At Mibec we supply a wide range of different tank products for hot water applications; in this short article we take a look at Calorifiers – specifically what are they, their sizing and uses. Calorifiers are basically water storage tanks fitted with a suitable heating coil in their lower half. This can then be connected to an external heat source, such a gas boiler or a renewable energy system, for example a heat pump or a boiler for wood or pellets. Calorifiers are suitable for hot water storage in a number of applications, from a small domestic dwellings (serving a similar purpose to an immersion heater in a house), to supplying hot water in commercial buildings e.g. for shower rooms in hotels, schools, sports facilities or public buildings.
The basic function of a calorifier is to retain thermal energy for later use and can supplement the heat source when demand is high or store heat when demand is less. Stored heat can be immediately accessed without the heat source needing to get up to temperature; this can be very useful for an immediate response, maintaining a constant output over the day and improving energy efficiency and the longevity of the system.
We offer a wide range of tanks for use in various heating applications from leading European manufacturers such as Cordivari with many products held in stock in the UK, for immediate despatch. Our calorifiers meet regulations such as the PED (Pressure Equipment Directive) and 2009/125/CE (ErP – Eco-friendly planning regulations). Calorifiers from Cordivari have special Polywarm® protective linings which are specially designed using a glass enamel coating material for potable water applications and have WRAS approval – which certifies the product for use in drinking water installations and is a prerequisite in most commercial projects. The heat exchanger coils used in Cordivari products also have Antilegionella® technology, again addressing a critical design consideration for commercial clients and of huge benefit for facilities manager’s ongoing maintenance programs.
We can supply calorifiers in a wide range of sizes to suit any application, from small domestic tanks right up to industrial or commercial projects, which often require tanks anywhere from 500 litres to 10,000 litres. Tanks can be designed to be orientated in vertically or horizontally to suit the ceiling void or roof space available and at Mibec we can work with the architect or heating services engineer to develop the specification for the size and orientation of the tank required for the project.
We offer a full free of charge design and specification service covering the whole of the UK, designed to support architects, specifiers or contractors. We can give you knowledgeable, yet impartial advice on selecting the right calorifier tank to meet your heating needs.
