The Newark Copper Cylinder Co Ltd has manufactured solar cylinders for approximately 25 years. Over this time we have developed a wide range of solar cylinders, with different combinations of features including:
• Vented/ Unvented Single Coil Solar Cylinders
• Vented/ Unvented Twin Coil Solar Cylinders
• Vented/ Unvented Triple Coil Solar Cylinders
• Solar Thermalstores
• Vertical Solar Cylinders
• Horizontal Solar Cylinders
Our twin coil and triple coil solar cylinders are specifically designed to work in conjunction with the domestic heating system. The additional coils are designed to transfer heat from a more traditional heating source, for example, a domestic boiler and/or solid fuel boiler. The solar coil, which is manufactured from high efficiency finned tube with a large surface area, transfers heat from the solar panels into the solar hot water cylinder.
The boiler coil which (if fitted) is manufactured to BS 1566, can also be supplied as high recovery to reduce boiler cycling. Cylinder connection sizes can be specified as 22mm or 28mm compression. Our high efficiency 1.6m2 solar coil is fitted with 15mm or 22mm compression and with all connections protruding beyond the insulation, this makes our twin or triple coil solar cylinder one of the most efficient manufactured in the UK.
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 75mm 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 metallic finish.
Solar Cylinders are available as Vented Cylinders, Unvented Cylinders, or Thermalstores. 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). We can offer design drawings prior to manufacture to ensure that all connection sizes, positions and functions are to the customer's requirements.
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.
Uninsulated Diameter Calculator
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.)
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.
