HDC1500i as a Solar Booster

The HDC1500i will deliver 16 l/min @ 50˚C Rise using 5.4m³ gas. If we increase the incoming water temperature we get the following saving:

Flow rateEnergySaving on gas
16l/min @ 40°C Rise 44.7kW 21% (1.2m3)
16l/min @ 30°C Rise 33.5kW 21% (1.2m3)
16l/min @ 20°C Rise 22.3kW 40% (2.2m3)
16l/min @ 10°C Rise 11.0kW 61% (3.5m3)

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

*This is based on an installation in Southampton, south facing and an inclination of 45˚
