SolarTank - 1

SolarTank Heating water storage tank, 300-3000 litres SolarTank is our range of vessels that store primary energy from different heat sources including boilers, solar heaters, heat recovery systems and others. This leaflet describes the standard cylinders that are available in capacities between 300 and 3000 litres and rated for 10 bar operation pressure. Pressure vessel code SolarTank meets the requirements of the PED 97/23/EEC code. Freshwater heating on demand SolarTank is designed for use in combination with instanta­ neous tap water heaters. The SolarTank can store energy from any heat source to generate hot tap water on demand in facilities where water flow is not constant – where sudden high demands occur on a fairly regular basis such as in blocks of flats, sports centres, schools, hotels and hospitals. When discharging the SolarTank in combination with an instanta­ neous tap water heater, the primary power demand can be substantially reduced since the SolarTank acts as a buffer on the primary side to meet the power peaks that occur at high tap water flow rates. Following such high tap water consumption, heating takes place very quickly and only on demand. This ensures a hygienic hot tap water supply that reduces the risk of lime scaling in the tap water system and scalding at the tap. Flexible energy sources The SolarTank can be connected to any type of primary heat source as long as it is connected in a closed heating loop. To heat tap water to the right comfort level when showering and bathing, we recommend a minimum charging temperature of 45 to 50°C for the primary heating water. High effectiveness for maximum hot water The effectiveness of this type of energy storage tank from which hot tap water is generated depends on its abil­ ity to keep the hot heating water separated from the cold return water that is admitted into the tank. The SolarTank is ­ articularly positive in this respect due to its internal tube p arrangement. The returned cold heating water is distributed gently across the bottom of the tank, which prevents it from mixing with the hot water that is fed on top of the vessel. The hot heating water is then drawn from the very top at the centre of the cylinder and is supplied to the instantaneous tap water heater. Moreover, since vertical storage tanks are more effective than horizontal ones, the SolarTank has an upright design. Effective and environmentally friendly insulation The insulation is made of 100mm rockwool cladded with an alaminium metal plate (Euroclass A) or 100mm glasswool with a PVC jacket (Euroclass B). The insulation is very easy to remove and refit, which makes the unit easy to transport in and out of the premises.
