Back Boiler Fireplace Prity P W18, 18.4 kW

Back Boiler Fireplace Prity P W18, 18.4 kW – Whole-Home Radiator Heating and a Wide Fire

The Prity P W18 Back Boiler Fireplace in an elegant black graphite finish combines the cosiness of a built-in fireplace with the efficiency of central heating. The 18.4 kW back boiler supplies the radiators in the home, while a further approx. 5 kW of heat is radiated directly into the room where the fireplace is installed. This allows it to heat a volume of up to approx. 430–510 m³. The wide combustion chamber (827 mm) creates a long, panoramic flame and takes logs up to 63 cm long, while the shallow body (410 mm) makes building in easier. 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. Made in Bulgaria by Prity 95 Ltd – a manufacturer of heating appliances since 1995.

Important Notes on Installation and Use

• Do not light the fireplace without water in the back boiler and without connected radiators or convectors – this will damage the appliance.
• An open heating system is recommended. With a closed system, a safety valve rated at 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 recommended to power the circulation pump via a UPS so that it keeps running during a power cut.
• If the system contains copper components, protect it against electrolysis with a magnesium anode or similar protection. Protect all parts from freezing.
• The fireplace requires a chimney with a diameter of 200 mm. Connection to the system is via a G 1" inlet and outlet.
