About the slab. Does anyone know how heavy a 4 inch thick slab reinforced with wire mesh can withstand?
I do have a porch but it is only 4 x 8 ft. I doubt it is worth the trouble of digging and making a hole in the basement wall, more difficulty to insulate the tank
If I split the tanks in 2 (within my technical room), I wonder how I could place the inlet and outlet vs heat exchanger coil... Connection between the two tank I guess should be at the bottom. Martin Eau, soleil, le vent[ Parent ]
If the slab was properly done, you should have no worries putting a water tank on top. Tap on the concrete to see if you can detect any hollow areas, if any are present then you have some worries.
Location of a pipe for balancing the water level isn't critical. Water seeks it's own level. Personally, I'd build one large tank with an insulation barrier between them. You create less exterior surface area that way and a lower need for heavy exterior insulation. The top is probably the most critical for insulation, as heat rises. That would save you from any additional heat load in your house in the summer.
Heat exchangers should be placed near the top for heating applications, (pool, DHW) and at the bottom for solar panels. In other words you want to utilize the hottest part for your heating applications and heat the coolest part. Of course if you go drainback, that is inconsequential, pickup at the bottom, and return at the top. [ Parent ]
