Many homeowners wonder whether their homes would benefit more from traditional water heaters or tankless versions. The truth is that both types work better in certain settings. Speaking with a trained plumber is the best way to determine which type will work better for your home.
Hot Water Supply Method
Most conventional water heaters include a storage tank that can hold anywhere from 20 to 80 gallons of hot water. This heated water is ready to go whenever you need it, but it can run out quickly if used excessively. Tankless water heaters do not retain hot water. Instead, they heat it on demand. Tankless types are perfect for big families. They also work well for homes that utilize numerous hot water sources at once since there is an infinite supply of hot water.
Energy Efficiency
When picking out a water heater, efficiency – in terms of energy use – should be your top priority. The standby heat loss that occurs when conventional water heaters hold the water at a constant temperature is a major source of energy waste. The United States Department of Energy reports that this is a major contributor to rising energy costs. In contrast, tankless water heaters reduce energy use and utility bills. Homes that use less than 41 gallons of hot water per day can be 24–34% more energy efficient than conventional ones.
Size and Space Requirements
Because of their size and footprint, traditional water heaters aren’t always the best choice for urban dwellings. They often occupy a large section of a basement or utility room due to their specific installation requirements. Alternatively, you can save floor space by installing a tankless water heater, which is small and wall-mounted. Their small size makes them a great choice for houses with minimal square footage.
Initial Installation Cost
The price of a tankless heater usually varies from $1,000 to $3,000, whereas that of a traditional unit might be anywhere from $300 to $1,500. You must, however, account for any additional required installation expenses. Prices may differ according to the going rate for local personnel and any required adjustments to the electrical or plumbing systems. Tankless water heaters may not be the most budget-friendly option at first. However, their extended lifespan and potential energy savings might end up saving you money.
Operating Costs
It’s very important to consider the differences in operating costs when comparing water heaters. Traditional heaters incur ongoing costs due to the need to maintain a consistent temperature for the stored water. A rise in monthly energy expenses might occur if there is a considerable variance in hot water demand. The on-demand performance of a tankless water heater often results in reduced monthly expenses.
Lifespan
Most traditional water heaters last anywhere from 10 to 15 years with regular maintenance. Tankless models, however, can last upward of 20 years with proper care. A longer-lasting water heater means you won’t have to spend as much on replacements, which can save thousands of dollars. This means a tankless version could be the smartest financial choice for your home.
Maintenance Requirements
Both conventional and tankless water heaters need maintenance, but the specifics can vary. Flushing the tank regularly is a common practice for traditional units to eliminate silt accumulation. It is also important to check the anode rods and replace them at regular intervals to keep them from rusting. Descaling tankless water heaters is necessary on an annual or biannual basis to eliminate mineral deposits from the heating components. While both types of water heaters require maintenance, the descaling process for tankless systems may necessitate a slightly higher level of effort.
Recovery Rate
What we mean by “recovery rate” is the speed with which a water heater can reheat water after its reservoir is empty. A conventional water heater’s recovery rate is the number of gallons of water it can heat up in one hour. The tank’s capacity and power supply determine this pace. Tankless water heaters, on the other hand, do not have a recovery rate in the conventional sense since they continually provide hot water. This continuous flow is especially helpful in households with several appliances that need hot water at once, such as dishwashers, washing machines and showers.
Environmental Impact
Because of standby heat loss, traditional water heaters use more energy and produce more greenhouse gas emissions during their lifetime. Tankless water heaters are better for the environment since they consume less energy and heat water on demand. This means that switching to a tankless version is a great way to lend a friendly hand to Mother Nature. You might find this extremely helpful if you’re trying to go green.
Water Heating Speed
Conventional models may be slow to heat up, particularly when the water tank is low. During times of high demand, this wait can be quite annoying. Tankless water heaters heat water as it runs through the device, so there’s never a shortage of hot water.
Ventilation Needs
Venting is usually necessary for conventional gas water heaters to release the combustion gases, which may add space and expense to the installation process. Though all gas versions need ventilation, tankless ones may use a venting system with a smaller diameter; this allows for greater installation flexibility. Installing an electric tankless water heater is a breeze since they don’t need any venting.
Noise Levels
Concerns about noise levels are common among homeowners, particularly in homes with open floor designs. Because traditional water heaters don’t cycle as often, they tend to be quieter. Nevertheless, they have the potential to make a racket when the burner starts up or when the heat cycles. Tankless water heaters sometimes make a buzzing sound when turned on. Though the buzzing isn’t usually very loud, it could be quite noticeable in a peaceful setting.
Water Quality and Mineral Buildup
Water quality and mineral accumulation stand out as major variables impacting performance and lifespan when comparing tankless water heaters to normal ones. Traditional water heaters, which use a tank to hold heated water, may eventually get clogged with silt. When minerals from hard water settle to the tank bottom, they may cause corrosion and rust, which worsens the water quality. Sediment accumulation may also lower efficiency since the heater needs to work more to heat water that already contains sediment.
There is less chance of sediment accumulation with tankless water heaters since they heat water on demand rather than storing it. Nonetheless, mineral deposits may still affect them, particularly in regions with hard water. Proper descaling regularly is essential for keeping water quality and performance at their best.
Getting an Expert’s Opinion
Our plumbers can evaluate your home’s hot water use, especially during peak demand, before recommending a conventional or tankless water heater. They will also measure the available space and the current plumbing system. Other pertinent factors to consider include the homeowner’s budget, the water quality in the area and the unit’s energy efficiency ratings. Many experts will give you a cost-benefit analysis that breaks down each option’s potential savings and maintenance requirements.
