The Bosch Therm 330 PN LP is powered by a cheaper energy source which is propane. Unlike other models which requires electric ignition, this water heater doesn't.
Although you can expect great performance, this unit is not as efficient as its close competitors which has .82 Energy Factor compared to its .68. Compared to Eccotemp FVI-12-LP which has almost the same features and has 4 GPM flow rate, Bosch Therm 330 PN LP only delivers 3.3 gallons per minute.
When it comes to water heaters, it is all about the performance versus the price, with the ease of installation factored in their somewhere. So, when you have a unit that is cheap but it doesn’t run very well, give you very much in the way of energy savings and isn’t reliable, it isn’t worth paying a lower price. That’s where this Bosch Therm 330 PN LP unit comes in. While the specifications listed on the box are good specs and the price is fair for those specifications, there have been few unsatisfied customers who haven’t had much success with this unit. So, in the way of performance, it doesn’t work reliably.
This unit has a Piezo push button ignition and there is a gas valve that keeps the temperature the same even when flow rates are higher or lower. It weighs under 25 pounds and it is about the size of a large suitcase. California residents should view Proposition 65 before buying. It has a 3.3 gallons per minute flow rate and 75,000 BTU.
Some of the information that you might want to know that isn’t listed in the product information include the fact that you’ll have to clean it about once a year, but the instructions are included and it is fairly straightforward. Also, you need to have a minimum of 30 PSI if you want to operate this water heater. The push button pilot ignition can only have to start at the beginning, or if it goes out for some reason, and remember, you can probably only use one of your faucets at a time with this unit because it just can’t keep up with any more than that.

Reliability and Warranty
This unit has a few problems as a quick read-through of the reviews will tell you, but it is for the most part, a solid, reliable water heater. However, for the price that is listed, you could get a better unit, or pay less for the same water heater. As far as the warranty goes, it has a 3 year warranty on parts and then up to 15 years on heat exchanger.
You can probably find a better choice for water heaters. If you are particularly fond of this brand then this might be the water heater for you, but if you aren’t too worried about the name, only the performance and reliability, you are probably going to be happier with another brand, or at least a different Bosch model.
