My hot water boiler is NOT sending out water relly tht hot.The thermostat is on fully.All the upstirs bath etc

Question

All radiators in each room working perfectly.....except downstairs kitchen sink....tepid water....and those taps are nearest the boiler(gas),Im suspecting the mixer tap is faulty.Will bleeding the radiators make a difference to the teperature of the running water taps??

All taps and rads perfectly in every room EXCEPT the kitchen sink.....the waterflow is ok,but runs tepid.The kithen sink is right next to the combi gas boiler!! Could the kitchen tap be duff??

All taps and rads "run" perfectly except......

Answer 1

Try running the hot water with the taps only half open. The water cominf from the boiler must have a chance to be heated before it is drawn off.

Answer 2

You need to ask a couple of questions more on this problem. When did this problem begin, and what work has been done recently that would open the system to air. The reply about bleeding air from the radiators is good, IF the system has been opened somewhere that would have allowed air into the system. A leak, however small could do the same thing. The cause here is that as the steam condenses, it creates a low pressure area, which could fall below atmospheric pressure and allow air to be drawn into the system, which would impede steam flow. Your system really needs to be kept free of air. It should be air tight, and at a low vacuum of 5 to 10 inches of mercury pressure. This is how vacuum is measured. A Gage calibrated to read vacuum will do this for you. Test the system in several places and compare all of the readings. You could have a blocked pipe that is causing this problem.
Check the operation of the burner. The thermostat may be full up, but if that burner is not producing full flame, that thermostat isn't going to help at all. Another point to check, the circulation pump, is it working properly, if the system has one. Finally, are there any closed valves, or partially closed valves anywhere.

Answer 3

boiler? do you mean a regular water heater? if so, it depends on whether it is electric or gas. if electric, one element is probably fried and the other nearly so. they are not too difficult to replace.

if it is gas, you might have one of a couple of problems. either it isn't getting enough gas flow, or the thermostat is just messed up.

same problems could exist in a boiler that is part of a heating system.

you can replace or repair it, or have it done if you are not comfortable working on such things. You might think about getting one of the new on demand only water heaters installed. they waste no energy keeping the water hot at all times, they heat it only as it is used. they come in natural gas, propane and electric varieties. If you can give me more details as to what kind you have, i can give you more details about figuring out the problem and repairing it. Use [e-mail] for that.

Answer 4

that is in view which you're working off warm water in the past the boiler has had of project to warmth it. The water content of a Combi boiler isn't lots (approximately 4 litres) try working the nice and comfortable water with the nice and comfortable faucets 0.5 open.

Answer 5

Although an issue with the heater itself is most likely, you should also check your water pipes to ensure that there's no issue there. It's possible that the water heater is heating the water to an acceptable temperature but that heat is being lost thanks to uninsulated water pipes or the like.

Answer 6

You may have a blocked air you need a key to bleed your radiators

Answer 7

If its electric then the bottom element is burned out . If its gas then there is too much build up in the tank

Answer 8

look on the hot water tank there should be a regulator of some sort, just turn it up,

Answer 9

It may need a service

Answer 10

try bleeding the radiators
