myVAILLANT connect internet gateway  
with heat pumps  
Vaillant heat pumps can be installed with a myVAILLANT connect internet gateway to enable use with the myVAILLANT app. Not only  
can the app provide homeowners with the energy consumption, energy yields and efficiencies of their heating system, but it can  
also enable you to see how your customers heat pump is performing with myVAILLANT Pro Service.  
Monitor your customers systems with myVAILLANT Pro. myVAILLANT Pro Service will show you the energy efficiency of your  
customers heat pump, the energy consumption, heat generated and more. This will enable you to advise your customers on the best  
way they can use their Vaillant heat pump.  
Depending on the heat pump system installed, the VRA 42 or AC adapter three pin plug should be used to power the myVAILLANT  
connect. the VRA 42 can be purchased from your local merchants with a gateway or separately.  
Depending on the heat pump system, either the VRA 42 or AC adapter three pin plug should be used:  
aroTHERM plus  
⬤ with a VWZ MEH 97/6 hydraulic module can use the VRA 42  
⬤ with a VIH QW 190/6 uniTOWER can use the VRA 42

aroTHERM split with either the VWL 57/5 IS, VWL 77/5 IS or VWL

Boiler Plus  
All of Vaillant’s current range of controls or combination of controls exceed the requirements of the Boiler Plus legislation  
introduced in 2018. We have always been proud to provide our customers with the most efficient controls on the market.  
Sustainability and efficiency are at the heart of everything we do.  
What is Boiler Plus?  
Boiler Plus is government legislation that aims to regulate and improve the way homes use energy by increasing the efficiency  
of their heating systems. If you’re looking to update your customers heating system, or simply want to ensure your customer is  
receiving the best efficiency possible, we’ll help you understand the steps necessary to comply with the government regulation, as  
well as answer a number of questions frequently asked on the topic.  
There are a number of ways you can comply with the Boiler Plus regulations. We have outlined the absolute requirements below:  
Your heating system must meet or exceed an Energy Related Products (ErP) efficiency of 92% during operation.  
All installations must have time and temperature controls fitted, if they aren’t already present and working correctly.  
How to comply?  
In addition, combination boilers, which make up a significant proportion of the market will require one of four additional  
requirements to be fitted. It will mean each installation will include a consultancy aspect needed for each boiler swap. The measures  
available are:  
Load compensation - the ability to modulate the flow temperature from the boiler based on the actual room temperature, this  
requires the control and boiler to ‘speak’ the same language.  
Weather compensation - the ability to modulate the flow temperature from the boiler based on the outdoor temperature.  
Smart control - a control that provides automation and optimisation.  
Passive Flue Gas Heat Recovery - a method of preheating a hot water demand by utilising any excess heat in the flue.  
What’s new?  
As of late 2022, Boiler Plus standards have been introduced in Scotland and Wales with some slight differences to those set in  
England.  
Boiler Plus in Wales  
Boiler Plus policy in Wales introduces the requirement for the smart thermostat to also feature remote access.  
For a complete solution that meets the four additional measures of Boiler Plus in Wales, we would recommend pairing an ecoTEC  
exclusive with a sensoHOME or sensoCOMFORT with an internet gateway.  
Boiler Plus in Scotland  
Boiler Plus policy in Scotland meanwhile has been expanded to apply to all gas boiler replacements (so includes system and open  
vent boilers as well as combination).  
Control requirements remain the same as England.

Tested. Secure. Peace of mind.  
Vaillant works with VDE to ensure data is secure  
The VDE institute is an independent and neutral European technical-scientific association that tests and certifies electrotechnical  
devices, components and systems. They test products for their safety, electromagnetic compatibility and other product  
characteristics.  
Products carrying the VDE mark have been independently assessed against international standards and legal protection  
requirements.  
One of the areas the VDE works in is the assessment of products and services for smart home security.  
All of Vaillant’s products have been rigorously tested and have met VDE’s strict testing criteria for approval by the Institute. You can  
therefore rest assured that Vaillant products are secured and protected to the highest level.
