16px;background:#f9fefe;\"\u003eThe SX stores water at a high temperature (up to 70°C) and the built-in \u003cstrong\u003eblending valve mixes it with cold water\u003c\/strong\u003e to deliver at approximately 40°C — the typical shower temperature. Because the stored water is hotter than the delivered temperature, mixing produces more total volume. OSO's design specifically maximises this ratio, giving around \u003cstrong\u003e20% more usable water than competitors' cylinders of the same nominal size\u003c\/strong\u003e.\u003c\/div\u003e\n  \u003c\/details\u003e\n\n  \u003cdetails style=\"border:1px solid #c8e6e3;border-radius:6px;margin-bottom:10px;overflow:hidden;\"\u003e\n    \u003csummary style=\"background:#008377CF;color:#fff;padding:13px 16px;cursor:pointer;font-weight:600;list-style:none;\"\u003eIs the SX150 compatible with a heat pump?\u003c\/summary\u003e\n    \u003cdiv style=\"padding:14px 16px;background:#f9fefe;\"\u003eThe SX150 is a \u003cstrong\u003edirect electric cylinder\u003c\/strong\u003e and is not designed as a primary heat pump cylinder. For heat pump installations, OSO recommends the \u003cstrong\u003eDelta GeoCoil DGC\u003c\/strong\u003e range, which features a large tube heat exchanger optimised for low-temperature heat pump operation. The SX immersion can serve as electric backup in a hybrid system, but it should not be the primary heat source.\u003c\/div\u003e\n  \u003c\/details\u003e\n\n  \u003cdetails style=\"border:1px solid #c8e6e3;border-radius:6px;margin-bottom:10px;overflow:hidden;\"\u003e\n    \u003csummary style=\"background:#008377CF;color:#fff;padding:13px 16px;cursor:pointer;font-weight:600;list-style:none;\"\u003eCan I use the SX150 with an Economy 7 or off-peak electricity tariff?\u003c\/summary\u003e\n    \u003cdiv style=\"padding:14px 16px;background:#f9fefe;\"\u003eYes — the twin immersion heater configuration is ideal for \u003cstrong\u003edual tariff (Economy 7\/10) operation\u003c\/strong\u003e. The lower immersion heats the full tank overnight on cheaper off-peak electricity, while the upper element provides a top-up boost during peak hours when needed. This is a cost-effective way to reduce electricity bills for all-electric properties.\u003c\/div\u003e\n  \u003c\/details\u003e\n\n  \u003cdetails style=\"border:1px solid #c8e6e3;border-radius:6px;margin-bottom:10px;overflow:hidden;\"\u003e\n    \u003csummary style=\"background:#008377CF;color:#fff;padding:13px 16px;cursor:pointer;font-weight:600;list-style:none;\"\u003eCan I connect a solar PV diverter to the SX150?\u003c\/summary\u003e\n    \u003cdiv style=\"padding:14px 16px;background:#f9fefe;\"\u003eYes. Either immersion heater can be connected to a \u003cstrong\u003esolar PV diverter\u003c\/strong\u003e (e.g. myenergi Eddi, Solic 200, iBoost) — diverting surplus generation into free hot water. The upper immersion is typically used for solar diversion as it heats the top of the tank most quickly, providing usable hot water with minimal delay.\u003c\/div\u003e\n  \u003c\/details\u003e\n\n  \u003cdetails style=\"border:1px solid #c8e6e3;border-radius:6px;margin-bottom:10px;overflow:hidden;\"\u003e\n    \u003csummary style=\"background:#008377CF;color:#fff;padding:13px 16px;cursor:pointer;font-weight:600;list-style:none;\"\u003eDoes the SX150 need to be near a drain for the discharge pipe?\u003c\/summary\u003e\n    \u003cdiv style=\"padding:14px 16px;background:#f9fefe;\"\u003eYes. As an \u003cstrong\u003eunvented cylinder\u003c\/strong\u003e, the SX150 requires a T\u0026amp;P relief valve discharge pipe (tundish) that discharges safely to an appropriate drain or external location in accordance with G3 Building Regulations. The tundish is included in the integrated G3 kit under the top lid. The discharge must be visible and routed correctly — your G3 engineer will arrange this during installation.\u003c\/div\u003e\n  \u003c\/details\u003e\n\n\u003c\/div\u003e","brand":"OSO Hotwater","offers":[{"title":"Default Title","offer_id":63264205013341,"sku":"11011686","price":990.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0958\/2051\/3629\/files\/OsoSagaXpress150LUnventedDirectHotWaterCylinderPre-Plumbed.jpg?v=1770020582","url":"https:\/\/qualityheating.co.uk\/products\/oso-150l-unvented-direct-hot-water-cylinder-pre-plumbed","provider":"AIZO Quality Heating","version":"1.0","type":"link"}
