfortable heating and cooling systems in your sustainable, intelligently managed buildings. You will be ahead of the game; an example of futureproof, modern business.

“And of course, you will save money on potential fines, while your energy efficient buildings will command higher rents than the competition.”

Salix announces new energy efficiency funding for Academies, MATs and Sixth Form Colleges

Salix has developed a new fund in partnership with the Education Funding Agency (EFA) that focuses specifically on energy efficiency projects.

The Salix Energy Efficiency Fund (SEEF) is available for all academies, including those in large Multi-Academy Trusts (MATs) as well as sixth form colleges (SFC).

The fund is directed to those academies and SFCs that have energy efficiency projects that need capital to invest to save but may not meet the Condition Improvement Fund’s (CIF) condition need criteria.

This could include projects such as lighting or heating controls, LED lighting, insulation or boiler/heating system upgrades

Energys Group has helped many schools and colleges successfully apply for Salix funding, such as Hackney Community College, which is saving 320 tonnes of CO2 a year as a result of Salix-funded upgrades. We can support you through every step of the process, from application through to installation.

For more information on the fund, visit the Salix website; or contact Energys Group to learn more about how we can help.

LED lighting for factories; a facility manager’s guide

For professionals wondering how to save energy in factories, retrofit LED solutions will deliver and perform better than legacy solutions. But choosing the best, well considered options and specifications depends on your exact scenario

The Carbon Trust says lighting typically consumes 20% of the electricity used in commercial and industrial buildings.

In these times of high energy prices, finding cost-effective ways to reduce levels of electricity consumed by lighting can deliver appreciable long-term reductions on business electricity bills.

But there is more to delivering sustainable solutions than picking the first LED that springs to mind.

Metal halide and industrial lighting; why bespoke knowledge makes better business sense

One Energys client, Parker Hannifin, has set a corporate objective of a 5% energy reduction per annum. EHSE & Facilities Manager Tony Woodward realised that one of the best ways to achieve this goal would be to phase out old metal halide lamps in favour of next-generation LEDs.

An estimated energy saving of at least £36,423 per annum helped convince Mr Woodward’s superiors LED replacements were the way to go. But the story wasn’t that simple.

“The fact is, I had looked at metal halide replacements in the past, but had not been able to find anything good enough,” he recalls. “But then I came across the Energys lamps. For a start, they offer the right colour temperature, an absolutely crucial requirement and one lacking from previous products I’d seen.

“An added benefit is they also have in-built fans to keep them cool. A test involving eight products further underlined my opinion of their excellent light quality.”

Consistency of light quality was a particular preoccupation for Tony, who was keen to ensure the required illumination throughout the manufacturing shopfloor.

The fixtures’ contribution to reducing radiant heat was another significant benefit; particularly given the firm’s aim of enhancing its healthy working environments by minimising staff fatigue.

The details prove an important point; LEDs are good, but you still need to do your homework. Picking the best supplier, like Energys, will deliver bespoke solutions that fit your precise needs.

Additional benefits of LED vs sodium SONs

Every factory is different, so every facilities manager must seek the right LED technology to suit the legacy replacements needed.

In the example of facilities using sodium SONs, Energys LEDs ranging from 20W to 100W will effectively replace SONs ranging from 70W up to 400W.

LED lighting upgrade achieves up to 75% energy savings for courier company

Energys Group’s range of New Vision energy efficient LED fixtures have been chosen to replace the existing high output fluorescent and metal halide fittings at Prompto Despatch in Cork, Ireland. The new fittings offer a highly energy efficient LED solution coupled with a 14-month payback.

With an extensive fleet of modern vehicles and state-of-the-art warehousing facilities, Prompto Despatch Ltd has steadily developed into one of the most efficient delivery services in Ireland since its foundation in 1986.

Following an audit and assessment of the existing lighting by Impact Energy Solutions, it was obvious from a detailed lighting report that the time was right to upgrade all current fluorescent, metal halide and SON lighting to an LED solution.

Office space

The office facility was previously equipped with standard 600×600 T8 fluorescent luminaires. Each fitting had 4x18W T8 fluorescent lamps (=108W including the ballast). Impact Energy Solutions suggested replacement of these fittings with New Vision 36W LED panels, resulting in improvements in light output coupled with immediate energy savings in excess of +65%.

Warehouse space

Even greater savings have been achieved in the warehouse space. Prompto’s 400W M/H lamps (=456W including ballast) were retrofitted with New Vision’s ‘plug & play’ 80W LED SON lamps, achieving instant energy savings of +75%.

External and internal floodlights

All external & internal 250W & 400W M/H floodlights have been replaced with New Vision’s 80W & 100W LED Floodlights, resulting in energy savings of +70% and a step-change improvement in light quality and output.


The shrewd decision to switch to New Vision LED technology has had an immediate and positive impact on the company’s bottom line thanks to a reduction in lighting energy costs by +60%, plus virtually zero requirement for maintenance.

The New Vision products also offer further piece of mind thanks to a guaranteed 5 year manufacturer’s warranty.

What the customer says:

“It was obvious from the outset that as soon as the New Vision LED lighting was installed we had made the right decision, with much improved lighting levels and instantly reduced energy costs.

“Impact Energy Solutions followed this up, by submitting and securing a Carbon Credit Rebate on our behalf for the LED lighting upgrade project. Apart from reducing our energy costs by more than 60%, we are delighted Prompto Despatch Ltd. is playing its part in reducing our national CO2 emissions.”

James Delea, Managing Director Prompto Despatch Ltd.
