Depending on the size (volume) of the tank, you should feel the water rise above ambient temperature in as little as 10 - 30 minutes. Hot water should be available in 20 - 60 minutes for electric water heaters - and slightly less for LP / Gas fired heaters.

My water heater shuts down in cold weather. How do I fix this problem


Add tempering tank.
Tempering tank made from old tank-type water heater, or small tank heater will passively heat incoming water.
http://waterheatertimer.org/Tempering-tank.html

This works because tankless can only raise temperature so many degrees. If water is very cold, tankless cannot keep up, so the sensors shut down the unit.
Passively preheating water... or using a small tank connected to power can preheat water enough so tankless works.
Also delime tankless each year will help remove natural scale that builds up inside tankless heat exchanger.

Central heating boiler will not heat heating water


first do not call engineer go up in loft if there is a lot of insulation in loft have some boards to lay down in loft you will have two water tanks one large and a much smaller one look inside the smaller one and if the ball valve is stuck in the upright position and no water in tank move ball up and down water should flow wait for tank to fill then bleed radiators with a small key obtainable at most diy stores for this you will need a small towel with key hold towel under valve loosen the screw at top of radiator air will escape then water will escape do this to all radiators repeat this a second time so only water comes out turn on heating system also there is a chance you will have to turn down heating system

Low boy water heater leaks at point where cold water pipe enters caseing.The leak is below the threads.The caseing is rusted at the point where the pipe goes through.Can this rusted place be patched or...


1) Your water heater needs to be replaced.
It cannot be repaired.
Tanks rust out after anode rod is depleted unless anode is inspected and replaced 1-3 years.
Water softener causes anode to deplete quicker, so inspect every 2 years.
Also stray household current can cause tank to rust out. Put bare copper ground wire between hot and cold pipes on new heater.

2) First thing is protect yourself from tank rupture where water heater bursts open and water runs until it's shut off. Ruptured tanks are big topic in homeowner insurance industry today because they cause major damage inside house.

- Turn off heat source so tank is not under pressure:
Gas: Rotate dial to pilot so pilot light stays lit, but burner does not turn on
Electric: turn off circuit breaker

- Turn off water going into tank using shut off above tank.
- Open hot side to bathtub to relieve pressure from tank.
- Check label on side of tank to get tank specifications for replacement.

3) What to do until replacement.
You can get by for a while on leaking tank by turning it ON only when needed.
Make sure tank is full of water before turning heat source back on.
This will buy time until replacement.
Electric tank heats 21 gallons water per hour.
Gas water heater 41 gallons per hour
Shower uses 6-9 gallons hot water, bath uses 12-15 gallon hot water.

4) Additional reading so next tank lasts longer

HI sorry its shot, they go every now &then.You can run it like you say temporary BUT the boiler needs low pressure to force heat @10 or 12 p.s.i. This pressure will leak out of the hole and you eventaully loose heat & get noise.If you got a pinhole leak in tank.With the main off.Slow it down with duct tape or a rag if you can and leave water on.

Water Too Hot


needs new thermostat(s) If the whole tank is heating( next time it trips, before using any hot water check the lower tank thru the lower element access(breaker off) If the lower tank is hot-you need a new lower thermostat. if just the upper part of the tank is heating -you need an upper thermostat.

Heating elements do not operate together


That's how they work. First you need to know that cold water goes into the tank near the bottom (because of the "dip tube" inside the tank) and hot water is taken out at the top. Also hot water naturally rises.
so... when the tank is full of cold water the top element will come on and heat up the top 1/3 of the water then the bottom element will come on and finish heating the rest of the tank
