Fireplace Insert Prity M – 13.5 kW

The Same Straightforward Design. A More Compact Footprint.

The Prity M is the smaller sibling of the Prity G, carrying the same steel-fronted, ceramic glass construction into a more compact body suited to smaller rooms or tighter installation spaces. With 13.5 kW of radiant heat and class A energy efficiency, it delivers dependable heating performance without the larger footprint of its bigger sibling.

Made in Bulgaria. EU Ecodesign compliant.

How Much Space Can It Heat?

Prity doesn't publish an official heated-area figure for the Prity M, so this is our own estimate, based on the heated-area-to-power ratio observed across comparable Prity models in our range (roughly 7.5 m² per kW). At 13.5 kW, that puts the Prity M at approximately 100 m², depending on insulation, ceiling height, and room layout.

A Compact Body for Smaller Spaces

At 700 × 470 mm, the Prity M has a noticeably narrower profile than the standard Prity G, making it a practical choice for smaller rooms, tighter chimney breasts, or installations where a full-size insert simply won't fit. The firebox still measures a respectable 473 × 349 × 370 mm, keeping decent log capacity within the smaller frame. The ceramic glass door is kept clear by the secondary air wash system, which runs a continuous curtain of fresh air across the inner glass surface during burning.

Clean Combustion, Class A Efficiency

The Prity M achieves a combustion efficiency (η) of 77.7% and a seasonal space heating energy efficiency of 69%, with an energy efficiency index of 104 — placing it in energy class A. Emissions at nominal output are controlled across the board: CO at 1229 mg/Nm³, particulate matter at just 24 mg/Nm³, NOx at 90 mg/Nm³, and OGC at 12 mg/Nm³ — all within EU Ecodesign limits.

Fuel consumption at nominal output is 4.2 kg of dry wood per hour, with a flue gas temperature of 290°C and a mass flow rate of 9.5 g/s.

Important Installation Note

The Prity M uses a Ø150 mm flue outlet — narrower than most of our other inserts — and requires a minimum chimney draught of 12.8 Pa. Please confirm your chimney connection is compatible with this diameter before ordering. At 87 kg, it's also one of the lighter inserts in our range, which can simplify installation in tighter spaces.

Overall dimensions: 700 × 470 × 760 mm (W × D × H).
