Palazzetti Ecofire Tiffany Idro V13 TC US: 13 kW slim hydro pellet stove with top coaxial connection

Palazzetti Ecofire Tiffany Idro V13 TC US is a 13 kW sealed, fan-assisted hydro pellet stove designed to heat a central-heating water circuit while also providing direct heat to the installation room.

The TC US – Upper Smoke configuration adds a top coaxial connection for flue-gas evacuation and combustion-air intake.

At rated output the stove delivers up to 12 kW to the heating-water circuit from a total nominal heat output of 13 kW.

With a depth of only 36 cm, Tiffany Idro TC US is particularly suitable for hallways, narrow rooms, passage areas and other space-constrained installations.

13 kW total output and 12 kW to water

When selecting a hydro pellet stove, it is important to distinguish between total useful heat output and the amount of heat actually transferred to the heating-water circuit.

Tiffany Idro V13 TC US provides 13 kW total nominal output, of which approximately 12 kW is transferred to water.

The remaining output contributes to heating the installation room through the appliance body and fan-assisted room heating.

TC US top coaxial connection

The US – Upper Smoke configuration places the chimney connection at the top of the appliance.

The coaxial arrangement allows flue-gas evacuation and combustion-air intake to be integrated into the same upper connection system.

This is especially useful on a slim stove because it helps minimise rear installation space.

The chimney must be designed with components compatible with the certified appliance configuration and installed by qualified personnel.

Slim 36 cm design

Tiffany Idro V13 TC US measures approximately 101 × 36 × 116 cm.

Its exceptionally shallow body makes it suitable for corridors, passage areas and narrow rooms, subject to the manufacturer's required safety clearances.

CC50 sealed combustion: what does it mean?

Tiffany Idro V13 TC US is a CC50 certified sealed pellet stove.

CC50 means that combustion-chamber airtightness is verified at a pressure difference of up to 50 Pa according to EN 16510.

Combustion air can therefore be supplied directly from outdoors instead of being taken from the installation room.

This is particularly relevant in modern well-insulated and low-energy buildings and homes equipped with controlled mechanical ventilation.

Hydro heating with fan-assisted room heating

Tiffany Idro V13 TC US heats the technical water of a compatible central-heating system while also distributing warm air into the room where the stove is installed.

Depending on the hydraulic design, it can be integrated with radiators, fan coils, compatible radiant systems, thermal storage and other heat generators.

Domestic hot-water production requires a separate, correctly designed hydraulic system with a suitable cylinder, storage tank or heat exchanger.

Integrated hydronic unit

The stove includes an integrated hydronic unit designed to simplify connection to the heating system.

The unit includes a circulation pump, safety valve, closed expansion vessel and pressure gauge.

Correct system sizing is still required, including water volume, emitters, temperatures, thermal storage and any additional safety and control components.

Integrated anti-condensation valve

An integrated anti-condensation valve assists correct management of the return-water temperature and helps limit operating conditions that could promote condensation inside the heat exchanger.

Self Cleaning System

Tiffany Idro V13 TC US features Palazzetti's Self Cleaning System.

The system automatically cleans both the pellet burn pot and the heat-exchanger tubes, helping maintain consistent heat transfer and reducing routine manual intervention.

Complete Burning System

The Complete Burning System promotes more complete combustion of residual material, helping reduce ash production and improve fuel utilisation.

Speedy Clean and Balanced Door

The large ash collection drawer and Speedy Clean system simplify routine cleaning operations.

The Balanced Door self-balancing mechanism is designed to maintain correct combustion-chamber closure during temperature changes.

Smart-control compatibility

Tiffany Idro V13 TC US is designed for the optional Universal Gateway, allowing access to compatible Palazzetti app functions.

My Cli-Mate+ and Shape+ require Universal Gateway or MyDisplay+.

Performance and pellet consumption

Tiffany Idro V13 TC US delivers a 13 kW nominal heat output, with approximately 12 kW transferred to water.

The 2027 Palazzetti price list specifies approximately 95% efficiency.

Pellet consumption ranges from approximately 0.91 to 2.82 kg/h, while the hopper holds 30 kg of pellet.

At minimum consumption the theoretical operating time can reach approximately 33 hours. Actual autonomy depends on heat demand, pellet quality and system operating conditions.

Palazzetti Ecofire Tiffany Idro V13 TC US technical specifications

Installation and coaxial chimney system

Tiffany Idro V13 TC US must be connected to a correctly designed hydronic heating system and to a chimney suitable for its certified coaxial configuration.

Palazzetti provides dedicated coaxial adapters for this version. The complete chimney arrangement must be verified by a qualified installer.

A++ energy class, 5-star rating and incentives

Palazzetti Ecofire Tiffany Idro V13 TC US is rated A++ and achieves the Italian 5-star environmental rating under D.M. 186.

Palazzetti documentation refers to Conto Termico for Tiffany Idro V13 TC US. Eligibility for Conto Termico 3.0 depends on the type of project, the appliance being replaced and compliance with all applicable technical and administrative requirements.
