ximises return efficiency, lowering greenhouse of a system and many people Young, application manager for proof polyethylene, to provide flexibility and resistance to burial loads due to its corrugated profile. Ease of installation is also an important consideration, so fittings that do not require the use of welding or specialist tools are a ‘must’. As a key player in the local heat distribution market, Uponor has a wide range of pre-insulated pipe for hot and cold water distribution that ticks all these boxes. To get the best performance out of the pre-insulated pipe, the importance of correct installation should not be overlooked. The outer jacket needs to be fully waterproof to prevent moisture ingress and subsequent deterioration of the insulation foam, yet robust enough to withstand buried loads. Bedding the pipe in fine grain sand, or pea gravel, ensures the outer jacket is protected from stone impingement. Ideally, you would install the strongest pipe available to you in order to offer the best protection and Uponor offers a range of pre-insulated pipe which is independently verified to withstand static loads up to 60 tonnes when buried as shallow as half a metre or as deep as six metres. Again systems which use low quality or improvised insulated pipes are typically not strong enough to withstand these types of load, which causes compresses of the insulation foam and subsequent reduction in heat retention properties. PRE-INSULATING THE FUTURE In summary, failing to install properly insulated pipework can negate the energy saving benefits of renewable heating systems such as those using biomass boilers and heat pumps. Homemade or cheap alternatives may appear a ‘quick fix’ to get the job up and running but in reality such products are a false economy and highly likely to give performance issues in the future, resulting in costly remediation work. Given the government’s efforts to have 15% of all energy generated from renewable sources by 2020, the market for these types of installations will continue to grow across both domestic and commercial sectors. End-users have the potential to make significant reductions in their energy consumption and monthly bills by switching from fossil fuels to renewable technologies. However, these savings can only be realised in full if the system is used in conjunction with properly insulated and certified pipework from a reputable supplier.
