Hot Water Systems are used to provide a constant supply of hot water in homes, commercial buildings, and industrial settings. They can be powered by gas, electricity, solar energy, or heat pumps. A hot water system is a vital part of your home or business, providing hot water for cooking, cleaning, bathing, and washing clothes. But did you know that it also impacts your safety, comfort, and environmental performance? There are recommended temperature settings for hot water systems that balance health and safety, energy efficiency, and personal comfort.
Hot water can be stored in tanks or delivered on demand through pipes that run throughout your building. The temperature of the water can be controlled in each area by installing different valves. For example, you can set the thermostat to a higher setting for kitchens and bathrooms, and lower temperatures for laundry rooms and bedrooms.
Choosing the right type of hot water system for your home or commercial facility depends on several factors, including available space, local climate, and availability of energy sources. Electricity-powered systems are available in both storage and instantaneous types, while the most sustainable choices are heat pump or solar systems. Solar systems require adequate north facing roof space and a suitable location to get maximum solar access. Heat pump systems use electricity generated from renewable resources (such as solar photovoltaics) or greenPower supplied by your energy retailer, so they are low in greenhouse gases.
Most new hot water systems are designed to be as environmentally efficient as possible. They have features such as automatic water heating cut-out switches to prevent excessive energy use, and insulation to minimise heat loss. But the condition of your old or existing hot water tank can have a big impact on how efficient your system is, so it’s important to look after it.
For example, if the water heater has a corroded or cracked tank, it will leak. A leaky tank isn’t just inconvenient – it can be dangerous. A leaking tank can cause fires, toxic fumes, and damage to property and the surrounding environment.
Hot water systems should be located away from combustible materials such as timber, flammable walls, and flammable floor coverings. They should also be installed away from appliances such as gas stoves and ovens, and electrical outlets.
A good way to ensure that your hot water system is operating efficiently is to install a thermometer in the supply line between the tank and your load (e.g., your home’s hot water taps). A drop in the temperature of the water over an hour indicates that the tank is not storing enough energy, or that it is being topped up too often with extra fuel (e.g., a kettle being regularly used).
If your water heater is unable to keep up with the hot water demands of your household, consider upgrading to an instantaneous gas system or installing a heat pump or solar hot water system. These options will reduce your energy bills and greenhouse gas emissions while improving the quality of your hot water.
