Vian Power Air Source Heat Pump Review

Vian Power Air Source Heat Pumps come in 4 different models.

  • Vian Power S7 Plus Heat Pump
  • Vian Power c5 Heat Pump
  • Vian Power S9 Hear Pump
  • Vian Power C5 Plus Heat Pump

In this article, we will take a look at this range and analyse the pros and the cons of this new Air Source Heat Pump.

 

What is the Vian Power Air Source Heat Pump Range?

The Vian power Air Source Heat Pump Range is a new range of Air Source Heat Pumps. Specifically targeted at the UK and European market for retrofit Hot Tubs and Swim Spas, the range of air source heat pumps comes in 4 different models.

They are available in 5KW, 7KW and 9KW models and there are two different options – “Standard” or “Plus”.

Unlike the “mini” range of Air Source Heat Pumps, these are mode comparable with the Comfortline range that you know I am very enamoured too on this blog and my YouTube Channel.

They do require hard cabling into your mains supply so you will perhaps need to consult an electrician for the work (or just power it off your Spa Pack main block and disconnect your electric heater 😉 )

In terms of the units themselves, they come with a titanium heat exchanger which is a nice touch as too is the temperature rating right down to -10C for the Plus models and -5C for the standard range.

What is incredibly nice of the manufacturer is to actually state the COPs all the way down to the -10C range. This is certainly something that is not common and very much welcome. You can see exactly what kind of levels of performance you are going to be taking about.

What is the difference between the “Plus” and “Standard Models” models?

There are two main differences between the plus and the standard models. Firstly, the plus models are rated to a lower temperature -10C whereas the Standard models are only rated to -5C.

Secondly, the standard models are “on/off” models whereas the “plus” models are fully inverted. The difference here means that the standard models will be running at 100% all the time regardless of the temperature setting and ambient temperatures.

A fully inverted model can calculate that it might only need to run at 67% for example to achieve the temperature that it has been set to given the ambient temperature.

In short, fully inverted models are more efficient than on/off models.

What are the standout features of the Vian Power Air Source Heat Pumps?

I think that the COPs (Coefficient of Performance) that are on offer for these models is pretty good indeed. If we take the middle of the road 7KW at 25C we are looking at a COP of almost 11 and at 0C 4.5 which is pretty good indeed. Even at -10C you are still going to get 3.5x the amount of electric in out in terms of heat. Pretty good indeed.

All units as you would expect can heat up to 40C which is a given if you are running a hot tub.

The titanium heat exchanger is also good for longevity although these days, this seems to be somewhat standard even in cheaper Air Source Heat Pumps.

This is a true all season Air Source Heat Pump given the temperature rating of this Air Source Heat Pump.

How have the Vian Power Air Source Heat Pumps Been tested in the field?

When I first saw this product, I did call the manufacturer for more info and to get the inside scoop. I was told that they had over 100 of these units deployed for over a year in the field for testing before they were planning to launch this model.

According to them, the feedback from the “testers” was really positive indeed which gave them no concerns to launch this to the mass market. They also had a number of pre-order for the model too which again is encouraging.

What is the temperature rating of the Vian Power Air Source Heat Pumps?

This range of air source heat pumps will operate from -10C for the plus range, and -5C for the standard up to +43C. That is quite a large operating temperature range indeed for an Air Source Heat Pump.

How do I connect a Vian Power Air Source Heat Pump  to my existing hot tub?

The first thing that you are going to need to do with your Vian Power Air Source Heat Pump  is find a suitable location to cut into the pipework on your hot tub. Ideally, you are looking to add the Air Source just before, or just after the circulation pump.

Below shows the ideal location to cut the pipes on this particular hot tub.

Next, you are going to want to use one of the connection kits that I have prepared. They come with everything you need in order to connect them to your existing tub.

Just be mindful of the direction of flow. The front of the pump is always suction.

When is the Vian Power Heat Pump Range Available?

According to the manufacturer, this model will be in stock for the UK and Europe from mid-February 2023.

Which countries are the Vian power range of Air Source Heat Pumps Available?

This range of Air Source Heat Pumps is available in the UK and Europe.
