A pause for breath… (& to take stock of cost of foundations…)
SteamyTea commented on G and J's blog entry in Da Bungalow
We have a Flora Day down here they do the Fury Dance on it. -
Planning Permission, Heights of Fences, and Public Rights of Way
SteamyTea replied to Ferdinand's topic in Boffin's Corner
I am sure you have seen this, about the width. https://www.gov.uk/guidance/public-rights-of-way-landowner-responsibilities No idea about height on the boundary, some buildings are the boundary, and after quite tall. Took this yesterday. Not much more than a metre wide in places. -
While they can heat, or cool, the air by a few K, there is not much airflow though MVHR, so not much power into the room. Fitting them into ductwork is really for forced heating/cooling systems.

UFH Design - LoopCAD, Heatpunk,Spreadsheets & Copilot
SteamyTea replied to Adrock's topic in Underfloor Heating
As @JohnMo says, more floor insulation. Once you know the total, worse case, heat losses, it is relatively easy to work out the pipe spacing. I cannot think of a good reason to go greater than 16mm tubes. I think 20mm is for very long runs and lots of tight bends. Check you can do the full loop with one length, you really only want joints at the manifold. -
I have my microwave running and it is at 53 dB, it is 3 metres away. If I turn the radio on, which is about 1 metre away, the noise goes to 58 dB. Radio only 55 dB. So while I hate noise, it can be easily masked. With nothing on (so no rustling from clothes) my kitchen is at 11.5 dB, and it is quite windy outside today.

If it was at work, the the Health and Safety Act states that 'you are responsible for your own, and other peoples' safety'. I am sure there is a similar statement for doing work for people, vicarious liability is complicated though.

Was one down here, but not that recently. https://www.building.co.uk/news/hse-issues-boiler-warning-after-scalding-deaths/3092050.article

Because we have a mature democracy, that hates to make a decision.

Because they will, and are already doing so in some parts of the world. That came about from the old (late 1990's) subsidiaries. What was not foreseen, and reacted to fast enough, was the rapid drop in price if offshore wind and large scale solar. Because of this rapid drip, planning rules and grid connections are hampering the up take. Rather than piss about with subsidies/incentives, the government just needs to take planning restraints out of local authority decision makers (which they want to do). Money can be raised by increasing taxation on combustion technologies easily enough. I really don't understand why this is not happening.

Read this. https://www.aquaswitch.co.uk/blog/lcoe/ It gives a good insight to the problems.

Help! How can I make grout non porous after laying
SteamyTea replied to Oxdale's topic in Landscaping, Decking & Patios
You could coat it with a clear casting epoxy. The main problem is that epoxy is very good at crosslinking the polymers, which is what is wanted for strength, durability and stability, but makes it a bugger to stick other things to once cured. -
Probably not an engineer. Probably Level 3 technicians at best. It seems odd that that to fit PV panels, though the MCS system, a qualified structural engineer has to sign of the roof structure, but to put quarter of a tonne of hot water above people needs nothing.

Very valid points. Especially this one, how often do we hear this. What model do you have, or can I borrow your unit when you have done with it.

Welcome. I visit Buckinghamshire every couple of weeks. One of these should do you. https://www.appliancesdirect.co.uk/p/iqool-smart12hp/electriq-iqoolsmart12hp-air-conditioner

Oh dear, you have not read enough Buildhub. To answer your question, it depends on so many things. The energy stored is simple to work out 0.8 kJ.kg-1.K-1. The power emitted or adsorbed is proportional to the exposed surface area and the temperature difference and follows Newton's Law of Cooling.

Just seen this from a week ago. https://news.sky.com/story/energy-future-paying-up-front-should-lead-to-tangible-savings-ahead-13390939 So are standing charges to go up?

Part of that process must be knowing the rules. I do fail to understand why a self built house is exempt, where an identical house, but built by a developer isn't. Almost like saying that no extra infrastructure is needed if you put some blood, sweat and tears into building your own place, but the professionals must have their profits gobbled up. I think it totally misses the point of community infrastructure, actually it misses the point of community.

What was the outside air temperature? What is the air infiltration number? What orientation is the new extension? How much glazing as a fraction of insulated wall? What sort of roof is there. Does it have 'always on' electricals i.e. home entertainment, fridges, tumble dryers? Below is my house temperatures. for the last month and for last week when it was warmer. Last week was 1.5°C warmer (mean), the house was 0.8°C warmer.

It is quite acceptable to lie in a marriage, as long as it it spare the other half's feelings. Says the guy who has never married.

MVHR and cooling
SteamyTea replied to flanagaj's topic in Mechanical Ventilation with Heat Recovery (MVHR)
Not read, in detail, all the above. There is nothing to stop you designing a forced air heating and cooling system, and then adding heat recovery to it. It is done already, but it is expensive. But why do you need active cooling, you can design temperature extremes out at the beginning. It will mainly mean you will not have huge windows, but will probably make the design cheaper to build. I am about as far south as one can get in the UK (not quite the Lizard Peninsula, but close). Only only in 20 years have I had to temporarily mitigate high OAT. If it really does get too hot to sleep upstairs, sleep downstairs for a few nights. It is a lot cheaper. Slightly more expensive option is to book into a Travelodge, but check they have Aircon. -
Nursing a fridge/freezer through these temps

But greatly reduced output during the summer, if you want to use them for cooling. This is the project for a 1kWp system, South facing, by the sea in Penzance. First screenshot is vertical, second is horizontal.

Best to fit condensation drains of you can, it gives you the option to run them at a much lower temperature if you want to, though you have to be careful if running UFH(UFC really) at the same temperature, but if you have a reasonably sized concrete slab, it may take a few hours to drop the floor temperature to the dew point.
