De’Longhi Nano Radiator TRNS0505M: what works, what doesn't?

What works well

  • Established brand: De’Longhi stands for reliable heaters with decent support
  • Continuously variable thermostat: fine temperature control instead of coarse steps for constant comfort
  • Frost protection function: automatically keeps the room above freezing, handy for cellars or holiday homes
  • Economical 500 W: low power consumption, ideal for spot warmth in small rooms
  • Easy to transport: carry handles on both sides make moving between rooms easier

Points of criticism

  • Low output: 500 W is only enough for small rooms up to 15 m³, not a heater for large rooms
  • High price per watt: from €78 clearly more expensive than more powerful no-name radiators

Build quality & everyday use

What carries the De’Longhi Nano Radiator TRNS0505M in everyday use: established brand (De’Longhi stands for reliable heaters with decent support) and continuously variable thermostat (fine temperature control instead of coarse steps for constant comfort). We have to be honest about the weaknesses: low output, as 500 W is only enough for small rooms up to 15 m³, not a heater for large rooms.

If you set the device up to save space, make sure it stands on a stable, level surface with some air around it. This protects the mechanics and electronics in continuous use.

“De’Longhi Nano Radiator TRNS0505M: established brand and continuously variable thermostat, and the trade-off is low output. At 8.3/10 a fair deal from €78.”

Frequently asked questions about the De’Longhi Nano Radiator TRNS0505M

What room size is the TRNS0505M meant for?
De’Longhi states up to 15 m³, which corresponds to a small room of around 6 m² at normal ceiling height. For larger rooms the 500 W is too little.
What does the frost protection function do?
It automatically keeps the room temperature at a minimum level so that frost does not form. That is useful for rarely used rooms such as cellars or guest rooms.
Is the premium over no-name devices worth it?
The TRNS0505M costs more than comparably powerful budget radiators. You pay for the brand, the continuously variable thermostat and the support you can expect; if you only look for maximum watts, you will find cheaper alternatives.
