How Much Does it Cost to Install a Tankless Gas Water Heater?

The typical price for tankless gas water heater installation is $540 – $2,750, not including potential permitting fees. This accounts for both the price of the tankless water heater itself and the costs of labor involved. It’s important to keep in mind this estimate does not include additional add ons such as heat pumps/pipes and gas line installation/replacement. 

The main fees aside, there are a couple of other things to consider when preparing to have a tankless gas water heater installed. You may have to have previous work done to make room for the new water heater; this will require you to hire a carpenter or handyman. Drywall may need to be removed, as an example. Considering this it’s recommended that you get a personal quote for the remainder of the project.

Does A Tankless Water Heater Have A Downside?

Yes, just like many things tankless water heaters have a downside.The main downside of a tankless water heater is that you’ll have to deal with the price. While there are different sized units that will vary in cost, depending on your situation the price may skyrocket quickly. Tankless water heaters are comparably more expensive than your normal water heater.

Firstly, it’s important to keep in mind that tankless water heaters have high-powered burners. Considering this, if you do not have an adequate ventilation system in place you will have to pay to have one installed before putting the water heater in. This is one of the few reasons that tankless water heaters are so costly. 

 If you live alone you may be able to get away with a smaller unit, but if you have housemates or a midsized family it’s suggested that you bite the bullet and invest in a larger sized water heater. This is because smaller units service one water outlet at a time, so if for example if someone is showering and another person is washing the dishes, it will not run hot water as desired. As an added note, it’s important when considering a tankless water heater that you research which type would be the best fit for your home. Tankless water heaters come in two versions: electric and gas. Below we will go over some pros and cons of each kind. 

1. Gas Tankless Water Heaters: On the plus side, gas tankless water heaters last considerably longer than your typical water heater, and they are a lot safer to have in the home. On the downside, if there is too much scale buildup, the water heater may suddenly shut off. (For context, scale buildup is the accumulation of minerals in water typically made up of calcium and magnesium. These can be difficult to dissolve, and so can cause a real problem for you if your water heater is damaged by it.)

1. Electric Tankless Water Heaters: The electric model is more efficient and sleek than it’s gas counterpart, but there is one huge downside with it. Electric water heaters take up a lot of energy. Think, 20,000 watts of electricity to the usual 5,000 a water heater would ordinarily pull. It goes without saying this may have some drastic effects on your electric bill.
