Pre-Insulated Pipe

LoCO2 Heat are pre-insulated pipe and district heating specialists, and have direct relationships with the following pipe suppliers; Rehau, Uponor and CPV in Pex, copper and stainless steel.

We specialise in the supply of underground pre-insulated pipe and fittings for heat distribution and cooling networks. It also commonly gets referred to as underground heat main or district heating pipe, but whatever you decide to call it, we supply it.

District Heating Networks

District heating networks are the most common use for pre-insulated pipe. This is essentially where a single centralised heat source such as a biomass boiler, is used to heat multiple buildings as opposed to using single boilers in each. Here, pre-insulated pipe is used to connect the single heat source to multiple buildings to provide all the heat and hot water requirements. District heating networks have become increasingly popular, with many new build estates heated via this sort of network as not only can the capital cost overall be less, but it is considered a more efficient way of heating buildings so lowers operation cost and helps minimise carbon emissions.
