Prity CF E Fireplace Insert with Air Jacket – 16.5 kW

Radiant Heat in the Room. Warm Air Wherever You Route It.

The Prity CF E pairs a powerful 16.5 kW firebox with a built-in air jacket — a convection chamber that draws in cool air, warms it as it circulates around the firebox, and releases it through dual Ø128 mm ducts. That means you can route warm air not just into the room where the insert sits, but into an adjoining space entirely, extending its reach well beyond a standard insert.

With a firebox that runs on just 1.2 kg of wood per hour at nominal output — remarkably low for this power class — and an 82.6% efficiency rating, very little of what you burn goes to waste. Energy Class A+, with an EEI of 109.

How Much Space Can It Heat?

The CF E is suitable for heating spaces of up to 125 m², depending on insulation, ceiling height, and room layout — and further still if the air jacket ducting is routed to heat an additional room beyond the one it's installed in.

The Air Jacket: One Fire, Two Rooms

Most fireplace inserts heat only the room they're installed in. The CF E's air jacket changes that. Cool air is drawn into the chamber surrounding the firebox, heats as it passes across the hot metal casing, and exits through two Ø128 mm ducts — one of which can be routed through a wall or ceiling void to deliver warm air directly into a second room, while the other continues to vent into the room where the insert sits.

This is passive convection, driven by the natural rise of heated air — no fan or electricity required. It works quietly alongside the insert's direct radiant heat, which continues to warm the room through the ceramic glass door regardless of how the ducted air is routed.

A Large Firebox, Efficiently Burned

The firebox measures 536 × 496 × 326 mm — spacious enough for substantial log loads — yet the CF E consumes only 1.2 kg of wood per hour at nominal output, a notably efficient burn rate for a unit producing 16.5 kW. The flue gas temperature of just 213°C confirms that heat is being extracted from the fire rather than lost up the chimney.

Emissions at nominal power are CO 955.0 mg/Nm³, dust 22.0 mg/Nm³, NOx 81.0 mg/Nm³, and OGC 102.0 mg/Nm³, all measured at 13% O2 — within EU Ecodesign limits. The seasonal space heating energy efficiency (ηs) of 71.5% reflects real performance across a full heating season, not just laboratory conditions.

Installation Requirements

The CF E uses a Ø200 mm flue outlet and requires a minimum chimney draught of 13 Pa. As with all fireplace inserts, installing a flexible stainless steel liner inside your existing chimney is necessary to ensure safe and efficient operation — your existing chimney flue alone is rarely sufficient. A qualified installer will assess your chimney and confirm the correct liner diameter before installation.

At 180 kg, this is a substantial unit. Professional installation is strongly recommended, and you should confirm your fireplace opening can accommodate the CF E's dimensions before ordering.

30 Years of European Engineering Behind Every Weld

Prity has been manufacturing solid fuel heating appliances in Gorna Oryahovitsa, Bulgaria since 1995. With over 250 production workers and a product range refined over three decades, they build inserts that earn their place in a home for many years. Every unit is manufactured to EN 13229, the European standard for fireplace inserts, including open fires burning solid fuels.

Your CF E comes with a 24-month manufacturer's warranty.

What's in the Box

Insert body with integrated air jacket and dual air ducts, door with ceramic glass, ash drawer, handle set with air regulator, technical manual. A flexible stainless steel chimney liner is not included and should be sourced separately based on your installer's assessment.

Use only dry, chemically untreated natural wood or wood briquettes without adhesives. Wood moisture content must not exceed 20%. Do not burn household waste, painted wood, plywood, or impregnated timber. Installation must be carried out by a qualified professional, including assessment of your chimney and installation of an appropriate flue liner. Always consult a qualified installer before connecting to your chimney system. Note: this model weighs 180 kg — professional installation is required.
