Question about Honeywell Heat/Cool Thermostat

1 Answer

My john wood hot water tank over flows through the relief valve every 3 - 6 months. The hot water is too hot and I can't seem to adjust the Aquastat L4103 on the hot water heater to a good temperature. What should I really be looking at when I am setting the temp? Should I look at the 6 oclock position or the marking on the 10 oclock position????

There should be plate on the front of the hot water heater tank.. Pop that off..
There might be some insilation to move and you should see a set screw for adjusting the temp..
If there are no indications for hotter or cooler - then do a 1/8 turn to a 1/4 turn counter clockwise..

Hope this helps !I
rate me good ;o)

How to change out copper piping from release valve


If the release valve referred to is the pressure release valve, then a water leak out the attached vent pipe is an indication that the valve is failing. To change the valve, the water must be allowed to cool (turn off AC power or gas) and the water level inside the tank must be lowered (drained) to below the level of the pressure relief valve. Once this is accomplished the vent pipe is unscrewed from the relief valve and the pressure relief valve is unscrewed from the water tank. A new pressure relief valve with a sealant on the threads, is then screwed and tightened into place with the outlet port facing downward. The vent pipe is attached to the new valve and the tank refilled with water. A hot water facet must be opened to allow air to exit while filling. Upon becoming full (water will begin to flow from facet), turn off the facet and restore AC power or gas, therefore allowing the water heater to heat up. When the first hot water is utilized there may be some air expelled from the facet.

Adjust water temperature


It is possible that there is an open valve on the back of the water heater which is allowing the hot and cold to mix. Locate the back of the water heater. You will see a water line going into the bottom of the water heater. That is cold water in and there will be a valve on that line. It should be open (The handle inline with the direction of the pipe). At the tope there will be another pipe coming out. That is the hot water out. It may or may not have a valve but if it does make sure that it is open. Then there will be a water line connecting the top and bottom water lines and it will have a valve in it. Make sure that the valve in this line is closed. That is a winterizing bypass valve. If this does not correct the problem let me know and I will give you more steps to consider.

Wickes 102 combi boiler constantly loosing water pressure


It sounds like your thermostat could be the problem. Have you noticed the boiler cutting off at all, or does it run continuously until it goes out on low water?

You stated, "when boiler is on", so I am wondering how you get the boiler on. If your boiler is controlled by a thermostat, you need to check it for a cold draft possibly from behind the thermostat in the wall where the wires come through. The thermostat should never be on an outside wall. The thermostat could be defective.

An aquastat can also control your boiler. If you have an aquastat, check the setting, typically 175 - 180 degrees. You should also have a "high limit" which should be set at 210 - 220. Some people run that high side limit higher; not a good idea - defeats the purpose. If the aquastat is set too high, the boiler will operate too hot and the problem you have will occur.

"pressure rises and pressure relief valve opens" This could mean that your pressure switch is prematurely venting. Check boiler temperature to see exactly at what temperature the T&P valve purges. If it blows off below the high side setting, either adjust or replace. The T&P valves are usually not adjustable. That blow off temperature is stamped on the head of the valve. So, if it discharges too soon, replace it.

Have you actually seen evidence thgat the T&P valve is opening? You may have a bad bladder in your expansion tank and your system may have air in it. Your boiler should have 12 psi when cold and 20 - 22 psi when operating. Check your boiler pressure guage.

"
this eventually drops below the minimum operating pressure" Technically, there is set point for a NO MINIMUM OPERATING PRESSURE. That is a function of the amount of water in the boiler. If the T&P is blowing off, it will vent water from the boiler and the boiler pressure will go down. There is a minimum operating TEMPERATURE.

Your boiler could be low on water. You will have to manually fill the boiler. Be careful of thermal shock to the boiler. Feel the piping, and fill only when the circulator is running. Make sure the water is not going directly into the boiler. The supply water should go into the circulating supply side which feeds the radiators, radiant floor, or base board circuits.

All this will adversely affect your hot water. The heat exchanger for the potable hot water may have scale build up in it. Using the hot water keeps the boiler running, and a scaled heat exchanger will give you cooler hot water and the boiler keeps running. If this is a problem, you will need to replace the heat exchanger. A better idea is to not use the boiler for your domestic hot water. Why run the boiler in the summer?

Adjusting water level on hot water heater


The water heater should be filled to the top at all times, there is no water level adjustment. The relief valve is probably failing and needs replaced.

I don't understand everything being asked, so add a comment any time.

Problem1 is excessive electric bill.
Suspect is new 120Volt Taco recirculation pump.
Look at motor nameplate for amps and watts and HP. Taco pump is usually robust 1/3 HP which is 252 watts or same as running four 60 watt light bulbs.
If pump runs 18 hours per day x 252 watts = 4536 watts or 4.5 Kilowatts per day
Buy a kill-o-watt meter that plugs into outlet, and plug Taco pump into the meter for 48 hours.
This will give you total watts used for that time period.
1000 watts = 1 kilowatt.
Electric bill is probably 12 to 20 cents per kilowatt.
So if Taco uses 4.5 kilowatts per day, that is $.54 to $.90 per day multiplied by 30 days.
So cost is $15 to $30 per month.

Problem2 is Taco runs too long.
Taco operates either by thermostat or by timer. You choose which mode by using slide switch that is usually located under the timer dial. Set switch to TIMER to use timer, and ON to use thermostat, and off to turn TACO off.
If Taco is set for thermostatic operation, the Taco might be defective. Or there could be crossover problem at single handled faucet.
Another problem could be air in the water line: install air vent.

Pressure releif valve leaking


Hot water pressure relief valves serve two functions. The first is to remove high-pressure water from the hot water tank. The second function is to act as a high temperature valve to remove water that exceeds a predetermined point for the valve. Both of these relief settings are preset at the valve factory. Many pressure relief valves will come with a metal tag that identifies these release points. If you're attempting to remove the hot water heater pressure relief valve, pay careful attention to ensure that you replace with the correct valve.

Your hot water heater has a pressure relief valve safety mechanism. When pressure inside the water tank exceeds certain limitations, the valve opens up to allow the pressure to be released. A faulty pressure relief valve will not release excess pressure, which could cause extensive damage to your home. You should test the hot water heater pressure relief valve once every six months to ensure proper operation. If the pressure relief valve fails the test, replace the valve with a new one immediately

Locate the pressure relief valve on your hot water heater. The pressure relief valve has a lever handle on top with a drain pipe attached to it. The pressure relief valve is most often on the side of the water tank toward the top. Newer models of hot water heaters have the pressure relief valve on top of the water tank.

  • Inspect the area around the pressure relief valve for signs of leaking water. If there is leaking water near the relief valve connection, replace the relief valve. If no leaking is evident, proceed with testing the pressure valve.

  • 3

    Examine the area below the pressure relief valve drain pipe. Most water heater closets either have a drain in the floor below the pipe or the pipe is inserted into another pipe to direct the water out of the home. If the end of your drain pipe is not in another pipe or there is no drain in the floor, place a bucket under the drain pipe to catch water when you test the pressure relief valve.

  • 4

    Pull the lever handle on the top of the pressure relief valve up with your fingers. A working lever will lift up without difficulty.You should begin to hear water going through the drain pipe. Slowly release the lever to shut off the pressure relief valve. The pressure relief valve is good. If you did not hear water running through the drain pipe, lower the lever on the pressure relief valve and replace the valve. If the lever is difficult to raise, do not force the lever. Replace the pressure relief valve.


  • Now with all that said if you have a closed loop water supply system and you have a pressure vessal/expantion tank it may have gone bad and is making the TP valve leak. you can call your water provider to see if you have closed loop system.

    We have a brand new rheem 40 gal elec water heater, after installation we have water leaking from the base of the relief valve, pooling up in the plastic fitting and making it way over the side all over...


    Water heater should be set in a drip pan.
    Otherwise, put 1 gallon bucket under TP release pipe to catch water.
    http://waterheatertimer.org/Water-at-bottom-of-water-heater.html#drip-pan

    When you say relief valve, I assum you are talking about brass valve located on top of tank or near top of tank. This is TP valve and a pipe connects to this valve and runs down to within 6" of bottom of tank. TP valve has a small lever on it.
    If you are talking about tank drain valve located at bottom of tank, then add a comment.
    Following information is for TP valve.

    Dripping TP valve can be caused by 3 different thing:

    1) Obstruction inside TP valve. Open TP valve for a moment to flush away particles and slowly lower lever back down. See if water stops dripping, if not, then replace TP valve

    2) Defective TP valve: replace TP valve. Turn off electricity to water heater. Let heater cool for several hours so you do not get scalded. Close shut off valve located above tank on cold side. Open tub spout to relieve pressure, open tank drain or open TP valve and empty water below TP valve level. If TP is located on top of tank, not much water has to be drained. Tank is under press when hot, so be careful. Put teflon tape on new valve and install with big pipe wrench by turning clockwise until TP valve is very tight.

    3) Overheating tank. TP valve is temperature-pressure valve. If tank water is over 150 degrees, the TP valve starts drizzling hot water to relieve tank pressure.
    Lower tank pressure two different ways:
    a) turn down thermostat
    http://waterheatertimer.org/How-to-adjust-water-heater-temperature.html
    b) install expansion tank on incoming cold water line

    Drain pipe from hot water heater leaking on the outside of home ? cause


    Water may be coming from the temperature- pressure (TP) relief valve, which releases water when it senses excess pressure. Excess pressure can be caused by the temperature being set too high, by the main water supply pressure to your house being too strong, or by special valves that reduce water pressure in your water supply system not allowing for hot water expansion in the tank. Or, the TP relief valve itself may be faulty. 20090617111024_hot-water-heater-leaks.gifIf you find the leak is coming from your TP relief valve, consult your owner’s manual for instructions on what to do, or contact an appliance repairperson immediately—if too much pressure builds up, your tank could explode. So, adjust temperature to about 120 deg F , if problem persists, change TP valve.

    Hot water tank shuts down after5 minutes pilot still on water


    Carefully catch some water in a container from pressure relief valve (pull lever slightly) at top of tank, and see if it's up to temperature. If it's hot there, I suspect your by-pass at back of the tank, is faulty. Depending on what by-pass system your using, it may be in wrong position, blocked, or mixing hot and cold. Cold water flows into bottom of tank, and hot out the top. If any valve in between the 2 lines, close it, and make sure valves in and out of bottom and top are open. Let me know what you find, or if water from pressure relief valve is not hot either.
