Due to the mechanism, your unit can save up energy up to 98%. User is no longer need to wait for their heated water for a long time.

Inner Re-circulation Arrangement

This particular feature is a built in one in the Advanced lineups. The official name from manufacturer is ComfortFlow. Because of this arrangement, your heat system is able to detect the water flow and prevent incoming water (which is in ambient temperature) to receive the heat. It means that your system does not heat a portion of water that is already tempered.

Durable (and Warranted) Stainless Steel Exchangers

Exchangers are important components in condensing unit. In most models, you will find that the exchangers are made of copper material. However, condensation formed by the system’s mechanism will corrode the copper material quickly. In all of its lineups, stainless steel material is used for the exchangers. It is longer lasting and also warranted for 15 years.

Installation Factors and Cost

When you are installing one of this brand’s hot water furnace models, the unit’s price is not the only expense that you have to prepare. You should also budget the installation cost which can skyrocket depending on certain factors. In common scenarios, the cost will range from $1,000 to staggering $4,500.

1. Licensed Plumber’s Labor Cost

You cannot avoid employing licensed plumber to do the installation job for one of its models. This is done to avoid potential hazards in the future such as carbon monoxide (CO) leakage in the plumbing system. If you are not working with a recognized professional, your warranty right will be revoked from day one as well. As expected, hiring licensed plumber is pretty expensive.

2. Upgrading System in the House

This particular factor is responsible for increasing the unit’s installation cost significantly. In order to accommodate your new water heating furnace, your house needs to meet the unit’s system requirements. The process might involve setting up a new gas line and increasing the capacity of your electrical service. If your house is old and has dated system, you will be better off adding no-tank unit during renovation.

3. Adjusting the Plumbing’s Routing

When installing a unit, you may also need to adjust the route of your plumbing system. It is done to create better configuration so that your heated water system will be able to operate more effectively and in efficient manner. This job is considered large jobs and you may need to pay more than $500 for it.

4. Supporting Materials

People often overlook this cost component simply because they do not think it is important enough. The plumber will only bring necessary tools to do his jobs while you are expected to prepare the materials needed for the job. It might be costly especially if your plumbing job also includes retrofitting.
