To answer that, we created a list of Bosch tankless water heater reviews for 5 of what we think are the best Bosch tankless heaters. This should give you an idea of which products you can choose from.
Quick Buying Guide
Contents
Before we move on to the comparison table and the Bosch tankless water heater reviews, we think it’s best to start first with a short buying guide. This will help you further narrow down your choices, so you can choose the one most suitable for you.
Here’s the criteria you can follow:
BTU
The first thing that you need to take into consideration would be the BTU or the British Thermal Unit. For those who don’t know what this is, it’s basically the measurement of how much heat is emitted. For most good Bosch tankless water heaters, you can get a BTU of 31,000 to up to 190,000 BTU depending on how heavy-duty your unit is.
Gas or Electric Water Heaters
Bosch provides both gas and electric water heaters to customers depending on their own preference. Therefore, what exactly is the difference between the two anyway? Well, electric water heaters are more expensive in the long run since they use up a lot of power to work. Gas ones are cheaper in the long run, but they have a higher upfront cost since you need venting installations and connection to gas lines. Of course, your choice will depend on which one suits you the best.
Flow Rate
Lastly, you need to consider the flow rate of your unit. The flow rate would actually determine how much water your unit can heat up. The usual flow rate of a residential unit is around 1 GPM. The higher the flow rate the better, but we recommend you get one that just caters to how much you would use it. For average families, 1 GPM is already enough.
Safety Features
Lastly, we also need to watch out for safety features. Some safety features you’ll want to check out are those temperature consistency sensors and overheat protection systems so that your machine won’t get too hot.
And now that you know more about the features to look for in this type of product, we can move on to the Bosch tankless water heater reviews.
