Pellet or Wood burning stove ?
 
Hi, we have a big (8m*5m) room and would like to put in it either a wood burning stove or a pellet heater. THere will be one radiator to provide some background heat but the main heating would be from the stove.

The wood burner obviously looks nicer and has an attractive ambiance, but how long in general do they actually stay hot ? If someone put that on in the evening and were staying in the room, would it heat the room until morning (assuming it has stone exterior for example to retain heat) ? The pellets are less attractive visually but they do have the advantage of long term constant heat.

Also, does anyone know cost different between the two on a running basis ?

Thanks
Mike

I can't help on the costs - despite having 1 house with a pellet boiler - but the tenants like it very hot so I can't give a good estimate of annual costs. Pellets are considered to be CO2 neutral as they are produced from waste material where the original process has counted for the CO2 production.

However, our main house is heated using oil, and the thermostat is set quite low. We supplement with a wood burning stove in the living room - so in the evening (around 7pm) I will light a fire. I will go through a total of 3 to 4 pieces of wood (hard fire burning wood) in an evening. When we go to bed we close off that room. It is still warm in the morning.

There are a few users on here who have houses heated by wood fired stoves - so they may provide more detailed information.

We had a stove in our previous house from Tonwerk. They are storage heater stoves and retain heat for hours and hours. In 6 years, we never once heated thr ground floor of our house by any other means than by this stove. It was expensive to buy but then running costs were minimum. The room was a large open plan ground floor (including living area, dining area kitchen and hall) but despite the size it was often too hot and we had to open windows.

This is the one we chose. It was 9 yrs ago so they could have introduced better models since. http://www.tonwerk-ag.com/en/Products

We have a HASE woodburner clad with 'pierre ollaire' or alpine stone. The stone cladding acts like a storage heater and keeps giving out heat for quite a long time after the fire has burnt out. Love it.

In both houses in which I've lived, I've installed wood burners - but as a secondary, back-up, in case main heating system fails or continued power outage.

In the first house, which was old and relatively small with low ceilings, we used it occasionally just for the 'look' of a wood burning stove, but every time, I had to open all the windows and only put on a couple of logs. We all ended up with red heads.
It was the smallest oven we could find, and had tiles on the side, which retained heat (as did the metal housing).

In my current house, which has double the floor space as the first and much higher ceilings, I bought a mid size oven from Bauhaus for under a grand, and similarly, it has been hardly used, because it puts out too much heat.
I think this one has internal heat bricks, which retain the heat and gradually release it after the fire has gone out - plus the metal housing, again.

I have experience of pellet ovens only through my work place, which uses one, and I noticed that at my daughter's school there was a fresh pellet delivery the other day - so they obviously have one, too.
I don't know if this implies that they are particularly effective when large areas need to be heated, despite pellet ovens being available for domestic use.

I'm sure you're aware and have taken it into account but you obviously need an outlet for smoke - usually a metal pipe which can installed independently, or contained within an existing chimney - I've done both.
An independent metal pipe will need to be enclosed in a heat proof and fire-resistant casing, if it runs exposed through upstairs rooms.

I would check out the planning/approvals required before going much further. The Fire police can be quite funny people to deal with. Personally I would go for solid wood, pellet fires always seem like vegan burgers, tasty but not the real deal!

We have an oil fuelled heating system with 2 wall radiators in a room with a lot of windows, and sized about 18 foot x 10 foot. (clearly an old house because it has none of the fabulous underfloor Swissy heating)


3 years ago we installed a wood burning stove - cast iron. And digressing a little - we had to endure the disgust of the Swiss installers because it was made in Italy, but SO much more attractive for our taste than the Tardis looking beasts that the Swiss prefer from the Nordics or Germany.


Anyways. We live 1000m above sea level and so have a LOT of snow in a usual winter, typically from November to April. And I originate from hotter climes anyways so I keep the fire running nearly every night of the year regardless of weather.


We use about 6 pieces of dried 33cm wood every night through the winter season. It burns to about 11pm and if we close off the room, it is still warm in the morning.


We buy 2 ster of brennholz (pallets of chimney wood) for I think CHF 180 each every year.


In fairness, this is the expensive bark stripped wood from the Landi - we've also tried cherry wood from the local farmers which was about CHF 100 per ster but didn't think it burnt for as long. Am sure so much depends on type of wood and how "cured" it is and different parts of Swissy have different pricing levels as well.


We can use the top of our stove to heat casseroles/plates/bolognaise sauce.


Our oil heating consumption has dropped by 18% annually since installing the wood stove. (married to a geek who measures everything)


We explored the pellet burner option as well. Definitely a more efficient method for heating and cost. But no where near as pretty to look at for our taste. (although I see that Italy now are starting to make retro looking pellet burners that are as "cabin woodsy" cute as our current wood burner)


No effect either way on smell. All approved wood stoves within Switzerland are so tightly sealed that the floating ash and smell excitement is.....non existent. Sometimes I sit with the wood burner door open, just to get a whiff but given we live in a wooden house, this is naughty of me!)


We actually use those pellets for our cat litter trays (eco friendly) - the biggest annoyance is that the bags inevitably incur at least one split from the shop to our house, so we wind up with pellets through the car to be cleaned up or worse, pellets spilling and sneaking underfoot - and they're not fun to unexpectedly tread on.

+1 for Tonwerk. A very old company with an impressive range of modern and nice looking storage heaters.

Same question but as the primary heating for 70 m2? No oil central heating, only other heat source is electric storage heaters. Would be aiming to install a burner to minimise annual electricity costs

As an aside, bearing in mind I tend to prefer the cast iron type over the nordic designs, I love this one from Tonwerk, but suspect we'd need 8kW, not just 5

You can have both!

There are now (at least) two firms that sell pellet stoves where you can burn wood as well. So you can light the pellets with your app on your smartphone, and then once the fire is going, you can throw on some wood. An exciting development and the best of both worlds:
http://www.rika.ch/de-CH/induo/
http://www.sht.at/deutsch/service/prospektdownload.html

According to one review, wood pellets are as expensive as oil per kWh (http://www.energie.ch/heizungsvergleich), but pellets are about 30% cheaper in Germany if that is a practical alternative.

Finally, you can connect some of these combi heaters to your Pufferspeicher, so the heat from the stove can be used to heat your boiler as well.

Wonderful technology!

Didnt expect this to get re-pushed but to let everyone know we ended up with the ComfortAir system from MCZ. this is a pellet stove but with piping around the house, in our case heating to large rooms and two hallways. so far happy with it though as its summer its just done a few test runs. winter will come up with the real costing though pellets are very cheap - 5 CHF for a 15KG bag.

I'll update in a few months when we've worked out how much its munching.

Installing our 2nd wood burner here in the coming weeks. Few years back we installed a 1960's Rayburn that runs off solid fuel and now we have Morso (Denmark) stove on the way. I've just cut and prepared 5 cubic M of wood although we typically use around 2-2.5 p/a.

Wood is cheap here in CH compared to many other things and other countries.

I've never used pellets as my chainsaw doesn't cut them:msngrin:

Re: Pellet or Wood burning stove ?
 
Out of interest, how accurate is the heating capacity in the specs for these things? i.e. if it says an 8 kW stove will provide heating for 243 m3 area, is that as an ancillary heating option or sole source? And is it assuming that area is one open area? If looking at a stove as the primary source of heating for the whole of a small flat, should one over-dimension?

An update from me: we opted for an 8kW pellet stove, manufactured by Jolly Mec (Italy), supplied by a company in Solothurn. It was only installed yesterday and we're going to have to fiddle around with the programming and settings to get them right, but first impressions are very favourable.

(And I have no idea why the photo is on its side or how to rotate it - sorry!)

Maybe the guys from Solothurn installed wrongly ?;)
