Grade one…

A grade one copper cylinder is now sitting pretty in its little house. Mind you, after all the measuring, the tech drawing and the ” this is good sir, we don’t normally get a well drawn plan for a replacement” it still didn’t fit first time.
After draining down the system, the old twin coil tank was removed and inspected. The base of this one has been leaking for a while, a repair was carried out by yours truly but it’s gone in a different spot this time.

It could be repaired again but its a grade three tank that has thinner a copper wall and will no doubt fail again in a short while.
The first task was to carefully extract the special one kilowatt immersion heater, used as a dump load of the trace sw4548 inverter.

A cracking idea as when we have excess power from our wind and solar,ย  when the battery bank is full the inverter tell a relay to operate thus switching on the immersion. Hey presto, free hot water.
Fitting was a bit tricky as you can see, i don’t have the proper box spanner for the job.

It took the two of us to get this 1.5 meter beastie upstairs. While i grappled with this awkward monster, mrs republic tackled the cutting of the reeds, http://www.pfaf.org/user/Plant.aspx?LatinName=Juncus+inflexus or hard reed was made short work of by our flail.

The cupboard ready

It was time to manoeuvre this leviathan into place.

This is when trouble started, the old tank used bsp tank fittings and the new one had 28mm standard pipe fittings.
image

nowt would fit, so of to town again, this time for an adapter. Of course sods law, no such piggin thing exists. Once home it was plan b, modify the pipework.
image

These 28 mm obtuse bends had to be un-soldered, cleaned up and a longer length of pipe soldered back in.image

I dislike this idea as in my mind a re- soldered joint just doesn’t strike me as 100% sound.

After all the messing about today, the finish line seemed a long way off. Luckily, the tank is in, the fire is on and we have hot again.

Bring on Tuesday….
