The number of gallons the water heater can heat per hour is called the recovery rate. This is also a consideration in buying a water heater. If you have some people in your home who use hot water at the same time, a higher recovery will be beneficial. All The Same, if you have a more typical hot water use pattern, a lower recover rate can be chosen. Water heaters with lower capacities and lower recovery rates will be less expensive.  Water heaters come in a variety of dimensions. Every water heater is tagged with an energy efficiency rating. Determine the capacity, size, fuel source, and energy efficiency needed for your home.

• 5.0 out of 5 stars Gas replaces Electric, July 18, 2009

We replaced an old electric HW heater with gas just last week. Until we get a couple of utility bills I won’t know if this will be an economical swap or not. Our gas company (who also provides our electricity) has a rebate program for conversion to gas, so there was a few dollars off. This is my first gas HW heater, and my initial observations are that it’s noisey, or at least I never heard the previous electric unit when it was working and with gas you obviously have a combustion burner running at times. I’m told however that gas provides very quick recovery and that it should reduce my energy bill overall. Fit and finish of this model looks good. This unit is about 1 foot taller than its electric predecessor, and our pet cat no longer finds the top of this HW heater accomodating for sleeping, with its’ somewhat reduced diameter and a chimney smack dab in the middle of her favorite spot. She’s not happy, but so far we are.

Bosch ES series is a huge step forward in technical development but such a bad taste has been left by former products and Bosch technical support that few plumbers will recommend one regardless of what improvements are made today or tomorrow. This model still has the same potential for gas valve failure that goes back to their 250 SX series that if condensation or rain is not caught before it reaches the gas valve, the valve must be replaced and is nearly 3X the cost of their competitors. Performance is as stated but if your incoming water temperature is not 65 F then expect far less performance. Your homes gas piping and water piping must be taken into account before considering this and the cost of a single wall stainless steel vent system must be calculated into the total cost. Bosch also requires a propritory roof termination kit that if not installed, voids your warranty and this too adds to the total cost.

As a licensed plumber contractor in Ca and a former authorized service provider I had never in all the years of servicing Bosch, seen a correctly installed Bosch tankless. It really doesn’t take that much effort to read the instructions and follow them. Of all the various makes and models we have installed in nearly 30 years, I never once had a failure or problem due to my own installations. Bosch service calls sometimes totaled more than 35 per week on new installations alone by home owners, handymen and plumbers. If properly installed, they are perfectly good water heaters. Tthey do have the best and most robust heat exchangers of all brands, this particular models control board is the most advanced and user friendly of all but only to service providers. The only downside is the limited access to Bosch technical support too and if not installed to the letter, Bosch may and have voided warranties in the past. Due diligence goes a long ways and emotional reviews only blur accurate information for those seeking answers. Bosch is making the effort to improve product and service and I will give them that…
