A car workshop is a specific building, which is often divided into two parts – extensive halls for vehicle repair, and several office rooms and sanitation facilities. Heating this type of building is a big challenge, generating high costs. What kind of receivers are worth choosing? Or maybe you need to use point sources? All pros and cons should be taken into account.
Central heating with radiators – an idea doomed to failure
A classic heating system with radiators will certainly fail in workshop halls. The process of warming up to the set temperature of a large volume of air will take a very long time. In addition, open entrance gates will effectively hinder it. For this type of buildings, a definitely more dynamic heating is required, which will allow to quickly deliver warm air directly to the zones where the workers stay.
Direct air heating
One of the most interesting ideas for the implementation of heating in a car workshop are air furnaces. They burn various types of fuels – coal, gas, oil (fuel or diesel oil), and can also be supplied with electricity. The heat is transferred directly to the air directed to specific room zones. In the case of more spacious workshops, the furnace should be connected to a system of channels distributing warm air in the building.
Another method for quick air heating are mobile heaters powered by gas, oil or electricity. These devices are placed in the usable area of the room. Their big advantage is the ease of use and no assembly required. However, it is necessary to ensure constant fuel supply and proper flue gas discharge, which in some cases hampers daily operation. Continuous use of electrical models generates very high costs. You can read more about this topic in the article "Types of air heaters".
Alternative method – infrared heaters
Infrared heaters heat people and objects in the rooms, without heating the air. They are based on the phenomenon of emission and absorption of infrared radiation. The offer of manufacturers includes gas and electric infrared heaters. Their use allows you to quickly get thermal comfort of people staying in the room. The perceived temperature is higher than the real one.
Compromise combination – water heaters
Water heaters are a kind of compromise that combines the use of a standard water heating system and dynamic air heating. Similarly to air furnaces, they allow for directing a stream of warm air to work zones, and, at the same time, they do not require fuel supply and fuel gas discharge. Then, you can also connect to a traditional system the heaters that work well in small offices and staff rooms. Proper directing of air streams in the workshop will reduce energy losses. The heat will not escape so quickly through the open gates. In tall buildings it is worth considering the use of destratificators, which will inhibit the migration of heated air upwards.
When planning heating of a car workshop, special attention should be paid to operating costs. Radiator system is not the best idea, and mobile heaters may generate high costs. It is worth analysing practical alternatives in the form of water heaters and air furnaces.
