Determining the type of installation1. Type of installation / no. of persons2. Heat source(s)3. Access possibilities / headroom
How to dimension: • Write a requirements specification for the
system by defining type of system (residential, industrial, school etc.) and the number of people the system will serve.
• Clarify if any alternative energy sources are available, and which sort of energy output these can offer.
• Check access for transporting the water heaters into the building, and headroom in the area where the system will be fitted. When combinations of energy sources are available specific calculations must be done. No. of users is a determining factor. With access to these data the dimensioning tables on the next page can be used to determine the correct volume and effect for your system. Available access and space determines the water heater diameter and height.
OSO 600 l. will go through a 0.8 m. door. The largest stainless steel volume to fit through a 1 m. door is 1000 l. Both are well suited for serial connection of several units up to 10.000 l. Optionally use fewer water heaters from 1.500 - 10.000 l., but note that these has a larger diameter and height and will as such demand more access and installation space/height.
Water quality is importantLimescale-rich water is a problem for electric elements. In systems with high levels of limescale a system for descaling should be fitted.
Heat sourcesOSO Unique electric central has optional effect and voltage. The temperature is adjustable from 60-90°C, and the effect is optional from 2,5-15 kW in steps of 2,5 kW. A large accumulation volume is best for operational economy.
External energy sources are suitable for the M-series, in combination with the OSO Turbo system or with Maxi Coil heaters. With increasing energy accessability the tank volume can be reduced, depending on the usage pattern. In high water usage systems a large tank volume is still necessary. Tje OSO Turbo system is highly efficient for systems demanding 100 kW effect or more, and is the most space efficient.
A heat pump demands a large water volume to achieve even, economical running. Booster heaters are required to increase water temperature to avoid bacterial growth in the system.
Energy savingUsage: With a moderate water pressure and limited hot water usage up to 50% can be saved on both water and energy. Water heaters: Fewer, larger water heaters has approx. 50% lower heat loss than a large number of 300-400 litre units.

should not be aggressive, i.e. the water chemistry shall comply with the following:
• Chloride < 250 mg / L • Electric Conductivity (EC) @25°C < 750 µS / cm • Saturation Index (LSI) @80°C > - 1,0 / < 0,8 • pH level > 6,0 / < 9,5
• The immersion heater has not been exposed to hardness levels exceeding 5°dH (180 ppm CaCO3). A water softener is recommended in such cases.
• Any disinfection has been carried out without affecting the Product in any way whatsoever. The Product shall be isolated from any system chlorination.
• The Product has been in regular use from the date of installation. If the Product is not intended to be used for 60 days or more, it must be drained.
• Service and/or repair shall be done according to the installation manual and all relevant codes of practice. Any replacement parts used shall be original OSO spare parts.
• The Service record / Benchmark logbook has been completed and updated after each annual service. Invoices should be kept as proof of service.
