Rikkitic:

It is dangerous to make assumptions based only on your own experience. Our old farmhouse is fused (old-fashioned wire fuses) at 15 amps for powerpoint circuits. It is never a good idea to run a total load close to the fused maximum, especially in an old place like this. I certainly would not want to try maxing it out.

why? a 15amp fuse should be put in to protect the devices and wiring from failing before they fail.

if they would fail at 15amps then you need to install a smaller fuse. and that's half the problem with fuse wire is you can put what ever you like in there with out to much hassle.

The problem with fuse wire is some unknown idiot who lived in the house years ago during a transition period thought he would be clever and he replaced the fuse feeding the hot water cylinder with steel wire. He probably did this because the cylinder was regularly blowing fuses. This was because the extremely hard water in our area was calcifying the heating element, causing it to draw too much current. We never knew about the fuse because we knew about the calcification and regularly replaced the element as a matter of maintenance. Once we waited too long and started hearing funny noises. I checked the hot water cupboard and realised something was wrong. I tried to switch it off at the cupboard but the switch was frozen. I went to the main board and that switch was burned through. I cut the main power and immediately wondered why the fuse hadn't blown, which was how I discovered the steel wire replacement, which must have been there for years. This very old house is entirely made of very old wood, which burns like an impregnated torch. I know that because we replaced some ancient wall planks and tossed the remnants in the fire.

No, the wiring should not fail at 15 amps, which is why it is fused at 15 amps. I see that as a margin for temporary needs or brief power surges. I don't want to have to replace the fuse every time the refrigerator or washing machine starts up. But I still would not want to run a constant 15 amp load on a single power point. You should always leave some margin for the unexpected.

I'm digressing slightly, but when I moved into my previous place a number of years ago I discovered that one of the previous tenants had replaced one of the fuse wires with a paperclip. Also, the pressure relief valve in the hot water cylinder was faulty and they apparently had failed to notice their astronomically high power bills.

I am trying to figure out whether the washer/drier combo machines do condenser drying or whether they need venting, and I am having real difficulty with this.

Looking at this machine for example, none of the marketing material or user guide make any reference to emptying the water tank at the end of drying, nor do they make any reference to venting. Is that because these washer/drier combos are using some other method of extracting the moisture? Is that why their performance is inferior?

Being a combo machine, it seems likely that it will pump it's own condensate to the waste. The same as when it's washing.

I think it is safe to assume that any dryer that doesn't vent outside is not going to work very well (compared to those that do) and will greatly increase humidity indoors during the drying cycle. The moisture has to go somewhere.

Condensing and heat pump dryers both condense the water from the clothes for disposal from a tank (or a plumbed drain line)

Work fine, but cost more than a vented dryer. I think some condensing dryers use water to cool the condenser surface so are wasteful of the resource.

Ahhh, of course! It hadn't occurred to me that a combo machine has a drain pipe, which a regular drier wouldn't usually have.
