Premium Quality Copper Hot Water Cylinders Cylinders

Indirect hot water cylinders designed to work in conjunction with a pumped boiler and central heating system. Heat is transferred from the boiler to the water contained in the cylinder via a heat exchanger (also referred to as a boiler coil or heating coil).

Direct hot water cylinders were originally designed to be used in conjunction with solid fuel appliances and copper back boilers. Water from the cylinder would pass through the back boiler where it would be heated then returned to the cylinder. A modern direct hot water cylinder heats its contents with electric immersion heaters, often benefitting from lower rate Economy 7 electricity tariffs.

A combination hot water cylinder combines the functions of a gravity hot water store and cold water header tank.

Combining these functions makes them ideally suited to multi-storey developments, where space is limited or where the installation of the header tank is proving difficult. Combination cylinders are available as direct, indirect and Economy 7 models.

Economy 7 (Maxistore) hot water cylinders and combination tanks are designed to take advantage of the cheap rate night-time tariffs offered by electricity companies. When demand is lowest electricity is cheapest. So by heating water during the night significant savings in cost can be enjoyed. Provision is made for a daytime 'boost' element just in case demand for hot water is particularly heavy on occasions.

Horizontal hot water cylinders can be the solution when headroom is a problem. Particularly useful in confined loft spaces, a horizontal water cylinder can be configured as direct, indirect or Economy 7 and supplied with supporting cradles.

Marine Calorifiers

Hot water cylinders for boats can be manufactured in either vertical or horizontal format and factory insulated. Marine cylinders (also known as Calorifiers) can be supplied with single or twin coils where dual heat sources such as engine and solid fuel or gas boiler are available. The option of configuring connections exactly as you need them (for example: all on one side or in one end) makes our marine calorifiers ideal for retro fit when replacing old or to meet the challenges of new build for the designer.

A new range of Solar Thermal Store cylinders aimed at those who wish to combine solid fuel heat storage with solar energy. Available both in cylinder and combination style, the Solar Thermal Store unit provides hot water via a thermal mixing valve at high pressure supplied direct from the mains water supply. Simple to install with no requirement for an unvented certificate and being able to take various heating inputs the Solar Thermal Store offers far greater flexibility than the vented or unvented units.

Cylinders connected to uncontrollable heat sources such a solid fuel boilers, wood burning stoves, AGA's and such like can experience very high temperatures in the Feed & Expansion tank. Unless designed to cope, many plastic tanks are unsuitable for use under such conditions as high temperatures will cause the tank to distort and/or wilt which can lead to scalding hot water flooding from the vessel. Needless to say this can be lethal.

Most people own a heat pump and don't even realise it - your refrigerator is in fact a type of heat pump. Heat is extracted from the inside of the fridge to keep food fresh and is expelled through the radiator grill at the back of the unit. But when used in the opposite way, heat pumps extract heat from an outside source, and rather than the heat becoming a waste product, it is conveyed to a point of use within the premises. In this case, the point of use would be a hot water storage cylinder.

Twin coil and triple coil solar cylinders are specifically designed to work in conjunction with the domestic heating system. Solar cylinders are manufactured with either twin or triple independent coils. One or two coils are designed to transfer heat from an independent heating source, (eg. transferring heat from a central heating boiler or solid fuel boiler to the water in the solar cylinder) and the solar coil, which is manufactured from high efficiency finned tube with a large surface area, to transfer heat from the solar panels into the solar hot water cylinder.

Mains pressure hot water. A requirement for higher pressure, superior flow rates? Enjoy a "power" shower? Need to feed several outlets, wash basins or showers for instance, and still maintain pressure? Simple to install with no requirement for a cold water feed tank and supplied direct from the mains water, the unvented unit offers far greater flexibility than the traditional vented unit.
