Cost difference between gas boiler and ASHP
SteamyTea replied to Moonshine's topic in General Plumbing
So probably comparing a basic combination boiler with a proper HP installation. Why don't they compare a system boiler to a non MCS setup. -
Too late, already been told off and had a post deleted. So much for bringing light relief to these troubled time.

Cost difference between gas boiler and ASHP
SteamyTea replied to Moonshine's topic in General Plumbing
Did that include digging up an existing floor, insulating and recasting? And did he cost in connecting to the gas main if it is further away than the free connection. Was going to visit £20,000 to connect my house. One of those things that cannot really be compared purely in hardware prices. -
Single room MVHR. And internet disconnect.

Look at this. https://www.britishceramictile.com/how-to-tile/ceramic-vs-porcelain-tiles Seems that the glaze is a separate thing. -
Read up about it here. https://en.wikipedia.org/wiki/Thermal_radiation The calculate that it isn't worth the bother as the temperature differences are too small. Thinking about it as visible light is not how it works, we can't see sound and radio waves, but we can reflect, bend and focus them. The smaller the gap between the radiative and adsorption surfaced the more energy transferred. Conduction is only radiative transfer, but at the scale of electrons turning into photons.

Solar PV + Tesla Powerwall (or storage battery)
SteamyTea replied to magutosh's topic in Photovoltaics (PV)
At 11p/kWh, that is about the same as my E7 night rate and about 11p saving over my day rate. Trouble is I only use between 1 and 2 kWh during the day. So £9000 / £0.11 = 81,818 kWh 81,818 kWh / 2 = 40,909 days 40,909 days / 365 days = 112 years The price needs to come down tenfold. -
MVHR- real world performance?
SteamyTea replied to DragsterDriver's topic in Mechanical Ventilation with Heat Recovery (MVHR)
Steam is condensate and will not disappear, it will coalesce on surfaces, just like vapour (which is a mixture of gas and condensate) will if the surface is colder than the transition temperature. -

Eh? You need to clarify that a lot more. -
Few more leaks and you can charge plumber's rates.

Get a flexible.

What cable should be used to extend CT Clamp cable?
SteamyTea replied to Marvin's topic in Photovoltaics (PV)
Initially I thought that, but as it is measuring ripples won't they get cancelled. Why do you need to extend it? The extra resistance may change the readings. -
Shadow gaps instead of skirting. Save twice.

Hot return circuit, how to control it.
SteamyTea replied to Russell griffiths's topic in General Plumbing
Is cable that cheap? -
Oil fired combi, UF heating and radiators
SteamyTea replied to gdal's topic in Boilers & Hot Water Tanks
How much insulation is going under the floor? You will if you size the ASHP correctly. 12, 18 or 25 kW is the power, this is independent of the technology used to generate it. -
Is there a buffer tank installed? Turn off the legionella cycle, it is pointless.

This will clear out your bowels and washing your hand will be the last thing on your mind. -
The 2007/8 financial crisis changed that view, as did Starbucks back in the 1985.

Enforcement: a new twist on an old story.
SteamyTea replied to ToughButterCup's topic in Planning Permission
What is the build cost: £10,000 £50,000 £100,000 £500,000 £1m No, just make the objectors pay. There could be a surcharge on mortgages that keep the borrowings down. It will be interesting to see how many farmer's try and sell off land for building when they stop getting paid for just owning it, and to claim new subsidies they will have to improve it. Valuing nature is pretty easy in concept, ass is valuing public spaces, but the devil is in the detail. -

Enforcement: a new twist on an old story.
SteamyTea replied to ToughButterCup's topic in Planning Permission
Not the Government as such, it is LA's and the NIMBYs. If a Government gets involved, all that will happen is that the price goes up. My alternative to to get the LA/Objectors to pay for the lost value, to the person who wants to build, but has been refused. That will sharpen the mind. -
Enforcement: a new twist on an old story.
SteamyTea replied to ToughButterCup's topic in Planning Permission
Just for a laugh, let us assume that we double the number of houses in the country, so from around 35 million to 70 million. That would be near enough one house per person. We would double the land area that is housing, but not the infrastructure, we would not be doubling the population. So we would use up another 2% of the land area. We really need to reassess our thinking on planning.
