Telford Tempest Pre Plumbed 250L Cylinder 50L Buffer For Samsung Heat Pump

The Telford 250L/50L Pre‑Plumbed Cylinder for Samsung (product code TSMI250/50/HP/PP/SAM) is a 250L Tempest unvented stainless‑steel heat pump cylinder with an integrated 50L buffer vessel, factory pre‑plumbed and pre‑wired to provide a fast, tidy installation with Samsung air source heat pumps.

Key Features

• Pre‑plumbed Tempest cylinder – duplex stainless‑steel unvented cylinder with pre‑fabricated 28mm pipework and wiring to minimise on‑site labour and first‑fix time.
• Integrated 50L buffer – built‑in 50L buffer store improves system volume, protects against short‑cycling and enhances heat pump defrost and flow stability.
• Heat pump optimised coil – large‑surface‑area coil specifically designed for low‑temperature heat pumps to maximise heat transfer and system efficiency.
• Mains‑pressure hot water – delivers high‑flow, mains‑pressure domestic hot water suitable for modern bathrooms and multiple outlets.
• Long‑life construction – Duplex stainless‑steel inner vessel with high‑performance insulation and robust fittings for durability and low standing heat losses.

Pre‑Installed Components

• Samsung control box and wired controller (MIM‑E03EN) – Samsung mono controller and user interface pre‑mounted and pre‑wired for seamless integration with compatible Samsung heat pumps.
• 3‑port diverter valve (pre‑wired) – factory‑wired diverter valve to manage DHW / heating priority without additional wiring centres.
• Secondary circulation pump – Grundfos pump (approx. 7.5m head) fitted on the secondary circuit to ensure correct flow through the cylinder and heating system.
• Integrated 50L buffer – internal buffer vessel within the cylinder assembly, eliminating the need for a separate external buffer tank.
• Filling loop and pressure gauge – pre‑installed filling kit and pressure gauge for easy filling, pressurisation and ongoing system checks.
• Safety and control components – 15–22mm tundish, temperature and pressure relief (T&P) valve, 22mm inlet group valve and automatic air vent, factory‑fitted for compliance and safety.
• Immersion heaters – 3kW immersion heater in the main tank and 3kW immersion heater in the buffer section for backup heating and pasteurisation cycles.

Other Included Accessories

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

Cylinder Specifications

• Nominal DHW capacity: 250L.
• Integrated buffer volume: 50L.
• Empty weight: approximately 110kg.
• Full weight: approximately 357kg.
• Height: around 1778mm.
• Diameter: approximately 580mm.
• Primary coil size: around 3m² heat‑pump coil surface area.

Product Details & Performance

• Product code: TSMI250/50/HP/PP/SAM (Tempest Heat Pump with 50L Buffer Samsung Pre‑Plumbed, 250L).
• Standing heat loss: approximately 2.11kWh/24h (about 88W) under standard test conditions.
• Maximum primary pressure: 3 bar on the primary (heat pump) circuit.
• T&P valve setting: typically 7 bar / 90°C via the factory‑fitted T&P relief valve.
• Immersion heater rating: 3kW in the main cylinder and 3kW in the buffer vessel.

Compatibility & Applications

• Compatible heat pumps: specifically configured for Samsung Gen6, Gen7 and HTQ air source heat pumps and not suitable for Samsung integrated heat pumps which already incorporate a cylinder package.
• System type: indirect, unvented mains‑pressure hot‑water cylinder with integrated buffer, designed for use with a Samsung ASHP as the primary heat source.
• Ideal use cases: small to medium dwellings where a 250L cylinder with an integrated 50L buffer provides an optimal balance of DHW storage, plant‑room footprint and system stability.

Warranty & Registration

• Warranty: lifetime manufacturing warranty on the inner stainless‑steel vessel and 2‑year warranty on factory‑fitted components (terms and conditions apply).
• Registration: the cylinder must be registered with Telford after installation via the Telford online registration portal to validate the extended warranty.
