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.

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.
