got a bit of an awkward job to do. basement with under floor heating. one of these would be ideal. are they easy enough to operate???? dangerous???? thinking of hiring one out and sussing it out for a day then getting on with it. would be great if any of you guys had any info or experiences with these babys. normally knock up with a mixer or get ready mix but client is fussy about the heating pipes (ceramic) and im brainstorming. would cut down on a lot of hoofing! cheer lads.
