Quick installation systems and pumping groups Meibes

Meibes pump groups allow you to quick­ly, com­pact­ly and beau­ti­ful­ly pip­ing a boil­er room of any com­plex­i­ty. In fact, this is a con­struc­tor for sys­tems with any boil­ers and heat­ing sys­tems. It is based on ready-assem­bled pump blocks. Each pump unit is a com­plete solu­tion with all nec­es­sary fit­tings (cocks, ther­mome­ters, non-return valves, bypass­es, etc.). Some mod­els may be sup­plied with­out a pump so that you can choose the right one for your sys­tem. And even in this case, the instal­la­tion of the pump takes no more than 10 min­utes.

There is an opin­ion that quick instal­la­tion sys­tems are too expen­sive when arrang­ing a heat­ing sys­tem, but this is not so. If you try to col­lect all the incom­ing ele­ments sep­a­rate­ly, then the same amount comes out, or a lit­tle more. But we should not for­get about the sig­nif­i­cant­ly increas­ing vol­ume of instal­la­tion, and this time and addi­tion­al mon­ey for instal­la­tion work. It is dif­fi­cult to assem­ble such a com­pact and aes­thet­i­cal­ly attrac­tive design from indi­vid­ual ele­ments. Heat­ing sys­tems assem­bled on the basis of Meibes units are dis­tin­guished by their cir­cuit­ry, which prac­ti­cal­ly elim­i­nates the mis­takes of installers and design­ers. At the same time, they are quite mobile and can be con­fig­ured to change the char­ac­ter­is­tics of the heat­ing sys­tem.

Design and piping of the boiler room

When cre­at­ing a boil­er room pip­ing scheme, many nuances and fea­tures of the house are tak­en into account: the area of ​​the heat­ed room, the dura­tion of the heat­ing sea­son, the total heat loss of the build­ing, the num­ber of res­i­dents, etc. At the same time, the manda­to­ry require­ments of SNiP for the instal­la­tion of the boil­er, ven­ti­la­tion and gen­er­al fire safe­ty must be observed. It is much eas­i­er to take these require­ments into account at the design stage, because it will be expen­sive and trou­ble­some to redo it. Con­sult with the engi­neers of our com­pa­ny in advance in order to quick­ly, com­pe­tent­ly and inex­pen­sive­ly cre­ate an effec­tive autonomous heat­ing sys­tem in the house.

The web­site of the Proffin­stal online store presents all the nec­es­sary ele­ments and acces­sories for pip­ing boil­er rooms, as well as ready-made mod­u­lar sys­tems for quick instal­la­tion. Our experts will help you design a heat­ing scheme in a pri­vate house, includ­ing pip­ing, instal­la­tion of pump­ing equip­ment, valves and con­trol devices.
