A Tank Monitor that Gives You 100% Confidence
The GREMLIN® Tank Monitor takes the guesswork out of deliveries. It takes ultrasonic readings of the fuel level in your oil tank and sends those readings to our office over the internet. With this precision, we can ensure that you get exactly the fuel you need, when

you need it. We want you to be 100% CONFIDENT you will not run out of fuel and give you a greater connection to your comfort.

Access to Your Tank Level and Delivery Information – All from Your Phone or Tablet
The GREMLIN® App gives you instant access to information you never had before. You’ll be able to see how much fuel you have in your tank, any time, from anywhere. You’ll see how much you’ve been using and approximately when your next delivery is scheduled. You’ll be able to call or email us, or go to our website, just by tapping an icon on your smartphone or tablet.

How is the Tank Monitor Installed?
The installation is done by our technicians in just a few minutes. Our technician attaches the tank monitor to your tank and connects it to either your home Wifi or a cellular network, depending on the model. The sooner you have a GREMLIN® guarding your tank, the more confident you’ll be.
