Zonzini Stairclimber Delivery Surcharge – Sunamp Thermino 300 (ePlus 300 / xPlus 300) Scheduled Delivery
Zonzini Stairclimber Delivery Surcharge – Sunamp Thermino 300 (ePlus 300 / xPlus 300) Scheduled Delivery
This surcharge covers tracked stairclimber delivery by Zonzini for the Sunamp Thermino 300 heat battery — available as the Thermino ePlus 300 (direct electric) or the Thermino xPlus 300 (boiler / heat pump indirect). At 220–233 kg and 1,050 mm tall, the Thermino 300 is too large and heavy for a standard courier drop. Zonzini's specialist stairclimber equipment handles the unit safely wherever it needs to go — including up stairs and into awkward install locations. Please call us before ordering so we can book a suitable delivery slot.
Delivery of the Thermino 300 must be pre-arranged by phone. We need to confirm site access, agree a delivery window, and ensure the stairclimber team is briefed on your installation point. Call us on 01234 567890 before adding this surcharge to your basket.
- Tracked stairclimber delivery by Zonzini's specialist two-person crew — not a standard courier pallet drop.
- Delivery up stairs and into restricted install locations such as airing cupboards, plant rooms, and upper-floor utility spaces.
- Pre-booked time slot confirmed with you before despatch — no all-day waiting.
- Upright handling throughout — the Thermino 300 must never be laid on its side; Zonzini's equipment keeps it correctly oriented at all times.
- Proof of delivery documentation provided at handover.
The Thermino 300 contains Plentigrade P58 phase-change material and vacuum insulation panels. Tipping or laying the unit on its side can cause permanent damage and void the warranty. Zonzini's stairclimber equipment is specifically designed to keep heavy appliances upright throughout the delivery.
The Thermino 300 is Sunamp's largest fifth-generation heat battery — equivalent to a 300-litre hot water cylinder, but up to 4× more compact. It is available in two variants:
- Thermino ePlus 300 — charged by the mains grid via a built-in 2,800 W element; solar PV diversion upgradeable with the Optimino ePV key. Delivers 436 litres of hot water at 40 °C per charge.
- Thermino xPlus 300 — charged by a gas boiler or heat pump as primary source, with a built-in electric backup element. Configurable with Optimino keys for heat pump or PV integration. Delivers 333 litres at 40 °C per charge.
Both variants share the same footprint (365 mm W × 575 mm D × 1,050 mm H), use Plentigrade P58 phase-change material, carry a 10-year warranty on the heating element and PCM core, and require no mandatory annual maintenance. A thermostatic mixing valve (TMV) is required by UK Building Regulations at the hot water outlet.
