Liberty Connect: payment solution for heat networks

 

Engineered to benefit both the consumer and the heat network operator, Liberty Connect provides usage information for community heating, and payment options for any size of district or community scheme.

Liberty Connect 100 acts as a hub within the home, providing two-way communications with the heat service provider, including tamper detection.

Consumers benefit from a portable multi-function in-home display, Pipit 500, allowing them to monitor and control their energy consumption and costs.

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 

Applications

  • Saving Money

    Pipit’s touchscreen display allows tenants to view their energy usage in real-time, and their consumption history for the previous twelve months.

    Budgeting becomes easier when tenants can see what they are spending. Our smart metering technology puts control and visibility in their hands, so they only pay for what they’ve used. No more estimated readings. No more unexpected bills.

    Saving energy

    Visibility of energy consumption means that tenants can make informed choices about their energy use. Reducing energy consumption in order to save money naturally has a positive effect on long-term energy waste. It’s an eco-step in the right direction.

    Saving Time

    We like to keep things simple, and our smart pre-payment energy solution combines simplicity with effectiveness. Topping up couldn’t be easier for tenants, with our range of pay-as-you-go offerings. They can top-up at a retail outlet, or from the comfort of their own home online, via text or over the phone.
