Joule Twin Coil Copper Cylinder Hot Press Cylinder Immersion Tank 210L 60x18 1500x450mm Solar Compatible

Selling a Joule twin coil (dual coil / double coil) insulated copper hot water cylinder

— also commonly referred to as a hot press cylinder, hot press tank, immersion cylinder, immersion tank, boiler cylinder, indirect cylinder, vented cylinder, hot water storage cylinder, and storage cylinder.

Removed from a fully operational gas central heating system. Second hand / nearly new / used — in very good condition throughout.

This is a large-capacity, premium Grade 3 copper, pre-lagged / lagged cylinder unit that is solar panel compatible and a potentially suitable twin coil configuration for heat pump integration — a genuinely future-proof purchase at a very significant saving over new.

Comparable new cylinders of this type and specification retail for over €1,200. This represents an exceptional saving.

Why a Twin Coil / Dual Coil / Double Coil Cylinder?

A twin coil (dual coil / double coil) Grade 3 copper vented cylinder — whether you call it a hot press cylinder, immersion heater cylinder, immersion tank, boiler cylinder, or hot water storage cylinder / storage cylinder — is considerably more versatile than a standard single-coil unit:

Coil 1 — connects directly to your existing gas boiler, oil boiler, solid fuel back boiler, or any conventional central heating system
Coil 2 — allows integration of a solar thermal panel / solar panel cylinder system — no modification required; this unit is fully solar compatible / solar cylinder ready
With a substantial coil surface area of 3.28 m², heat transfer is rapid and highly efficient
Solar thermal cylinder / solar panel cylinder / solar cylinder — connect solar thermal panels directly to the second coil, using the sun as your primary heat source and the boiler as backup
Heat Pump Potential — ASHP / GSHP:

This cylinder has a coil surface area of 3.28 m², which falls within the 2.8–3.4 m² range commonly used in dedicated heat pump cylinders / heat pump compatible cylinders / heatpump cylinders. This means it may be suitable for integration with an ASHP (air source heat pump) or GSHP (ground source heat pump) system as a renewable energy cylinder.

However, prospective buyers should note that heat pump suitability — including whether this unit meets the specific low-temperature operating requirements of their chosen heat pump system — must be confirmed with their heating engineer or heat pump installer prior to purchase. This cylinder is not specifically certified or marketed as a dedicated heat pump cylinder. The seller makes no warranty as to its suitability for any particular heat pump system or configuration.

Suitable For:

Gas boiler systems, oil boiler systems, solid fuel back boiler systems, solar thermal systems, and potentially air source heat pump (ASHP) and ground source heat pump (GSHP) configurations — subject to installer verification. Compatible with all standard open-vented central heating systems. Ideal for a family home of 3–5+ people requiring high-volume hot water storage.
