Hitachi, Toshiba, De Dietrich & NIBE : air-to-water alternatives and NIBE geothermal

Beyond the big brands, other manufacturers are worth a look: Hitachi, Toshiba and De Dietrich in air-to-water, and NIBE, a geothermal specialist. Depending on your project, one of these options may be the most relevant. wendows installs this equipment, fine-tunes it and remains your point of contact for the warranty and after-sales service.

Technical strengths

What sets these secondary brands apart

Beyond the brand, it's the efficiency and the technology (air-to-water or geothermal) that guide the choice. The key figures for these ranges, sized and tuned by our teams.

Type Air-to-water & geothermal

Hitachi, Toshiba and De Dietrich cover air-to-water; NIBE brings geothermal, which draws warmth from the ground. We choose based on your home, your land and your budget.

SCOP up to ~5SCOP

The seasonal coefficient of performance (SCOP) reflects the real efficiency over a season. NIBE geothermal reaches high values thanks to the stability of the ground. The figure depends on the model and the sizing.

Warranty up to 5years

Manufacturer's warranty on the equipment, depending on the brand, the model and the maintenance plan taken out. wendows handles the follow-up and intervention when needed.

Sound level from ~36dB(A)

Recent air-to-water units stay discreet; geothermal, whose exchanger is in the ground, is by nature very quiet on the outside. Placement at installation counts.

Flow temperature up to ~65°C

The high-temperature versions let you keep existing radiators in a renovation. Geothermal maintains excellent efficiency even when demand rises.

Control Via app

Each brand offers its own control app to schedule, track consumption and adjust remotely. Comfort becomes clear and easy to adjust through the seasons.

Why consider Hitachi, Toshiba, De Dietrich or NIBE?

When you replace your heating, you choose two things: a heat pump brand and an installer. Alongside the leaders, these four brands broaden the field of possibilities — notably towards geothermal with NIBE, a technology often overlooked but very high-performing.

Hitachi (Yutaki) and Toshiba (Estia) extend Japanese know-how into air-to-water, with a reputation for reliability. De Dietrich brings the sturdiness of a long-standing manufacturer and a solid parts network. NIBE, for its part, is the geothermal specialist: the heat pump draws warmth from the ground, for very stable efficiency year-round.

"Geothermal asks more of the installation, but it gives it all back over the years: the ground doesn't freeze, and neither does its efficiency.

That's where our role as installer counts. We calculate heat loss and, for geothermal, study the land and the collectors. We size the right output, set the heating curves and remain your single point of contact for the warranty, maintenance and after-sales service.

5

A SCOP only geothermal reaches. By drawing on the stable warmth of the ground, a NIBE geothermal heat pump maintains high efficiency all year round, independent of the outside air.

On budget, these brands cover a wide range. Air-to-water sits in the usual brackets; geothermal calls for a higher upfront investment, offset by durably high efficiency. To place your project, start with our prices & grants page, then ask for a costed quote.

FAQ Hitachi, Toshiba, De Dietrich & NIBE

Your questions about these heat pump brands

Why consider a secondary heat pump brand?

Because the best choice isn't always a leader. Hitachi, Toshiba and De Dietrich offer reliable air-to-water units, and NIBE opens the door to geothermal, which is very high-performing. Depending on your home, your land and your budget, one of these options may be the most relevant.

What does NIBE geothermal bring?

The geothermal heat pump draws warmth from the ground rather than from the air. Since the ground temperature is stable year-round, so is the efficiency: it doesn't collapse in deep cold. In return, the installation (collectors or drilling) calls for a higher upfront investment.

Are these brands as good as the market leaders?

Yes, they are established manufacturers with a parts and after-sales network. Hitachi and Toshiba rely on Japanese know-how, De Dietrich on a long heating heritage, NIBE on Scandinavian geothermal expertise. The result depends mainly on the sizing and the installation.

Is geothermal possible at my place?

It depends on your land: available area for horizontal collectors, or the possibility of vertical drilling. We assess the feasibility during the ground study. Where it's possible, the durably high efficiency often makes it an excellent choice over the long term.

What warranty applies to these heat pumps?

Depending on the brand, the model and the maintenance plan taken out, the manufacturer's warranty can be extended. wendows handles the follow-up and intervention. The exact terms, and the recommended annual maintenance, appear on your quote.

How much does one of these heat pumps cost installed?

Budget from around €10,000 for a Hitachi, Toshiba or De Dietrich air-to-water heat pump installed, and from ~€18,000 for a NIBE geothermal heat pump (collectors and drilling included). Heat pump grants and 6% VAT deducted afterwards.
