SAV and Insite launch the UK’s first digital smart metering App for heat networks

November 25, 2019

SAV Systems and Insite Energy have joined forces to launch KURVE, the market’s first digital smart metering app for heat networks.

Designed for use by both heat network operators and consumers, KURVE has the potential to deliver 62% savings in capital expenditure and 53% savings in operational costs. Heat network operators specifying KURVE will gain remote access to data diagnostics including energy consumption and VWART (Volume Weighted Average Return Temperature) from each connected meter, using the system’s wired Smart M-Bus infrastructure.

Analysis of this data provides insight into usage patterns and enables heat network operators to optimise network performance, a functionality that hitherto was only available with expensive, pre-payment metering solutions.

At the same time, KURVE shows users their energy consumption for the day, week, month and year, giving them access to this data whenever they want, via any internet-connected device. This visibility promotes their engagement with the system and their energy usage – a proven way of encouraging reduced energy use. Payments can be made securely via PayPoint through the KURVE App, in any PayPoint outlet, or over the phone.

Consequently, KURVE provides full compliance with increasingly stringent metering and billing regulations imposed by the Energy Efficiency Directive. This Directive requires all new meters to be remotely readable from October 2020, with data being available to customers on at least a monthly basis by 2027.

KURVE is a streamlined package which combines a Kamstrup energy meter, prepayment valve and Kamstrup MASTER, with a heat interface unit (HIU) from SAV or other provider. KURVE equipment is pre-wired and does not require an in-home display (IHD) device. KURVE’s design not only cuts down time spent on installation and validation of commissioning, it also significantly reduces service, maintenance and administration costs compared to PAYG alternatives.

“SAV has been working with designers, manufacturers and heat network operators for many years, finding increasingly innovative ways to optimise heat network efficiency and data visibility. Providing digital metering and billing solutions will deliver significant benefits for heat network operators such as housing associations, local authorities, developers and managing agents – as well as their customers. This functionality is something that our clients have been requesting for some time. By combining our experience of heat networks and application of new technologies with Insite’s billing and metering expertise, we have developed KURVE as our response to that feedback.”

Jan Hansen, Director SAV Systems

“KURVE also addresses the very topical concerns around managing debt risk and reducing customer heat tariffs. With the Competition & Markets Authority (CMA) calling for heat networks to be regulated, there has never been a better time for network providers to introduce greater levels of transparency and encourage positive consumer engagement.”

Anthony Coates-Smith, Managing Director Insite Energy
