Tankless Water Heater Guide (Which Type Should I Get?)

The tankless water heaters can mainly be divided into three categories.

1. Non-condensing

These belong to the category of the earliest tankless water heaters. These heaters use highly reliable technologies and rarely have manufacturing issues. However, the disadvantage is that they have two hot exhausts that require the installation of expensive steel venting. They are also not as energy efficient as their counterparts. Furthermore, the efficiency of these heaters gets reduced when you use them on a frequent basis.

2. Condensing

The main difference between the non-condensing and the condensing tankless water heater is that the latter has a second heat exchanger installed in them. This means that the heat that would have otherwise gone thrown out of the exhaust will be used to heat the water further. This reduces the cost of operation and does not reduce its efficiency when used continuously for short draws.

3. Condensing hybrid

The unique feature of these heaters is that they feature a holding tank which acts as a hot water reservoir. This helps in increasing the efficiency of the heater when used for short draws. It also eliminates the issues that normally arise with pressure fluctuations. These are much more reliable as compared to the condensing and noncondensing tankless water heaters.
