Yes, let's wait for Gaston. A quick calculation: either gain per SL: 2.5kwh gain per year: 2.5 * 2 * 52 = 260kwh / year number of Belgian households with an SL: 4.575.959 / 2 = 2.289.980 households source http: //economie.fgov .be / en / modules / publications / statistics / population / menages_prives_taille_menage_nombre_menages_collect.jsp ...

2) What additional embodied energy to manufacture the heat pump? Let's say 30 € and that 20% of the price represents gray energy (up to the customer) or 30 * 0.2 = 6 € of energy ... to be converted into kWh ... let's say, depending on the price of the kWh, between 80 and 120 kWh ... l So 120kwh / 2.5 (gain per SL) = 48SL so ...

Ah yes as much as that? Or around 5 million people, so 1 in 2 Belgians is equipped with SL? : shock: Yes, in fact 55% of the population is equipped with a sl with an average operating rate of 2X / week 2009 crioc study http://docs.google.com/viewer?a=v&q=cache : rub15xGvWcAJ: www ....

The fact that we know how to make them reliable does not necessarily mean that all are reliable:? Obviously Two questions that should be answered to start the calculation: 1) How many tumble dryers are there? (I do not have any). 2) What additional embodied energy to make the heat pump ...

PE can only be welded to the mirror or electric sleeve, see Geberit drainage system. http://www.geberit.be/web/appl/be/wcmsbef.nsf/pages/prod-evac-outi-1. But it does not hold the pressure: cry: If I had to do it, personally I would take a slightly larger piece of copper pipe, and insert it ...

Yes, that means that we know how to make them reliable, especially since in this case, as for the refrigerators, it is a "monobloc" system. This means that we can trust it and therefore take it into account, good news. So 0,5 euros savings per drying. If the additional cost is 250 euros, it is necessary ...

Thanks to Chatelot 16 and Gaston for these answers. Thanks also to Christophe for Do not you think that over 5 or 10 years, a household refrigerator compressor will have been running many more hours than the heat pump unit of a dryer from the same household ?? Which would mean that the heat pump system ...

Well, yes, but how does the condenser work? No idea: cry: In fact I bet it is more economical to use a dehumidifier in the room where you dry your laundry (if it really takes too long to dry) than to use a condenser dryer !! Except that I miss cruellem ...

Uh I thought that all condensing clothes dryers had a fridge group (so a heat pump!) Since to condense, you have to cool ... then the one with a heat pump simply has to recover the heat from the cold group in some way. 'another. Afterwards am not Doctor and dryer! Well ...

What "kills" synthetic materials in general is UV.
Sandwiched in the construction, they are protected from UV ==> no degradation problems over time
