Product catalog summary
Introduction
The Winterwarm XR+ series is a non-condensing gas-fired unit air heater designed with a modern aesthetic and compact size, suitable for various environments. It is an upgrade from the standard XR range, featuring a patented heat exchanger and compliance with ErP2021 regulations without needing a condensate drain.

Key Characteristics
  • Compact design with variable air distribution and airlift effect.
  • Modulating premix burner and fan for energy efficiency.
  • Standard stainless steel heat exchanger.
  • Easy installation and modern design.

Functionality
The XR+ heaters can be suspended in multiple positions, allowing for flexible airflow direction. They function as destratification fans when blowing vertically. The modulating burner and fan reduce energy consumption and noise while maintaining comfort by minimizing temperature fluctuations.

Delta T-Control
An advanced control system with two temperature sensors enhances comfort by managing the temperature gradient. This system, combined with the modulating burner and fan, can achieve up to 15% energy savings compared to conventional heaters. The XR+ also offers summer ventilation for continuous air circulation.

Suspension Options
  • Bracket for horizontal or vertical air distribution.
  • Design bracket for multi-directional airflow.
  • Recessed suspension points for conventional mounting.
  • Vertical suspension kit for "H"-section attachment.

Controls
The MultiTherm thermostat, available in Standard and Comfort models, optimizes gradient control and modulates burner and fan speed for optimal energy consumption. It can control up to 8 heaters and offers features like a 7-day program, manual override, and failure diagnosis.

Technical Data
The XR+ series includes models XR 10+ to XR 60+, with varying specifications such as nominal heat input, efficiency, heat output, air output, and sound levels. The heaters operate on 230V and have specific gas consumption rates for natural gas and propane.
