No pressure on the heating

In an unrelated problem, it looks like we'll have enough fuel to get through the next few days - not because we've got more fuel, but because limescale in the tank has reached such critical proportions that it's blocked something - the hot water pressure is now rather low.

There is plenty of hot water it seems but it's just not moving very fast. The morning shower is now a little bracing since the mixer tap evidently hasn't noticed that it shouldn't be dumping the usual quantity of cold water into the mix. The bath still works, though it takes 30 minutes to fill.

We could get everything serviced and all the pipes flushed, but since we're planning to rip it out all in the next week or so, we've decided to live with it...
