Floor heating: Can the pipes leak… and what happens if they do?

Floor heating pipes can only leak if they are cut or punctured – which means someone has to physically drill, cut or penetrate them. They will not burst or leak by themselves (they have a lifespan of up to 100 years, and are extremely durable). Sometimes penetrations do occur by accident on site, however, it is immediately recognised as water squirts out of the penetration (the pipes are pressure tested after installation, and remain pressurised during construction). The pipe can be repaired, and good brands of pipe guarantee their repair even when covered again with concrete.
