Jacuzzi not so cuzzi. Could it be just the heater?
Awhile back I got in the tub and noticed that it was not very hot. The digital readout said it was 118.... I got out and dumped the breaker and was going to look into it in the morning witch turned into a few weeks. Now the water is cold. All the pumps will come on, but it wont heat up.... I checked the power coming out of what looks to be a relay to the heater, Its 240. i noticed the wires that connect to it from the heater are a little burnt. I don't want to order a new heater if i don't have to. what are your thoughts?

Sounds like the heating element has gone out again. Once you reset the circuit breaker and the tub turns on it will start to circulate the water. This usually runs like this for about 2 mins and then the tub will recognize it is cold and send power to the heater. If the element is back at that point it will blow the circuit breaker. If this circuit breaker pops as soon as you turn it on then you most likely have a bad circuit board.
Hello, I not sure if your having a problem with your current in-line heater and can't get to it to repair or replace it but, this is the most effective way of heating your tub water without adding water and I say this assuming that the heater is 220 volt and not 115volt. An on demand electric water heater would cost more money to operate then your current unit. A gas on demand heater would not function properly and would fail to provide the hot water you need. If you install a gas on demand water heater and use it to just fill your tub with hot water then you would save money in the long run and be able to use it for your whole house. Hope this information is helpful. If you have more questions please feel free to ask.
all heaters have a thermostat (or multiple) and heating elements.
Start by removing the elements and seeing if they are burnt through. If so, replace.
If they look fine then replace the thermostat(s).
Both are relatively easy and cheap to perform.
Remember to turn off the power and water to the heater and drain the unit completely before doing any servicing.
Depending on how you heat the hot water, whether gas or electric, is a missing detail in your problem, but if it is electric then your problem is the size, being only 40 gal, and needing probably about that to fill the tub, will always lead to your current position.
If the hot water heater is gas, the chances of it keeping up are slightly better, but again things like the temperature of the water leaving the tank, any mixing valves, etc. will effect the water temp at your tub. Before raising any temps, make sure you follow local code, as not to scald yourself or others.
