Bosch FW200 Phase-Out and Replaced with CRC200 with Outdoor Reset

Bosch Thermotechnology Corp. just announced changes in two controllers for the residential Greenstar boiler line.  The Bosch FW200 weather compensating controller will be phased out once inventory is depleted, currently expected at the end of 2019.  The Bosch CRC200 thermostat manufactured December 2019 and later will now have outdoor reset capability in addition to all its current features. To enable this functionality of the controller, an outdoor temperature sensor is required (sold separately).  All Greenstar wall boiler models that include a CRC200 in the package will also have the updated controller implemented in production starting in December 2019.

Replacing Older Bosch Tankless with The Bosch Therm 830ES

The Bosch Therm 830ES Non-Condensing tankless water heater is a top performance, gas tankless water heater from Bosch. This 199,000 BTU heater is designed for residential applications and can deliver hot water up to 140 degrees F with a 8.3 GPM flow rate at a 35 degree rise.  Not approved for space heating applications.

This Energy Star approved tankless water heater can produce enough hot water for 2 major applications in most homes.

The Bosch Therm 830ES heater features an electronic ignition system and can vent through either 3 inch or 4 inch diameter stainless steel vent pipe either through the side wall or up through the roof. A stainless steel concentric side-wall venting option (ESHCK-Full-Kit) is also available.

The Bosch 830ES heater comes with built-in Freeze Protection but it does not come with the 3/4" PRV and the External Water Filter.  The freeze prevention kit is designed to provide protection for the water heater down to approximately 5°F for short term conditions only. It will not protect the appliance in areas where the temperature is routinely expected to be below freezing.  The freeze prevention kit will not protect plumbing outside the appliance from freezing.

The Bosch Therm 830ES is a wholesale model heater and sold to licensed plumbers and contractors. The new Bosch Therm 830ES is a close replacement for older models such as the Bosch 250SX/250SXO,  635ES/635ESO and the 2400E.  Please be aware the 830ES is 7" taller, 2.375" wider and 2.75" deeper than the previous models. The Bosch 830ES is a direct replacement for the Bosch 2400ES.  For outdoor installations the Bosch 830ES would require the BTOK Outdoor Kit.

The Bosch Therm 830ES comes with a limited 15 year warranty on the heat exchanger and 5 years on all other parts.  Service and labor costs are not covered.

New Bosch Tronic 3000T ES Mini-Tank Water Heaters

Bosch has rebranded the Ariston Pro Ti line of electric mini-tank water heaters. They are now labeled as Bosch Tronic 3000T ES Electric Mini-tank Water Heaters.

The old Ariston Pro Ti models GL2.5Ti & GL2.5TiS are now the Bosch ES 2.5.
The old Ariston Pro Ti models GL4Ti & GL4TiS are now the Bosch ES 4 .
The old Ariston Pro Ti models GL8Ti & GL8TiS are now the Bosch ES 8.

The new Bosch ES2.5, ES4 and ES8 electric mini-tank water heaters are the same size as the mini-tanks that each replaces.  The replacement parts for the new Bosch ES2.5, ES4 and ES8 are different now and will not work for the older Ariston GL2.5Ti, GL4Ti or the GL8Ti.

*  Please note that the new Bosch ES4 is not a direct replacement for the retail model Ariston GL4 as the Bosch ES4 is 13 1/2" in depth and the retail Ariston GL4 is 12 1/4" deep.

The new Bosch ES2.5, ES4 and ES8 have many new improvements since they have been upgraded. The mini tanks have a new temperature adjustment knob on the front of the unit to raise and lower the temperature from 65 Deg F to 145 Deg F. On the older models you would have to remove the grey oval cover to access the temperature control knob.

The Bosch ES2.5, ES4 and ES8 models have a new improved thermostat that features a new sensing probe that is attached to the thermostat and inserts into the cavity of the new heating element so the heater can adjust temperatures quicker and maintain a more consistent heat.

The new model ES8 now has to be hard wired to a plug for 110V.  Global Protankless Supply carries 6' cords for the Bosch ES8 heater.
