Stove

Hi all,

We recently put in a stanley stove which has proved to be rather disappointing. It's one with a back boiler but doesn't throw out much heat or heat the water very well. It seems to be struggling..the area it needs to cover is quite large but gave the measurements to the shop we bought it from and would expect they'd guide you in the eight direction. Any suggestions of a decent stove/ range to heat a large area would be much appreciated.

Not my area of expertise so pure guess but is there any chance you're not getting enough draw off the chimney so the fire isn't getting hot enough? Does it get really dirty inside after a couple of uses?

What sizing in kWh did they recommend you install?

Always go bigger than you need, they got the measurements and gave you what technically should do but what should do and will do are 2 very different things. It could be the stove is just too small for your needs. Your plumber should know this anyway unless the shop sent a plumber to fit for you

Made in China.

You want a scandinavian brand, made of cast iron… they are not cheap.

I have a Stanley Erin boiler stove maybe 17 years now and it works fine

You need to use the correct fuel, a quality stove ovoid, don’t skimp on the fuel, it needs plenty to drive the boiler.

What model did you buy.

Are you using wood in it…is it wet?

Did you install a chimney liner?

No turf which is bone dry and coal

Yes the liner was put in same time as the stove

I have a stove with a back boiler. You need a big fire to heat water, radiators and space all at once. You could try lighting the fire with a half bag (about 10kg/a coal bucket) of smokeless ovoids in the fire box at the start as I do (for many years now).

The stove will take time, maybe 2 to 3 hours, before it really starts throwing out the heat as the boiler will be cold to begin with and will absorb a lot of the heat.

I find that running two rads along with the hot water tank works well with a medium fire. You could try this and add one more rad at a time if the stove can heat them hot enough.

To run 6 or more radiators along with hot water and space heating should be possible but would probably require a large fire that would make the room the stove is in very uncomfortable.

If I light the fire after 3or 4 pm, I don’t have to refuel again and it lasts for the evening.

Do you mean that we should switch off some of the radiators to boost the heat in the stoveand to heat the water a bit better.

topofthewind

Ya, maybe turn off any radiators that are in the same room as the stove and any that are in the next room. You could open the door to adjacent rooms after the stove gets heated up.

Sounds like you are lighting a small to medium sized fire and it’s not enough to do all that you are asking of it.

Ok thank you so much for your reply.much appreciated. Will definitely try that

A back boiler is a disaster for fuel efficacy and emissions of a stove. They're even banded in some country's because they don't emit a clean burn.

a college once described a back boiler as a water cooled stove.

Have a Stanley Reginald 15kw boiler stove which heats 11 rads. It's hungry for fuel though and takes at least 3 hours to get rads hot. Would usually light stove @ 5pm in the evening and keep it burning until 10pm at night by which time the all the rooms would be nicely warm.

The rough-sizing rule-of-thumb for radiators is like this:

1 kW for small radiators.
1.5 kW for an average-sized radiator.
2 kW for large radiators.

So if your stove is rated at 6kW at the back-boiler and outputting water around 65/70c then, then you can do the maths to roughly work out how many rads it can heat (at full tilt!).

Hope it helps.

Yes that helps.thank you
