Heating of sacral objects in no small problem. Both aged and modern sacral buildings are characterized by large space and huge, fragmented volume. The nave is often several stories high, and large churches have a few used entrances… The aspect that always have to be taken into consideration when making decision about the way to heat place of cult, is it’s specific use in terms of whole week, relatively short, with variable intensity, on different times.
There is no need to warm up the church non stop and keep a higher temperature than its specific resting temperature. This temperature oscillates between 8-11oC. Each object should be maintained everyday in stable temperature and humidity, matched for technology of its construction. Fluctuations of humidity should be as low as possible.
Cardinal rule: temperature, and humidity in the interiors of sacral objects should go back to resting values as fast as possible. This will prevent erosion of equipment and layers of paint, by condensing excess moisture and change in humidity. This rule can be summed up by medical: Primum non nocere – First, do not harm.
Main heating functions:
- Increasing thermal comfort by mixing air
- Evaporation of moisture
- Assisting ventilation – dehumidification
Faithfull bring moisture on their clothes and shoes, they exhale large quantities of water vapor. During the whole day, hundreds and often thousands of people bring into the temple hectoliters of water – unusual thing in other objects. The faithful coming to object in warm clothes, with interior temperature too high eg. with heated benches, will sweat unnecessarily, which exacerbates the problem. The excess humidity, should be removed as fast as possible, with heat loss as low as possible. That’s why efficient heating should be linked with ventilation, preferably with air recuperation.
Central heating in churches should be dynamic!
Dynamic heating is one with quick start and rapid slowing down. You can reach effective heating temperature with low initial energy cost. Effective heating temperature is one that heats up the biggest volume of air in least time, and creates feeling of warmth in economic and discrete way. Heated particles of air rise up, together with water vapour. Recuperator draws water vapor away. Recuperation allows you to conserve created thermal energy. There is no better way. Tertium non datur.
Dynamic heaters of choice are REGULUS-system heaters – wall and duct ones.
No other heater can stand the requirements above. REGULUS-system heaters warm the area in mixed way, by thermal radiation and convection. Despite low total mass, they possess very large total heat exchange surface. Their water system is made of copper, whilst heat exchange system of aluminium. They have the greatest dynamic of work in every temperature of central heating. Perfect for fast warming up, of all types of rooms, small and huge. They cool down quickly, shortly after turning off, without warming the room further, without need (small inertia). REGULUS-system heaters are therefore not only fast, but precise warmth supply.
The way they function, has great meaning of reaching thermal comfort “on demand”. Mixing large quantities of air, moving through the heaters, quickly leads to relative isotherm. Dispersed heat radiation is also pleasantly felt. Multitude of ranges of wall heaters, different variants of height or length, guarantees the possibility of choosing the precise amount of power and free way of placement. Heating with REGULUS-system heaters is not only highly effective, but extremely easily controllable.
Duct heaters REGULUS-system CANAL – discreet and dynamic warmth from the floor.
Arrangement of church restricts many places, where sources of warmth could be placed.
Underfloor heating has no sense for many reasons. After all, completely unheated and uninsulated floor has stable ground temperature of +8ºC, but this temperature in winter is enough.
Heating has to support ventilation and evaporate moisture inside.
The alternative for heaters or their significant complement, are heaters placed in floor heating duct. Used as a curtain of warm air, cutting off specified sectors such as stalls and confessionals, separated fragment of the altar or church. Chosen, critical segments of the church can be heated up, using duct heaters.
Color of the platform can match that of the flooring. REGULUS-system duct heat exchangers, because of their small total mass, reach their full capacity in few minutes after turning the heating on. They possess high thermal output thanks to large heat exchange surface and also because of their copper-aluminium construction.
REGULUS heating systems form offer of efficient, economic heat distributors, that are uniform in terms of raw materials and unique in their performance characteristics.
