Time for change

We all know that the way we heat and power our homes and businesses in the UK has to change. The growing population has put excessive demand on our depleting energy supplies, with conventional heating methods no longer a viable option for many property owners.

The UK’s long term strategy for carbon reduction is to produce more from carbon free energy sources, reducing the demand on our power networks and achieving a 15% generation from renewable sources by 2020.

We are sure you are well aware of this increasing need for change in the UK and although concerned about the global energy crisis you want to ensure that you are investing in the right technology for now and the future.

CTC has been dominant in the Swedish heat pump market for over 30 years, with a proven track record for reliability and performance. Our products have been developed to meet the growing needs of the energy and cost conscious consumer, to fulfil their heating needs in the most efficient way possible.

By integrating CTC renewable heating solutions within your property, you will also be eligible to benefit from the Department of Energy and Climate Change (DECC) Renewable Heat Incentive. The scheme will provide you with a financial payback for producing heat with an efficient or sustainable fuel source, working together to reduce the demand on our power networks.

From product design through to manufacture and distribution; we are passionate about what we do; dedicated to supplying you with quality renewable heating solutions, working together for a sustainable future.

In 2013 CTC celebrates its 90th birthday. To mark this occasion we have invested in our product development to deliver the best performing products we have ever made.

1923-In spring 1923, three young engineers in Göteborg start manufacturing heating products. The company is named CTC after the initials of the founders, Celsius, Tellander and Clarin. The name CTC has since been linked to the Latin phrase “Cum Tentatione Corrigendi” meaning “on-going improvement”. Although this meaning was added later, it is very apt considering CTC boasts almost a century of development and improvement.
