OSO Hotwater Optima 225L Heat Pump Cylinder with 65L Buffer

The Optima 225L is a premium quality heat pump cylinder with a dedicated buffer tank in a single footprint halving the space required and a massive reduction in pipework. Reduced installation costs compared to a separate cylinder and buffer tank installation. Reduced labour, cheaper than buying two tanks and less materials required.

Time Saving - reduced installation time due to a much simpler installation. Plus, all pipework brought to a single area with no additional pipework to link two tanks.

Increased efficiency - Pre-heating the hot water cylinder through the buffer adds further load to the heat pump to keep COP high. Reduced pipework means less heat loss - pipework between buffer and cylinder if properly lagged (which it may not be) would not retain heat as well as the Optima - OGC which encapsulates both tanks within its foam lagging case

Increased comfort - A pre-heated hot water cylinder means the heat pump doesn’t have to switch into dedicated hot water mode for such a long time when hot water is called for via demand or timer. Because the dedicated hot water mode time is shorter, the property is deprived of space heating for a shorter time and the hot water achieves its desired temperature quicker

ADDITIONAL RENEWABLE INPUT, solar PV can be added to the on-board immersion heater. The Immersion heater position means you can heat 100% of the hot water tank if necessary. (from solar or mains)
