Customer Testimonials

Product success in the words of our customers


“The University of the Fraser Valley is committed to mitigate its negative environmental impact that contributes to climate change and the degradation of the natural environment. With 98% of electricity coming from renewable sources in British Columbia our focus has been on reducing our natural gas consumption.”

“EndoTherm was installed into our Abbotsford and Chilliwack campus buildings in early 2018. As a result, we’ve seen a significant reduction in our natural gas consumption and associated carbon emissions. We’re pleased with our expected 18 month return on investment.”

Blair McFarlane

Energy Manager, Facilities and Project Management, University of the Fraser Valley

“‘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.’”

Alexandra Tudose

Manager, Energy & Environmental Sustainability, Maple Ridge School District

“‘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.’”

Andrew Hogg

Energy Specialist, Interior Health

“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. The University saved $30,000 and only spent $7,000 over the pilot period due to Gehrke Technology Groups monthly financing plan. NEIU also saved 300,000lbs of CO2e. It’s pretty good that you put something in, then you get results and so quickly too.”

John Murray

Chief Engineer, Northeastern Illinois 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.”

Travis Vilac

Energy Specialist, Simon Fraser University

“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 a 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.”

Kent Rochon

General Manager, BGIS

“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.”

Stephen Vaughan

Energy Manager, EMCOR UK

“The system is 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.”

Sadia Afrin

Commissioning Manager, Development and Asset Strategies

“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.”

Steve Hoover & Patricia Weise Hoover

Owners, J&B Greenhouses

“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.”

“Now being tested and CIBSE approved this has given us the confidence to recommend EndoTherm to other potential users.”

R D Bates

Director (Estates & Facilities), Coleg Gwent. UK

“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!”

Facilities Manager, Borough of Lansdale
