HPCyl- Twin Coil Boiler & Heat Pump (Insulated)
HPCyl- Single Coil HP Specification
• For use in Domestic Properties
• For use with solid fuel appliances
The heat energy produced by a heat pump can be transferred into a hot water cylinder via a high efficiency finned, copper coil - the same way a common gas or oil boiler would heat your hot water. However, the coils in our Heat Pump cylinders have a far larger heating surface than traditional domestic boiler coils. This allows the coil to dissipate as much heat as the heat pump can possibly produce, preventing the heat pump from cycling.
Since the maximum temperature that most heat pumps can achieve, is 55°C it would usually be necessary to have at least one other form of heat input to the cylinder as a backup, for example, immersion heater, gas/ oil boiler, or any other heat application, which is capable of raising the temperature of the stored water to around 60 - 65°C. The heat pump application can also be combined with solar heating to achieve a very environmentally friendly and highly efficient method of heating your hot water.
Manufactured in accordance with the relevant British Standards and in compliance with Part L of the Building Regulations, these cylinders combine a high performance heating coils with low heat loss, factory applied insulation, to provide a highly efficient and effective way to store and provide domestic hot water. Our polyurethane foam lagging can, in most cases, be applied up to a thickness of 100mm and is the most environmentally friendly type available, with an ozone depletion potential of zero and a global warming potential of one. For a more aesthetically pleasing finish, we can offer a steel case with a silver metallic finish.
Heat Pump cylinders are available in both vented and unvented specifications. They can also be manufactured as Combination Units if the property has limited head room and the installation of a separate feed and expansion tank is going to prove difficult. Each unit can come complete with immersion heater(s) and a drain valve. Other options are also available to meet customers' particular needs, including Economy 7 specification and additional connections (e.g. for shower supply).
Matching customers' requirements is particularly important when space is at a premium, so the most common customisation for a hot water cylinder, is the “mixing and matching” of the various heights and diameters that we offer. As additional parts of a Bespoke design, the customer is able to specify a number of options including coil sizes (where applicable), connection sizes/positions, insulation thickness, whether it is manufactured from copper or stainless steel (see our Copper vs. Stainless Steel page for a comparison), and the finish of the unit (the silver metal case being the premium option). It is also possible to combine different types of cylinders to result in the optimum solution for your individual situation. We can offer design drawings prior to manufacture to ensure that all connection sizes, positions and functions are to the customer's requirements.
See our Bespoke Products page if you require a unit which may be slightly out of the ordinary and please contact us if you require any advice.

To assist with determining the correct size connection for replacement units or units to fit your current system, we have created a table of external and internal thread sizes.
Uninsulated Diameter Calculator
This calculator is designed to assist the specification of a cylinder by determining the amount of hot water available from a cylinder of a specific size; this can be particularly useful in situations where space for a cylinder is limited.
This calculator is designed to assist the specification of a cylinder by determining the size of the cylinder from it's circumference and insulation thickness; this can be particularly useful in situations where a replacement cylinder is required, but due to the insulation it is difficult to determine the size of cylinder required.
Please note - The final figures are approximate and should be rounded to the nearest standard diameter (375,400,450 etc.)
