Viessmann heat pumps
Viessmann Vitocal, designed for efficient renovation and new build.
Enerus builds Viessmann Vitocal systems around heat loss, emitter temperatures and real hot-water demand—choosing between wall-mounted and integrated-storage indoor arrangements.
Explore the system routes
A range to navigate—not a model to guess.
Select an option to understand its role. Enerus confirms the final combination from heat loss, design temperatures, hot-water demand, electrical supply, sound and siting.
Vitocal 150-A
An R290 outdoor heat pump paired with a compact wall-mounted indoor hydraulic unit, suited to carefully assessed renovation and new-build projects.
- Final output checked at the design condition
- Hydraulics and electrical supply confirmed
- Sound, airflow and service access assessed
The available output and electrical variant are confirmed from the design data.
Domestic hot water
Vitocal 151-A integrated storage or separate cylinders.
Vitocal 151-A uses an integrated 190-litre class domestic-hot-water cylinder. A Vitocal 150-A arrangement can instead use appropriately selected separate storage where capacity or plant layout demands it.
- Usable capacity and peak household demand
- Coil duty and heat-pump reheat performance
- Standing loss, immersion and pasteurisation strategy
- Dimensions, pipework and service clearances
Controls and connectivity
The controller is part of the heating design.
Weather compensation, schedules and domestic-hot-water priorities are commissioned around the property—not left at generic defaults.
Viessmann control platform
The system interface coordinates heating curves, domestic-hot-water production, schedules and operating status.
ViCare app
Compatible connected systems give homeowners remote temperature, schedule and system-information access.
ViGuide
Viessmann’s professional platform supports setup and commissioning of compatible installations.
App and cloud services depend on compatible hardware, account setup, network coverage and the manufacturer’s current service terms.
The Enerus design process
One team from survey to support.
Calculate the home
Room-by-room heat loss, emitters, hot water, electrical supply and the proposed outdoor position are assessed.
Define the package
Outdoor unit, indoor module, cylinder, controls, hydraulics and installation details become one clear proposal.
Commission and support
Flow, heating curve, schedules and hot-water operation are set up and explained at handover.
Common questions
Viessmann heat-pump FAQs.
What Viessmann heat-pump ranges does this page cover?
The page explains Vitocal 150-A, Vitocal 151-A, Additional Vitocal systems. Enerus confirms the current model and compatibility before quotation.
Which Vitocal output does my home need?
Selection comes from room-by-room heat loss and manufacturer capacity data at the project design temperature and proposed flow temperature—not floor area or the model label alone.
How is the hot-water cylinder selected?
Enerus checks baths, showers, simultaneous use, usable volume, recovery, standing loss, dimensions, water pressure and service access.
Can a Viessmann heat pump work with radiators?
Potentially. Existing radiators are assessed at the intended heat-pump flow temperature and upgraded where their available output is insufficient.
Can the system be controlled remotely?
Remote features depend on the selected controller, gateway, internet connection, firmware and service availability. The exact functions are confirmed in the proposed package.
Could the installation qualify for the Boiler Upgrade Scheme?
Eligibility depends on the property, installation, installer and scheme conditions current at the time of application.
