Are tankless water heaters difficult to install?
Not at all. Any plumber and electrician that have experience installing traditional water heaters will have no problems installing a tankless water heater. In most cases, they will only cost slightly more to install than a traditional tank. Please review the installation information for the relevant model(s) you are considering prior to ordering as it is important to ensure that your home has the necessary electrical capacity or that it can be installed at a reasonable cost.
