Has anybody got any experience in reducing heat-losses in indoor swimming pools. My main concern is the pool flume which travels outside the building where outside temperature may reduce to slightly below freezing. I am particularly interested in high grade material of construction or types of insulation which may be available but these must be aesthetically pleasing. I would very much appreciate any advice that you might have.
Thank you

Good luck!
RE: Mary Has anybody got any experien
Assuming I understand the question correctly, you are concerned about the flume water freezing?
Lets assume during operation:
1. Flume water supply would be say 29 Deg C?
2. Flume is typical construction enclosed tube GRP
3. Flume is self draining
Water flowing down the flume, at say 28 deg C, over a distance of xx metres thou external tubing would freeze ?
Freezing is likely if external conditions are sub zero, when the flume is not operating (say over night or during maintenance shutdown) the small quanities of water trapped in between the flume joints have the potential to freeze.
Insulation will only slow down this process, you need to work out the exposure time, to size the thickness of insulation or alternately consider trace heating.
Whichever option you chose it must be protected from the elements, otherwise it will become a maintenance nightmare.
Regarding pleasing appearance.........hmmmm.....Ask the flume manufacturer, or another GRP manufacturer to fabricate a "colourful" tubular cladding to fit over the flume tube.
hope this helps

Any help/suggestions you may have would be very much appreciated.

1. Is this existing or new premises?
2. What is the linear length of external section of flume?
3. What are the internal design conditions?
4. What is the night setback?
5. What are exteranl design conditions? when does sub - zero occur ? just overnight?
If the external flume is short, placing a "bung" in the top, will serve little purpose - and will not prevent "wind Tunnel" - convection alone within 1m dia, tube will circulate colder air into the space. And in reality, the staff will forget or loose it inside the first six months.
For heat loss/ gain purposes, the external flume is only an extension of the external wall area, with a much lower thermal resistance - remember without effective insulation condensation will acculumate on the flume surfaces.
