We have finally had a log stove installed in the hall. Ever since we moved in, we have had the fireplace boarded up and the stainless steel flue tucked up out of the way.
Since we have been delighted with the Firebelly stove that we installed in the snug, we have decided to install another Firebelly stove. This time it is the slightly larger FB2 model. This outputs about 12Kw, so it should be more than enough to heat the hall, stairway and landing. They come in a variety of colours – this one is sky blue.
We have had absolutely no trouble with our existing FB1 stove – it is a dream to use – easy to control and clean. I am sure the FB2 will be just as good.
Anyone who has owned a log stove will be aware of the problems of the stove glass sooting up. Some stoves seem worse than others, but it is something that all stoves do over a period of time.
There appears to be two main causes:
- Poor fuel: This usually means logs/wood that is still damp. The drier the wood the better. Logs should really be air dried for up to a year. This will get their water content down to 20-25%. If you want to be extra sure, you can use kiln dried logs. These are frequently down to about 10-15%;
- Not enough air: This leads to poor combustion and smoke. This will eventually blacken the glass.
The solution seems to be:
- Use the correct wood fuel;
- Ensure that the fire has enough air. There are usually two vents – one allowing air in from the bottom and one allowing air from the top. Logs burn best with air from on top. Start the fire with all the vents open. Once the fire has started going, shut the bottom air off. For example with our Firebelly stove, we leave the top vent open 3/4 of a turn. This never changes. We open up the bottom vent fully when starting the fire, we let the fire burn through (this warms the chimney/flue and establishes a good draft), then we add more wood and half close the bottom vent. Once the fire is fully established, we close the bottom vent completely. The top vent is always left in the same position;
- Make sure the fire is burning hot enough. We have a Stovax flue thermometer that shows the optimum temperature for the flue. This ensures that the exhaust products from the fire reach the right temperature to be burnt off. They cost about £10 and are a good investment.
All of the above works really well with our Firebelly FB1. We seem to be able to burn just about anything on it (we never put treated or painted wood on the fire) and it never soots up. The Spartherm unit (Arte 3RL) is a different story. Despite only putting kiln dried wood onto the fire, it always seems to soot up. The Spartherm glass goes black all over. While some sooting up is inevitable, this seems to happen within 1-2 hours. There is only one control on the front. This controls the air flow from underneath. There seems to be little control of the flow from above. There is also no opportunity to view the temperature, so it is difficult to tell whether it is hot enough.
We wrote to the manufacturer. Their response was to send us the manual that we already had (the same one that was supplied with the unit).
We have found the easiest way to clean it is using Stovax clear glass cleaner, but it soots up so quickly, we really avoid using it too much. It is shame since it is a nice looking unit. But we have better things to do that clean the glass everyday. The Firebelly unit is a completely different story. We have used it continually and have only had to resort to cleaning it once a month. And that is often just to take the odd black soot mark off the glass. It takes all of 5 minutes.
The new fireplace (based on a Spartherm Arte 3RL 100H fire insert) was plastered last week. The plaster has dried out over the weekend and we expect to get the lounge decorated this week (with a bit of luck).
We have had the fire on today as the ground source heat pump still isn’t working! Nibe (the manufacturer of the heat pump) are due out on Wednesday, but in the meantime we have no heating or hot water.
Although the house is fine, we did lose one of the bigger trees in the orchard yesterday afternoon. I suspect we were actually around when it fell down, but we didn’t hear it.
We waited until the wind died down before attempting to clear the debris. Our chainsaw managed to cut through all but the largest branches – I suspect that we will have to get our friendly tree surgeon to deal with these. The smaller branches will go on a bonfire. The larger ones have been cut up into firewood. It will be around 12 months before these are dry enough to burn.
We have pushed ahead with the fire place in the lounge and, by the end of the day, we are ready to fit the plasterboards on the metal framework. Even without the plasterboards on, the fireplace is usable. I can’t wait to see it in action. We even had a fresh delivery of kiln dried logs yesterday!
We have made some more progress with the fireplace today. With the wet weather, we have been looking for indoor activities and finishing off the fireplace was one of our top priorities.
All of the pieces of ashlar that form the fireplace are now in position. We need to build the chimney breast around the fireplace. This will be done using the metal framework that we have used elsehwere during dri-lining. We will then board this with fireboard – a sort of plasterboard that has increased heat resistance.
At the moment, this still ins’t looking like the finished product.
The missing part for the Spartherm unit turned up yesterday and the installation was finished today.
The good news is that the unit looks great. The bad news is that the flue on the outside looks like something that belongs on a fast food takeaway!
This is hugely disappointing. After all the time and effort that went in to ensure the view of the building from the sunken garden looked great, we now have a large stainless steel flue protruding over the ridge line of the building. This is not what we had intended.
Apparently, the flue needs to be 3m higher than the top of the fire box. Otherwise, we would have lowered it below the ridge line. In terms of colour, we could have got a powder coated flue (we only needed the top that sticks out of the roof), but no one told me this when we were sorting this out. And it is big, the flue is 7 inches across with a large stainless steel “hat” on the top.
We will be looking into alternatives here as this doesn’t look great. Ho hum!
Although we are still missing a crucial part for the Spartherm unit, we have taken the time to get the Firebelly stove that we bought a few months ago installed. It is a FB1 stove in pewter with a matching stove pipe. Other colours are available.
These stoves are made in Elland (just outside Halifax), so are very local to us. You will find more information here.
The stove is exceptionally well made and we are really pleased with it. The glass front provides a great view onto the logs inside. It burns very cleanly and the glass stays clean while in use, even when the air supply is turned down to slow the burn rate. It is easy to light and the combustion seems super efficient leaving the minimum of ash.
The firebox for the lounge arrived yesterday. We have a slight problem in that the baffle (butterfly) for the flue seems to be missing. However, we should be able to get the unit into position and build the stone fireplace around it. There will be some “fine tuning” required, but nothing that the builder can’t deal with. The design of the fireplace is covered here. However, re-looking at the pictures, we have significantly changed the design – we are now using a firebox with 3 sides of glass rather than 2. We have also gone for a design that is a little more symmetrical.
We are going to have to wait for the missing flue part before using it, however, we can get on with the job of installing it into the fireplace.
The installers are also going to install the Firebelly stove that we bought a few months ago. So although the Spartherm unit might not be operational this weekend, the Firebelly should be!
We are trying to sort out the arrangement of the hearth in the lounge. We need to settle on an arrangement fairly quickly as the roof starts to go on next and we need to know where the flue is going to go.
The challenge here is that this end wall is very tall.
We are considering internal windows from the lounge into the master bedroom – high up so privacy isn’t an issue, but it does connect the master bedroom with the other spaces.
We are also looking at corner log stoves (although not shown in these pictures).
While this arrangement isn’t exactly right yet, we are starting to get there (I think!).
