Pros and Cons of Tankless Water Heaters

Tankless water heaters are touted as ‘unlimmited hot water’, ‘eco friendly’ and ‘energy saving’, but with their high upfront cost, most consumers should familiarize themselves with the technology before going out and buying one. Tankless water heaters have a number of pros and cons, and you should know about them before you buy.

Cons of Tankless Water Heaters

More Expensive Upfront

Tankless water heaters typically run from $500-$1500, and the inexpensive models are typically small. Storage models are very expensive, and most of the time you will spend about twice what you would on a regular water heater.

More Maintenance Required

Tankless water heaters also typically require more care and maintenance. Because they flash boil water, they are more vulnerable to calcium buildup and lime. Most of the time you will probably have to pay for a checkup at least once a year, and flushing the whole system can be expensive if a clog develops.
Hot Water Issues
Probably the worst issue with tankless water heaters is inconcsistency. While you do get unlimmited amounts of hot water from your tank, the system might not be as consistent as you might like. For example, it might not even turn on for the small amount of water you need to wash your hands, unless you turn the sink on all the way. You’ll also get ocassional bits of cold water between hot water, as it uses the cold water that was in the lines.

Hidden Costs

Installing a tankless water heater isn’t just putting it in and connecting it to the water supply. You might have to purchase additional pipes, create vents for the fan, and sometimes even gas pipes, which can skyrocket the cost of installation.

Pros of Tankless Water Heaters

Endless Hot Water

If you have a large family or have previously had a small tank heater then you know that it sucks to run out of hot water. That won’t happen with a tankless water heater. Tankless water heaters heat water on an on-demand system, flash boiling it as you need it. This is the same process used by on-demand and 3-minute coffee pots.

Eco-Friendly

Tankless water heaters are also eco-friendly. Rather than continuously keeping a large tank of water warm, they only kick on when you need it. If you don’t use a lot of hot water throutout the day, then you can definitely see how this might save you money. Most manufacturers suggest that their tankless systems use 40% less energy then a tank heater. Depending on whether you preivously used gas or electricity, and how large your tank was, you could save a great deal on energy costs as well.

Tax Rebates

You can also get a tax rebate in most states for purchasing a tankless water heater.

Small Design

Most tankless water heaters are about the size of a small suitcase, meaning that you can put them almost anywhere. In fact, you might even be able to clear out whatever space your old hot water heater was in and put a cabinet in.

Custom Design

Tankless hot water heaters are available in multiple sizes so that you can choose one for your needs. Like tank heaters, you can pick a heater that is likely to be able to easily heat the amount of water that you need.

Should You Buy One?

If you’re accustomed to having hot water without all of the quirks of a tankless heater, you may be relunctant to switch. In fact, you don’t necessarily have to.  A home with heavy hot water usage might save between $80-$200 a year depending on the cost of gas in their area, which essentially means that it can take more than ten years to cover the cost of the heater. When combined with expensive maintenance, the truth is that most tankless hot water heaters are not as economical as they might seem. However, they are eco-friendly, do provide unlimmited hot water, and can be very convenient for large families and houses.
