SOURCE: Vaillant turbomax 28 constant hot water problem.

got your fix, its a calcium buildup in the heat exchanger, and more than likely the rest of the unit, you will need to flush the unit with about 4 gallons of vinegar, you will need to recirculate it for about 20 mins through the unit, then flush with clean water, hook it back up, it might take a couple of mins for it to run properly, but it will, I have had the same problem with Rinnai on demand hot water systems, and it worked like a charm, check the filter thats inline as well, make sure it isnt plugged, clean if needed, also if you dont have a soft water system inplace, you might want to think about buying one and having it installed, that will reduce this from happening again for alot longer period of time, hope that helps

SOURCE: my bosh water wizard 10P pilot light keeps going out.

Very possible the thermocoupler is no good. The thermo coupler is that bulb that is in the pilot flame. It controls the main valve It's not expensive and fairly easy to change out.. Make sure you get no dirt in the cspillary tube hole.brass screw end. The bulb must be just in the flame tip when adjusting. Good Luck, Ned-

SOURCE: Natural gas hot water heater not stying lit

Probably a bad solenoid in the gas valve. Higher voltage of a new thermocouple keeps it open longer but it still fails over a period of time. Look into a new gas valve for the water heater.

SOURCE: water heater pilot and burner keep going out.

If this is a common occurrence, then it may be time to replace the thermocouple that controls the pilot part of the gas valve. If it still keep going out, gas valve may be faulty.

Boiler compartment ventilation will not stop you getting hot water . Its sounds like you have problems with a sensor or the water section on the boiler .

Not getting any hot water. Pilot light and burner seem to be working properly. Went from working fine in morning to not working at all this evening.


No hot water anywhere,or just one faucet,doesn't sound right if burner is working,if its coming on then your gas valve/thermostat on front is not working properly.Can be changed,but I would turn up temp. red dial see if she fires and watch to see if she stays on.Gas valve is threaded in and can be changed,depending on warranty.Could also be dip tube is cracked or broken in half,its a tube that forces cold water to bottem of tank,if not working you'll get a real short shower because cold water is in top of tank.Tube can be replaced,its on the cold water fill side which would have to be taken apart.Thinking now its your tube

Heats up the rapidly decreases within in minutes.


Problem new or old? How long you have unit? Sounds like not enough flow to keep burner on. Tankless need at least .6 gpm to keep hot water flowing or else the burner fires then shuts fires then shuts and you get a sandwich effect...hot cold hot cold. If you have new diverter valve in shower -vs- old two handle type try turning hot water ALL the way ON and see if hot stays hot. If it does stay hot then slowly adjust to cool and see if you maintain a good MIX for proper temp. If it goes cold again try this......LOWER control pad setting to a comfortable 105 degrees (ladies) 100 degrees(men) and turn shower valve all the way to HOT. See if your temp remains consistant now and if it does then problem solved. Tankless mindset...set temp on control pad and stop trying to MIX at shower valve. Thats how these things work. Thats why I install a control pad in each bath and one in the kitchen for adjusting ash temp during dishwasher on time. ditto for wash machine. You should never need to turn on cold water if your unit is set to proper temp at controller. Hope this helps

Water Heater Keeps Going Off


is there a check valvle on hot water side of heater,a flow restriction of some sort, water pressure to the heater, a filter in the line, line pressure in the heater kicks out burner, when you turn on the water, line pressure drops, heater comes on, when you turn on water in other part of house, heater should not fire, so there has to be a check valve somewhere,in heater?

you need to change the cartridge, it is a temp control and is going bad so it keeps you from burning yourself it is like a mixing valve and is givng more cold water, that way you don;t get burned,,

Parkray Cumbria efficiency problem


Some circulation pumps have a 3 phase mixing valve (cold,warm,hot) to regulate the water pressure in the building; no way to know unless you trace the plumbing. Basically, the hot water temperature could be lost because the circ-pump is cooling it with the cold water supplied to it. This is used to balance the pressure (aka Pressure Balancing Circ-Pump), so heater is really working overtime to heat the water. If the pump has two in and one out that's more than likely your problem; but you should consult a "old-school" plumber in your area.
