EndoTherm – Energy Saving & Carbon Emission Reducing Hydronic Heating System Additive
EndoTherm is a unique, multi-award winning energy saving hydronic additive independently proven to save up to 15% on space heating energy consumption.
Systems Heat Up Quicker…
Improved Heat Transfer…
Using Less Energy!
EndoTherm has been rigourously tested with savings confirmed by multiple third party Research & Development laboratories and facilities.
Easy to Install
EndoTherm requires no system downtime and can be installed, like an inhibitor, in just 10-15 minutes.
Non - Corrosive
Award Winning & Recognised
Carbon Emission Reduction
As EndoTherm reduces heating energy consumption, greenhouse gas emissions are also reduced which is vital to achieve net zero targets.
Laboratory testing, and studies carried out in samples of domestic and non-domestic properties, shows that EndoTherm has been effective in reducing energy and fuel consumption with condensing boilers *
EndoTherm has confirmed compatibility with these major boiler manufacturers:
*EndoTherm does not invalidate the warranties of these boiler manufacturers

Alexandra Tudose, Manager, Energy & Environmental Sustainability.
Maple Ridge School District - British Columbia, Canada.
“SD42 decided to move ahead with the EndoTherm treatment at three of our elementary schools in early 2021. We were in the middle of the COVID-19 pandemic when SD42 rolled out a number of ventilation improvements in all of our schools, that ultimately resulted in a natural gas consumption spike.
Despite this, using EndoTherm in the three schools shows a reduction in our natural gas consumption that resulted in a payback within the 16 month pilot period.”
Andrew Hogg, Energy Specialist.
Interior Health - British Columbia, Canada.
“Interior Health decided to pursue and verify the EndoTherm additive at three of our facilities in the hopes to see the projected savings as described in previous reports. The results have been positive and on average the savings exceeded expectations, with a payback within one year.
Based on these results, further implementation will be considered at other Interior Health sites to help achieve our energy goals.”
Jon Arroyo, Energy Manager.
Rhondda Cynon Taf County Borough Council.
“Rhondda Cynon Taf County Borough Council have tried a few test cases looking at EndoTherm. We added EndoTherm into a variety of buildings with no other changes. We have discovered that radiators reported as hotter (from people unaware of what we have done) and a reduction in consumption between 12-21%.”
Kent Rochon, General Manager.
“BGIS introduced EndoTherm into the hydronic system of one of our client’s buildings in the fall of 2018.
After reviewing utility usage after one year we were very pleased to see a reduction of boiler natural gas consumption usage by 14% with resulting savings of $3,836. Due to the success of this pilot project BGIS will proceed with introducing EndoTherm into other buildings within our clients portfolio.”
Stephen Vaughan, Energy Manager.
“The (EndoTherm) project certainly hasn’t disappointed, installation was extremely simple and savings have by far exceeded our initial expectations. The installation at Lingley Mere has been a huge success and is continuing to realise savings month on month.”
Lindsey Tourand- P.Eng, CEM, Manager, Technical Services.
Bentall Kennedy (Canada) LP.
“After fact checking reviews and technical due diligence, we decided to pilot the use of EndoTherm at one of our Calgary properties. The property had an ASHRAE Level 1 Energy audit, monthly trend data for benchmarking, and no other recent energy conservation measures in place.
We were happy to confirm 21% fuel savings after the EndoTherm treatment. Based on my experience with both the product and the group supporting it, I would readily recommend EndoTherm to any property manager interested in reducing both operating costs and environmental impact at their buildings.”
R D Bates, Director (Estates & Facilities)
“The EndoTherm project certainly hasn’t disappointed, installation was extremely simple, after monitoring the performance for just over 1 year the saving averaged out at 13.6% on heating consumption which also related to a significant reduction in our carbon emissions.
After our pilot and CIBSE approval this has given us the confidence to recommend EndoTherm to other potential users.”
Sadia Afrin, Commissioning Manager, Development and Asset Strategies
“Relatively simple to install and on average shows greater than 5% savings in natural gas for space heating. This contributes to reduce associated energy cost and GHG savings from our buildings. The pilot was successful… and can be used in other social housing projects.”
James Page, Hotel Director.
The Wentbridge House Hotel, Restaurant & Brasserie.
“I’m delighted with the results we’re seeing with EndoTherm in such a short period of time. The product has delivered greater savings than expected and combined with the ease of installation, it made the decision to purchase the product a very successful one. Thank you”
Steve Hoover & Patricia Weise Hoover, Owners.
“Historically the temperature was staying around one degree lower than what the system called for at nights. Within two days after installing the EndoTherm we noticed that the temperature was reading within 0.1°C of the temperature requested from the heating system.”
Mike Mamo, Director of Facilities.
East Irondequoit CSD
“Our water treatment provider introduced us to a product called EndoTherm. I was intrigued by the energy savings so I was interested in giving this a try. EndoTherm was installed easily and without any downtime to our system and has shown no negative affects to the inhibitor in our system. The energy saving was significant even though we were not using the school as we normally would have due to the COVID Pandemic.”
The Rotherham NHS Foundation Trust.
"EndoTherm has been added to heating systems in 2 of our smaller properties for approx 2 years. The gas savings realised have been of the order of 10-13.5%"
Blair McFarlane, Energy Manager.
University of the Fraser Valley.
"EndoTherm was installed into our Abbotsford and Chilliwack campus buildings in early 2018 showing a significant reduction in compensated natural gas consumption on site. We expect a return on investment in less than 18 months."
Munish Datta, Head of Plan A and Facilities Management
Marks & Spencer.
“We are now working with the winning product, EndoTherm”
John Murray, Chief Engineer
Northeastern Illinois University.
“One of the many reasons we decided to use EndoTherm was the zero retrofit costs. We simply installed EndoTherm directly into your system and the savings began to accrue. NEIU also saved 300,000lbs of CO2e. It’s pretty good that you put something in, then you get results and so quickly too.”
Jayson Troupe, Facilities Manager.
Borough of Lansdale.
“The process of installing EndoTherm went smoothly with no interruption to the normal function of our building. Our goal is to save on energy costs and reduce our carbon footprint as much as we can. Thanks again for helping us reach a 12.5% savings on our natural gas usage!”
Travis Vilac, Energy Specialist
Simon Fraser University.
“The Simon Fraser University is happy with the results of the pilot. We were eager to see if the product lived up to the hype. The data shows that energy savings were achieved after Endotherm was added. The installation was straight forward and performed by a trained technician.”
Chesterfield NHS Foundation Trust.
“Another Success for the Product EndoTherm”
"The Trials with EndoTherm in our boilers have been very impressive. We have noted less circulating noise and better conductivity. We will install EndoTherm into any central heating systems we install in the future."
"The trial of EndoTherm at our head office has demonstrated a saving of 33% compared with the same period last year. Consideration is now being given to implementing EndoTherm into larger sites."
Health Care Group.
"EndoTherm was installed into one of our properties and within days the boiler had to be turned down to compensate for increased performance. Overall consumption had been reduced by 15.6%."
