Here, that ratio applies to the unit's \u003cstrong\u003ecombined output of 23.5 kW\u003c\/strong\u003e — 5.1 kW radiating into the room plus 18.4 kW into the water circuit, which spreads its heat through radiators installed around the house rather than from the insert itself. Combined, that puts the Prity M W18 at approximately \u003cstrong\u003e175 m²\u003c\/strong\u003e, depending on your home's insulation, radiator layout, and how the heating system is balanced.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003eA Compact Body That Still Packs a Boiler\u003c\/h2\u003e\n\u003cp\u003eDespite its more compact 700 × 590 mm footprint, the Prity M W18 fits in a full water heat exchanger without sacrificing firebox capacity — the combustion chamber still measures a generous \u003cstrong\u003e575 × 490 × 360 mm\u003c\/strong\u003e.
