New Vaillant aroTherm Plus in black - When will it come to the UK?

Sandy · 2025-08-07T16:42:57Z

It looks like Vaillant are updating the aroTherm plus line of heat pumps, now in black. Their German website suggests it will be available there in September 2025. Does anyone know when it will be available in the UK? I have an install booked for the end of September and prefer the look of the new one, plus any other improvements it may have, so if it's out anytime soon I may look to delay.

The vaillant controller and app do all of that (and more) natively. Forget any external controller it's just not necessary. Seriously you don't even need (and really shouldn't have) a thermostat (and if you need one the Vaillant wireless controller has a temperature sensor).

From the quotes I got so far, it seems Vaillant is selling what they call the basic pack in terms of controls for over £3k, almost as much as their pump..

What does this include? 3K is well ott. Check midsummer wholesale for a sense check/Calibration.

Vaillant are neither the cheapest nor the most expensive, a good mid market choice for a balance of cost and quality. That doesn't make it the best, just an option seriously worth considering.

Obviously different installers will load things differently which is why shopping around is worthwhile.

The other class of solution I would look at in the 5kW range where you are, is cheapest available homlely compatible unit plus homely. For this option check you are happy with the subset of homely functionality that is cloud independent imho. Homely is obviously optional but your posts suggest you want a fairly good UI with a fair few features.

Also don't forget octopus. If posts on here are anything to go buy their vertical integrated, very slightly dumbed down, approach seems to work. Less opportunity to fiddle though if that matters to you.

4kW peak of solar PV since 2011; EV and a 1930s house which has been partially renovated to improve its efficiency. 7kW Vaillant heat pump.
