Initial situation

Consumption : 1 300L of domestic hot water per day
Negative cold : R449a system – Cooling capacity = 16 300W & Heat rejection = 28 800W (at -30/+45°C)

Proposal / study

1x 60kW heat recovery system for evaporator defrosting + 1 x 70kW system for domestic hot water production
1 x 1 000L for warm glycol storage + 1 x 1 500L for domestic hot water storage

Measurements taken

Average energy recovered per day : 500kWh/day
Annual energy savings : 129 967kWh/year

Total annual savings : approx. €6,291/year, i.e., equiv. to 15.95 tonnes of CO2/year

Actual return on investment : 3.4years
