SOURCE: Have a back boiler. Central heating working fine. Hot water not.

Depends on type of control system but usually you will have a three-way motorised valve somewhere. This is contolled by the tiimer and the thermostat on your cylinder. Look for a box that has one pipe going in to it and two further pipes coming out. I suspect yours is stuck on heating. Some models had a manual lever to put it to just hot water. End of the fday you need to get someone out to fix this one.

SOURCE: boiler working hot water, but no heating,. i have

Hi,
In most cases problems with the circulator pump boil down to two problems.
The most common is air in the lines causing an air lock.
The next problem is that the pump gets stuck and is not running even though itmay be hot and seem to be running. In this cause the pump can sometimes betaken apart, cleaned and it will work, but usually it needs to be replaced.

Here is a tip that I wrote that will explain circulator pump problems in moredetail.

My worcester bosch 24i junior pressure keeps dropping if i have heating off for an hour i have to top up boiler and reset also when i have heating on the pressure jumps right up to over 4.0bar


When water is heated it expands. To deal with this all boilers are fitted with a small expansion vessel which is like a reservoir which holds the excess water.

This expansion vessel is like a balloon in a metal pot. When the water goes in the metal pot the baloon squashes a bit to make room for the extra volume of water. When it cools the balloon pushes the water back into the heating system.

What has happened is your expansion vessel no longer works. When the water heats up there is nowhere for it to go so the pressure jumps up to 4 bar. The Worcester boiler lets high pressure water escape (most boiler allow this to go through the safety valve at say 3.5 bar).

When the water cools the pressure drops very low as the volume of water contracts.

The problem is your expansion vessel - normally a little red painted metal cylinder inside the boiler.

Worcester combi gas boiler 3.5 highflow is constantantly dripping water at the external flue position over flow pipe


water vapour is one the main products of combustion of gas. With a standard efficiency boiler, upon initial heat up when the flue is cold this vapour can condensate on the inner wall of the flue but should stop once the flue heats up, to stop this condense dripping back on to the heat exchanger the flue should be tilted towards the outlet and thus on initial heat up water can drip from the flue. with high efficiency (condensing) boilers, condensation will occur in the flue and secondary heat exchanger during normal operation, dispense of this condensate is accommodated for in the boiler and therefor the flue should be tilted towards the boiler, if not the flue will drip constantly.

I need a diagram for an indirect hot water system heated by a solid fuel boiler and an oil boiler


If you are using more than one heat source you will have 1 more pump than the heat source pumps Main pump = SYSTEM pump pumps through the indirect hot water system and back into itself. This is the system loop. The other two boilers tee into this loop upstream of the indirect tank, downstream of the SYSTEM pump. The cold water return to each boiler tees into the system loop next to and upstream of where the hot water for that boiler tees into the system the loop. The oil boiler will have its own pump on its return line from the sytem loop and the solid fuel boiler will have its own pump. When any boiler fires, it turns on its own pump AND the system pump. If you want a drawing email me -pipesster@gmail.com send a fax number and I'll fax you a drawing.

No central heating back boiler


back boiler run from a gas fire? check the instructions to operate the gas heat to the back boiler not just the fire
I presume that this a fully pumped system - air lock doubtful There maybe on/off valves on the pipes to and from the back boiler [situate close to cylinder] make sure they are on - anticlockwise turn
or there could be a blockage in the outlet from header tank usually in the loft. or If there is no water in it maybe the mains cold feed it is off.
Note if no water in it DO NOT USE the back boiler

Very Hot water coming out of overflow pipe


Is your boiler heating your domestic hot water if so i would turn water off to water maker and see if your boiler pressure stays down below 20 psi. If so water maker is bad. The other thing that could cause this problem would be the boiler pump is out.
