Smart Home Energy 
If you've got hot water pipes running through cold spaces or outdoor pipes at risk of freezing, this foam tube cuts heat loss and prevents burst pipes — just measure, cut, glue, and you're done.
Problem it solves
Reduces heat loss from hot water pipes and prevents freezing of cold water pipes by wrapping them in foam insulation, cutting the energy needed to heat water and avoiding burst pipe damage.
Who it's for
Homeowners and renters with exposed pipework in unheated spaces (lofts, garages, outside walls) who want to cut water heating costs or prevent freeze damage in winter.
Why we recommend
An easy win for energy savings, if your pipes are not already lagged.
Savings
- Typical annual saving
- £15–£40/year depending on length of hot pipes insulated and water heating method
