The solar installation wood Tigger with thermal buffer

[PITMIX]

Whoou you are my hero!
Once again you took action before me regarding your bathroom radiator.
I hesitated to use my recuperative fan coil to connect it to a solar collector on the south facade of my house.
Tell me, does it even heat your radiator in the weather?
I see that it heats 3 ° C ext, certe but it gives what in it is not nice?
Can you give measures?
I know I'm impatient but here I'm wriggling like a fish.

Thank you for the information will be necessary that I get back the barraque!

Hello,

it heats a little if the weather is overcast, it depends if the sun comes out from time to time and also following the outside temperature.

the best is still the sun, even by negative temperature outside it heats as the sun hits the sensor.

1 speed on the circulator, plus it is a very short circuit, just through the wall, setting the thermocontact 35, as soon as it turns it turns it turns if a little sun on the sensor.

especially that it heats the bathroom which is a small room, instead of radiator dryer towel 1000watts.

at the moment, it does not heat much, always clouds.

ps: heee pitmix, no need to break the whole house, just a hole of 100 to do to pass the pipes and the electric cable.

The solar collector, you bought it or it is a "house" model

[PITMIX]

No I said that to put a PC extra thin as yours under the tiles.
My floor is not very straight so one day or the other I will have to turn the tiles and make a patch. That day I intend to install a PC at the same time.
For the radiator it's great to see an installation turn because in the absence of a PC at home, I thought why not do what you did.
I wonder if it is really necessary to put an expansion tank and inflate the circuit to 2,5Bars.
The glycol circuit of my solar water heater is at 0bars at night and does not rise above 2Bars in bright sunshine. Certe I have an expansion tank but it is inflated only 0.5bars.
From time to time I turn my circuit in full summer in open vase mode.
At the top of the sensors I connected an iron box (baby milk powder) on a valve that serves as a vase open to the outdoors. It is to debull the circuit.
I tell myself that with the little liquid in your circuit a safety valve and a can of recup would suffice just in case.
Do you empty it in summer?

[tigrou_838]

hello, the sensor, I had recovered some time ago, in a store that did not want more, for a very very low price.

for the circuit, I prefer to turn in closed glycol, in the cicuit there is more or less 5 liters, for the winter in the East it is better, the summer I do not empty, in summer when there is clouds and temperature below 14 ° the system turns anyway a little.

like winter, it always stays at 2bars.

this will warm the house with the bathroom door open, and of course not to turn the floor heating.

for my pc, I had before doing the work, 4 pieces, I broke the partitions to make a piece of 50m2, a first small régreage to put them at the same level, then poses pipes, then régreage to drown them pipes and finally glue and tile.

and for the continuation of the tanks of 800litres, here is a picture made last night with my telephone.

Hi tigger
I have exactly the same configuration as you for 50m2's large room since I also broke the walls, kitchen, hallway and bedroom, but with glazed tiles.
I saw that they sell Howatech at leroy M ... they are 5m2 kits extensible to 15m2 that arises in place of the radiators. Did you do this or did you do something like a traditional PC?

[tigrou_838]

Hello,

for the tiling I did everything by electric hammer burineur, kind of big drill.

it was old tiles and I had four different types, not the same level.

I had ordered directly to the factory to get a price.

having no central heating, I made two normal plumbing nurse with circulator, thermostatic valve big passage etc ..., like traditional pc on heat pump.

and here is my last little DIY, 100w panel completely autonomous solar tracking for self-consumption, do with what hangs in the garage and a lot of recup.

[PITMIX]

Hi tigger
Do you plan to equip the engine to make an autonomous solar tracker?
Wiper motors? Do you realize the electronic circuit yourself?
What I have seen on the web so far is prohibitive in terms of price.
At home I would have liked to do that but with a mirror to illuminate the north face of the house.

[tigrou_838]

hello, it's already done, look at the last picture, we see the micro motor, (which works between 1 and 6volt) no electronics, the two cells are mounted against each other, or back against back , so East and West, the branching and in opposition of pole, ie most of the West cell on the least of the East cell, and the least of the West cell on the plus of the cell is, and at the the engine.
Since the two cells will never receive the sun at the same time, and each cell has a certain resistance, it is all good for the engine.
I am transforming an old servomotor of reduced model to put in place of the motor.
this kind of system can also adapt to a mirror.
it's like everything, it takes a minimum of sun to turn, and also chase rubbing.
and I also had to look on the net and in my books, but not find anything simpler than what I just did.
it's great when there is just a ray of sunshine and you can see the engine running slowly to catch up with the sun.

A+
