Aerotermia · DHW with Haier & Mitsubishi Electric
Hot water with Haier & Mitsubishi Electric heat pump
Replace your gas boiler or electric water heater with a Haier Super Aqua or Mitsubishi Ecodan heat pump — 4× more efficient, smart app control, and runs on your solar panels.

What it is
An aerotermia hot-water unit (also called an HPWH) sits where your old electric tank or gas boiler did and serves the showers and taps. It runs on electricity but uses outdoor heat as its main fuel — typically 4× more efficient than a resistive heater.
Who it's for
Owners on bottled gas, an old electric tank, or a noisy boiler who want a quieter, cheaper, drop-in replacement without rewiring the whole house.

1. The outdoor unit captures thermal energy from the air — even on cold days (the Mitsubishi Ecodan Zubadan works down to -30 °C). 2. The compressor concentrates the heat via a refrigerant circuit (R290 in Haier, R32 in Mitsubishi). 3. The heat exchanger transfers the energy to the water tank (200–300 L for Haier Super Aqua). 4. Hot water is stored and available on demand for showers, taps and kitchen use.
Our brands

Haier
Haier Super Aqua: heat pump water heater with integrated 200–300 L tank, R290 refrigerant, COP up to 5.50, A+++ class. Operates down to -28 °C, heats water up to 80 °C. Smart scheduling via the hOn app.

Mitsubishi Electric
Mitsubishi Electric Ecodan: modular hydrobox for DHW. Zubadan compressor operates down to -30 °C, COP up to 5.05, 70 °C hot water output without backup heater. MELCloud app control.
What you get
About 4× the efficiency of an electric heater
For each kWh of electricity you put in, the heat pump moves roughly four kWh of heat into the tank — most of the energy is taken from the outside air, not your bill.
Integrates with the existing heating loop
Connects to your current pipework and tank fittings; you don't need to rebuild the system to gain the savings.
Drop-in replacement
Sits in the same footprint as a typical electric water heater or boiler, with standard plumbing and electric connections.
Smart app control
Schedule hot water heating from the Haier hOn or Mitsubishi MELCloud app. Combine with off-peak electricity tariffs to heat during the cheapest hours.
