Dear Friends,
Please share your experience if you have ever used pre insulated high density polyethylene pipes for chilled or hot water systems. Are they a better choice over conventional black steel pipe in terms of cost, installation and being more energy efficient. Thanks
Hi Folks,
Talking about boiler room safety, is it by law that CO sensor should be interlocked with boiler so that in case any CO is detected inside the boiler room, boiler gets shut down. Secondly what is the minimum acceptable ppm concentration of CO exceeding which may set off the alarm. Thanks
