3 Things to Know About Venting Tankless Water Heaters

Demand for tankless water heaters is increasing day by day as they are one of the most efficient water heating options available. They provide up to 50% reduction in energy cost, in addition, up to 61% reduction of greenhouse gas emission. However, in some cases, misconceptions about the venting needs of tankless water heaters might keep professionals from recommending them. Here are three things you should know about venting tankless heaters that will help you clear or find a solution to those misconceptions.

Combustion System in a Tankless Water Heater

You can vent a tankless water heater in two ways. The first way is by power venting it. In power venting units, indoor air is used in combustion, and vented air is simply exhausted outside through a pipe. These units require a large enough room or an open space to have adequate air for gas combustion. In contrast, direct venting units intake air and exhaust heat outside through a double vent system with each vent dedicated for exhaust and intake. Due to this, they can be placed in smaller places such as an attic, closet, or small mechanical rooms.

Direct venting through a single pipe

Some tankless water heater manufacturers are offering concentric venting technology. In this technology, exhaust and intake vents are combined in a single multi-layered pipe. The inner layer of the pipe contains hot exhaust air, and the outer layer of the pipe sucks fresh air for intake. Due to this, the installation requires only a single hole through the wall. In terms of safety, it’s a superb choice as the hot exhaust vent is inside the cool intake vent. This makes the main pipe cold enough to touch. Moreover, there is no chance of hot air leaking from the exhaust vent as it is carefully placed inside the intake vent.

No need of venting with outdoor tankless water heaters

In warmer cities like Delray Beach, Fl, you can ease a plumber’s work by installing tankless water heaters outdoor as they don’t require any additional venting. However, make sure to choose an expert plumber. Moreover, designed to withstand temperature below freezing points through self-warming capabilities, newer models can be installed at freezing temperature as far as they get a constant electric power supply. It is advisable for low climate countries with power outages to install their units inside.

Tankless water heaters are safe, better looking, compact, environment-friendly, energy-efficient, and less power-consuming.
