New house - hot water takes too long?

We just moved into our new house... Was just built,but we find that the warm and hot water take about 30 second too get there I've adjusted. Water heater for 140 but did not do much...any help would be appreciated thanksNew house - hot water takes too long?
Move the bathroom and kitchen sink closer to the hot water heater.New house - hot water takes too long?
That is determined by the piped distance between the hot water heater and the spigot you are using. Longer pipes take longer time for heated water to get to you.


If this is a problem you really need to address (most people do not) then you can add an auxiliary water heater unit closer to the room needed. I had a house that took a little longer than that. When I remodeled the house I moved the water heater closer to the bathroom. Some may have a situation where that is not feasible though.
Here are a couple possible reasons. 1) The faucett is just far from the water heater and it takes time to get there. if so you need to add a re- circulation line on your water heater.Basically it is another pipe that will tie into your existing hot water pipe farthest away from your water heater. Then will run back to your water heater and tie in down low usually the drain valve is removed for this process. with a small bronze body circulating pump. Plug pump into a timer so it only runs when you require it most. 2) you live in a cold climate and the hot water supply pipe is un- insulated
That's the result of long runs between the water heater and the tap. If the water lines are over the ceiling and accessable, then you can insulate them with foam sleeves. If they are under a concrete slab then I'm afraid there's not much you can do.


You can install a recirculating pump which constantly keeps hot water flowing between the heater and tap, but that wastes energy.
You have to realize that your hot water pipes cool down when not in use. so the whole pipe from your hot water heater to the faucet is filled with cold water all that water has to be drained out before you get hot water.





They do make systems that keeps the water circulating and hot all the time this will save water but wastes energy. if you can insulate your hotwater pipes this will reduce the wasted energy. If you have city water you will probably balance out between wasted water and wasted energy from hot water.





This may not work on tankless hot water tanks.





I would start by insulating your hotwater pipes this will keep the hotwater in the pipes hotter but after an hour it will be back to room temp.

you install this circulator pump at the hotwater heater and the automatic mixing valves at the faucets (connects hot water to cold water) or add return piping back to the circulator. if the pipes are in the walls this will be hard.
all the previous four answer are correct but your saying 30 seconds is to long,so must be talking tap. install a insinkarator which provides a minimumof 180 degree water right now or a electric instantaneous heater in line or at the closest fixture in question
