Exhaust gas in the underfloor heating system is a crucial step to ensure that the heating system operates more efficiently and safely. Exhausting can be done by means of a small back basket or a water separator, both of which have their own characteristics and application scenarios.
--Exhaust mechanism of the small back basket
The small back basket is an automatic exhaust device in the floor heating system, and its function is to automatically discharge the gas in the floor heating pipeline. The small back basket has a built-in gas sensing device, which can accurately judge the gas in the pipeline and automatically remove it, so as to avoid the air resistance affecting the normal operation of the system.
Pros:Automatic exhaust: The small back basket enables unattended automatic exhaust.
Easy to install: Small baskets are usually small in size and relatively easy to install anywhere in the system.
Low maintenance costs: The failure rate of the automatic exhaust device is generally low, and the maintenance cost is not high.
Cons:Local exhaust: The small back basket can only exclude gas near the place where it is installed, and may not be sufficient for the overall exhaust of the system.
*Relatively high: The technology of the small back basket is relatively advanced, and it may be slightly higher.
--The exhaust mode of the water separator
The water separator is mainly used for the distribution of hot water in the floor heating system, which can be configured with manual or automatic exhaust valve to realize the exhaust of the system.
Pros:Good exhaust effect: The water separator is located at the water supply and return node of the system, which can better vent the whole system.
Visualize actions: The manual exhaust valve allows the operator to directly observe the exhaust situation, which is more intuitive.
The cost is relatively low: The cost of a manual exhaust valve is generally lower than that of an automatic exhaust device.
Cons:Manual work is required: Manual exhaust requires manual regular inspection and operation, and the labor intensity is relatively large.
The exhaust is not intelligent enough: Compared to automatic exhaust devices, manual exhaust valves lack automatic sensing and exhaust functions.
--Exhaust efficiency comparison
In terms of overall exhaust efficiency, the water separator can exhaust the system more comprehensively due to its location. In contrast, a small basket may require multiple combinations to achieve the same effect.
--Cost-benefit analysis
From a cost-effectiveness point of view, although the initial investment in a water separator is lower than that of a small back basket, a small back basket may save more labor maintenance costs in the long run due to its automated nature.
--System compatibility
For different underfloor heating systems, the choice of exhaust method will also be different. For example, in complex underfloor heating systems, automated exhaust with small back baskets may be more suitable;In a simple home floor heating system, manual exhaust of the water separator may be more economical and practical.
--Installation and maintenance
In terms of installation, the small back basket is relatively flexible due to its small size. Whereas, the separator is usually installed centrally as part of the system. In terms of maintenance, the automated nature of the small back basket reduces manual maintenance, while the water separator may require regular manual venting and inspection.
Summary:
Small back baskets and water separators have their own advantages and disadvantages, and the choice should be based on the size, complexity and maintenance cost of the underfloor heating system. For systems that require automated, efficient exhausting, a small back basket may be preferable;For situations where a budget is limited and the system is relatively simple, manual venting of the water separator may be more suitable. In general, ensuring that the underfloor heating system can operate stably and efficiently is the primary goal in the choice of exhaust method.
