Tips to use less energy at home

[elephant]

In fact, the bottom of the question was whether this very interesting gain concerned old or poorly insulated boilers, or if it was useless with a recent boiler? Rich idea bubble plastic, but I wonder if other materials would not be even more efficient thin polystyrene style (3 to 5 mm, several layers), or this white packaging plastic, but quite compact (I do not not know what it is called). How thick did our friend use?

The other question is to know: yes, if the boiler is in the cellar, we certainly win, but if it is in the bathroom, this energy is not entirely lost (I am a snug who keeps the bathroom - well insulated - at 20 °, which makes it go up to 23 ° when I use it, using a fan heater and a programmer)

my water heater will be 30 years old this year and is in the boiler room.

So I think that the isolation of it can only be positive, I just hadn't thought of it! I found the post concerning the said coat! ok, for the principle.

good

the explanations to isolate the boiler

boiler in the house 200l
5/6 years of age
2 adults a child
the wall is warm in the morning so loss
insulate with 200mm of glass wool covered with a geotextile film
(glass wool recover from a neighbor who wanted to throw it away) otherwise I would have taken something else not top glass wool.




the boiler is fixed to the walls

You have to measure the perimeter of the boiler, cut the glass wool according to the perimeter you have to be precise enough otherwise you don't cover enough or you have too much insulation and there is space between the boiler and the wool of glass.
Make notches in the insulation for the fixings in order to pass the glass wool between the walls and the boiler.

to keep the glass wool in the boiler I stick double-sided tape on the boiler.


Once the glass wool stick on the wall measure the diameter of the boiler and insulate it and make a cover to insulate the upper part.
The brown tape is to prevent wool from spreading around the house.
I stuck the cover on the insulation of the wall

well i hope i was quite specific.

so explanation before consumption of 6kw for 20 ° in the house
after insulation 5kw I also lower the thermostat because the water was too hot so the power consumption is 4kw

measurement made the second of July

I attended a conference on energy saving
one person said that insulating your boiler means saving the purchase of a solar panel, because the annual losses of the boiler correspond to the annual production of a panel.

(great idea)
Thank you Recup, for the additional info.

I have two PCs: a normal one, and a laptop lying around in a corner (offered by Total ... 25 years of seniority)
I just measured the power absorbed by the normal office pc: 150 watt
I turned on the laptop it eats + - 40 watt
Okay, well we can earn 300 kw per year by doing the exchange.
I measured the insulation of the electric water heater ... 3cm! which stingy band at Siemens (we can change that )

Ah! 200 mm of glass wool is not nothing: but at the price or you got it, the experience was worth trying, if only for our construction.
System quite valid in your case because the boiler is in the boiler room (it's weird, few people think of recovering heat from the boiler room)
I still think that when it is placed in the bathroom, it is less necessary (and the closer the boiler is to the shower, the less hot water we lose waiting for the hot water to arrive)
That said, to improve the existing situation is good. Have you thought about insulating the pipes too?

Part of the pipes are in the walls, not insulated
The water heater is in the cellar

[Hasardine]

in my case, I transformed the boiler room into a second toilet, I put the dry toilets there, I put the washing machine, and the spreader (laundry, what!) more, the door is very often open, winters at least, suddenly the boiler heats the room and the hallway and staircase!

I am however lucky that the pipes are all insulated.

Hello recup

so explanation before consumption of 6kw for 20 ° in the house
after 5kw insulation I also lower the thermostat because the water was too hot so the power consumption is 4kw

We already talked about it on another post, be careful if you lower the temperature too much there is a health risk.

prophylaxis

The bacteria's habitat is usually water. Legionella is capable of development in protozoa and can be carried by amoeba cysts. The amplification factors are a water temperature between 25 and 45°C, stagnation of water, the presence of biofilms, organic debris, corrosion products and of course microorganisms and in particular amoebae.

The contamination vector is the aerosol with droplet sizes from 1 to 5 µm. The search for sources of contamination in collective establishments using hot water (showers, whirlpools, installation of air conditioning and air treatment) is essential and requires often difficult investigations. The plumes of cooling towers are often implicated. The fight against the tanks of Legionella, and of the protozoa which host them, uses chlorination, thermal shock (Duration of decimal reduction (division by 10 of the number of germs): 20 min at 55 ° C, 6 min 57.5 ° C, 2 min at 60 ° C) modification of systems trying to avoid aerosols, removal of external sources of Legionella.
However, it is in the design of the installations that the most effective prevention lies: humidification of the air conditioning can use aerosols of healthy water or better steam, plate heat exchangers for water heating , sufficient temperature in hot water tanks (but not excessive to avoid burns!)…

A+

the boiler heats up the room as well as the corridor and staircase!
