New washing mahine Bosch WAN28209FR

The Haier hw60-14829 drum bearings failed about 2 months ago. It was nearly 7 years old. I've heard some bad ones, but this approached a jet engine. Couldn't be in a room with it. I would have replaced them, having replaced the brushes in the last year. About 3 hours work. However, it's not particularly well made and has no out-of-balance detection. This means it slams around the kitchen units and we're not always in the house to sort it. There is also the mystery leak. Never found it despite a lot of investigation.

After a lot of looking around 6kg machines it transpires that only no-name or non-EU made brands are 6kg and nearly all of those are 1200 spin. The Haier is 1400 and that makes a difference in winter drying outside.

Finally plumped for the Bosch WAN28209FR which is 9kg & 65 litre, made in Poland. 9.1 on repair index and 380€ It's massive by comparison going from about 450 deep to exactly 600mm. This meant recessing some worktop brackets and moving the power and water. Drainage was fine. The only other problem was the control knob which they omit from their side elevation. The door is shown and I'd planned to remove that (easy - 2 screws). I ended up hacking the door frame. Thanks Bosch. Let's hope you do know how to draw and, well, follow the drawing to build your products.

It really is quiet, and the door opens almost flat. It leaked on the floor below the detergent drawer on the recommended drum clean, and it looks like either it over-foamed or it's condensation coming up the filler pipe from the drum. Other candidates are too high water pressure, but ours is pegged at 3 bar. Apparently quite normal. A run at 40C/1 hour wash later on was dry.

CO emissions

 Using on-line calculators

1 flight from Tarbes to London 226kg

1 person drives 1000km in a diesel car 5l/100km 234kg

In a year we use 2MWh and buy 1MWh.

To buy 1MWh in France, typical emission is 45g/kWh or 45t (45000kg) 

Put another way, I can take 200 flights (45000/226) with electricity that we generate/save

The return journey to the supermarket we use is 26km, which is 6kg of CO. After 38 weeks of just food shopping our carbon emission is the same as a flight to London.

Our ISP reckons we use 3.8kg of CO per month = 45kg/year, which is about 8 shopping trips.

cement accounts for 8% of global emissions. The IET 9/24
