This is a recent project that we carried out for the Hampshire County Council over the summer holidays. We installed a completely new pre-insulated heating system for which we undertook all the excavation works, installation of all the below ground pipework and subsequent reinstatement. This kind of installation has become far more common in recent years, with uses such as district heating systems which utilise one common boiler system to provide multiple houses or entire schools with both heating and hot water.
There are many types of pre-insulated pipework, which use various methods of jointing. In this instance we have used Flexenergy pipework, which you can see in this set of pictures. Flexenergy pipework uses a method of electro fusion to heat a metal coil inside the fitting. This, in turn, melts and seals the joint and actually makes it stronger than the pipe itself (when installed correctly that is). Other methods include mechanical jointing with some requiring specialist equipment for the process. Over the years we have installed most of the variations, which all have their pros and cons.
For all emergency leak repairs, both internal and external, on your water or gas on the consumer side of the primary meter, please call: 01243 864765 and one of our engineers will swiftly assess the situation.
