No heat in upstairs rads using a newly installed stove (back boiler)

flop

Hi all,

I had a Carrig Mor Stove fitted in the past two weeks. Tonight i lit the stove for the first time proper (I had a 30min demo of the stove right after the stove was fitted), the fire has been burning since 7pm but all the rads are stone cold upstairs however the downstairs rads are all piping hot. Any ideas why this would be the case?

The stove was fitted with a pump and thermostat, which the plumber recommended i have set to 50 degrees when the fire is lighting.

I used the my oil CH this morning and the upstairs rads were hot so i know they rads are working and not full of air.

While I plan to get to the bottom of it with the plumber who installed the system, as i am a plumbing noob, i'd like to get a 2nd opinion so at least i can tell if the plumber is feeding me a line.

Cheers

Are there thermostats or controls that are applied to the circuit for example upstairs downstairs zones.

flop

No. There are two Thermostats

1) One for the Stove: which is located is in the sitting room just away from the stove.

2) Oil FCH: which is located in the hallway. (That' s set to 21C btw)

If all is correct that you have stated. There is some kind of restriction to the upstairs circuit from the stove.I really could not say what it is without seeing a photo of the stove pipework coming from the boiler flow and return pipes.

flop

I've uploaded some photos of the pipework downstairs and upstairs.

I CANT MAKE MUCH OOUT OF THEM PHOTOS. TURN OF THE BALANCING VALVE IN THE HOTPRESS. THE CYLINDER MAYBE ROBBING THE WATER. THATS THE ONE IN YOUR PHOTO 172713 OF THE CYLINDER.TURN IT TO THE RIGHT TO TURN IT OFF.IS THAT CYLINDER UPSTAIRS?

flop

Yes the Cylinder is upstairs. I'll light a fire tomorrow and turn off the value and let you know how i get on.

Thanks

IF THE CYLINDER IS BEEN HEATED BY THE STOVE.
I WOULD SAY IT COULD BE THAT. IT COULD BE BY PASSING THE RADS AND JUST PUMPING VIA THE CYLINDER. HOWEVER IF THE CYLINDER COIL IS TURNED OFF. IT WILL HAVE TO PUMP TO THE RADS. LET ME KNOW HOW YOU GOT ON WITH THAT.

maddragon

I'ld say MarcA is right. The cylinder is probably robbing the rads. Also, check and make sure the stove isn't pitching all the hot water into the storage tank in the attic.

flop

We've had good weather here for the past two days. So i'd not had to light the stove for the past couple of evening.

Once i get a fire going i'll try out the suggestions you mentioned.

Thanks

keep us updated. because if that does not work.only probably one other explanation as long as theres no restrictions.

Just read this article tonight, sounds very strange that all the radiators upstairs are working with oil fired ch and not from pump from stove. would usually find that radiators tend to heat easier and quicker upstairs first rather than downstairs. Maybe it is the cylinder robbing the hot water but I would have thought that it would then be the same for the oil fired ch in that case. I wonder is there any electric valves coming on when the oil ch is coming on? is there a control on oil ch to just have it heat hot water only?

THEY ARE DIFFERENT BOILERS.EXAMPLE OIL BOILERS BROKEN AND STOVE IS WORKING.......HEY PRESTO USE THE STOVE

YOU ARE CORRECT HEAT RISES AND IN THEORY RADS UPSTAIRS SHOULD HEAT FIRST...BUT "THEORY" PEN DOES NOT REFUSE INK

BOTH (OIL & STOVE) SYSTEMS ARE CONNECTED DIFFERENTLY TO THE SYSTEM. SO THE HEAT CAN BE LOST TO A BIGGER APPLIANCE OUTLET.

Hi folks,

Had the stove lighting from 6pm, downstairs rads are pumping hot but upstairs rads are stone cold.

I have turned the red valve (the horizontal to the left of the Hot water tank in the photos) in the hot press fully to the right prior to lighting the fire.

Any ideas what i can try next? Would shutting off all the rads downstairs help? (just to see if they are taking all the hot water)

sounds like a either upstairs rads are not connected or stove pipeed into the wrong side of a motorised valve in the hotpress if ther is one either way u need ur plomber back but 4 now u should turn on ur oil heating but turn stat on oil boiler down as low as it can go so it wil stay off or go off fast then c is stove heating up rads if yes its the 2nd suggestion.also there should not be a balancing valve or any valve on the pipes from the stove to the clyinder very dangerous ur stove could bust if pump breaks down.

DoneDL

As johnjoe 123 has suggested I would try manually opening the valve upstairs but you need to turn off the electricity to the oil boiler as a manual reset willl turn on the oil boiler. If the upstairs heats the pipework needs altering.

It could be a motorised valve upstairs not properly linked in to open for the stove stat . That would be my first port of call .

Our plumber told us that our pipe stat should be set at not more than 30 degrees, maybe try turning down your pipe stat to 30 degrees
