Making the difference….

Pre Insulated

District Heating


At Flexenergy, we’ve been working alongside consulting engineers, energy managers and contractors for over 30 years, helping to optimise the efficiency of pre-insulated pipe networks serving heating and hot and chilled water distribution systems.

Our position as the sole distributor in the UK and Ireland of Flexalen pre-insulated pipe technology, manufactured by Thermaflex, makes us a valued partner for designers and specifiers focused on system performance, environmental impact and return on investment.

Our low carbon polybutene pipe technology delivers heat loss benefits and energy efficiency gains to district heating schemes and to sustainable energy projects, such as biomass CHP, geothermal and heat recovery networks.

Now, we’re rolling out a unique pre-insulated valve system – V-Flex – that will introduce new levels of control to district and community heating schemes, enabling sectors to be easily isolated for maintenance and network extension.

To find out more about how we can help you, take a look at what we do and then give us a call.  We’d be delighted to work with you on your next project.
