Prity K1 Optima 9.5 kW Wood Burning Stove

Prity K1 Optima brings wood-fired warmth into the room where you spend time. It is a room-heating stove: the useful heat is released around the appliance, making the fire part of everyday life as well as the room’s atmosphere.

Useful warmth, matched to your home

The rated output to the room is 9.5 kW. This is the figure to compare with the room’s calculated heat demand: a well-matched stove should provide comfortable warmth without needing to be continually throttled back.

The space a stove can heat depends on insulation, ceiling height, windows and how rooms connect. A higher kW rating is not automatically a better choice. Matching the output to your home helps you choose a stove that suits the way you live.

What the efficiency means in practice

The listed efficiency is 77.8 %. Under the declared test conditions, this is the share of the fuel’s energy converted into useful heat. It helps compare appliances, but is not a promise of a fixed saving on your heating bill.

The energy efficiency class is A. Read it alongside the output and efficiency figures: the energy label supports comparison, while the right size for your home remains just as important.

For good results, use the wood specified in the operating instructions, keep it properly seasoned and follow the recommended fuel load and air settings. Wet wood and unsuitable operation can reduce performance and make the glass and flue dirtier.

Design that fits the way you use the room

A freestanding stove gives you a defined focal point without requiring a full built-in fireplace surround. Consider the view from your seating area, access to the loading door and the route of the flue when choosing its position.

The appliance body measures 390 × 390 × 760 mm (width × depth × height). These dimensions help you compare its presence in the room and plan the delivery route. The final installation also needs space for the hearth, flue and required safety clearances.

Plan the installation before you order

The listed flue connection diameter is Ø130 mm. This is a starting point for checking chimney compatibility; the required draught, connection arrangement and local installation rules also matter.

The listed appliance weight is 57 kg. Check access through doors and any steps on the delivery route, and make sure the supporting floor and hearth are suitable.

Have a qualified installer check the chimney, combustion-air supply, floor protection and the manufacturer’s clearances. Appliance dimensions alone do not establish a safe installation position. Keep the operating instructions for future use and maintenance.
