I just purchased a new 3 level townhouse, and everytime I turn on the hot water it takes 15-20 seconds before the water get’s up to the temperature. Upstairs in the bathrooms it takes even longer: 30-40 seconds. Is this normal? I looked at the water pipes coming out of the boiler, and none of them are insulated. Would it help if I wrapped some insulation around the hot water pipes in my basement (obviously I’m not gonna tear into my walls) Thanks!
It is likely a combination of pipe size, pressure and distance from the boiler and if your pipes are galv. they could be clogged. Check out this website which may offer a solution: http://www.chilipepperapp.com/
Being a new home I would say you dont have galvanized pipes.What you need is a circulating pump installed on the hot water side.Insulating pipes always helps some ,but in your case ,not a lot.Contact a plumber in your area and ask about installing a hot water circulating system.Keep us posted.
