Energy-Efficiency and Cost Savings
With energy bills a major contributing factor to the rising cost of living that we are facing, the Viessmann R290 Hydronic heat pump range delivers

  • Industry-leading energy efficiency with a COP (Coefficient of Performance) up to 5.0 (at A7/W35). In plain English, this means that the Vitocal 150-A range can save you up to 80%* on your energy consumption each year. Viessmann tests to internationally recognised standards, being open and confident about product performance in any condition.
  • Low running costs thanks to Viessmann’s patented Hydro AutoControl® hydraulic system (OptiPerform), which ensures reliable, highly efficient operation throughout the unit’s entire service life.
  • Active cooling** in summer via the built-in cooling function, so one system can heat and cool the home year-round.
  • An integrated energy management system that gives homeowners transparency over energy consumption and running costs, viewable via the ViCare app.

Reliability You Can Trust
Viessmann is a leading German Brand since 1917 with extensive experience designing and manufacturing reliable and durable heating, cooling and hot water technology.

  • Reliability you can trust: the Vitocal 150-A Hydronic Heat Pump is backed by a 5-Year Warranty on all parts and labour.
  • OptiPerform simplifies installation, saving contractor time and your installation costs, while requiring up to 60% less space than comparable systems.

The Benchmark in Sustainability
The Vitocal 150-A range uses the natural refrigerant R290, which has an ultra-low Global Warming Potential (GWP) of 3. This underpins Viessmann’s Climate Protect+++ rating, based on the TEWI (total equivalent warming impact) indicator, which characterises the life cycle efficiency of the appliance and the greenhouse gas potential of the refrigerant used.

A Model for Every Project Application

  • Vitocal 150-A: a hydronic heat pump that offers excellent quality and performance, from the single fan outdoor heat pump in 8kW, and the dual fan outdoor heat pump in 10, 13 and 16 kW outputs. The Standard Hydrobox incorporates all required hydronic heating system components in a single appliance. Ideal for both new builds and retrofit solutions.
  • Vitocal 150-A Compact: incorporates all standard Vitocal 150-A components plus a 190-litre DHW cylinder made of steel with ceraprotect enamelling, for combined space heating and cooling, and domestic hot water in one unit.
  • Vitocal 150-A Hybrid: incorporates all the standard components of the Vitocal 150-A Hydrobox, without the expansion vessel. The Hybrid Hydrobox includes an additional 3/2-way mixing valve for bivalent operation. Recommended for retrofitting existing gas or oil boiler systems.

Smart, Simple, and Intuitive Controls
The Vitocal 150-A range is simple to control via the Viessmann digital platforms:

  • The ViCare App: provides intuitive heating control. Green for go – the user can see at a glance in the app whether their heating system is working as it should.
  • ViGuide App: is for trade partners. It has numerous functions for monitoring and controlling systems in both detached houses and apartment buildings and provides rapid access to Technical Service.
  • Connectivity Inside: is the integrated WiFi interface for operating and servicing systems using Viessmann apps.

Viessmann Vitocal 161-A Really happy I went with Next Cycle for my Viessmann Vitocal 161-A. I'm an installer and I run one of these at home as well, so I had a fair idea what I was after, and the whole process with them was smooth from the first enquiry through to delivery. Communication was good, they answered my questions properly, and the after-sales support has actually been there when I've needed it. The Vitocal 161-A itself has been excellent, quiet, efficient and plenty of hot water, and it's been running with no issues for 6 months. Every customer I've put one in for has been happy too. If you're shopping for a Viessmann R290 hot water heat pump and want a supplier who looks after you, Next Cycle is worth a call.

As an installer I get my Viessmann Vitocal 161-A units through Next Cycle and they've been great to deal with. Stock's been available when I've needed it, the team actually know the product and the rebate side (federal STCs plus the state schemes), and they were upfront about the warranty. The 7-year tank and 5-year parts and labour cover gives my customers real peace of mind. Pricing on the R290 DHW heat pump is competitive and ordering is easy. I've put in [a few] of these hot water heat pumps now, including one at my own home, and every client has been stoked with the result. If you want a Viessmann hot water heat pump and a supplier who backs it up with proper support, give Next Cycle a call.

We recently upgraded our old hot water system and hydronic heating boiler to a Viessmann Vitodens 100 through Next Cycle. Our old system was not reliable and since installing the Viessmann system we couldn’t be happier. Luke and the Viessmann installer were fantastic throughout the entire process — knowledgeable, professional, and really took the time to ensure we were choosing the right boiler for our home. The whole process was smooth and stress-free. Luke went above and beyond after installation, helping us set up the ViCare app and showing us how to use the heating timers and features properly. It’s been about three months since the boiler was installed, and we’re already seeing the difference with noticeably lower gas bills and better overall efficiency. Highly recommend Next Cycle Melbourne, Viessmann, and big thanks for the great service and support!

Highly recommend Next Cycle Fantastic experience with the Next Cycle team. We needed a sustainable hot water solution to replace our old electric unit. They were super knowledgeable, efficient, and friendly. The new system is brilliant—heats up fast and uses barely any power. Big thanks to Jack for explaining everything
