If you've converted your basement into a spare bedroom with a bath or put an apartment in your garage, you'll need a way to get hot water for the faucets and shower. Your current hot water heater may not be large enough for the added demand. Your choices would be to get a larger tank heater, switch to a tankless heater, or add a tankless heater to the plumbing for the new addition. Adding a new tankless water heater might be the best choice. Here's an overview of the steps involved in tankless water heater installation services.

Learn About The Permits You Need

You'll probably need to get permits for installing a new tankless water heater. If you're not removing your old heater, then you may need new gas lines and an electrical outlet near the heater. These steps could also involve visits from the codes inspector to make sure the work is done according to building codes. Your plumber will explain the process of getting permits and inspections, and he or she may even handle most of the work and scheduling for you.

Decide Where To Put The Heater

A tankless water heater is small enough that it can fit in a fairly small indoor space, such as a closet, as long as it can vent to the outside. However, proximity to plumbing pipes is an important consideration because being close to water and gas lines makes installation less costly. You may have no idea where the lines are if they're hidden behind a wall or under the floor. You may want to work with the plumber to locate the pipes and then decide on the best location for the heater.

Prepare For Installation

Long before installation day arrives, you'll need to decide on the size of the heater and if you'll power it with gas or electricity. Getting the right size is important so you'll be happy with the way the heater performs. A plumber will calculate the best size based on how you plan to use the heater. While a gas heater might be less expensive to operate daily, there will be an initial expense of installing gas lines if you don't have them already. Be sure you factor in all the costs associated with installing a tankless water heater for the first time when you don't have existing connections.

Install The Tankless Heater

Tankless water heater installation involves mounting the unit on the wall and running a vent to the outside. Then, the plumbing lines are attached, as well as gas lines if you'll power the unit with gas. If you use electricity to power the water heater, you may need to have a new outlet and circuit put in, so talk to your plumber about the need to bring in an electrician to assess your electrical panel and put in a new outlet if it's needed.

Once the planning is out of the way, the actual installation of the hot water heater goes fairly quickly. The installation will probably be completed the same day as long as no complications arise.
