Understanding the Pipework Installation Options for Your Central Heating System

Central heating systems are crucial for efficient climate control in commercial and residential buildings. However, their design is not simple, and the cost of purchase and setup can be high. Therefore, if you are planning on installing this network in your home, you must think about numerous factors before proceeding. One of these critical aspects is the design of the pipework. If your choice of the arrangement of the channels connecting the boiler and radiators is not ideal, you will not enjoy optimal efficiency. Here are primary options that you should consider during your pipework installation for your central heating system.

Single Pipe Loop

The single pipe loop is a simple system. In general, this design consists of a single pipe which runs from the boiler to each of the radiators in the central heating structure. The tube carries heated water from the furnace, and it branches off at the first radiator. Once the heated water passes through the radiator, the cooling water flows out and re-joins the main piping from which it branched. The same water flow design is repeated at every radiator. This single pipe loop is favourable because it is inexpensive. However, it is inefficient because the water at the first radiator will be hot while the last one will have mostly cooled water. 

Feed and Return Pipework

The feed and return pipework is also known as the double loop. The design is similar to the aforementioned single pipe loop, but this variant is more efficient. The feed pipe carries water from the boiler and branches off at the first radiator. However, instead of the cooled water re-joining the main tube, it flows out into a separate return pipe. The advantage of this design is that the radiators will have equally hot water, which promotes uniformity in space heating. However, you should note that the number of radiators that you can have in your building will be limited by the size of the central heating pump.

Microbore System

The microbore system provides probably the highest level of efficiency for central heating. A typical network consists of a feed pipe which carries from the boiler. This large pipe passes through a manifold where the water is redirected to smaller pipes. Each of these tubes goes directly to a single radiator, ensuring the preservation of heat. Separate pipes return the water from the radiators and join at another manifold.
