Energy Efficient Hot Water Systems

Various options exist for installing a hot water system, including demand-type systems and tank-based units. Before deciding on the most suitable hot water system for your home, it is important to consider your energy usage and installation cost. Read on to learn more about Tank-based systems and the differences between a demand-type system and a heat pump. When looking for more storage space, consider installing a tandem tank.

The energy efficiency of hot water systems

In addition, the hot water tank should be insulated to prevent fires and conserve heat. If you have an electric storage hot water system, you can retrofit it with a heat pump. Unlike gas systems, heat pumps concentrate low-grade air-borne heat and dump it into a water storage tank. They also count as renewable systems for STC rebates. 

While electric water heating systems may use less energy than gas or electricity, the energy required by electricity is significantly lower, and this is due to the inefficiency of electricity generation and transmission lines. The majority of electricity in the US is only thirty to forty-five per cent efficient, which wastes a large amount of energy and creates harmful environmental consequences. Meanwhile, a gas pipeline delivers gas to homes. This means that gas and electric systems lose about five to ten per cent of their power.

Cost of installation

The cost of hot water system installation depends on the system installed. A basic electric system may cost around $700 to $1150. A gas hot water unit may cost around $1,250 to $3,500. Plumbers charge approximately $130 an hour. In addition to the cost of the hot water unit, plumbers also charge for pipes and fittings. If replacing an existing gas water heater, you should hire a plumber with experience installing gas hot water systems.

Tank-based vs. demand system

You might consider sticking with the traditional hot water tank system when on a budget. This system has stood the test of time, serving countless families without inconvenience. However, tankless systems may run out of hot water if your family uses several outlets at once. Consult a local plumber when unsure of the best option for your home. You may be surprised to discover that a tanked system is more affordable than a tankless one.

The tank-based system is an evolution of the pot on the stove. A fire heats the water in a storage tank and flows to any outlet. The setup of this system is fairly simple, as it relies on basic methods of heating water. Compared to a demand system, this system requires fewer materials and is more energy-efficient. For this reason, it is best to consider this system if you’re unsure which one is right for your home. For more information, visit

Solar vs. heat pump

Heat pumps can provide hot water and a lower cost of operation than solar energy systems. In some states, air source heat pumps can work in temperatures as low as -10 degrees. Despite their lower returns, many people will find this energy-efficient system worthwhile. The costs of heat pumps are currently quite high, but they are expected to decrease in the next few years as their reliability increases. Here are some important facts about heat pumps and solar power.

One major drawback of solar water heating is its potential to add load to the electrical grid. PV and heat pumps can use thermal energy from outdoor air, but they can’t provide hot water all the time. A heat pump will meet your hot water demand whenever you’re running a shower, while a solar collector will produce hot water only during the peak of the day. However, a heat pump can be installed on a roof and work in any climate.
