Advantages of Hot Water Systems

0 0

Hot water systems regulate the water’s quantity of heat through temperature and flow rate. They vary according to the electrical load and ambient temperature, allowing greater flexibility in matching electrical load to heating requirements. When there is high electrical demand, heat energy can be stored in hot water tanks and sent out during low demand. Systems with storage capability continuously follow the electrical load to level the system heat demand. Here are some advantages of hot water systems. Weigh the pros and cons of each before deciding on which system will meet your needs.

Heat exchangers

Both have a single tube and a shell, but different variations are available. For example, tubes can be straight or curved into the shape of a U, hence the name U-tube. Tubes may also be flexible to allow more airflow or heat transfer. Despite the different types, all exchangers are similar in operation, but their differences can make them ideal for different applications. 

The choice of the heat exchanger depends on several factors. First, the material used is crucial. The heat exchangers in hot water systems are made from various materials, such as copper, aluminium, stainless steel, ceramic, and polymer. Choosing the suitable material is also essential, as different types of material have different heat transfer coefficients. A vendor must know the fluid temperature and viscosity. Knowing the materials likely to foul the exchangers is essential for choosing the right one.

Storage capacity

The storage capacity of hot water systems is the maximum volume of water that a tank can hold. It is important to note that this capacity is not to be confused with the recovery capacity. Recovery capacity measures how much water a heat pump can raise in one hour. It is the amount of water a heater can raise per hour based on its efficiency and Btu input. The storage tank capacity will also depend on the size of the solar collector. For solar heating systems, the recovery capacity is measured in gallons of water per square foot of collector. However, two gallons per square foot is recommended in scorching climates.

Indirect-pressurised systems are packaged and come as a package. Thermal storage capacity and the number of heating elements are design options for these systems. Indirect-pressurised systems are primarily used for off-peak water heating and are typically designed to shift all water heating energy input into off-peak periods. Typically, they are available with simple controls. However, direct storage systems do not always offer the same operating cost savings.

Energy efficiency

One of the world’s most efficient hot water systems boils water while drawing the least amount of electricity from the plug. Some of the most efficient appliances are microwaves, which are about 50 per cent efficient. On the other hand, electric stovetops achieve about 70 per cent efficiency. The difference between the most efficient and least efficient systems lies in how well they store hot water. Generally, the more efficient appliances can save you money.

Electric water heating is more efficient than gas or solar systems, but its net efficiency is lower. It is because of inefficiencies in power plants and transmission lines. Electricity generation in the US is only 30 to 45 per cent efficient, resulting in a large amount of wasted energy and negative environmental consequences. The transmission process of gas and electricity also wastes approximately five to 10 per cent of the power produced. Moreover, it takes at least a decade to heat a gallon of water from gas.

Cost

The cost of a hot water system can vary greatly depending on its size and the number of people in the household. Some installations are more complex than others, requiring additional labour and equipment. Installation can also be tricky and may involve cranes or wall-mounting. You should check with your contractor about additional costs before deciding on the type of system to install. In many cases, the installation fee includes the disposal of the old system to a recycler.
