oh4: brilliant in its simplicity

Reduce the impact heating & cooling has on the environment whilst also saving you money.

It doesn’t have to be complicated to be efficient.

OH4 is proven to reduce energy costs and lower the impact heating & cooling buildings has on the environment.

Our simple, “fit & forget” technology works with ALL closed loop, water-based heating/cooling systems, all we ask is that your system has a degree of control. 

Imagine no disruption, no need for system overhaul and no break in service, with OH4 this is standard!

Are you looking to reduce your bills or reduce your carbon impact?

Our unique energy reduction intervention has been designed to work with you to reduce your energy costs whilst also reducing the impact your heating/cooling is having on the environment. 

The evidence is there for all to see, and our client savings reports will give you a clear understanding of the financial savings you are making as well as your carbon savings so, if you are looking to save money or help save the planet, OH4 does both simultaneously.

The process is simple

We are often asked, “How much OH4 is needed for my boiler/chiller?”

The answer is simple…

We need to know three basic things for us to start to work on a return on investment-based proposal, the three things are…

  • How big is your boiler/chiller?

  • What is the diameter of the thinnest pipework on your closed loop system?

  • How much did you spend on heating/cooling last year?

Click here, answer the questions and we will start working on the numbers for you.

Once we have created an indicative proposal for you, we will arrange a meeting to discuss your needs, goals and aspirations. 

Is OH4 right for my business?

From our experience the answer is probably YES!

OH4 and their partners are continuing to test the capabilities of our technology, and we are proud to say that we have yet to find a business sector or industry type where OH4 hasn’t been able to evidence savings. Industry sectors we have worked with include

  • Hospitality.

  • The Care Sector.

  • Retail. 

  • Data Centres.

We are always open to a challenge, and are constantly striving to understand the art of the possible. Contact us here to see if OH4 is right for your business.

What the headland hotel Said about us

“OH4 carried out work for us at the Headland recently, installing the OH4 Heat Transfer System on our heating and hot water systems, for the main hotel, our Spa, Aqua Centre and most of the cottages on our site. We were delighted with how non-invasive the installation was, with no disruption experienced to the hotel’s operation, working around holiday bookings in the cottages, and scheduled to complete the work in the autumn. The installation was carried out on the main hotel building in April of 2024, and since then we have seen savings of energy usage in excess of 20% measured in kWh per degree, per day, per guest, compared against the previous year, to give truly comparable figures. Steve’s work has been highly professional and efficient, and we are delighted with the savings we have seen already, and those we anticipate are to come. We would highly recommend both Steve and his OH4 system to other hotels and guest accommodation, as the results speak for themselves in terms of energy savings, and the system will be a benefit to the hotel for decades to come.”
