Hello,
I do not know if I will get there but I would like to do as many things myself (for financial reasons), I am in the process of completing the connection of the radiators to the three floors and I bought a second-hand boiler oil with coupled boiler, expansion tank and circulator), I am looking for a standard boiler connection diagram (simple for the novice that I am).
1st QUESTION
Is it useful to provide a 15 mm copper pipe for the supply of the propane water heater (which does not allow a flow greater than that which a 15 mm pipe can provide for heating domestic water) from the rest of the cold water distribution so as not to see the flow of hot water collapse when cold water is run (if same distribution line)?
2nd QUESTION
From the counter (from the non-return valve exactly), what diameter copper pipe must be provided in order to:
- Ofsupply the boiler (1 pipe diameter ???)
- distribute sanitary water (2 pipes: 22 + 15 mm)
- (r) bring the water from the radiators (2 pipes of 22 mm traveling with the sanitary water towards the back of the house and 2 others of 22 mm running directly through the ceiling of the cellar towards the rooms front of the house: ground floor and two floors)
3nd QUESTION
Is the pecuniary interest of converting the burner of the oil boiler by a pellet burner real ( http://www.alterenerg.com/html/convertible_aux_pellets_oui-no.html )?
Thank you again for your intervention!

Standard oil boiler connection plan
Connection plans for simple or complicated boilers abound on econology, on the Internet and on the instructions for many commercial oil, gas or other boilers !!!
It is good to understand the scientific reasons for installations to avoid basic errors, especially when looking at real installations and avoiding unnecessary complications.
.
Pipe diameters are calculated based on acceptable pressure losses, flow rates, pipe length, necessary (like the inverse of the power 5 of the diameter and proportional to the length and abques on posts I put on econology, from google and wikipedia).
So not too small (2 times smaller gives 32 times less flow) or too large (excessive prices)).
For an average house, the diameters given should be acceptable, at random.
For pellets see price of pellets on econology, variable according to regions and suppliers, between 230 € and 300 € per ton, with 2t equals one ton of fuel, ie 480 to 600 € against 860 € fuel or even more at the moment he climbs well !!
The pellets will also climb behind !!
Finally, I repeat my hobby horse, which I use, the free wood and plants that I see everywhere, just collect, dry in the sun and burn in a boiler, insert or stove !!
Commercial wood in logs is 2 to 3 times cheaper than pellets !!

If you prefer to do it yourself for budget reasons you are completely in the spirit of this forum, but be careful not to do too much nonsense because in the end it can be expensive!
By typing boiler plan in google or the search engine of the site you will find your happiness I think.

I recommend this very good site: http://herve.silve.pagesperso-orange.fr ... uelgaz.htm
For your other questions:
1) No, it's not worth it. The network pressure is sufficient not to have to double the pipes ... To say: with us the water supply is done in 12/10 mm and that is enough ...
2) You should find the answers here: http://herve.silve.pagesperso-orange.fr/plan.htm
The diameters of the cold or hot water pipes in 14/16 mm will be more than enough (as said above we are in 12/10!)
For the heating circuit it will depend on the precise circuit, to do well would be necessary to make a precise calculation of the pressure losses of your circuit (few heating engineers do it with precision for individuals): http://herve.silve.pagesperso-orange.fr ... e%20charge.
22/20 is often enough. Balancing the network is more important than diameters!
3) Yes it is interesting a priori only because I have strong doubts about the efficiency of the conversion, a pellet boiler is very specific ... especially to be able to clean the exchanger regularly (the pellet does more smoke than fuel oil)
That's all the time! Good luck

Fuel / gas boiler with two circuits and DHW production.
In this case, one of the two circuits is a circuit with radiators and the other a floor heating circuit. The latter is controlled by a 4-way valve while the radiator circuit operates at boiler temperature. The diagram shows the possibility with a motorized 3 and 4-way valve. The underfloor heating circuit is fitted with an aquastat of maximum temperature (9), generally limited to 50 ° C. In this case, if the flow temperature exceeds 50 ° C, the aquastat switches off the circulator (phase cut in the junction box 7).
Legend:
1 regulation
2 motorized 4-way valve
3 motorized 3-way valve
4 circulators
5 differential valve
6 filling backflow preventer
7 junction box
8 safety aquastat maximum temperature for underfloor heating (50 ° C)
9 start probe
10 DHW probe
11 safety valve

Here is the connection plan for sanitary water and central heating nearing completion at home.
Could someone tell me:
1. where I should place stop / purge valves on cold & hot sanitary water pipes (to or back from radiators too?)?
2. how connect to non-return valve downstream of the water meter, the domestic water pipes (water heater supply in 15 mm and cold water in 22 mm) and boiler supply? I have soldered everything in copper to copper so far. Use a "console" and twin cones? In what initial diameter?
3. There are 2 radiator circuits, one for the north of the house (3 radiators) and another for the rest of the radiators.
How should balance the network in these two circuits during commissioning (only one pump)?
Thank you for your help.
