Bosch Aquastar Tankless Water Heater 2700ES

Filed Under Bosch

The Bosch Aquastar tankless water heater 2700ES is a large model, allowing your family to be taking three showers at once, or perhaps more likely to be taking two showers while doing a load of laundry or dishes. It is larger than most families will actually need, as two activities at a time in a whole-house system will be adequate for most medium-sized families. Note that in very cold climates, where tankless water heaters have colder water coming into them, this unit might only do two activites at a time to your satisfaction.

Think it's a monster unit? It is in terms of capacity. You are most unlikely to ever run out of hot water, even in those colder climates. But in terms of size, like all tankless water heaters, it's really quite small and hangs on a wall in your house with various ways of achieving direct venting. It has a built-in power vent for this purpose.

Be sure that the unit is properly installed -- that meaning reading the manual and ideally having someone install it who has had experience with tankless water heaters. If not properly installed, it may not work right.

There are also outdoor installation kits available, in warmer climates only. Other bells and whistles include electronic ignition, and an optional remote thermostat.It is available for both natural gas (NG) and propane (LP).

The ES at the end of 2700ES means that it is listed as an "Energy Star" model by the US government ranking system developed by the Department of Energy. You can get a US tax credit of up to 30% of the price of this unit AND the cost of installing it.
