Telford Tempest Pre Plumbed 300L Cylinder 50L Buffer For Samsung Heat Pump

The Telford 300L/50L Pre‑Plumbed Cylinder for Samsung (product code TSMI300/50/HP/PP/SAM) is a 300L Tempest unvented stainless‑steel heat pump cylinder with an integrated 50L buffer vessel, pre‑plumbed and pre‑wired for quick installation with Samsung air source heat pumps, including a dedicated Samsung control package.

Key Features

• Pre‑plumbed Tempest cylinder – factory‑assembled pipework and wiring significantly reduce installation time and site labour compared with loose‑component builds.
• Integrated 50L buffer – built‑in 50L buffer store optimises system volume and flow, improving heat pump cycling, defrost performance and system stability.
• Heat pump optimised coil – large surface‑area coil specifically designed for low‑temperature heat pumps to maximise heat transfer into the stored water.
• Duplex stainless‑steel construction – high‑grade stainless steel cylinder body for excellent corrosion resistance and long service life.
• Lifetime inner vessel warranty – lifetime manufacturing warranty on the inner container with 2‑year warranty on components, subject to Telford terms and registration.
• Samsung‑specific configuration – supplied pre‑plumbed and pre‑wired around Samsung controls and hydraulics, simplifying compliant Samsung system builds.

Pre‑Installed Components

• Samsung control box and wired controller (MIM‑E03EN) – dedicated Samsung mono controller and room interface, pre‑mounted and pre‑wired for direct integration with Samsung heat pumps.
• Pre‑wired 3‑port diverter valve – Midsummer 3‑port diverter valve fitted and wired for automatic DHW / heating changeover control.
• Secondary circulation pump – Grundfos pump (approx. 7.5 m head) fitted on the secondary circuit to ensure adequate cylinder and system circulation.
• Integrated 50L buffer vessel – factory‑built buffer section within the cylinder assembly to provide additional system volume and hydraulic decoupling.
• Filling loop and pressure gauge – pre‑installed filling loop and pressure gauge simplify system filling, pressurisation and routine checks.
• Safety and inlet components – 15–22mm tundish, T&P relief valve, 22mm inlet group valve and automatic air vent are factory‑fitted for safety and compliance.
• Immersion heaters – 3kW immersion heaters in both the main tank and buffer provide backup heat and legionella protection options.

Other Included Accessories

• Samsung flow sensor – supplied flow sensor for correct monitoring and control by the Samsung heat pump system.
• Potable expansion vessel – separate expansion vessel provided to manage potable hot‑water expansion, typically supplied with bracket for wall mounting.

Cylinder Specifications

• Nominal cylinder capacity: 300L domestic hot‑water storage.
• Integrated buffer volume: 50L.
• Empty weight: approximately 122kg.
• Full weight: approximately 417kg.
• Height: around 2040mm.
• Diameter: approximately 580mm.
• Primary coil size: about 3m² heat‑pump coil surface area.

Product Details & Performance

• Product code: TSMI300/50/HP/PP/SAM (Tempest Heat Pump with 50L Buffer Samsung Pre‑Plumbed).
• Standing heat loss: approximately 2.28kWh/24h (around 95W) under standard test conditions.
• Maximum primary pressure: 3 bar on the primary (heat pump) side.
• T&P relief valve setting: typically 7 bar, with factory‑fitted 7 bar / 90°C T&P valve.
• Immersion heater rating: 3kW in the main tank and 3kW in the buffer section.

Compatibility & Applications

• Compatible heat pumps: specifically configured for Samsung Gen6, Gen7 and HTQ air source heat pumps; not suitable for Samsung integrated heat pumps which incorporate their own cylinder package.
• System type: indirect unvented mains‑pressure hot‑water cylinder for use with Samsung ASHP as primary heat source, with integrated buffer for space‑heating hydraulic stability.
• Installation use case: ideal for new‑builds and retrofits where a fast, tidy, Samsung‑approved pre‑plumbed cylinder solution is required to minimise site wiring and first‑fix complexity.

Warranty & Registration

• Warranty cover: lifetime manufacturing warranty on the inner stainless‑steel container and 2‑year warranty on factory‑fitted components, subject to Telford’s terms and correct installation.
• Registration: the cylinder must be registered with Telford after installation, via the Telford product registration portal, to activate the full warranty.
