yup.

Surely it's the mains into the CW tank that's the problem? Stopcock not fully open/ crap in the float valve?

Quite fancy a single post lift myself. The portable low/mid-rise variety are great for tyres and brakes but I reckon I'd prefer to be standing for the real underneath stuff. With the pallet-truck singlepost jobbies you can shunt them out of the way when not in use or even (door height allowing) wheel them outside too.

generally there's a recess round the edge to set 8x3s into.

try a cable tie or two instead of the jubilee clips.

so someone else does the dirty work then they sign it off?

Paraffin wax changes state at a nice low temp and is used by the bucketful hot and liquid in Histo labs. Nothing to be afraid of...

I like the paraffin wax option.

"What's the problem? I can’t find my address on Postcode Finder Tell us more: Address attached to site in 2010 or thereabouts. Currently building new residence."

On a whim I filled in the online form on Monday and have just received an email confirming our address would be live on the database within two days. Nice!

IR is better for big open spaces- heats you, not the air.

Lovely. Many congratulations. Gives me something more to aspire to...

I might've asked this before but what *is* the "breakdown" temp, where the goo starts to cook? Surely a hard limit on the immersion element temperature would be all that is required to safeguard it. We see similar strategies in Autoclaves for redundant boil dry and overheat protection; some have a capillary stat clamped onto the element, others ( in an external boiler) have a PT100 in contact with the element, going to a spare way on the microcontroller.

What about the "high temp" units http://www.earthsaveproducts.com/product/high-temp-12kw-air-source-heat-pump/ I believe some are just r134a filled, but there are others that are dual compressor/ stage?

the rubber end bit normally has a bit of a cuff on the inside. Sure your barbed fitting won't push on down into this?

Since when was 21c cold?

Keylite also.

I dont't know about that. Pulling a hose up the stairs and pouring to datums seems pretty easy.

Pozis are 254x 75/90 at 400ctrs with a max span of 5040. I'll ask, but I doubt there's a standard detail for it as screed thickness will vary between brands and no doubt ther's a number of ways to build and hang a staircase anyway?

Must admit I hadn't, Dave. Why do you think matching it to the stair would be so much easier? There's still a structural floor and a finished floor either way.

@ProDave because of the extra solidity it brings to the house underfoot and in terms of noise transmission and also because we want wet UFH in some rooms. It does give a great feel. Posijoists and ceiling heights have been calculated for it... @the_r_sole the supplier prefers at least 25mm over pipes so 45-50mm. It certainly seems to be a thing over here as some of our TF quotes included the load calculation without our requesting it.

So we've currently got posijoists and Caberdek and I'd like to have the upstairs prepped to pour the screed sooner rather than later. What trimming is normally done to the landing area prior to screed- a 3"x2" on flat or somesuch? Obviously there needs something to contain the wet mix, but subsequently the staircase and balustrade need structure to attach to and I'm guessing that treading on the edge of the screed and/or drilling into it's perimeter are bad juju.

soft start and variable speed.

@JSHarris what is the fan doing in that 0-4c zone- Is it at low speed? Is there a chance more airflow might reduce icing?

There's one chap local to us who has had scaff up for approaching two years now. It was supplied by the firm that did ours and he does the odd job for them occasionally to "settle the score". Apparently.
