Join the Pete Project now and help the move to a cleaner, fairer energy system.

What tank support is available following the end of the project?

Once the project finishes on 31st December 2019 the responsibility of maintaining the tank falls to the owner of the tank. Should you encounter any faults with your Mixergy tank, information regarding the tank warranty can be found at 

Where can I find copies of the projects legal agreements?

PDFs of the projects legal agreements can be found at

My tank is connected to the wi-fi but I do not have access to a smart phone or computer, how do I change my schedule?

You can get in touch with Mixergy directly and ask them to manually change your heating schedule. Mixergy can be reached by calling – 01865 884343

What is the standard heating schedule for the Mixergy tanks?

If the tank has never been connected to wifi the controller won’t be able to obtain the time and date, thus not able to run standard heating schedule. It just needs to be connected to the internet once to obtain the time (although it will lose the time if it is being powered off again). Without time, the tank will be in a ‘limp mode’ which maintains the hot water level between 40-50%.

Can I still take part if I do not live in West London or Cornwall?

If you do not live in the Pete Projects installation areas we won’t be able to install a free Mixergy tank for you. However, you can still benefit from the Pete Project as there are 100 tanks that Mixergy are selling at 30% off RRP. To find out more about this offer please contact Mixergy directly either by email – or by phoning 01865 884343

If I need to contact someone about my tank out of hours, who should I call?

There is a 24/7 helpline that you can contact for tank assistance – 0131 513 9534

What will happen to the tank once the trial has finished?

Once the trial has finished your Mixergy hot water tank can either continue to be used as a smart tank whilst being connected to your wifi, or it can revert to a conventional tank.

How long will the trial last for?

The Pete project will run until December 2019.

Can I still sign up if I do not have broadband at home?

We are afraid that if you do not have wi-fi then we will not be able to install a Mixergy tank for you. The Mixergy tanks are reliant on wi-fi so that they can connect to the Mixergy cloud, in turn allowing the user to control the tank via the Mixergy app.

Am I at risk of a cyber-attack if my tank is connected to the internet?

No. The technologies will be communicating through a secured and authenticated channel to our servers.

Why are the tanks be given away for free?

The hot water tanks are novel in their ability to communicate with the National Grid. The Pete Project is funded by the Department for Business, Energy and Industrial Strategy, so we are able to give the tanks away – on condition that you allow us to communicate with the tank once it is installed, and collect data for the trial.

Can I be part of the trial even though I do not have a hot water tank?

No. If you do not have a hot water tank, we cannot fit a tank into your home as the plumbing will be configured in a way that is unsuitable.
