WHY USE PIPE INSULATION

 

 

Energy Conservation

 

 

Pipe insulation is also very important for keeping heat in the pipes and ensuring that it is conveyed to its destination without excessive heat loss.  Pipes may run through cold spaces such as garages and roof voids where you don’t want heat loss into these spaces as this will make the heating system less efficient.  There is also good reason to insulate heating pipes running through heated spaces to prevent overheating of rooms within properties.  This way heat is delivered directly to the radiators with thermostatic controls in habitable rooms without excessive losses in circulation areas.  In larger buildings secondary hot water circulation and heating pipes must be insulated to prevent overheating in corridors where pipes are often located as this greatly improves the efficient of the system especially where the hot water heating boiler may not be as efficient as the space heating boiler.  Rule of thumb - the bigger the pipe diameter the thicker the insulation should be for effective insulation.

 

Energy Conservation applications:- Insulation of all pipes in garages and roof voids or other unheated spaces, prevention of overheating by insulating pipes within the building.  Some example pipe heat loss calculations for 22mm copper pipe are; no insulation=61 watts/ meter, 9mm insulation=11.3w/m, 13mm insulation=8.3w/m.  So if you had 10 meters of flow and return pipes in a garage or roof space, your would giving over 600 watts of heating to your garage/ loft which would be wasted energy.

 

 

Frost Protection

 

 

Winter usage of pipe insulation is to protect pipes against frost damage.  All types of pipe can be affected by frost damage, in particular metal pipes such as copper, lead and steel which will readily split upon freezing due to the expansion of freezing water when ice occurs.  When ice bursts a pipe, upon thawing significant damage occurs due to water supply flooding or emptying of the heating system.  As a rule of thumb the thinner the pipe diameter the thicker the pipe insulation should be.

 

Frost protection applications:- external pipes, all loft space pipe work serving tanks or hot/cold an heating water pipes.
