Drainage pipe in the UK is almost exclusively plastic and has been for as long as I can remember, older installations have cast iron or glazed clay and sometimes an asbestos like material.

Copper or stainless is occasionally used for decorative purposes under basins but I've never seen it in 3 or 4".

I will try feeding the supply to the hot water through it to see if it's any use at all but right now I'm guessing it will be scrapped when the extension happens.

Actually it is best as a cold supply to the shower. Then the hot can be balanced down. Or...you could have it feed the cylinder, either/or.

Yes, our drains are all plastic now but commercial or multi res code still demands copper or cast iron so the piping is available. Fire code stuff.

Looks like the heating season is about to begin, little earlier than I'd hoped.

Mostly due to us being mid loft conversion and having stairwell open to an uninsulated loft.
Outside temp dropped below 3C last night so our hallway was a chilly 13C when I got up this morning.
I'll get round to posting details of the loft conversion over the next few weeks but have decided to share details of my energy monitoring setup first.

The system I'm using is Home | OpenEnergyMonitor
Had it running in various forms since March this year and have been adding to it slowly since then.

Still need to make some more public dashboards but here is the heat pump screen, data is updated at 60s intervals.

Gave in and turned on the heating as it will take a day or 3 for the heat to make it's way through the floor slab.

I completely understand the need to "warm up your brain" in the morning.

However water, as good as it is at heat transfer, is not perfect.

Here's a method I use in the morning to warm up my brain, and it is quite effective...



You'll be surprised at how quickly it works!

Best,

Just too much work.

I gave it away.

You're assessment of these little heat pump water heaters got me thinking about the tube in tube condenser being undersized.
So I tried turning the circulation pump up to full speed, consumption of the pump rose by around 20w, output of the heat pump rose by 400w when heating the floor and by 900w when heating the hot water tank.
This is a huge improvement with cop now nudging 3 at times although I have a feeling I may have issues with the evaporator icing due to the extra heat demand.

Great to know that even bad advice can be put to very good use.

Way to go!
