Lorna and Richard's Hot Water Cylinder

Lorna and Richard had a new central heating boiler fitted at the end of last week, and the job included replacing the hot water cylinder in their airing cupboard. Since I work with metals and like to keep a bit of copper sheet about the place, they were kind enough to donate their old tank to me, so last night I dragged it over the road into our back yard. It weighed an absolute ton!

Today I cut the top off with a hacksaw, and discovered it was 1/4 to 1/3 full of limescale! No wonder it was heavy! You don't really get the right impression from the photo, but that white stuff is over 30cm deep! Their new tank came with the usual sprayed-on insulation, so it's possible they'll see a reduction in their heating bills.

Now we're going to play in the wine cellar, moving stuff from the 'lay it down' section to the 'drink it up' section. Ah, the joys of living in an ex-pub!

That's pretty amazing. I reckon this would have saved them money because they were heating less water than if it were a bigger tank with less limescale though?? Thoughts?


Rob Clack said...

Ah, I hadn't thought of that. Tricky... And of course, with all that limescale lining the tank, it would have been better insulated, too... Hmm, thinks...

An ex-pub, eh? How very interesting.

House was built in about 1870, the walls being constructed from chalk rubble excavated from the 2-room cellar. Some time around the turn of the century it became a pub and stayed that way until WW2, after which it was gradually neglected. Restored in 1970 with extra-cheap wooden window frames, doors etc, but expensive, personally-imported Italian ceramic tiles on the hall floor.

Same person moved the staircase and concreted over the internal access to the cellar, so we had to have a trap-door installed. We've replaced all the windows and doors long since, of course.

And the end result is indeed, interesting!
