Heat Interface Units & the Data Network

So, you’ve decided on the appropriate ModuSat heat interface units for your housing development, but what’s the most suitable data network set-up for metering and billing?

Our experience of heat networks has shown that reading energy meter’s remotely is the most straightforward and efficient way of gathering accurate readings.

Typical Network Set-up –

ModuSat® Heat Interface Unit featuring an integrated heat meter in each home
As standard we recommend using a hard-wired BUS, Ethernet or fibre optic network around the development
SmartTalk® Data Logger in plant room collates meter readings and sends data to remote monitoring office via Broadband communication system
Two-way communication network also enables the system in each dwelling to be fully controlled remotely and provides remote diagnostic capability and client support
Lower running costs and more reliability compared to a GPRS wireless network

PaySmart® Pre-payment System

By providing a pre-payment solution, you can put residents in control of their own energy bills, allowing them to pay for energy as they consume it. This removes any possibility of building up unpaid bills or debt.

Our PaySmart® pre-payment system also takes away the burden of collecting money by the Managing Agent or Housing Association and provides residents with flexibility and choice over how they pay for their heating and hot water.

In addition, all Evinox ModuSat® heat interface units feature in-built PaySmart® technology, which can be activated remotely at any time without gaining access to the property, meaning no additional equipment is required.

Metering & Billing Solutions for Non Evinox Equipment

For communal heating schemes that already have heat interface units or meters and a communication network installed, Evinox can provide a fully comprehensive metering & billing solution to work in harmony with the existing set-up.

For example, a building with an existing M-Bus network and individual meters installed can often be accessed via the existing data logger, allowing Evinox to download data for billing. If this is not possible, an Evinox M-Bus data logger can be fitted, which easily connects to the existing network to allow us to provide a full credit account billing service.
