Back Boiler Fireplace Prity P W18 TV, 18.4 kW – Modern Design and Whole-Home Heating via Radiators

The Back Boiler Fireplace Prity P W18 TV, finished in elegant black graphite, combines modern design with central heating for your home. The 18.4 kW back boiler supplies the radiators, while around another 5 kW of heat is radiated directly into the room where the fireplace is installed. This allows it to heat an area of up to 105 m² – a suitable solution for medium-sized houses and apartments. The wide combustion chamber (450 x 657 x 385 mm) allows generous loading and long burning, while the thermal-shock-resistant ceramic glass provides a clear view of the flames. With energy class A, an efficiency of 78.3% and a 3-year warranty, the fireplace is a reliable solution for heating the whole home. It is made in Bulgaria by Prity 95 Ltd – a manufacturer of heating appliances since 1995.


Advantages of the Back Boiler Fireplace Prity P W18 TV

  • Modern design – a clean look that fits contemporary interiors.
  • 18.4 kW back boiler – heats the whole home via radiators.
  • Additional radiant output of approx. 5 kW – the room with the fireplace is heated directly.
  • Heated area up to 105 m² – suitable for medium-sized houses and apartments.
  • Wide combustion chamber – 450 x 657 x 385 mm, for generous loading and long burning.
  • Thermal-shock-resistant ceramic glass and cast iron grate – clear view of the flames and even burning.
  • Combustion control damper and manual flue damper – for control over the flame and the chimney draught.
  • Sturdy steel body – made of steel with a thickness of 2 mm, top plate of 3–4 mm, and a metal door handle.
  • 3-year warranty – a longer warranty than on fireplaces without a back boiler.

Efficiency and Energy Class

The Back Boiler Fireplace Prity P W18 TV complies with the European eco-design requirements known as Ecodesign, which ensures low harmful emissions, high efficiency and environmentally friendly combustion of the wood. With energy class A, an efficiency of 78.3%, compliance with the Ecodesign standard, CE certification and a 3-year warranty, it provides economical and environmentally friendly heating. The chimney diameter is 200 mm, with top outlet.


Important for Installation and Use

  • Do not light the fireplace without water in the back boiler or without connected radiators or convectors – this will damage the appliance.
  • An open-vented heating system is recommended. In a sealed system, a safety valve set to 1.5 bar is mandatory.
  • The fireplace has no built-in overheating protection – the system must be designed and installed by a specialist.
  • With forced circulation, it is advisable to power the circulation pump via a UPS, so that it keeps working during a power cut.
  • If the system contains copper components, protect it from electrolysis with a magnesium anode or similar protection. Protect all parts from freezing.
  • The fireplace requires a chimney with a diameter of 200 mm. The flue pipes must have the same diameter as the fireplace outlet. The connection to the system is via G 1" inlet and outlet.
  • The fireplace weighs 130 kg (without water) – check the load-bearing capacity of the floor.
