Comparison of heat pump types

Overview

Air

The most popular

The air/water heat pump is installed indoors or outdoors. No other heat pump can be installed so quickly and cost-effectively.

Earth probe

The longest-term

The geothermal heat pump is installed inside the house in a compact way. In the long term, no other heating system is as cost-effective.

Groundwater

The most powerful

The groundwater heat pump is also installed in the house. It is worthwhile for larger outputs where a lot of energy can be saved.

Modernisation

Groundwater Heat Pump in a Single-Family Home

There is a large groundwater reserve of extremely high quality in the Aare Valley, between Thun and Bern. Part of the Münsingen community is built on this groundwater area. One neighbourhood in this community features a single-family home that uses the energy from this groundwater for heating.

Refurbishment

Air source heat pump in converted building

The former Bleiken community centre today houses three rental apartments, a fire station and some school facilities. Its old oil-fired heating system has been replaced with a modern air/water heat pump supplied by CTA.

Modernisation

Mini-neighbourhood heating cooperative

In a terraced house in Basel, a nano-cooperative is providing heat. This neighbourhood cooperative provides 90% of heating from renewable energy, instead of the previous 33%. This is despite the fact that gas-fired heating systems are still fitted in two of the three residential units.

Neubau

Living in and with nature

Eleven buildings with a total of 110 flats. This is "Les Rives de Bramois" in Sion. Remarkably, the buildings only account for 20% of the site area. The remaining 80% are sustainable green spaces and places for non-motorised traffic.

Modernisation

Oil tanks are out; air source heat pumps are in

Owing to his job at Swisshaus, the owner had already established an interest in heating technology as part of the energy transition. Now, he’s also taken this home with him. The oil heating system gave way to an external air source heat pump from CTA.

New building

Air source heat pump for an apartment house

The new, quiet, high-performance heat pump from CTA is an ideal fit for the linear architectural style of this new apartment house with view over Lake Thun.

Renovation with ground-source heat pump

Renewable heating in a heritage-protected building

The Schenini family lives in a sustainably inhabited house. Sustainable, because this timber-framed building has allowed people to live here for generations. It is now also heated sustainably: the old oil-fired heating system has been replaced by a CTA ground-source heat pump.

Redevelopment

Harvesting air as a pair

In this farmhouse, the existing oil-fired heating system was replaced with two interconnected air/water source heat pumps using the natural refrigerant propane. The building owner is now happy to be able to heat the farmhouse using sustainable energy and an environmentally friendly refrigerant.

Redevelopment

12 opinions, one solution

Using a clever redevelopment strategy, the owner of the “Alte Schmitte” development in Lohn-Ammannsegg replaced the power-hungry electric heaters of the 1980s with efficient and economical geothermal heat pumps from CTA. Each flat now has a heat pump that is roughly the size of a wardrobe. For heating and hot water, these use heat from a geothermal probe field common to each building.

Redevelopment

Making new from old

In 2018, a 40-year-old family home was entirely renovated to Minergie-standard. The major components for the completely new building services include an air/water source heat pump, a roof-integrated photovoltaic system and comfort ventilation.
