The Climabox story

They say necessity is the mother of invention and the birth of Climabox is no exception. 

Climabox was born five years ago when founder Ehjaz Khan, a heating engineer from Bristol with over 35 years of experience in the industry, realised we could be doing much more with heat pump technology we already have.

It made no sense to Ehjaz that we had all this advanced technology but we were still putting radiators upstairs and then complaining about overheating. 

As he was looking at the peak heat calculations of a new build three bedroom house, the penny dropped. At its peak the house required 3.1kW of heating. But in the summer it needed 5.1kW of cooling. Ehjaz realised modern properties require more cooling than heating, plus lots of ventilation, and knew he had found the solution.

Ehjaz built and installed the first Climabox in his home three years ago. With rave reviews from his family who were astonished by the air quality and levels of comfort, Ehjaz discovered he had inadvertently designed the healthiest home possible.

He asked five more people if they wanted a Climabox in their homes and they all said yes without hesitation, including new build, retrofit and passive homes. That’s when Ehjaz understood exactly what he had in his hands. After all, if it costs you less to run and gives you complete home climate control, why wouldn’t you want it?

Ehjaz was horrified when he heard about Awaab Ishak, the two-year-old boy who tragically died from a respiratory condition linked to prolonged mould exposure in his family’s social housing in Rochdale, England, in 2020. It was a lightbulb moment when he realised that Climabox could also help with mould prevention, potentially saving the lives of children like Awaab and the Climabox Landlord Pack was born.

Climabox is now led by a team of experts in their fields and all equally as passionate about Climabox its world changing potential. We hope you’ll join us in our mission to revolutionise UK properties and make them the healthy places to live and work in that we all deserve.

Our founder Ehjaz Khan

Ehjaz Khan was born in Hazara, Pakistan in 1965. His father, a member of the British Army in the Royal Electrical and Mechanical Engineers, was invited to the UK post WWII by a colonel and moved to the UK before Ehjaz was born.

Ehjaz, his mother and his two brothers joined his father in Brentford, West London when he was 18 months old. At four years old, Ehjaz and his family moved to Bristol, the city he still proudly calls home.

Ehjaz left school and home at 15 and started working odd jobs. Always good at maths in school and with experience working on cars with his dad, he realised he had a knack for engineering. 

After spending time with some heating engineer friends, he found the industry fascinating and knew becoming a heating engineer himself was his next step. He took some courses, worked with his friends, became gas safe registered and started out on his own.

Ehjaz worked independently for five years before he launched his own firm, Pink Heating and Renewables in 2003. He knew renewables were the future and made sure Pink Heating started working with them as soon as they came onto the market 16 years ago.

The idea for Climabox came to him five years ago when he realised we could be doing so much more with heat pump technology than we already do. Our homes have changed, how we heat them has changed, our climate has changed and “central heating” is a term that was coined a hundred years ago.

Fuelled by passion for the industry, a drive to protect the planet and a desire to make sure no more children have to suffer from exposure to damp and mould and poor air quality, Ehjaz is on a mission to make Climabox a household name and UK properties the healthy places to live and work that we all deserve.
