Key Features

Benefits

• Supports reduced standing heat loss through 1.2 kWh/24h standby losses
• Factory-fitted components can reduce site assembly work
• Compact insulated dimensions assist installation where space is limited
• Smooth bore coil technology may help limit scale build-up

Technical Summary

200 litre standard uniSTOR heat pump cylinder with 198.4 l total tank capacity and 190.7 l actual capacity. Hot water draw-off is 172.5 l. Key figures include 1.2 kWh/24h standby losses, ErP class B, 26.0 kW coil rating, 14.6 minute reheat time at 70%, 85 °C maximum DHW temperature, 95 °C maximum heat circuit temperature, 50 mm insulation, 595 mm diameter, 1265 mm height, 46.0 kg empty weight and 237.4 kg filled weight.

Installation Notes

The cylinder includes an 18 l expansion vessel, sensor, factory-fitted immersion, tundish, three-way motorised valve and unvented cylinder kit. Standard connections are ¾ in BSP female for primary heat exchanger flow and return, and for cold and hot water connections. The 250 and 300 litre standard uniSTOR models include a secondary return T piece connection; this does not apply to the 200 litre model.

Efficiency

The standard uniSTOR range is described as having heat loss from as low as 1 kWh/24 hours. For the 200 litre model, standby losses are 1.2 kWh/24h. The cylinder also uses thermal injected polyurethane insulation with vacuum panels. Global Warming Potential is stated as less than five, with ozone depletion of zero.
