{"title":"Gas Combi Boilers","description":"\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eOur gas combi boiler range covers A-rated, 24–30kW instant hot water and heating units from Baxi, Vaillant, Ariston, Biasi, Glow-Worm and Viessmann, with warranties from 7 to 10 years depending on model. Combi boilers heat water on demand directly from the mains, combining central heating and hot water in a single wall-mounted unit with no cold water tank or hot water cylinder required — making them the standard specification for flats, new builds, and 1–4 bedroom properties with a single bathroom.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eSizing: kW rating vs actual hot water delivery\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eA combi's headline kW figure is its domestic hot water (DHW) output, not its central heating output — a \"30kW combi\" typically delivers only 18–24kW to the heating circuit, with the remainder going to instantaneous water heating. This is a common point of confusion: buyers often assume a higher kW figure guarantees stronger showers, but flow rate is what determines that. At a standard 35°C temperature rise, every roughly 2.5kW of DHW output delivers about 1 litre per minute, so a 24kW combi produces around 9.8 l\/min while a 30kW unit delivers closer to 12 l\/min. Boiler Plus sets a minimum flow rate standard of 10 l\/min for new combi installations, and flow can only be as good as the incoming mains supply allows — a strong boiler paired with a weak mains feed won't outperform the pipe.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eWhen a combi is — and isn't — the right choice\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eCombis suit intermittent, single-outlet demand: one shower or bath running at a time. Where two bathrooms may be used simultaneously, splitting the available flow rate reduces performance at each outlet, and a system boiler with an unvented cylinder is usually the better specification.

Boiler Plus also requires a system filter to be fitted on all new gas boiler installations to protect against magnetite sludge; see our magnetic filter and scale inhibitor ranges for compatible products. All gas combi boiler installation and commissioning must be carried out by a Gas Safe registered engineer.\u003c\/p\u003e","products":[{"product_id":"worcester-greenstar-4000-30kw-erp-combi-boiler","title":"Worcester Greenstar 4000 30kW (ERP) Combi Boiler","description":"\u003cp\u003eThe \u003cstrong\u003eWorcester Greenstar 4000 30kW (ERP) Combi Boiler\u003c\/strong\u003e is a compact, efficient condensing combination boiler designed to provide heating and hot water for apartments and properties with one bathroom.

Dina platform with several key upgrades: a \u003cstrong\u003e1:10 modulation ratio\u003c\/strong\u003e (vs 1:5 on the Dina), a \u003cstrong\u003e10-litre expansion vessel\u003c\/strong\u003e (vs 7 L),

When paired with an \u003cstrong\u003eexternal weather-compensation probe\u003c\/strong\u003e, the boiler continuously adjusts its flow temperature to match the actual heat demand, maximising efficiency and occupant comfort.\u003c\/div\u003e\n  \u003c\/details\u003e\n\n  \u003cdetails style=\"border:1px solid #dde8e7;border-radius:6px;margin-bottom:8px;\"\u003e\n    \u003csummary style=\"background:#008377CF;color:#fff;padding:11px 15px;border-radius:5px;cursor:pointer;font-weight:600;list-style:none;\"\u003eWhat fault codes does the Antares display and can I read them remotely?\u003c\/summary\u003e\n    \u003cdiv style=\"padding:13px 15px;font-size:15px;\"\u003eThe Antares stores the \u003cstrong\u003elast 10 fault codes\u003c\/strong\u003e in its on-board Fault History menu, each time-stamped and accessible via the control panel under the main menu.

of combustion gases, which increases resistance in the flue system. Ariston's published maximum vertical run for the E-Combi ONE on Ø60\/100 is \u003cstrong\u003e8 metres at 24 kW and 7 metres at 30 kW\u003c\/strong\u003e. Each 90° elbow (3318075) deducts from these totals — refer to the installation manual for the specific deduction per fitting. If the installation requires more than 7 metres, upgrading to the \u003cstrong\u003eØ80\/125 coaxial system supports up to 24 metres\u003c\/strong\u003e on the 30 kW model, though this requires a different starter and larger roof penetration.\u003c\/div\u003e\u003c\/details\u003e\u003cdetails style=\"border:1px solid #ddd;border-top:none;padding:0;\"\u003e\u003csummary style=\"padding:14px 16px;cursor:pointer;font-weight:600;background:#f9f9f9;\"\u003eShould I choose the 24 kW or 30 kW for my lodge or static caravan?\u003c\/summary\u003e\u003cdiv style=\"padding:14px 16px;border-top:1px solid #eee;\"\u003eThe key differentiator is \u003cstrong\u003ehot water demand\u003c\/strong\u003e. If your property has \u003cstrong\u003etwo bathrooms or two shower rooms\u003c\/strong\u003e, or if guests frequently use hot water simultaneously, the \u003cstrong\u003e30 kW (3301132)\u003c\/strong\u003e is the better choice — its 12.5 l\/min flow rate provides noticeably better shower performance under concurrent use than the 24 kW's 10.4 l\/min. For a \u003cstrong\u003esingle-bathroom caravan or smaller lodge with one wet room\u003c\/strong\u003e, the \u003cstrong\u003e24 kW (3301131)\u003c\/strong\u003e is adequate and may run more efficiently at part load since it modulates to a lower minimum output proportionally.\u003c\/div\u003e\u003c\/details\u003e\u003cdetails style=\"border:1px solid #ddd;border-top:none;padding:0;\"\u003e\u003csummary style=\"padding:14px 16px;cursor:pointer;font-weight:600;background:#f9f9f9;\"\u003eDoes the 3319235 fit the same Morco and Worcester Bosch roof flashings regardless of boiler output?\u003c\/summary\u003e\u003cdiv style=\"padding:14px 16px;border-top:1px solid #eee;\"\u003eYes.
