Type B - The B version is suitable to produce DHW when the temperature of the water stored inside the buffer is lower than 58°C, for example when the energy source is a heat pump or a condensing boiler. BR - The BR version is suitable to produce DHW when the temperature of the water stored inside the buffer is lower than 58°C, for example when the energy source is a heat pump or a condensing boiler. BM - The BM version is suitable to produce DHW when the temperature of the water stored inside the buffer tank exceed 58°C, for example when the energy source is biomass boilers, traditional gas boilers, electric heaters, district heating. BMR - The BMR version is suitable to produce DHW when the temperature of the water stored inside the buffer tank exceed 58°C, for example when the energy source is biomass boilers, traditional gas boilers, electric heaters, district heating BD - The BD version is suitable to produce DHW when the temperature of the water stored inside the buffer is lower than 58°C, for example when the energy source is a heat pump or a condensing boiler.

The T-FAST PRO is a module designed for the instantaneous production of domestic hot water (DHW) using a stainless steel brazed plate heat exchanger, which is typically used in combination with buffer storage tanks.

AVAILABLE MODULES -

The BIG T-FAST EVO3 module is available in 8 versions, starting from a B version (basic) it can be implemented with different sets (assembled and tested directly in the factory) depending on the requirements:

• R DHW RECIRCULATION MODULE: intelligent management of DHW recirculation when is need to keep the DHW line warm (time band control and based on the recirculation return temperature).

• M MIXING MODULE: adjusts and stabilizes the inlet temperature of the plate heat exchanger when the temperature of the water stored inside the buffer tank exceeds 58°C.

This facilitates stratification, limits the formation of limescale in the plate heat exchanger, preserves the system's functionality over the time and opti mises the control of the sanitary outlet temperature.

• D DIVERTER MODULE: allows the stratification of both two puffers in series and high stratification buffer tanks.

Benefits

Energy Efficiency: Operates at lower flow temperatures, reducing energy use. For example, cutting flow temperatures from 80°C to 55°C saves up to 12% on gas boilers. Heat pumps see efficiency gains of 150-250% by reducing primary temperatures, dramatically lowering running costs.

Low Carbon Technology Ready: Supports air source heat pumps, ground source heat pumps, electric boilers, and solar PV without requiring system resizing.

Enhanced Legionella Safety: Produces hot water on demand, eliminating secondary water storage and reducing risks of bacteria growth or water stagnation. Compliant with ACOP L8 and HSG274.

Cost Savings: Eliminates the need for stainless steel calorifiers, twin-headed pumps, and tank chlorination, lowering both procurement and maintenance costs.

Extended System Life: Reduced system temperatures lower wear and stress on the heat source, prolonging equipment life and cutting operational costs.

Flexible & Scalable: Cascade multiple units for higher output or future upgrades. Built-in redundancy ensures system reliability, with options for electric immersion heaters for backup or solar PV integration.

Smart Design: Integrated PID controller, 3-port mixing valve, and secondary return pump with sensors ensure precise temperature control and efficient performance.

Double pumps: The adjustment of the flow rate on the primary side through two modulating pumps in parallel ensures a constant DHW supply even in case of a pump fault (up to 60% of the total DHW supply) and guarantees the absolute precision of DHW outlet temperature control even at minimum withdrawal of flow rates. The energy transferred to the cold water flow is only the energy necessary to produce the DHW at the required temperature.

Cascade Kit: Connect several DHW production units in parallel (up to 1200 l/min) with primary temperature of 55°C

Remote Monitoring: with the supervision add on your T-FAST system can be monitored via the web portal, providing real time monitoring and alarm notification.

T-FAST delivers instantaneous hot water with optimal safety, efficiency, and adaptability. It’s the ultimate solution for buildings looking to embrace a low-carbon future while saving on operational and maintenance costs.
