* Heat exchanger output depends on temperatures and flow rates. The OVB rated output applies to a 60 °C difference between the inlet heating water and inlet pool water.
** Indicative recommendation by our shop. Before installation, assess heat-source output and temperature, flow in both circuits, desired heating speed and pool heat losses.
Boiler, heat pump or solar collector?
The exchanger transfers heat between two separate circuits rather than generating it. With a low-temperature source, do not assume catalogue output without checking actual conditions. A larger exchanger cannot increase the boiler or heat pump’s own output.
For salt water, select only an exchanger explicitly approved by its manufacturer for that use, such as a suitable titanium model.
