I'd say that the water from your tumble dryer is probably safe to put on plants.
But Duff please note the use of that weasely word 'probably'.

To cut out the guesswork you need to be really sure of what type of waste water you have ended up with. And to be sure, you first need to ascertain the pH value of the water in your tumble dryer...that's because plants are notoriously very picky about the alkalinity or the acidity of the water they sit it. The level of alkalinity or acidity of the waste water will either make your plants thrive - but get it wrong and it will kill them stone dead.

Fortunately there are plenty of ways to test the pH value of water and you could just google the words...Ways to test the ph level of water . I won't babble on, it is best if you read what WikiHow has to say. You can simply double click on https://www.wikihow.com/Measure-the-pH-of-Water and get all the info you need.

To cut a long story sideways, WikiHow says that the best (and simplest) way to test for pH is to use a gizmo called a pH meter. I heartily agree with WikiHow - and I can give you some more really good news...you can pick up pH meters from Amazon for as little as £3.99.

To recap: It is absolutely essential that you test the alkalinity or acidity of your waste water before you splurge it all over your garden - and a cheap pH meter is the best way to be sure before you go merrily asplurging. Get the pH level right and you'll be rewarded with a lovely garden - but get it wrong and your garden will soon be a barren necropolis of plants.

Then, depending on the measured results, you can either google Plants that like acid water or Plants that like alkaline water and you learn which of your plants to drench with tumble dryer water or not.

Oh fraptious joy! The mystery has been solved at last!!  After 3 years of lying ignored and unanswered, I accidentally found the answer to this question - on Wiki.

Wiki tells me that there is actually a very good reason why a cape on a poor little Antarctic island was lumbered with the godawful name of 'Cape Circumcision'.

First, you have to cast your mind back to 1739, because that's when it all started.

Back then, a little known but intrepid French explorer (called Jean-Baptiste Bouvet de Lozier) was the first man ever to clap eyes on Cape C, way back on 1st January 1739.

And, Wiki also tells me that, according to religious tradition, the First of January just happens to be The Feast of the Circumcision in Jewish tradition 8 days after the birth of the infant baby Jesus who, as we all know, was famously Jewish. Hence the cape's rather gruesome name.

Personally I still prefer the idea of the cape being named to commemorate the mass enforced circumcision of the expedition's long-suffering crew members in a sub-zero remote Antarctic snow drift would have made for a far more interesting and eye-watering reason for its naming.

But it's named after nothing more creative than the day when the Cape was first discovered. Now, isn't that a really gripping fact worth waiting more than 3 years to find out about? Nope. I thought not. OK. You can all go back to sleep now.

Nice to see that you did eventually get reimbursed.

I eventually got a refund of the courier charge (but not the products) - I had organised the transportation, so I put it through my credit card's protection system, and they refunded the money fairly promptly.

Okay, so we've moved house (again) and I now have a new office being built - but have the same issue.  I'm in the office most of the day  when the house is empty, so there's no point in putting central heating into the office

What would be my best option for heating economically?  To add to the mix below, IR heaters seem a cost-effective alternative.  Apparently, these heat the items in the room rather than radiating heat, and I have plenty of wall space.  Should I be considering IR heating?

The quick look I had suggests that the costs would be the same as a electric bar fire, so I don't think it would save anything.
Another possibility would be a calor gas cabinet heater, the downside would be that these release a fair bit of water vapour into the air so condensation could be a problem as well as the space needed around it.
