You better watch out, you better not cry. We'll upgrade your heating from low-tech to high. Alright, that was awful, but we really do have an early Christmas present on offer this week, and one that's sure to keep you toasty on those bitter winter evenings. Thanks to Tado, we're giving away an entire smart heating system, including the company's latest connected thermostat (which plays nice with Alexa, and will soon support HomeKit), as well as a pair of smart radiator valves for creating independent heating zones. Better yet, free installation is part of the package, leaving you to focus on decorating the tree. As always, you can enter the competition up to three times via the Rafflecopter widget below. After you've scanned the rules, that is.
