Regulus-system Canal
Discreet heat
The buildings that are currently constructed, both residential and designed for business activity, are continuously better insulated and, consequently, they require less and less heating energy. At the same time, users’ expectations as for maintaining a friendly microclimate in their environment have grown significantly. And so did the range of alternative sources of heat.
In the course of detailed designing of modern interiors and perfect planing of their functions, the designers more and more often face a significant dilemma: how to heat a room? Where to place radiators – even the smallest ones? The heating, indeed, is indispensable, and any place on the wall planned for the heaters seems a waste. Moreover, that element of the interior, forced upon the designer, can ruin the effect of the perfectly designed whole. Floor heating is normally considered as an alternative. However, the application of floor heating is not possible everywhere. Floor heating has extreme thermal inertia, which is its significant disadvantage. The users do not always receive a required amount of heat when they need it and, what is more, floor heating is not very useful in the transitional autumn – spring season or in the periods when heating is needed from time to time. Health-related reasons: cardiovascular diseases, susceptibility to allergies or joint conditions, also disqualify the use of such heating. It is not recommended to stay long in the rooms heated by use of floor heating. Floor heating cannot be used with parquets or floor panelling either, as those materials have high thermal resistance.
When the use of wall-mounted radiator is not possible and there are contradictions to use floor heating, radiators installed in floor recesses become another possible option.
In addition, in the rooms of very big cubic capacity, where floor heating has been installed already because of the absence of any contradictions, canal heat exchangers can support the heating process actively as a heat curtain located along the external walls or as a heating unit quickly responding to a cold snap. Regulus floor heaters can heat the room almost instantly after being switched on. Canal heaters can be fed as the first ones in the same system as floor heating.
The heaters placed in the floor recesses offer a perfect protection for the interior against cold next to terrace doors, balcony doors, under large glazed surfaces, in winter gardens, entrance enclosures, lacings, etc., everywhere where there is no space on the wall for a standard central heating radiator.
The Regulus heating canal system proves to be very effective in office entrances and halls, sports facilities, mainly sports halls and swimming pools, in commercial units, exhibition centres or production buildings, namely in all places where exterior doors can be opened frequently or where we wish to avoid steaming up of window panes.
The Regulus Canal-system (+) is the response of REGULUS®-system company to new trends in interior design and growing users’ requirements. The Regulus®-system along with hitherto manufactured copper and aluminium radiators and copper towel radiators forms a consistent market offer in respect of materials, economical, with very good prices and long-life products.
Canal heater operation Regulus Canal-system heaters are mounted on stands that are fixed to the canal section. This allows for a free space to be achieved between the bottom of the section and the lower part of the heater thus enabling free air circulation – inflow of cold heavier air and discharge of warm lighter air.
Canal heating use examples
Components of canal type heating system
I. CANAL PLATFORM - (grill, “grid”, outlet)
Is made as a roll, i.e., the platform can be rolled up (a very practical solution for canal maintenance, transport, storing after heating season, when after-season platforms are used)
Maximum length of one platform roll section up to 7.00 m
Material: wood or aluminium
Fix type means that the product is available as a rigid platform.
Maximum length of one section up to 2.00 m
Material: stainless steel, black nickel plated steel, wood, aluminium
 |
 |
a/. Wooden platforms:
Platform rungs are made of oak or beech wood, in the form of elongated “bones”
Platform width - 243 mm, 293 mm and 343 mm – with the frame: 250 mm, 300 mm and 350 mm, respectively
Rung width 7 mm; clearance between rungs -14 mm
Condition: wood coated in transparent nitro laquer
Application: together with parquet, floor panels.
 |
 |
b/. Aluminium platforms:
Platform rungs are made of sections – aluminium double-tee bar;
Platform width - 243 mm for the “250” canal or 343 mm for the “350” canal
Width commercial symbols: 250, 350 – relate to the dimension including the frame!
Section is coated in transparent powder paint or, more often, RAL - pearl silver or any colour according to RAL at customer’s request without any extra charge.
Section (rung) width 7 mm
Clearance between rungs – 7 mm, 10 mm or 13 mm (we recommend using 7mm spacing with an additional third line of spacers in the platform axis in actively-used passages). Possibility to make the section as a hardened type; t = hard.
Application: any type of floor - ceramic ware, solid surface veneer, lining, wood.
c/. After-season insert (solid)
A platform substitute used as a solid canal closure after the heating season is over in order to protect the canal interior against contamination.
After removal of the open-work structure platform, we insert a replacement solid platform.
The user can cover the solid platform with the material used as the flooring thus hiding the canal interior after the heating season.
The cover for the platform can be made on the basis of a retained drawing of the rest of the floor (the same arrangement of parquet flooring blocks, ceramic tiles, etc.)
The platform consists of the frame of a relevant height and a metal plate bottom; maximum length of one solid platform section up to 2.00 m.
II. PLATFORM FRAMES
- Mounted on the canal section on a floor level, supporting the platform covering the canal trough. Furthermore, it is a component that carries the load from the platform onto the floor (base). It should be installed together with the canal sections before making screed (stabilisation of the sections and dimensions).
Typical frame outer dimensions:
Width - 250 mm for narrow and single exchangers
- 350 mm for wide and double exchangers
Total heating canal length, i.e., section plus frame, is unlimited since the segments can be connected together into a long channel.
Individual frame segments – maximum length 2000 mm
The frame is made of three types of aluminium angle sections.
|
a/. Universal frame – for platforms made of aluminium and wood, rung height: 20 mm |
 |
|
b/. Frame with a shelf – for platforms as above, an additional shelf on the outside of the angle section is to stabilise the flooring-and-frame edge, used with ceramic floors and floor panelling (they are supported by the angle section shelf). - dimensions of angle section with shelf: 24.5 mm x 25.0 mm + shelf: 10.0 mm |
 |
II. CANAL PARTITION (blind)
Made of a galvanised sheet strip, powder painted (RAL 5008).
It is placed vertically on the upper inner heater edge. The blind divides the canal into the cold air inflow area and forms a funnel for discharge of the air already heated by the heater.
The component is strongly recommended as considerably improving the effectiveness of heater operation.
- Partition height between 50.0 mm and 100.0 mm; one section length: 1000.0 mm
IV. CANAL TROUGH (trough and section)
Made of galvanised sheet coated in powder paint RAL 5008 (dark blue)
Cross-section dimensions, standard:
Height
h= 190.0 mm for SOLO, QUATTRO Mini Heaters without canal partition (blind).
h= 265.0 mm for SOLO, QUATTRO Maxi Heaters and for low heaters fitted with canal partition.
Possibility of making canal trough of a different height between 130.0 mm and 500.0 mm.

Trough width: |
 |
Important!
The selected total frame length together with the platform and the total canal trough length should be identical.
The total canal length should exceed the length of a heater installed inside or the total length of all heaters installed in the canal though, and thus:
- 200.0 - 300.0 mm trough longer than the length of a single heater
- 300.0 - 500.0 mm trough longer than the length of two heaters installed in series in one canal
- 200.0 mm more for every additional heater installed in series
V. FITTINGS
VI. HEATERS – CANAL EXCHANGERS
Made of the pack of 2-4 horizontal copper pipes DIN15 connected by collecting pipes at the ends.
Aluminium slats packed tightly on the pipes.

Canal heaters can be in one of two widths 90.0 mm and 155.0 mm with heights from 70.0 mm to 135.0 mm.
Furthermore, standard Regulus-system radiators in reinforced make and without upper shield in canal can be installed in deep floor recesses.
Such radiators (R6 h=56 cm, R4 h=36 cm, R2 h=16 cm) installed in the canals have heating power approx. 20% lower than the commercial power due to worse convection conditions in the canal.
Every canal heater is fitted with two 5 cm high stands and a manual 3/8” vent. Those fittings are included in product price.
Maximum length of one radiator: 2000.0 mm
Canal heater types:

High radiators installed in the canal trough should be mounted on the 100.0 mm high stands. Installing of a two high radiator pack in the canal trough is acceptable.
Canal heater control:
Option I: thermostatic valve (in the canal) with a capillary probe mounted in a desirable place outside the canal.
Option II: cut-off and throttle valves (for system hydraulic control), the radiator operates together with a boiler controlled by a boiler room sensor.
Option III: solenoid valve with a remote portable sensor.
DIN18 (3/4'') pipe is recommended for making branches to connect canal heaters. If there are more than one radiator in the canal trough, they should be connected with the main in parallel. Please, avoid connecting the radiators in series.
Heating canal platforms can withstand standard loads acceptable in living units and loads occurring in passages designed for people.
Our Company manufacture canal heaters of lengths up to 2000.0 mm to customer orders. Furthermore, the Company does not impose any limitations relating to the heating canal total length. A desired length should be specified within an accuracy of 1.0 cm.
Canal heaters, frames and platforms are calculated in running meters also within an accuracy of 1.0 cm, whereas the value of the canal trough is calculated as the multiple of a 500.00 mm long module.
