PRITY P W18 Wood-Burning Fireplace Insert with Water Boiler

PRITY P W18 is a fireplace insert with a water jacket, combining an integrated fireplace setting with heat for a connected water-based heating system. The surround and heating circuit should be planned together to make the most of the appliance.

Useful warmth, matched to your home

The rated output to the room is 5.1 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 listed water-side output is 18.4 kW. Consider this separately from the heat released into the room, and have the heating circuit, controls and required safety equipment sized for the appliance.

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 78.3 %. 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

This is an insert rather than a finished freestanding fireplace. The enclosure needs suitable non-combustible materials, ventilation and access for servicing in accordance with the manufacturer’s instructions. The finished surround is not included in the appliance dimensions.

The appliance body measures 890 × 410 × 790 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 Ø200 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 144 kg. Check access through doors and any steps on the delivery route, and make sure the supporting floor and hearth are suitable.

A water-jacket model requires a correctly designed, filled and protected heating circuit. It must not be treated as an ordinary room stove or operated with the water jacket empty. Follow the manufacturer’s installation scheme.

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.
