Tankless Water Heaters
A tankless water heater is an in-demand machine. That means it provides water only when it is needed. No storage tank holds hot water. These units can be highly efficient, because they do not require the insulation and constant heat of a traditional water heater. At Wilson Plumbing & Heating, Inc., we can help you decide if a tankless water heater is a good option for you and your family.
The positives about a tankless water heater
A tankless water heater has many positives to consider.
They can save you a bundle on energy costs, because they run so efficiently. They are a good choice for a household that uses less than 42 gallons of hot water per day, because they will provide a 24 to 34 percent energy savings. For households with high hot water usage of 86 or more daily gallons, they can be 8 to 14 percent more efficient. For maximum efficiency, you can designate a separate unit for each water source. This will provide energy savings between 27 and 50 percent.
You have instant access to hot water. Simply turn on the tap and the hot water is ready.
Good supplement system
You can supplement a traditional system with a tankless system if you need extra hot water for an appliance that runs often. For example, if you do a lot of laundry, you can install a tankless system just for the washing machine. That way, it won’t affect the hot water supply when showering or washing dishes. They can also be used as a backup for a solar-heated system.
Because there are fewer parts to maintain, these units have a longer life than traditional models, which saves money on replacement costs. You can anticipate a tankless model to last 20 years, as opposed to 10 to 15 years for a traditional model. They typically come with longer warranties, too.
Tankless models are wall-mounted and typically require far less space than other models. This can make them ideal for small spaces or historic homes. They can free up storage space in a closet or pantry.
Their high efficiency leaves a smaller carbon footprint. Also, they won’t junk up the environment with a rusty tank when they expire, like a traditional model.
The downside to a tankless water heater
We’re not going to fool you—there are some negatives to consider.
Slower flow rate
Their flow rate can be slower because their output is smaller than a traditional water heater.
Higher initial cost
Even though you will save in the long run, you can expect to pay more up front for a tankless model. Some models cost up to three times more than traditional units.
Gas-fired models may cost more to operate
If the pilot light burns constantly, the energy savings will decrease, and may cost you more than you expected. Ask us about the best option for pilot light models and about intermittent ignition device models.
Need high electric capacity
Tankless water heaters fueled by electricity will require up-to-date electric utilities. If your electrical system needs an overhaul, the costs may be prohibitive.
Higher installation costs
Since tankless models have special venting requirements, the installation cost can be slightly higher than it is for other units.
