ModuSat® FS Heat Interface Units with Integrated Tank

Our ModuSat FS range of HIUs provide Indirect high efficiency heating and independent fast recovery hot water via an integrated tank. Units are suitable for both radiator and underfloor heating systems and are well suited to high end apartments and student halls of residence due to the high capacities and back-up stored hot water.

Independent Fast Recovery Hot Water Tanks

Domestic hot water is generated in an unvented cylinder via a high efficiency coil. The primary heat network flows through the heat exchanger coil and transfers the thermal energy to the potable water in the tank.

Preheat times from 10℃ to 60℃ are as low as 12 minutes (for 80 litre model).

Secondary return connection is available on the larger models (200, 300, 400 litres) for constant circulation through the hot water pipes. This is ideal for reduction of hot water response time in larger properties where reaching 50℃ at the tap within 1 minute could otherwise be difficult.

Smart Energy Regulation and Control

Our Smart Energy Regulation and Control provides a myriad of benefits in terms of HIU performance and optimisation of heat network efficiency. So how does it work?

  • Pressure Independent Control Valves (PICV’s) provide integrated differential pressure control, providing balanced, self-configuring flow through the HIU
  • Fast acting, electronically regulated actuators provide immediate response to changes in energy demand
  • Proportional Integral Derivative (PID) control logic provides accurate actuator/valve control and fast response to hot water demand, without “overshoot” (Reduces energy wastage)
  • Electronically actuated PICV’s also function as a shut off valve, so ModuSat® Smart HIU’s can easily be configured for either credit or PAYG billing systems

Control of Two Output Temperatures

ModuSat FS units are able to control two output temperatures, one for the Heating system and another for the Domestic Hot Water tank, a real benefit for Underfloor heating systems.

When in Domestic Hot Water mode, the ModuSat Smart Connected Control will modulate the primary flow ‘up’ to increase output temperature for fast cylinder recovery, but when in heating mode the primary flow will modulate ‘down’ to reduce secondary output temperature.

This is particularly beneficial for Under Floor Heating systems where there is a requirement for lower temperatures and means there is no requirement for a mixing valve or pump set prior to the heating manifold, saving time and money installing additional equipment.

SmartTalk® Communications Network

Electronically controlled units provide many benefits, including the ability to facilitate a 2‐way communication network, which when connected over the internet to remote servers allows our ModuSat® Heat Interface Units to become an IoT device, offering a wide range of benefits to both consumers, facilities managers and heat network operators alike.

  • System can be monitored, adjusted or regulated remotely over the internet using SmartTalk®
  • Full comfort for the end user, whilst also delivering important information regarding the operation of the system
  • Supplied ready to connect to HIVE & NEST controllers
  • Access to granular operational and performance data
  • Open protocol access to meter reading data and alarms

Metering and billing for heat networks Image

Metering and Billing Ready

The Heat Network (Metering & Billing) Regulations (2014) require each resident to be billed individually for the proportion of the total heat they consume from the heat network.

Our ModuSat® units make this easy, featuring an integrated ultrasonic heat meter, which is MID approved with class 2 accuracy (BS EN 1434), ready to connect to a communication network for metering and billing purposes.

In addition, our PaySmart® pre-payment technology is also integrated into each ModuSat® heat interface unit as standard, and – unlike many other pre-payment billing solutions – can easily be activated remotely at any time and requires no additional hardware or infrastructure to set up.

Technical details

ModuSat® FS Storage Range

The Evinox ModuSat® FS heat interface unit has been designed to provide apartments and communal housing developments with high efficiency heating and independent fast recovery hot water.

Consisting of a fast recovery hot water tank and a plate heat exchanger, combined with electronic PID control using Pressure Independent Control Valves (PICVs) with modulating actuators achieving a low primary return temperature as well as providing differential pressure control and flow rate regulation.

Application

The ModuSat® FS unit is designed to operate with Evinox SmartTalk® two-way communication system for remote metering and diagnostics.

Heating

The heating circuit consists of a plate heat exchanger (PHE), PICV, safety relief valve, manometer, flow and return temperature sensors, Wilo PWM circulation pump and expansion vessel. The heating circuit flow temperature is controlled by the modulation of the primary flow rate with the integrated PICV actuator. Weather compensation is applied to the set heating temperature using SmartTalk® 2-way communication. Suitable for radiators, underfloor heating or fan coil units.

Domestic Hot Water

Domestic hot water is generated in an unvented cylinder via a high efficiency coil. The primary heat network flows through the heat exchanger coil and transfers the thermal energy to the potable water in the tank.

General industry guidelines recommend heating the full volume of the cylinder up to 60C for at least one hour per day. This programme can be set up using our ViewSmart or selected third part thermostat suppliers.
