Product Overview

Comfort moves into your home with the WPE-I H Premium inverter geothermal heat pumps. This device uses the heat from the ground for heating and hot water operation. The year-round constant heat output with high flow temperatures offers maximum living comfort regardless of the season.

Product Details

Output-controlled inverter geothermal heat pump for indoor installation with a high degree of integration. Ideally suited for use in new buildings and renovations due to very high flow temperatures. Depending on the heating load of the building, it can also be used for apartment buildings.

The constant source temperature ensures a year-round continuous heat output with high flow temperatures of up to 75 degrees Celsius. The integrated heat pump controller enables fully automatic control of the heating system. A highly efficient circulation pump and a pressure expansion vessel are included for the brine and heating side. An electric emergency / additional heater, a switch valve and a safety valve with a blow-out hose are integrated as standard. The refrigeration circuit works with the environmentally friendly and future-proof refrigerant R454C.

The built-in inverter ensures optimal heat pump operation all year round and thus maximum efficiency.

Internal pressure hoses enable a direct hydraulic connection to the heating and brine circuits. For easy installation, the hydraulic connections are equipped with quick connectors and are already thermally insulated. Transport is made easier by carrying handles on the rear wall.

Is the WPE-I 06-15 H Premium capable of active cooling?

No, the WPE-I 06-15 H Premium is specifically designed as a heating-only heat pump. It does not have the capability to provide active cooling.

Can I cascade multiple WPE-I 06-15 H Premium units?

No, the WPE-I 06-15 H Premium cannot be cascaded with other units. It is a standalone heating-only heat pump.

Can I use a 'forced cascade' configuration with two WPE-I 06-15 H Premium heat pumps?

Yes, in a 'forced cascade' configuration, you can use two WPE-I 06-15 H Premium heat pumps to heat and prepare hot water. However, there are specific requirements for this setup.

What are the requirements for a 'forced cascade' configuration?

In a 'forced cascade,' the heat pumps must not share a common ground loop. Instead, each heat pump should have its own separate loop.

What is the maximum brine temperature allowed for the WPE-I 06-15 H Premium?

The maximum brine temperature entering the WPE-I 06-15 H Premium should not exceed 20°C. Exceeding this temperature can lead to high-pressure errors and compressor shut-offs. Over time, this can affect the lifespan of the compressor.
