More info about your system please

Do you have a pump?
Do you have motorized valves - how many?
Do you have a cylinder thermostat?

Corroded Diaphragm?

I have a pump for my heating,But dont have a cylinder thermostat...Not too sure about the motorized valves??

Does the pump do just the heating and are there separate larger pipes from boiler to hot water cylinder?

Motorized valves:

Corroded Diaphragm?

On a back boiler?

 

[snadin]

There are no motorized valves...The pump does my hot water as well as the heating...There are larger pipes coming from the hot water cylinder

if there are no motorised vales, then when heating is on, you will also get hot water and vice versa-not very confortable!

basically.. you could have a faulty cyinder thermostat (like i have)! or it may just be turned down - check it is set to 60 degrees

So the pipe, after the pump, has two branches; one branch goes to the radiators, the other goes into the side of the HW cylinder?

How do you turn the heating off when you only want hot water, i.e in the summer?

 

[snadin]

To just set it to water only,I turn the dial to water on,Heating off

 

[jackecole]

the dial on what - a timer???

most systems have at LEAST 1 motorised valve (on the heating circuit,) to stop rads warming up in summer when you ony want hot water!

 

[snadin]

Yes on the timer......sorry i cant be more helpful,Not an expert on these things

Can you confirm that I am correct about this?

 

[snadin]
