HD50i as a Solar Booster
HD50i as a solar booster The HD50i will deliver 12.6 l/min @ 50˚C Rise using 5.02m³ gas. If we increase the incoming water temperature we get the following saving:
|Flow rate||Energy||Saving on gas|
|12.6l/min @ 40°C Rise||35.1kW||21% (1.05m3)|
|12.6l/min @ 30°C Rise||26.4kW||40% (2.0m3)|
|12.6l/min @ 20°C Rise||17.6kW||61% (3.1m3)|
|12.6l/min @ 10°C Rise||8.8kW||81% (4.1m3)|
A 20 tube panel will yield approx 1439kW/yr* so a fairly standard arrangement of 3 panels would yield 4317kWh/yr
Consequently this equates to 4317kW free energy or the equivalent of 401.6 m³ gas per annum
