World-Leading CAPTIVE ENERGY
Heat Recovery Water Heaters
Our world-leading Captive Energy Heat Recovery Systems capture waste heat from AC chillers, district energy, geothermal, or ambient air, and utilize that energy to provide 100% of a buildings hot water needs; for domestic use, space heating, pools and hot tubs.
Effectively our technologies replace the function of a gas-fired water heater.
Our technologies are compact and modular enough to easily retrofit into existing facilities. Most importantly, we offer our heat recovery systems based on a service-utility model, so there are no capital expenditures on your part.

We installed Green Matters Technologies CE-K500 heat recovery system in our hotel, Real InterContinental Santo Domingo in July 2025.
The experience so far, has been excellent. The installation went smoothly and since then, all hot water for the guest rooms is provided by the system, without the use of our older gas boilers.
I can abide for the system, as it has been a win on every level: happier guests and, a more sustainable operation. I would definitely recommend this solution to any hotel looking to upgrade their hot water system.

We're an
Easy fit
Our Captive Energy Heat Recovery Systems are designed to be seamlessly integrated with any existing air conditioning or chiller unit. It can be easily retrofitted into any legacy system and does not require the removal or replacement of existing boilers.
A SERVICE PRICING MODEL
BASED ON WHAT YOU SAVE
Just as our technology is innovative and unique, so is our pricing model.
We understand that purchasing additional HVAC infrastructure is not something facility owners have usually budgeted for. And even with the potential of new technology providing significant savings, capital expenditures must still be carefully considered.
So we provide our Captive Energy Heat Recovery Systems based on a service-utility model and simply charge a monthly fee based on the savings generated.
It’s a model that ensures what’s best for you, is best for us. The more robust and efficient our technology is, the more you save.
By utilizing heat that would have simply been wasted, our heat recovery systems provide commercial and residential facilities an efficient, cost-effective, energy-saving and emission-free green solution.

a better world
for everyone
Our innovative technologies provide energy-efficient solutions that minimize environmental impact and reduce your energy costs. In fact, our Captive Energy Heat Recovery Systems are one of the most energy-efficient heat recovery systems in the world. That’s why our technologies are in high demand for Net Zero Energy projects.
But we are much more than a green HVAC manufacturer.
While we are building the foundation of our business on our patented energy recovery systems, additional products that are in the design pipeline include flow metering, solar enrichment, and redux-flow battery systems.
Because when it comes to making this world a better place, green matters.
