Multi-family/social housing

Multi-family housing has two aspects that strongly distinguish it from single-family housing: energy generation is centralised and the "time factor" is of vital importance on site.

For the professional or the developer, the objective is to offer the best product possible that is suited to the standards of the building project, whilst also implementing solutions that are easily reproduced on a large scale, in order to maintain profitability. Performance in terms of energy consumption, appearance and ease of product use are major considerations.

Generator parts

In multi-family housing, the boiler is placed in a technical space restricted to professionals, located below-ground or at roof level. It may constitute either one lone generator that supplies all necessary power or a series of generators that may be combined with renewable-energy systems.

Heating

Sanitary

  • If heating and hot-water generation is centralised (with an accumulation device) the COMAP 899 safety unit, made of stainless steel, completes and secures the installation.
  • Even if domestic hot water production is done separately by using individual Logotherm modules from the Meibes range [see (3)], it is also necessary to place a charge tank in the technical area to guarantee comfort and hygiene for occupants (particularly during consumption peaks).

Primary networks

In multi-family housing, the size of primary networks is directly linked to the method of domestic hot-water production. Depending on whether or not production is centralised, different solutions may be put into place. 

Heating

  • The primary loop (Ø 42 to 108) and riser columns (Ø 32 to 76) may be installed with pipes and fittings from the XPress range, in carbon steel.
    If a Logotherm unit is used, the extra power necessary for the drinking water network must be taken into account when sizing the columns in the primary network (larger diameter).

Sanitary

  • Domestic cold water columns may be built with MultiSkin pipe (Ø32 to 63) and SkinPress press-fittings for multilayer pipe.
    If hot water production is centralised, cold and hot drinking water columns may be built with the same product range. Loops may be built in insulated multilayer pipe or pre-sheathed, insulated PEX pipe.

Interfaces

In multi-family housing, like the sizing of primary networks, interfaces are selected according to whether or not hot water production is centralised. For its part, secondary distribution (by simple splitters or manifolds with built-in control units) is determined by the type of emitters used.

Balancing

In multi-family housing, balancing is essential to guarantee that all occupants are comfortable and the building is energy-efficient.

  • On the primary heating loop, the correct Ballorex 750B valves for the loop's nominal diameter may be installed.
  • On the heating column, Ballorex Delta differential pressure control valves (DPCVs) may be installed to guarantee the right pressure drop value within the whole column.
  • On secondary heating networks, differential valves are built in to Meibes Logotherm units.
    If hot water production is centralised, Ballorex 750 valves regulate flow to individualised central heating modules as well as on the water return loop.

Secondary networks

In multi-family housing, the product's cost and efficiency on-site are important criteria when choosing the solution to put in place for secondary networks. Appearance is also taken into account, in accordance with the project's level of standards.

Heating (radiators)

Water

  • Networks that are encased in slabs may be constructed with COMAP BetaPex pre-sheathed pipe (Ø12, 16 or 20, depending on use) and PexPress press-fittings.
  • Exposed networks may be constructed with COMAP MultiSkin  pipe (Ø16) and SkinPress press-fittings for multilayer pipe.
  • The system may easily be connected to PEX networks with COMAP's exclusive couplers.

Regulation and parts for emitters

In multi-family housing, the product's cost and efficiency on-site are important criteria when choosing emitters and parts. Appearance is also taken into account, in accordance with the project's level of standards.

Low-temperature underfloor heating

  • The complete PLANEA and EXACT systems from the Biofloor range allow you to put in place a whole LTUH installation.
  • The Biofloor 9000TP system of modular manifolds acts as an interface - see (2) - as well as temperature control within each room, with its wireless control feature.
  • If radiators are also installed, the COMAP 9100 kit enables easy management of two networks even at different temperatures (that of the low-temperature underfloor heating system  and that of the radiator).

Radiators

  • With standard, horizontal-type radiators, the network may be assembled with COMAP MultiSkin insulated pipe and SkinPress press-fittings for multilayer pipe.
  • Thermostat components from the Comap range may be installed on each radiator: a thermostatic head, like the Senso, with customisable colours; a thermostatic body; and a Series E lockshield valve with exterior threading and compression fittings for 839 multilayer pipe.
    On a 100% PEX network, installation of the Senso thermostatic head requires the COMAP 558 conversion kit.
  • For towel warmers: installation is the same, with dedicated COMAP 445 Series E thermostatic bodies and 839 fittings.

Water treatment and quality

Water transports energy within a heating and air-conditioning system, and it is also used in multi-family housing for bathing, washing-up, cooking and more. It is also consumed by itself. Its quality is therefore critical, both for technical equipment and for occupants.

In multi-family housing, installing a COMAP sludge collection unit completes the initial outfitting with a large-capacity retention device on the primary circuit. It guarantees that impurities from the looped heating circuit do not recirculate. The risks of total or partial blockage and of premature corrosion due to differential airing are limited.

Depending on water hardness, a large-capacity COMAP water softener may be installed to prevent malfunction linked to calcium deposits.
