My hot water is an inconsistent temp between the sink to the tub. How can I adjust the tub to be hotter?

Answer 1

If you live in a single family dwelling, you most likely have one water heater. The water heater heats water and keeps it warm, storing it in tank until you use it. The water in this tank is the same water that comes out your sink faucet and your tub faucet. You can adjust how hot the water heater heats your water by turning a knob on the water heater.

Check and see if you're living somewhere that, for some strange reason, has 2 different water heaters controling what comes out of your sink vs. your tub. Maybe it's an apartment complex with a strange configuration. If this is the case, you'll have to adjust the knobs until they both come out the same.

Another possibility is that there is a longer run of pipe going from your water heater to your tub vs. your sink. Whichever water is the coldest should have the longest way to travel from the water heater, thus the water is cool it while it's in the pipe if this is the issue. I would then suggest insulating the pipes coming out of your water heater so that you're not loosing heat as it travels through the pipe.

The only other reason I can think of would be if you have cold water mixing with the hot water on one of these faucets, thereby reducing the temperature on one of them. You could fix this by changing your fixtures.

Answer 2

When you fill the tub with a mix of the hot water tap turned on and the cold water tap turned on, then turn on cold water less or start by turning on hot and letting it run for a while before putting in the tub stopper.

Another thought if you are living in a house with access to the pipes is to get snap on rubber-foam insulation for the hot water pipes and put it over the ones going to the tub.

Answer 3

Most likely you have a "Tankless" hot water heater as part of your boiler. this type of heater heats water as it flows through the heating coil. When using a sink, the water flow is much slower than it is when filling the bathtub. the tankless can maintain temperature with the flow for the sink but not with the flow for the tub. I had this problem and had an external tank that uses the hot water from the boiler to heat the water in the tank. Now we have plenty of hot water, the problem is gone

Answer 4

How many feet from sink to tub,is pipe exposed to colder temp.? If so,Try installing foam insulating foam wrap on pipe avail at hardware- type stores.A long run or exposure to colder air will suffer heat loss.Very true in mobile-type homes and crall-space homes. Also see if full volume flow is available.Lastly,old hot water tank,ever been drained of sediment?

Answer 5

Hi,

It is possible that your tub has a facet that has a anti scold valve in it? I dunno, you will have to look up the manufacture name and model number. If you do have this type facet installed. Most of them can be adjusted for the high temperature coming out of spigot.
