Is Pyrivo a good portable heater?

If you want to heat one small-to-medium room quickly without a trailing cable, Pyrivo is a strong fit. Because it plugs into the wall, it's easy to move from the office in the day to the bedroom at night. For a large lounge, consider two units – our multi-pack bundles bring the price per heater down.

As a rough guide, allow about 60–70W per m² in a reasonably insulated room. An 800W heater suits roughly 10–12 m².

Use a heater with a timer and overheat protection, and set it to switch off. Never leave it near bedding or covered.
