<strong>Moorea</strong> I Condensing Water Heaters<br />
Features<br />
• Very high efficiency up to 108 %<br />
• Wide modulation range<br />
• No capacity constraints<br />
• Low pollution discharges<br />
• Small footprint & weight limits<br />
• Install up to 16 water heaters in cascade<br />
• Very quiet operation<br />
Advantages<br />
• Outputs available from 125 to 610 kW<br />
• Maximum energy utilisation<br />
• Efficiency of up to 108% net (97.5% gross)<br />
• High modulation range from 16% to 100% of<br />
nominal output (6.25 to 1)<br />
• Heat exchanger profile designed to ensure highly<br />
efficient heat transfer<br />
• Compact dimensions and small footprint<br />
• Lightweight aluminium/silicon heat exchanger<br />
• Top mounted hydraulic and flue connections<br />
revised<br />
• Easier to connect and less space needed for<br />
working access<br />
• NOx 35mg/kWh<br />
Application Examples<br />
Cascade without<br />
booster pump<br />
Not to be used if there are<br />
any high temperature circuits<br />
60/80 °C (no instant DHW) the<br />
motorised 2-channel valves<br />
isolate the water heaters when<br />
they are not operating. On<br />
start up the water heaters are<br />
blocked until their respective<br />
isolating valves are fully open. The<br />
Cascade function is integrated<br />
and a BUS module just needs to<br />
be added to each water heater<br />
regulator.<br />

Hot Water<br />
Tank<br />
Optimising the condensing<br />
"Cold" returns are used more,<br />
Thanks to the buffer tank, short<br />
cycles at high temperature are<br />
made smoother: loop losses, low<br />
drawing. The time for the water<br />
heater to reach its temperature<br />
is covered by the buffer tank; the<br />
tank's contents must be at least<br />
2.5 l /kW of installed power at<br />
high temperature.<br />
