Water Heater

We've spent a lot of this weekend inside, getting the new hot water system installed. A few weeks ago we ran a new power cable and data cabling (shielded Cat 6 ethernet) from the utility room all the way to the boiler room. Now, we've removed the two blanking plugs from the accumulator tank (easier said than done: it took a 24" pipe wrench, and a lot of welly), replaced them with 3kW immersion elements, and connected up control gear to them. This is the clever bit: the control system measures the import/export power from the mains incomer (the connection to the national grid), and only puts as much power through the immersion elements as is spare. That means that the water heating is free, as we don't import any power from the national grid, if there's space in the tank to heat water.

Sounds easy, but it's taken an age to get everything connected up and working properly: however, it does look like it's working.

This afternoon we potted up about fifty various brassicas, which will go in the ground later in the summer. They've been in modules, but they're getting a bit sad in these, and it was time to pot them up properly.
