Here, that ratio applies to the unit's \u003cstrong\u003ecombined output of 26.1 kW\u003c\/strong\u003e — 5 kW radiating into the room plus 21.1 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 ATC W20 at approximately \u003cstrong\u003e195 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\u003eCast Iron Door and Window Frames: Heat Retention All Around\u003c\/h2\u003e\n\u003cp\u003eCast iron absorbs heat progressively during combustion and releases it back slowly — long after sheet steel would have cooled. On the Prity ATC W20, that material isn't limited to the main door: the two angled side windows are cast iron-framed as well, giving the whole front of the insert the same slow, steady heat retention rather than just the central panel. Ceramic glass throughout keeps the fire visible from the front and both angles, kept clear by the secondary air wash system that runs fresh air across the inner glass surfaces during burning.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003eCorner Placement, Three-Sided Visibility\u003c\/h2\u003e\n\u003cp\u003eLike the rest of the Prity A range, the ATC W20 is shaped to fill a room corner, radiating heat across a wide arc of the room rather than throwing it in a single direction from a flat wall. The two angled side windows add to that — the fire stays visible from more of the room than a single front-facing pane allows.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003eA Water Heat Exchanger Built for Central Heating\u003c\/h2\u003e\n\u003cp\u003eThe Prity ATC W20 delivers \u003cstrong\u003e21.1 kW to its water heat exchanger\u003c\/strong\u003e at nominal output, alongside 5 kW of direct radiant heat into the room. The water tank holds \u003cstrong\u003e34 litres\u003c\/strong\u003e, with a maximum working pressure of \u003cstrong\u003e1.25 bar\u003c\/strong\u003e and \u003cstrong\u003e1″ water connections\u003c\/strong\u003e for both flow and return.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThis is a boiler-type appliance: it must be connected to a working central heating system before use, and should never be run dry or disconnected from your water circuit.\u003c\/strong\u003e Installation and commissioning by a qualified heating engineer is required.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003eClean Combustion, Class A Efficiency\u003c\/h2\u003e\n\u003cp\u003eThe Prity ATC W20 achieves a \u003cstrong\u003ecombustion efficiency (η) of 80%\u003c\/strong\u003e and a \u003cstrong\u003eseasonal space heating energy efficiency of 71%\u003c\/strong\u003e, with an energy efficiency index of 106 — placing it in \u003cstrong\u003eenergy class A\u003c\/strong\u003e.
