I have just moved into a house with a Patrol WH7 water heater controller and have no information on how it works. Please could anyone provide any help/advice... is there a manual I can refer to? I don't want to run it during the peak period in the daytime and just need it on for a few hours overnight? Also, can someone explain how the 'boost' works? Please help?

SOURCE: Hot Water Heater in 1991 Pace Arrow RV is not working

If you look on the outside of the RV, you will find the vent for the water heater behind and access door. There usually is a drain plug and valve located as well. Generally they will be tucked away under the kitchen sink area with internal access as well. You will need to find where the valve that shuts the water off to the unit is and turn it on. Most times the water heater is either electric or propane. But sometimes they are only propane. Once your find the access door, you will know where the water heater is. You can also contact Fleetwood who makes the Pace Arrow to see if they have any information on your unit. Usually your unit info or trim number will be located on a little plaque right by the entrance to the RV. You will need this when you contact them. Hope this helps.

SOURCE: Water heater not heating water.

Hi, W/D here.
You'll need an electrical test meter to find what ails ya. The reset button was a good idea, and it may help. If not:
1. Disconnect the power to the water heater (Trip the breaker to "Off").
2. Check the electrodes where they screw into the tank. There are two terminals. Test for continuity. If either electrode tests open, replace it.
3. With power on the heater, test for power through each thermostat to the electrode and back. Replace any defective thermostats.
Hope that this helps you, --W/D--

SOURCE: Tankless water heater not meeting the need

Yes the faucet could be a problem. Try changing for one which you know is ok.
The long run of pipework - each bend, elbow or joint all have a reducing effect on the flow, maybe enough to matter with a restricted outlet. none of this can be altered except by renewing with larger bore pipe - expensive!
Also there should be a dirt filter in the mains water input line/pipe. Try removing & cleaning. Try also removing , reconnecting and then the hot tap [faucet]

The boiler will have an actuator valve which fires it up when a certain flow of water is reached. If the flow is reduced AND the valve is worn, maybe a replacement. Not sure about it's USA construction but in the UK [it's called a diverter valve] many have a rubber diaphragm which is cheap to replace
Check also if it uses a flow sensor switch
Had a look at the Takagi web site and there are pdf's of manuals
Overall I am still thinking that the main prob is in the flow.
Hope I've helped - come back anytime

Troubles with enercare,not able to get satisfaction with getting a new rental hot water tank,no hot water since Aug 31/17

Depending on several things that can and do go wrong, most hot water heaters are fairly simple machines.

You do not mention exactly what is going wrong, only that you are not getting mutch help from enercare (The primary provider of the rental equipment).

Since it is a RENTAL piece of equipment, it is for the rental company to provide the support, if that fails, then there is the Provincil or State agencies that handle contractors and their agents.

Please add some details so that anyone reading this can help.

Specifically the Make and Model.
How big of a house size , and perhaps, try calling the Installers who installed the machine.

usually, there is a number on the front of the heater.

I need to purchase a new heating element. where can I purchase one

Good place to start is contact the manufacturer to see if one is available, and if it's possible to change. If you can provide some detailed information about your water heater such as manufacturer, model, year, size, voltage requirements then we would be able to assist you finding the answer. Not all water heaters are the same so there is no one answer anyone can provide.

My water heater keeps tripping the reset button on one of the two heaters. Anyone know what the problem might be

Reset nice if you gave us a brand/model to go with.
If you mean the small GFCI inside the heater, you'll need to get a Tech Service Call and call Mfrs Tech Support as something is short to ground. This can't be done remotely as you have to track currents and voltages and resistances with a multimeter.
Tankless usually draw less than 2A even when fully on so doubtful you're overloading a general house circuit.
Might even be the small interior GFCI that's bad. That's why you need Tech Support.

Manual for rt25 space heater

If you are looking for the manual to the water heater it should have been included. If you have just moved into a new house with a heater already installed, see if there are previous owner documents. If that doesn't do, the heater should have a tag with a number on it. That is the manufacturer, they should be able to provide a new manual.

The water does not exit out of the container also

Tell me more of what your problem is?
To get water OUT of a Hot Water Heater, you have to push COLD water in-- So the water pressure in the house water system is the moving force that moves Cold water thru the heater, and comes out at the Hot Water Faucet, HOT!

14 month old water heater stopped working

Which water heater do you have??? What is year of manufacture?
Rheem-GE Geo spring hybrid: Rheem-GE heat pump ?? then call GE 888-443-4394 for recommendation of local service technician and expect to pay $400 and do not expect problem to get solved unless area has experienced, certified water-heater-air-conditioning expert.
Installation must be done correctly. For example if water heater is set too close to wall, then service technician will expect you to hire plumber to empty tank and move away from wall and install correctly before repair can resume. It's a nuisance, but this is accurate information based on others who have posted questions.
Copy following link for resources:
There are no service manuals available for homeowner, which is why this product is unwise choice for any installation.
Unit is not protected from power surge. Install one-time-use whole house power surge.
Make sure unit is connected to 240V, and that breaker is not tripped off on one leg. Move wires to another same size breaker. Check wire connections at water heater and confirm 240V.
Check that installation is done correctly as shown on link above.
14 months old means that labor warranty has expired by 2 months. However parts are still covered.
Do not buy expensive water heaters that cannot be repaired easily by homeowner. This single repair can eliminate all anticipated savings from buying product.
If expected heat-pump repair will cost $400, then buy off-the-shelf electric water heater from Lowes for $250 and save the expensive repair.

You have gas water heater.
Probably a tank-type gas water heater.

The plumber can fix water heater.
If you want to fix water heater yourself, then more information is needed to narrow down scope of answer.
1) Add a comment for possible help.
Instructions for lighting the water heater appear on front of water heater. Do those instructions include lighting the pilot light?
Will the pilot light stay lit?
On side of tank is a label. Label shows Brand, type (LP or NG), and model number.
This information can help narrow the type of gas control valve, and point direction for troubleshoot.
Add a comment with this information for possible help.

2) Do-it-yourself: Open following link for do-it-yourself resources to help solve gas water heater problems:
Generally the instructions show how to clean water heater parts, check venting, and show different types of gas controls, plus links for pilot light problems and cleaning air intake.

Relighting the pilot of any water heater is a pain. The first thing to do is call the water heaters manufacturer for information on your specific make and model. If your water heater is under warranty, they will provide technical advice and free parts.
1. Replace the water heater's thermocouple. Make sure the pilot flame is centered on the shiny end of the thermocouple; it requires a certain amount of heat to produce enough electricity to open the main gas control valve.
2. Replace the main gas valve control.
3. Replace the water heater; I know this not what anyone wants hear.
