If you’ve ever wondered what OpenTherm actually does, we’ve put together a quick explainer.

Rather than simply switching a boiler on and off, OpenTherm allows compatible heating controls and boilers to communicate with each other, adjusting the boiler’s output to better match the heating demand.

Mistral has OpenTherm built in, alongside a range of other features designed to give installers greater flexibility when it comes to heating and hot water control.

Working in the heating and plumbing industry can mean long days, pressure on site, tight deadlines and, for many, the added demands of running a business.

It can be easy to just keep going.

This World Mental Health Day, take a moment to check in with the people around you. Ask a mate or colleague how they’re doing and take the time to properly listen to the answer.

And if things aren’t feeling right for you, talk to someone too.

Looking after yourself matters just as much as getting the job done.

The first properly cold mornings of the year are starting to arrive, which means heating systems everywhere are suddenly being called back into action.

For homeowners, the best experience is the one they barely notice. The heating comes on when it needs to, the house is comfortable, and they don’t have to give it much thought.

Good heating controls make all the difference.
