High performance required for Level 4 in the Code for Sustainable Homes
“When combined with the other energy efficiency initiatives in place, PB-1 UFH systems have helped to achieve the performance required and ensure a very low energy requirement of just 13 – 15 kWh for heating.”
– Geoff Mountain - Developer
Located four miles south of Harrogate, the New York Farm re-development includes a new highly-insulated two-storey farmhouse. When developer Geoff Mountain demolished an aging structure to begin construction of a new 560m2 residential building, he required a high performance and flexible heating system that would help the new farmhouse to achieve Level 4 in the Code for Sustainable Homes.
“I have been using Wavin's Hep2O Polybutene-1 underfloor heating systems for a number of years,” commented Geoff Mountain. “When combined with the other energy efficiency initiatives in place, it has helped the building to achieve the performance required and ensured a very low energy requirement of just 13 – 15 kWh for heating.”
Combination of high comfort levels and low running costs
Built using insulated concrete formwork and with a biomass woodchip boiler, the project’s heating system specification would prove crucial to maintaining these high performance standards. The PB-1 underfloor heating system proved ideal, combining high comfort levels and low running costs with a fast, simple and non-intrusive installation.
Comprehensive system using Polybutene-1 piping
Installed throughout the lower ground and ground floors, the underfloor heating system comprises panels, Polybutene-1 piping, manifolds and heating controls. As well as making little difference to the floor depth, they are also lightweight, easy to cut and handle, can withstand point loadings and can be installed by just one person if necessary.
Manufactured and Kitemarked to BS EN ISO 21003, and under a Quality Management System which satisfies BS EN ISO 9000 requirements, Hep2O underfloor heating pipe made from Polybutene-1 is also covered by a 100 year guarantee against defects in material or manufacturing – offering the client total peace of mind.
Zoned heating increases efficiency
On the building’s first floor, a series of radiators was installed and plumbed into a PB-1 underfloor heating manifold. This allows the heating to be zoned as individual rooms to improve the system’s flexibility, improve internal comfort levels and increase energy efficiency to reduce costs. Completing the plumbing and drainage specification, Wavin also supplied a series of soil and waste systems from its OSMA range.
“As a complete package and system, the PB-1 system proved the ideal solution for our farmhouse development,” added Geoff Mountain. “Throughout the project the back-up support from Wavin, and particularly Andrew Redshaw, has been excellent and helped us to overcome any challenges throughout the process – helping to deliver a high performance heating system that will perform for many years to come.”

Polybutene-1 is often referred to as Polybutene, Polybutylene, PB-1 or PB.
Polybutene-1 is not sold by PBPSA members for use in pipe applications intended for use in North America, and those parties require their customers or distributors not to sell products made from PB-1 into pipe applications for North America.
