Problem with stove heating

niallo32

I have a dual heating system.

1. A new Greenstar gas boiler - heats all rads without issue.
2. A Stanley Erin Boiler Stove.

The Stove has been installed a few months now but am only really using it the last few weeks.

Up to yesterday evening, it heated all the rads within a few minutes of being lit and all rads and water were very hot.

Last night I light the stove and it took about 90 minutes for the rads to get tepid, I checked the pump next to the stove and all the pipes were cold though the stove itself was very hot and the pump was working. The Pipe stat next to the pump is set to 65c.

The rads never got any hotter than tepid even though the stove was blazing for about three hours.

I haven't changed anything that I'm aware of. I've lit it again tonight and all rads up & down are tepid again.

Can anyone assist?

Thanks

Is pump on flow or return and ditto with stat.

When it worked before had the gas been on also of before?

How do u know pump is working, maybe it is jammed with debris in pipework

Not sure about the answers to the pump or stat - neither have been touched and heating was working until yesterday - I lit the stove yesterday morning and all rads were piping hot.

I removed the panel to look at the pump and ensure it was working - I could hear it working and when I turned the temperature down on the pipe stat, it knocked off, so I turned it back to 65c

The one thing that strikes me is that if the rads were piping hot in a few mins, it certainly wasn't coming from the stove. They were getting their heat from somewhere else.

In fact, the experience you have had most recently with the rads being tepid would strike me as being more typical of the Staley Erin.

try setting the stat lower and see what happens, once it gets going you could raise it again.

I am wondering do u have some non return valve somewhere to stop the boiler acting as a rad when gas is on and no fire.

Does the water boil in the stove if pump doesn't come on?

I had it set to 45c last night and the same thing happened.

The water does heat normally and it heated last night somewhat.

The pipes going into the cylinder upstairs are luke warm now after three hours of the stove being lit.

There is a valve going into the cylinder and up to now, I've had to manually open this and then all the rads heated up nearly instantly.

I've tried leaving this as 'auto' and open since last night to no avail.

Your pipestat should switch the pump on when you turn it down and off when you turn it up and exceed the actual pipe temperature.It may be wired in reverse which would leave the pump running constantly and not give the stove a chance to heat the water.

Would it be possible to post us up some photos of hotpress and stove pipework? Could you photo this valve as well?

I can't imagine any stove heating the rads within minutes. Mine takes around 1 hour.

There may be trapped air in the pipework?

When I turn the pipestat down say below 30, the pump goes off.

I can turn it up as high as it will go and it wont turn off.

The problem is though is that the stove has heated all the rads without issue up until yesterday morning.

The valve in your hot press must be on the gas boiler feed to the cylinder. By opening it manually you fired the boiler hence the heat in the rads.

This is not right. Have your thermostat wiring checked.:cool:

Maybe I'm exaggerating - upstairs rads heated pretty quick, then I've had issues with the valve and as soon as I'd change that to open, the downstairs rads would heat nearly right away.

Here's a pic of the hot press. I'll try and get at the stove pipework soon.

I'll get that fixed tomorrow. The electrician who wired it lives across the road!.

Apologies Mods,bad start, have just seen stove sticky but I went straight into this thread. Mea Culpa.

Here are the pipes behind the stove along with the pump and stat.
