View Full Version : What temp is your hot water?

My mat's hot water system is a natural gas fired hot water heater with a holding tank. What temperature should the hot water be? I'm trying to keep that delicate balance between keeping the gas bill down and keeping the water hot enough to please the customers.

Never have your hot water over 140, as that presents a scalding hazard. Most keep hot water around 120 and that should be more than adequate for most applications. I have heard there are some crazy locations in California where they actually come inspect hot water temp and fine you if it is below (I think the number was) 125 degrees - but that is very unusual.

I've always heard 120 as the 'norm' Thats what my new water heater set-up was based on.

Thanks for the info, mine is close to 120.

You should check the temp at the washers. Older mats that have been upgraded with higher efficiency equipment might only have warm water at the washers. Large water lines with washers that use little hot water tend to cool while sitting in the pipes. Busy days should not be a problem, but other days the water may only be warm.
I recirculate my hot water so the customer will always get 120 degree hot water.

if you really want to make your customers HAPPY, set 130, otherwise, just 120 should be fine ( I think some of W.H has minimum set as 120) :D

In my mat I am set at 130, I was at 140 for a week and I agree it was too hot for the sinks in the bath room as well the laundry tubs ,so cut it back to 130
