Are condensing water heaters worth it?

Condensing water heaters are expensive but have lower operating costs, perform much better (up to 40%) than their standard counterparts, and are equipped with the most innovative features and technology – making them a good buy and long-term investment.

What is a condensing gas hot water heater?

Condensing gas water heaters. Like conventional heaters, condensing gas heaters have a tank. Instead of sending hot exhaust gases out the flue, which wastes energy, this heater blows them through a coil at the bottom of the tank. Incoming cold water flows around the coil and collects most of the heat.

How does a condensing hot water heater work?

In a condensing heater, a draft-inducing fan pushes air and fuel into a sealed combustion chamber inside the tank (see Figure 1). As the fuel burns, combustion gas is exhausted through a secondary heat exchanger — a coiled steel tube submerged inside the tank. All are far less expensive than stainless steel.)

What’s the difference between condensing and non-condensing water heater?

Condensing tankless heaters use a dual heat exchanger design to make maximum use of the energy delivered to the system. Non-condensing tankless water heaters utilize a single heat exchanger so they vent more heat in the exhaust gases.

What is the advantage of a condensing tankless water heater?

A condensing tankless water heater can recycle that extra heat. It only vents the vapor when it is no longer useful for the heating process, and is known as a closed system. The vapor from a condensing tankless water heater is much cooler. Therefore it doesn’t require the same expensive and elaborate venting material.

Is heat pump hot water cheaper than gas?

Thus, although the initial cost of a heat pump is higher than that of a gas hot water system, its lower running costs save the average homeowner up to $225/year and an average of $3,375 over its 15 year lifetime.

Can you vent a hot water heater with PVC?

PVC is fine. As Jason mentioned, plastic (PVC or ABS) is ok to use as a venting material on powervented hot water heaters. They work by sending a huge amount of air in with the flue gases that it decreases the temperature of the exhaust going through the vent enough that it will not comprimise the vent.

How do you vent a non condensing tankless water heater?

Tankless water heaters can be vented in two ways: power-vent or direct-vent. Power-vent units use indoor air for combustion and simply vent the exhaust to the outside. Direct-vent units pull in air from the outside, so they have two vents for intake and exhaust.

Does a condensing tankless water heater need a drain?

If you own a condensing tankless water heater, your installer should have included a drainage system to drain your water heater. Don’t worry, it’s not leaking, but rather undergoing a normal process called condensation, and Noritz makes the removal process easy with its condensing tankless models.
