AQ Lite

Bomba de calor retrofit

Air-Source Retrofit System

AQ Lite

AQ Lite is a heat pump retrofit system designed for installation on existing water tanks, making it a highly efficient and cost-effective option for upgrading older installations.

This system ensures that water temperature is maintained at optimal levels throughout the year, regardless of external weather conditions.

0%

More affordable

A great option for obtaining the same functions and benefits offered by a heat pump, but at a more affordable price.

Smart Control

With TST Control Display and EFI SmartApp to control and monitor the operation of the heat pump, both locally and remotely.

Easy Installation

No building work or modifications. Simply connect the heat pump to the water tank using the appropriate hydraulic connections.

Compact and versatile

Thanks to its compact size, the AQ Lite takes up very little space and is easy to install in different areas of the home.

Turn your tank into a heat pump

AQ Lite is designed to modernise domestic hot water (DHW) systems that already have a storage tank. Rather than replacing the entire installation, it allows the existing tank to be utilised and incorporates Air-Source technology to produce hot water more efficiently.

This heat pump extracts thermal energy from the air and transfers it to the water stored in the tank, reducing the amount of electrical energy required to heat it compared to systems based solely on electric heating elements.

This retrofit concept is particularly appealing in homes, where it allows the DHW production system to be upgraded whilst retaining part of the existing plumbing. It is a practical solution for installing a heat pump with minimal disruption and making better use of the components already in place.

Installation

ADAPTED TO DIFFERENT INSTALLATION REQUIREMENTS

The system utilises energy from the outside air and expels the cooled air back outside. To ensure correct operation and compliance with the CTE, it is necessary to channel both the air intake to the unit and the air outlet to the outside.

The system utilises energy from the air inside the home that originates from an unheated area, the size and ventilation conditions of which allow it to be used as an energy source. The cold air is then discharged back into that same area or into another area that meets the appropriate conditions.

The system utilises energy from the air inside the home that comes from an unheated area, whilst the air is expelled to the outside via a duct.
