background: #FFFFFF;\"\u003eChoose the variant that matches your \u003cstrong\u003ecalculated heat loss\u003c\/strong\u003e at your local winter design temperature. As a rough guide: 9 kW for 3–4 bed homes; 12 kW for larger 4–5 bed homes; 16 kW for very large or light-commercial properties, or where a 3-phase supply exists. Because T-CAP holds full capacity to -20°C, you don't need to oversize for cold-weather margin.\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails style=\"border: 1px solid #E5E7EB; border-radius: 4px; margin: 8px 0; overflow: hidden;\"\u003e\n\u003csummary style=\"cursor: pointer; background: #008377CF; color: #fff; padding: 10px 14px; font-weight: 600; list-style: none;\"\u003eWhat's the difference between this and the T-CAP Mono J Generation (R32)?\u003c\/summary\u003e\n\u003cdiv style=\"padding: 12px 16px; background: #FFFFFF;\"\u003eBoth use T-CAP technology, but this \u003cstrong\u003eM Series\u003c\/strong\u003e range uses \u003cstrong\u003eR290\u003c\/strong\u003e (GWP 3, full output to -20°C, up to 75°C flow) versus the \u003cstrong\u003eJ Generation's R32\u003c\/strong\u003e (full output to -15°C, up to 60°C flow).
