An electric heating package with an integrated 180-litre hot-water cylinder.
CH means central heating; DHW means domestic hot water. Nominal model labels are shown separately from verified ratings. Gas CH maximum/minimum values use the non-condensing basis; a second maximum is shown only where a verified condensing rating is available. The source basis below controls the comparison. No missing value is calculated from another variant.
| Model / fuel | Nominal label (kW) | CH maximum (kW) | DHW output (kW) | CH minimum (kW) | DHW at ΔT 35°C |
|---|---|---|---|---|---|
| Electromax 6 Radiator · Electricity | 6 | 6 | Stored water / separate design | Not verified | Not a verified instantaneous flow rating |
| Electromax 9 Radiator · Electricity | 9 | 9 | Stored water / separate design | Not verified | Not a verified instantaneous flow rating |
| Electromax 9 Underfloor · Electricity | 9 | 9 | Stored water / separate design | Not verified | Not a verified instantaneous flow rating |
| Electromax 6 Underfloor · Electricity | 6 | 6 | Stored water / separate design | Not verified | Not a verified instantaneous flow rating |
The product page repeats Amptec S dimensions and conflates the immersion rating with the heating boiler. These dimensions are omitted. Heating ratings follow the Electromax installation manual; the 3 kW immersion rating is separate.
The current page’s headline 10-year warranty is not used as whole-appliance cover. The installation manual specifies 10 years for the stainless steel cylinder, 2 years for the electric boiler and other valves/fittings/electrical parts, and 5 years for the DHW expansion vessel. Confirm current component terms before ordering.
The floor-standing package includes a circulating pump and stored hot water. It needs assessed electrical supply, cylinder safety arrangements, discharge routing and access.
Radiator and underfloor variants are separate configurations. The electric boiler’s cover is distinct from the stainless steel cylinder guarantee.
Electrical supply capacity, phase, protective devices, wiring, heating distribution and hot-water storage need a qualified assessment. High point-of-use efficiency does not establish low running costs; tariffs and the home’s heat loss matter. No gas or LPG conversion is implied.
Component-specific cover in the official manual: 10 years stainless steel cylinder; 2 years electric boiler and other valves, fittings and electrical parts; 5 years DHW expansion vessel. Current terms, installation and maintenance conditions must be confirmed in writing.
Manufacturer warranty, SwiftHeat installation cover and qualifying Care+ services are separate. Keep the required registration, commissioning and service records. Your quotation confirms the exact terms before purchase.
Manufacturer warranty information · Ongoing servicingExact controller, wiring and generation must be checked against the manufacturer instructions; no universal smart-control compatibility is assumed.
Only the verified fuel configurations are shown. LPG is not inferred from the Baxi brand name.
Discuss heating controlsAssess electrical capacity, hydraulic design, hot-water storage and safety requirements before comparing electric heating packages. A flue-free appliance still needs safe positioning and servicing access.
A same-arrangement replacement, relocation and conversion involve different work. SwiftHeat confirms the appliance and complete installation scope after survey. Assess First. Recommend Second.
The guide separates nominal model labels from verified heating output. Electrical supply voltage and phase also matter. A heat-loss calculation and installation assessment are still required.

No. It combines an electric boiler with a 180-litre stored-hot-water cylinder. Cylinder delivery and reheating are assessed separately from the boiler’s electrical rating.
Checked 1 October 2026. Availability and terms can change; the exact appliance and current instructions are confirmed again at quotation.
Official Baxi product photography and trademarks remain the property of their respective owners. Manufacturer warranty graphics do not confirm the eligibility of a SwiftHeat package.
The installed price for your selected boiler is confirmed after assessment. The quotation covers the appliance, controls, flue, system preparation and any required pipework. A conversion or relocation can have a different scope from a straightforward replacement.
New boiler installations from £1,790 inc. VAT apply to a qualifying standard, straightforward replacement: one bathroom, fewer than 10 radiators and a standard horizontal flue, subject to survey. Specification and warranty selection affect the final cost. This is a general starting offer and is not a price for every model in this catalogue.
Read the starting-package conditions0% options over 3, 6, 9 or 12 months through Humm Group Limited, subject to application, affordability, eligibility, approval and provider terms. Any applicable deposit, fees and repayment conditions are confirmed during your enquiry/application. Acceptance is not guaranteed.
Finance terms and chargesTwo free annual services and a Hive Mini are available on qualifying installations only. Every model is considered under the qualification rules; inclusion in this catalogue does not confirm eligibility. Ask us to confirm the offer in your quotation.
Ask about Care+ eligibilityPlan the maintenance your appliance requires and keep its service records. If you are considering replacement because of a fault, diagnosis can help establish whether repair is a suitable option first.
Boiler servicing · Repair advicePrice confirmed following assessment for this configuration. The general New boiler installations from £1,790 inc. VAT offer does not apply to every model or property.
From or indicative prices remain provisional. SwiftHeat issues a written fixed quotation for the agreed scope after the appropriate property and installation assessment, technical checks and warranty-package verification. Remote information gathering may be suitable initially; a home survey is required where the necessary checks cannot be completed remotely.
We assess heat loss, heating and hot-water requirements, water supply, controls and installation access before recommending an appliance. Bedroom count or a catalogue model number alone cannot establish the right boiler.
