Stanley Erin stove not heating radiators

tradman

Just moved into a new place and the Stanley Erin stove has been in about 4 years. Lovely heat from it but the rads are only luke warm at best. It heats the water grand. I am burning briquettes and logs. The thermostat is set at 50 degrees. Any ideas - don't want to turn on the oil or put on a jumper just need to get the rads going. Thanks !

is there a valve arrangement where you can divert the heat from the water to the rads? Pump running correctly?

Pump is running correctly. There is no valve for redirecting specifically. It does heat some of the rads but only barely warm

Is the pipe stat fitted on the return pipework of the cylinder? (The pipe leaving the bottom coil connection) If it is I would unclip the pipe stat and fit it on the flow pipework to the cylinder coil as it would give more priority to heating rather than hot water. Set the pipe stat at 45 degrees. This pipe stat turns the pump on and off.
How many rads are you running and how many doubles? If they are many big doubles it may not heat them all. To give you an idea a 45,000btu 13kw boiler stove would only run hot water and only 5 600X 1000 double convector radiators.

Is the wood well seasoned and very dry?
What is the draw on the chimney like?

The Hurricane

Try Ecobrite its a solid fuel product for stoves and is manufactured in Ireland by Arigna fuels it will heat radiators very well. The other thing to do is get the radiators flushed out they get a lot of blockages with the same water being pumped round all the time. The erin stove heats 14 radiators in our offices that are not that well insullated they burn ecobrite there. if neither of these work try and get the original plumber to look at stove to see what the problem is to see if Stove fan suggested to see if the thermostat is on the wrong pipe.

I have a erin stove here too and its been here for years never really any majors problems with it. But recently I have noticed the rads stay warm for longer even if stove is only smoulding but the water is barely luke warm now. So to summarise. Rads would heat up and cool down when stove stops blazing but water was hot. Now rads stay warm for longer but water barely heats. I didn't do anything except adjust the thermostat and thats at 50 at the moment.

Ther thermostat is located on the pipe that comes from the top/back of the stove. The pipe that goes to the cylinder (hot water tank) comes from bottom of the stove.

Hi are you saying your domestic hot water from the taps is not getting very hot but used to from the boiler stove? What was the previous temp setting before you adjusted the pipe stat to 50?

The pipe thermostat may be faulty? This makes more sense as it would explain the rads heating longer even with the fire slumbering. It would seem the pipe thermostat is switching on the pump and circulating cooler water than the temperature setting of the pipe stat.
Ie the pipe stat thinks it's the required temp setting but it actually faulty and not activating at the correct pre set temperature, but at a lower temp setting.

Or;

Depending on the plumbing design you may have a manual bleed valve on the pipe to the top coil connection and air in the pipe.

Another thing is on the bottom outlet coil from the cylinder is there a valve on here?

A picture of your cylinder pipework would be great:)

Your pipes from stove to cylinder should have one pipe from top of stove to top coil connection and one from bottom of stove to bottom coil on cylinder. I'm sure this is the case:)

I will be interested if the pipe stat is faulty:)

I think I had it at 55 but it does seem likely the thermostat is faulty as it only started to do this problem after I adjusted it to try heat the rads more. Cant take any pics as no phone and no camera but will this coming week when I get phone.

Your right about the pipes from stove top and bottom. The only valve near the cylinder is past where the bottom stove pipe goes into cyliner. In saying that the bottom pipe is actually the same temp the whole way from stove to cylinder and past it. Maybe some sort of issue with the stove and not thermostat cause pipe is same luke warm temp from stove?

We will wait for the pics:D The pipe going back too the stove from cylinder lower coil connection should be cooler than the pipe going to the top cylinder coil, this top one should get very hot!!

It is, well not very hot but hot . I post pics asap anyway and hopefully you can help me out you really are a stove fan .

Finally got my pictures today. Quality isn't great as used crap camera phone and had to hold a light bulb to get the light for pictures. Have a look anyway see if you can figure it out. Its still happening anyway the water goes luke warm and rads are only heating up hotish but not boiling. Buring wood and briquettes still. They used to tall get hot burning same stuff but when I started to adjust thero it all seems to have gone wrong. . The pic called "pump" is on the bottom pipe coming from the stove. The thermo is on the pipe coming from top of stove in pic "stove setting"

Hi:) I have had a look at the pics but I really can't see anything obvious. Best to get a plumber in to visit.

The pipe thermostat sounds as if it's working as it's activating the pump to heat up the rads. Is there any air vents on the pipework or does the pipework just goes to the small tank above? It looks like the pipes continue above where it tees off to the cylinder coils.

Good luck. Stove Fan:)

Gareth2011

No air vents on the pipes that im aware of. The pipe with the thermostat does go into the top part of cyliner but that pipe also continues upwards im assuming it goes to the small tank in attic not sure tbh. Its not a major problem but might see about a plumber anyway cause its the only way to heat the water. The oil doesn't heat the water . Thanks for the advice anyway

turn up the thermostat to 60-65 degrees ans see if it gets any hotter. it should beacause the water will have to reach 60 or 65,whichever setting you leave it at and then the pump will cut in meaning before pump cuts in the water will be 60-65 degree circulating through the cylinder and then that water will be let off to the rads once the pump cuts in. i have mine at 70 but my stat is at the back of the stove which is 3mtrs away from cylinder. so at the thank where the top pipe enters the cylinder the temp here is 60. im loosing 10degree give or take at this distance so i have to have it at 70

Gareth2011

I did turn up the stat alright, have it on 60 or 65 I think now. It heats the rads but more alright but the water is a tiny bit warmer. But my stat is right beside the cylinder so don't thnk im losing any hot water because of distance. I think its somjething to actually do with the cylinder itself or some sort of heating element somewhere cause the rads are ok. They used to heat up when stove blazed and then pretty much go cold when it died down and water would be hot. Now the oppisite, now the rads stay warmer for longer but water is only luke warm. I don't mind it so much would just be nice to have hot water for dishes etc.

Are u sure the pump is not constantly running.

Hi guys,

We recently moved into a house which had a stove installed in the kitchen area which also has a sunroom attached. When we have the stove lighting it just about warms some of the rads but only to the point of taking the cold off them and they are not giving out any heat as such. We also find that we have to constantly top up the stove and can see it being quite expensive to run. I think the make of the stove is a waterford stanley erin and has a thermostat that goes from 0 to 4 at the side. The stat in the hotpress is set at 60deg so I think thats right. The pump seems to be coming on and off when the temp reaches 60deg. i have bled all the rads but still on the rad nearest the pump/cylinder is getting anyways hot. Does this mean my pump needs to be replaced or maybe I need to get a bigger pump? Any ideas? Did you get sorted Gareth2011??
