He turned up on Thursday and Friday with an electrician.
I asked him to do the following :
1 - put the insulation all the way through the lead slate to the manifold.
2 - put heat proof silicon around the lead slate (to fill in the gap where the pipework comes through)
3 - move the cable to the other side (so it wasn't exposed on the roof).
4 - cut the slack pipework so the run is a little shorter and tidier.
He has just taken out the old silicon and put new heat proof silicon in (orange looking?) but hasn't passed the insulation through the lead slate nor moved the cable.
He has just unbent the pipework inside the roof and made a right angle out of it. I asked why he didn't cut it to the right length and he said that that was the length the pipe came in at and in order to cut it he'd have to hire a cutter and jointer
tool... (ie just plain lazy in my book).
So he's done the bare minimum to get the roof area work done.
Can anyone tell me why you pass the insulation through the lead slate ? Will the heat proof silicon be ok or is there a known issue with not passing the insulation through the lead slate ? ie should I insist that he does this?
Down by the pump station...
I have checked the readout on the digital display and it's reading 29C. Is this about right?
At the moment I have a 300 litre heat store with only the solar coil working (?! I hope - the plumber hasn't phoned me but it does look like he's left a bill/invoice).
I'm waiting for my electrician to connect the heating element (18kw) side of things.
The pipes at the top of the pump station feel hot.
Is the digital read out the temperature of the panel or the temperature of the tank?
He's put the white expansion vessel sticking out right in the middle of the shed - I asked him to move it to the side so I can use more space in the shed. Are there any rules to the placing of this expansion vessel? Does it need to be lower than the pump station? Should the pipe run to it be kept to a minimum?
The rest of the pump station pipework is a bit of a mess if you ask me - in terms of layout.
I would have pushed it further to the left and had the pipework a bit neater but then again it's not me doing the work - a professional is
Well - any advice?
