Back Boiler Fireplace Prity M W22, 22 kW

Back Boiler Fireplace Prity M W22, 22 kW – powerful radiator heating in a compact body

The Prity M W22 Wood Burning Fireplace in an elegant black graphite finish is a front-facing model designed for larger homes that want powerful central heating where installation space is limited. The 22 kW back boiler supplies the radiators in your home, while around 5 kW more heat radiates directly into the room where the fireplace is installed. This allows it to heat a volume of up to around 500–600 m³. Despite its high output, the body is only 700 mm wide and 520 mm deep, and the 36 L back boiler ensures steady heat transfer. With energy class A, 78.3% efficiency and a 3-year warranty, the M W22 is Prity's most affordable Back Boiler Fireplace over 20 kW. Made in Bulgaria by Prity 95 Ltd – a manufacturer of heating appliances since 1995.

Important for Installation and Operation

• 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 1.5 bar safety valve 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 connection to the system is via a G 1" inlet and outlet.
• The fireplace is heavy (146 kg) – check the load-bearing capacity of the floor.
