Thermia Diplomat Optimum G2

Saves energy and money without compromising on hot water

Diplomat Optimum G2 produces greater amounts of hotter water than any other heat pump on the market while using less energy.
The previous model, Diplomat Optimum, ranked number one in the category of most water and hottest water in the test of heat pumps carried out by the Swedish Consumer Agency. We’ve now moved up yet another notch – the Diplomat Optimum G2 operates at a 10% higher annual efficiency than its predecessor, meaning you can reduce your heating costs by more than 75%.

Our new, patent-pending HGW technology utilizes existing home heating to produce hot water at the same time. That means you get hot water as a bonus when you heat your home with this heat pump.

The integrated TWS technology means that the hot water is produced faster and at higher temperatures than with traditional technology. As the hot water is diluted to tap water temperature, the volume of usable hot water is considerably higher due to the high temperature.

The pump utilises rock, surface ground, ground water and lake water as its heat sources. Read more about how a geothermal heat pump works.

Using the Thermia Online optional feature, you can control your heat pump via the Internet. In the unlikely event that something needs rectifying, you will be alerted automatically via SMS text message or e-mail.
