Mad idea for DHW retrofit based on Mixergy?
SteamyTea replied to JamesPa's topic in Air Source Heat Pumps (ASHP)
It is because, as you have shown, a lot more inputs and outputs. I always reduce the ∆T by 3K as that is where my house seems to sit above OAT when left empty. -
Try culling into it with a sharp knife. Whoops, did I type culling, meant to say cutting. Culling it what need to happen to idiots.
-
What I am finding, only 18.8°C as I type this (16:25 10/04/2023), but I can live with it. And I am saving what, £3 a week, the same as a coffee.
-
Can't think why not. Evan 25mm of PU or EXP would help. May need to drill some ventilation holes, or pull the plasterboard off and get more thickness. Get a multitool and you can trim it all easily.
-
Last one I did the unit cost about £20. I think when I did them in 2006, they were £16 each. Shop around.

Meant to say outer, no idea how I got my inniey and out confused.

Workshop build using shipping containers - Electrical Advice

Last time I was arrested I had a leg spasm, think it was caused by a coppers kneecap. All I remembered was saying 'ha, missed both my legs'. -

(expletive deleted)ing autocorrect. Truncheon -
Well first full week with the heating off, and as I guess, maybe a bit too soon. Mean house temp is now 17.8°C, down from 19.3°C the week before. External temp, 7.9°C, which is lower than the week before, which was 8.5°C Consumption is 43.4 kWh for the week, 80% at night. Week before was 67.2 kWh, with 85% at night. Here is the windrose and the consumption charts. The difference in the external temperatures is rounding errors and my rear garden sensor and the local WU weather station. Week before

Would that have been their notebooks, blood stained truncheon, camera memory cards and morals. -
Many years ago, I put in a secondary pane of glass into a window. It misted up in a few weeks. I then cracked the inner pane during bedroom antics (moving furniture but that is boring). The misting vanished in now time. I have often though that a small hole drilled into the inner pane may alleviate this problem. May get brave and try it out on a blown unit, but only after I have a replacement ready.

Computer Reaction Aided Production will be next.

I think that is the case. The first replacement I did was too small, but is still good. The rest, I made a bit bigger and they have failed. The glazing man only offered 1 year warranty on replacement panes if they were going into timber frames. When I do get around to replacing them, shall go a bit smaller, and have already put in weep holes. Shall also put in more silicone and accept I will need to scrape off the excess. That bit is easy now as I am not going to be renting the scaffolding. Cornish weather plays havoc with outdoor work timetables.

Or block off that bit of the eve vent.
-
My experience as well. Also, the north east facing painted windows 'weather' better than the south west facing ones. Less UV, rain, salt and windspeed.

Go on, we all love a good yarn. -

As this a steel, temporary/portable building, won't the mobile home wiring regs come into play. I would hope a electrician would know, but many may not have had to do one in the past. -
Are the tiles the easiest / most cost effective?
SteamyTea replied to JohnBishop's topic in Wall Tiles & Tiling
I got a sample of Tricoya and dumped it into a bucked of water, left it outside for 13 months. No change. So I guess it does depend on what MDF backing they are using. Some are designed to absorb a bit of moisture to close the T&G joint gap. I often wonder why these types of panels are not used instead of plasterboard and plastering, especially on factory built houses. -
Use space under the stairs
SteamyTea replied to JohnBishop's topic in General Self Build & DIY Discussion
I store my scaffold tower under the stairs. Made a shelf, then boxed with a removable panel. I am currently making some long draws for the bedroom, on the final one at last. Not that hard to make, once you have made a couple of decent angle plate, then just glue and screw. -
Good hoover for cleaning a building site
SteamyTea replied to JohnBishop's topic in General Self Build & DIY Discussion
If we remember back to the early pandemic days, when there was a lack of face masks, it was suggested that the best material to use was T-Shirt fabric. Should not be too hard to make up some washable bags. I think I will design a vacuum cleaner. Shall call it the Daniels, already got an endorsement from Donald Trump, he said 'Daniels sucks'. -
Which is probably why they have fogged My old ones where puttied in. Siliconed the new ones in, and they have still blown, except for a couple of them. I think I know why. Measure frame thickness (a), measure one side to the glass (b) measure other side to the glass (c) a - (b + c) = glass thickness

Mad idea for DHW retrofit based on Mixergy?
SteamyTea replied to JamesPa's topic in Air Source Heat Pumps (ASHP)
I have, after a long 12 hours driving, rather lost the plot in this thread. With current technology, I think that @markocosic us right. The main thing is to not let the enemy if the good be the better, I am still waiting for my sustainable electricity from Hinckley Point C. The one that I was told in 2005 would supply 8% of the UK's electric. I was told, in 2006, by David Elliot, that it would be over 20 years until it happened. So 3 more to go. -

May have been my autocorrect changing things. Basically, having a store of compressed gas is quite dangerous. To get large modulation the pressures will have to be quite high i.e. 200 MPA. Also how would a heat pump work as an instantaneous heater for only a few seconds, current combis don't cope brilliantly. -

I think it will come down to size of the outside unit. You have to shift a lot of air to get 45°C water out of the tap at 20 litres a minute.
