Test your flow rate with a 1-litre measuring jug and stopwatch. \u003cstrong\u003eThe TSMEB-9 (9.6 kW) is the most popular model\u003c\/strong\u003e and is the right choice for most UK homes where the outlet flow rate reaches 4–5.5 l\/min. If your flow rate is lower (e.g. a restricted hand basin), a TSMEB-6 or TSMEB-7 may be sufficient. If you need higher flow rates than any single unit can provide, two units installed in tandem give up to 11 l\/min. The variant table on this page lists the maximum flow rate at a +25°C temperature rise for each model.\u003c\/div\u003e\n\u003c\/details\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"border: 1px solid #cde3e1; border-radius: 8px; margin-bottom: 10px; overflow: hidden;\"\u003e\n\u003cdetails\u003e\n\u003csummary style=\"padding: 14px 18px; font-size: 15px; font-weight: bold; color: #005c54; cursor: pointer; list-style: none; display: flex; align-items: center; justify-content: space-between; background: #f5fbfa;\"\u003e\u003cspan\u003eWhat electrical supply does the MEB need?\u003c\/span\u003e\u003csvg stroke-width=\"2.5\" stroke=\"#008377\" fill=\"none\" viewbox=\"0 0 24 24\" height=\"18\" width=\"18\"\u003e\u003cpolyline points=\"6 9 12 15 18 9\"\u003e\u003c\/polyline\u003e\u003c\/svg\u003e\u003c\/summary\u003e\n\u003cdiv style=\"padding: 14px 18px 16px; font-size: 15px; color: #444; line-height: 1.65; border-top: 1px solid #cde3e1; background: #fff;\"\u003eEach model requires a \u003cstrong\u003ededicated single-phase 240V circuit\u003c\/strong\u003e with an RCBO for circuit protection.

Set your heat pump or solar thermal system to run at its optimum flow temperature for efficiency. The MEB is installed downstream and \u003cstrong\u003etops up to the desired outlet temperature\u003c\/strong\u003e using only the precise amount of electrical energy needed. Because the MEB is nearly 100% efficient and only operates when there is a shortfall, running costs in this configuration are typically very low.\u003c\/div\u003e\n\u003c\/details\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"border: 1px solid #cde3e1; border-radius: 8px; margin-bottom: 10px; overflow: hidden;\"\u003e\n\u003cdetails\u003e\n\u003csummary style=\"padding: 14px 18px; font-size: 15px; font-weight: bold; color: #005c54; cursor: pointer; list-style: none; display: flex; align-items: center; justify-content: space-between; background: #f5fbfa;\"\u003e\u003cspan\u003eIs there any risk of scaling or limescale build-up?\u003c\/span\u003e\u003csvg stroke-width=\"2.5\" stroke=\"#008377\" fill=\"none\" viewbox=\"0 0 24 24\" height=\"18\" width=\"18\"\u003e\u003cpolyline points=\"6 9 12 15 18 9\"\u003e\u003c\/polyline\u003e\u003c\/svg\u003e\u003c\/summary\u003e\n\u003cdiv style=\"padding: 14px 18px 16px; font-size: 15px; color: #444; line-height: 1.65; border-top: 1px solid #cde3e1; background: #fff;\"\u003eNo. Because the MEB uses \u003cstrong\u003edirect energy transfer rather than a heating element\u003c\/strong\u003e, there is no hot surface for limescale to deposit on. Conventional instantaneous heaters and immersion elements develop a calcified coating over time that reduces efficiency and eventually causes burnout — the MEB is immune to this failure mode.
