Vaillant: Heat pumps, heating controls and connected services

Vaillant makes heat pumps and heating systems, with myVAILLANT services and documented local EEBUS and cloud integration paths.

Summary

Best for
Building heating and hot-water projects that need matched heat-pump, indoor-unit and control components, with an established installer and service channel.
Less suited to
Projects requiring several energy-management systems to command the same heat pump: EnergiePLUS explicitly excludes simultaneous connection to another energy manager.
Deployment
On-site heating equipment and controls, with myVAILLANT connect and regional app or energy-management services.
Data in
Heating-system temperatures, operating states and energy information through the matched controls. Local EEBUS and cloud APIs are distinct integration routes.
Pricing
Heating equipment and installation are specified together; optional connected services have separate regional terms.

Overview

Vaillant's history begins with Johann Vaillant's workshop in Remscheid in 1874. The brand is part of a family-owned group whose company overview covers heating, cooling and hot-water equipment. Its current range combines heat pumps and boilers with hot-water systems, heating controls and connected services.

The aroTHERM plus family addresses both replacement heating and new installations. The outdoor unit works with indoor hydraulic equipment, hot-water storage and system controls. This creates a complete building-heating package, with different arrangements for the property's heat distribution and hot-water requirements. The smart-interface guide describes how compatible systems connect to wider home-energy equipment through local EEBUS or cloud services. The equipment, heating controller and selected connected service together determine how the installation is monitored and managed.

Offering

aroTHERM plus is Vaillant's air-to-water heat-pump family. The outdoor equipment supplies space heating and hot water through matched indoor components. The regional range identifies specific variants and the cylinders, hydraulic modules and controls used with them. In the UK listed-property example, that package includes a uniSTOR cylinder, buffer cylinder, VR 71 wiring centre and sensoCOMFORT system control.

myVAILLANT connect and the interface options provide the connected layer. The guide describes both local EEBUS communication and cloud integration with other energy equipment. EnergiePLUS is a German energy-management service for supported heat-pump systems, scheduling operation around the documented tariff and installation conditions. This separates the installed heating equipment from the optional service that helps determine when it runs. Availability and service terms follow the specific regional offering.

Technology

Vaillant's smart-interface guide distinguishes EEBUS, a local connection between compatible energy devices, from its cloud API. This provides two different integration architectures. A local heat-pump-to-energy-manager connection and an internet service should not be treated as the same endpoint, and the existence of a cloud API does not establish a general Modbus register map.

The EnergiePLUS FAQ states that simultaneous use with a further energy-management system, including one connected through EEBUS, is not possible. Its reason is that multiple systems can affect and disrupt each other. That restriction is material when designing photovoltaic self-consumption, dynamic-tariff scheduling or external monitoring around an existing service. Reading an independent electricity or heat meter is a different activity from sending heating commands. A practical design first identifies the controller and gateway, then assigns a single system to own the supported optimisation commands while retaining clear measurement sources.

Customers

The Lüneburg case study describes a partially renovated 1925 semi-detached house fitted with an aroTHERM plus heat pump. The account identifies existing radiators, a conservatory with underfloor heating, earlier insulation work and an existing photovoltaic installation. It presents the building and heating arrangement together, giving a useful picture of the plant's setting in an older home.

A UK Grade II listed-property case study documents a 12 kW aroTHERM plus, a 250-litre uniSTOR cylinder, a buffer cylinder, a VR 71 wiring centre, sensoCOMFORT and myVAILLANT connect. C.P. Jefferies designed and installed the replacement for an oil-fired boiler system. The account describes noise and the property's appearance as installation considerations, alongside the heating and hot-water requirement. Both examples are manufacturer-published accounts of complete retrofit systems, with the equipment and building context explicitly described.

Company

The Vaillant Group company overview identifies an international family-owned business based in Remscheid, Germany. The history traces its origins to Johann Vaillant's 1874 workshop and lists Vaillant alongside sister brands including Saunier Duval, Glow-worm, Protherm, AWB, Bulex, Hermann Saunier Duval and DemirDöküm. The group develops and manufactures heating, cooling and hot-water equipment for markets around the world.

Vaillant is the heating-equipment brand covered here, with aroTHERM plus among its current heat-pump products and connected interfaces supporting wider energy-system coordination. Its regional businesses combine the appliance range with installer support, service and market-specific connected offerings. The German EnergiePLUS service is one example of that service layer. The common brand and group ownership sit alongside distinct regional product and installation arrangements.
