RADIATORS
PURMO GROUP SALES DIRECTOR FOR IRELAND JOHN KELLY OUTLINES HEAT EMITTER OPTIONS TO HELP SPECIFIERS, INSTALLERS AND BUILDING MANAGERS MAKE INFORMED DECISIONS FOR RESIDENTIAL AND COMMERCIAL PROJECTS… Radiators for low temperature heating
Fan-assisted radiators, like the Ulow E2, are perfect for low-temperature systems and heat pumps.
Fan coil units such as the iVector S2 are ideal for year- round comfort.
Panel, fan-assisted and fan coil units each have unique performance characteristics.
PANEL RADIATORS Panel radiators remain popular due to their simplicity, wide range and
FAN RADIATORS Fan-assisted radiators, like the Ulow E2, have integrated fans to boost convection, delivering up to 60% more output than standard panels. This makes them perfect for low-temperature systems and heat pumps. BENEFITS: • Faster heat delivery: Fans (and optional boost mode) speed up warm air distribution. • Space saving: Smaller size for the same output. • Improved airflow: Air moves more effectively, eliminating cold spots. • Cooling option: Creates a pleasant cool summer breeze in warm weather. CONSIDERATIONS: • Noise: Fans do generate a level of noise, although low-level sound (up to 34dB). • Power required: Needs a nearby power connection (fused spur). Best for: Renovation projects, energy upgrades, and rooms needing quick heat delivery.
FAN COIL UNITS Fan coil units such as the iVector S2 handle both heating and active cooling by blowing air over coils carrying hot or chilled water. Highly responsive and compatible with heat pumps, they are ideal for year-round comfort. BENEFITS: • Heating & cooling: Dual functionality in a single unit. • High efficiency: Excellent output at low temperatures, even as low as 40/32/20°C. • Flexible installation: Floor, wall, ceiling or recessed options. • Precision: Integrated control unit, with remote control and BMS options. CONSIDERATIONS: • Installation complexity: Needs electrical connection and, for cooling, a condensate drain. • Noise: Up to 57dB in boost mode, comparable to moderate rainfall. • Higher upfront cost: But offset by long-term system efficiency.
affordability. Operating through a mix of convection (around 65%) and radiant heat (35%), they work well with high- and low- temperature systems from 90°C down to 45°C. BENEFITS: • Versatile designs: Available in standard or designer models, in various colours. • Silent operation: No moving parts = no noise. • Economical: Lower upfront and maintenance costs. • Flexible sizing: Ideal for retrofits and new builds alike. CONSIDERATIONS: • Slower heat-up time compared to fan-assisted options. • Wall space required: Larger models may be needed for low-temperature systems. Consider vertical options. Best for: Homes, schools, healthcare and offices. LST radiators are ideal for safety- critical environments.
Best for: Offices, hotels, retail, schools and homes which require heating and cooling.
CONCLUSION Choosing the right heat emitter depends on space, system temperature and performance needs. Understanding the strengths of options enables installers to design HVAC systems that are efficient and future ready. To see working models, visit the Uppercross Enterprises showroom in Dublin.
