mais difficile à trouver l'installateur. C'Est un excellent produit (j'en ai 4 pareils déjà) mais malheureusement, nos services dégradent partout-partout, surtout les électriciens... encore pas installé!...
I purchased this glycol pump as part of the build your own, which included the manifolds pump, expansion tank, air separator and basic plumbing supplies. I was very happy with how everything arrived together and the install was straightforward just from looking at the pictures. The glycol pump makes it easy to charge the system, and took a lot of the guesswork out of setting it up. My garage now has toasty warm floors.
