Now go and propose you are installing a HUGE electric boiler and the voltage DROP will exceed permissible limits and you demand they upgrade their infrastructure. Throw in a non inverter driven heat pump with a huge start up current for good measure. I would be interested of you could get an electrician to measure the loop impedance at the supply point. Or even if you could do a quick and dirty method (I will tell you how if you have an ac volt meter)

That looks suspiciously like it. @newhome wins the virtual hug. But at 91.76 € I may need to find it a bit cheaper........

I used to repair and sell tv's and someone asked me to deliver. Turned out to be a crappy basement flat with no parking so had to chance double yellows and when I struggled to get the telly down there, I found there was no aerial. No sale that day and never ever again delivered.

Well I always have fun and games with a terrestrial signal here. We are in a bit of a valley, over the brow of a hill from the local transmitter. At the previous house as a temporary measure I put the aerial on a short pole on a shed on the highest point of the plot. When the house was complete I moved it to a pole on the gable end. Same aerial, but higher up with a clear view in the direction of the transmitter. I tried for about 2 hours to get a decent signal and failed, so I put it back on the shed and it remains there now. At the new house I put a short pole on mt scaffold storage rack next to the static caravan. The signal from that is not brilliant. I wanted a tv in my office in the house. I was not ready to sort out a proper location for an external aerial so I tried one I had. It was a well built monster of a band A aerial. I gave the elements all a bit of a haircut to move it more towards being band B and put it in the loft of the new house. It works reasonably well though get some break up occasionally when it rains. Satellite is more reliable and is what we use most of the time.

Anyone travelling from the Borders to the Highlands with a roof rack? they can bring it up to me.

Unless it is REALLY rusty, put it on freecycle and let someone collect it and make use of it.

It ties all the joist ends together (I know it as a ring beam)

You need to look up how far you are from the nearest transmitter and what the signal strength is like to determine the size of aerial needed. A lot of the "posh" looking ones have a reputation for being rubbish, particularly not very strong, but that is not an issue for an indoor aerial. THIS guy talks a lot of sense http://aerialsandtv.com/loftaerials.html

Yes indeed it is. I have seen it so many times using this sort of plastic bottle thing as the feed & expansion for a brine loop, mostly for GSHP's, I thought this is the way the professionals do it, so I will buy one and do the same. I never dreamed it would be so hard to identify and buy one. NEXT time I see one I will ask the installer.

Ouch, £5K for scaf hire. You could have bought your own Kwikstage for that and then not been pressured for time.

No way too late for that, that would have required thought when the foundations were going in.

Back to my search for this header tank / bottle thing. I have found a couple of pictures of the thing I am looking for: Top right filled with a blue liquid: Top left filled with a pink liquid:

I need one of those. The plasterer hasn't showed up this morning and is not answering his phone. God I hate relying on others.

Top Tip. If you are thinking of redeveloping, get all the tree felling,. pruning, alterations done BEFORE the planning application and the TPO's get slapped on.

DIY coffin made of old pallets. My final project?

No shower tonight then......

I haven't got that long to wait

Ah true, there will be 3 cast iron pumps in total. But isn't that what the inhibitor is for anyway, to stop them rusting........

At the moment no. It's not the self building that is the issue, it's the sale of the old house. With the depressed demand and consequent depressed prices, selling a house is not something I wish to repeat in the near future in any shape or form. In fact looking back, I have (with one lucky exception) always had trouble selling houses. So at the moment my thinking is I will leave this one on a box.

As I say, mine is the "compact" version with almost no water plumbing in the ASHP. I have to insert a pump, flow meter, auto vent valve, and magnetic filter in the connecting pipe work. Now here is another thing. The manual tells me the warranty will be void if I do not have a magnetic filter. Now correct me if I am wrong, the magnetic filter is to remove ferrous particles from the circulating water. I could understand that if I was using steel radiators or there was a steel or cast iron boiler invlolved. BUT I am using copper pipe, Pex Al Pex UFH pipe, brass manifolds and valves, a stainless steel coil in the HW tank, and I believe the PHE in the heat pump is stainless steel. Pray tell me just where these ferrous particles are going to come from. Another unnecessary expense?

You are not selling it to me. So far I would need an expansion vessel, a non return valve, and over pressure blow off valve some isolating valves, a fill loop and a gizmo to pump the antifreeze in. Vs a £20 header tank and a tank connector. For no appreciable benefit, more work to install and more to go wrong. If only I can find this bottle type header, otherwise a standard 4 gallon header is starting to look attractive.

So not long back one arm of government said we need to build more houses and we will relax the rules etc etc. Now we have this, effectively saying more national parks = much harder to get planning to build the more houses we need. There is nothing like joined up thinking in government, and THIS is certainly not joined up.

Don't tempt me, I have seen plenty of those when searching for the real thing. They tend to be pressurised which is not what I want but a small hole drilled in the cap will sort that.

Okay, I have never done a pressurised primary (yes I am a bit of a dinosaur) So tell me just HOW to I get the antifreeze in? With presurised you fill from a fill loop off the mains water, but that won't get the antifreeze in? With a header tank I just load the header with antifreeze and fill it from that, simple. But it still IRKS me that I have seen the item I want (this plastic header bottle thing) in use many many times but I just can't find one anywhere to buy because I don't know what it is called. MY ASHP is the "compact" version, which basically means it has no water plumbing inside it. It is literally the 2 ports of the PHE protrude through holes in the back and that is the only water connections to it, so no not really any chance to get extra plumbing stuff inside it.

I like the simplicity of a manual fed gravity feed & expansion. If I go pressurised then that's another over pressure / over temp valve and another D2 pipe to get out of the building and discharge somewhere.
