Marey Replacement for Bosch 125B, 1600P, 425PN, 520PN Tankless Water Heaters

The Marey GA16NGDP 16L natural gas tankless water heater is the closest possible replacement for Bosch's popular line of 125B-NG, 1600P-NG, 425PN-NG and 520PN-NG tankless water heaters.

Like these Bosch tankless water heaters, the Marey GA16NGDP tankless water heater has no electric requirement and uses 5" double-walled galvanized B-Vent for its exhaust venting. The Marey GA16NGDP is perfect for off-grid applications.

While the Bosch 125B-NG, 1600P-NG, 425PN-NG and 520PN-NG tankless water heaters all had a standing pilot light, the Marey natural gas 16L 4.3 GPM unit uses two D-Cell batteries for its ignition source.

And at 120,000 BTUs, the Marey GA16NGDP is very close to the 117,000 BTU maximum input of the Bosch 125B-NG, 1600P-NG, 425PN-NG and 520PN-NG water heaters.

Marey GA16NGDP 16L 4.3 GPM

If you are looking to replace your existing Bosch 125B-NG, 1600P-NG, 425PN-NG and 520PN-NG tankless water heater and your current unit is vented vertically through the roof then the Marey GA16NGDP will be a simple and straightforward replacement.

The Marey GA16NGDP natural gas tankless water heater can also be used to replace the Bosch natural gas tankless water heaters that used Bosch's patented Hydrogenerator as the ignition source. The Bosch 125HX-NG, 1600H-NG, 425HN-NG and 520HN-NG can all similarly be replaced by the Marey GA16NGDP TWH.

All of the aforementioned Bosch heaters were designed to vent vertically through the roof via a natural draft. They could also, however, be vented out the side wall with Bosch's AQ1 or AQ4 sidewall power vent kits. These sidewall power vent kits were specifically engineered to work with the Bosch heaters and will not work with the Marey GA16NGDP. If you are replacing a Bosch TWH vented horizontally with the Marey 16L natural gas GA16NGDP then you will have to remove the AQ1/AQ4.

It is always best to vent these non-electric tankless water heaters vertically, through the roof to get the best possible draft and performance from your heater.

The Marey GA16NGDP digital panel tankless water heater can also be used to replace the Bosch 125m000 BTU 125VP-NG unit as it also had no electric requirement and used 5" B-Vent.

The Marey GA16NGDP will work with lower water pressures than the Bosch tankless water heaters; the Marey GA16NGDP will run on a minimum 10PSI water pressure.

The Marey GA16NGDP can also be used to replace the Paloma PH12 legacy series tankless water heaters. The Paloma PH-12 series TWHs were 89,300 BTU units that used 5" B-Vent and ran on very low water pressure (as low as 2.1 PSI).

The Marey GA16LPDP liquid propane tankless water heater can similarly be used to replace the same Bosch and Paloma liquid propane (LP) versions of the same heaters listed above.

The Marey GA16NGDP and GA16LPDP 16L tankless water heaters are approved for installation throughout the US (including California) and Canada.

History of Marey Tankless Water Heaters

Marey was founded in 1955 by the visionary Puerto Rican entrepreneur Mariano Reyes (the company name derived from the joining of his first and last name), who devoted his entire life to the production of innovative tankless water heaters. Chasing his dream of sustainable, endless hot water, he developed the point of use shower water heater. Throughout his career, he contributed many new innovations to continue to progress the Marey brand and solidify Marey as a market leader in Puerto Rico. From the first shower heater product we have expanded our product lines to many different options to best suit any customer’s hot water solution needs. To this day, we continue the same passion which Mariano founded the business upon to provide the most reliable and efficient products at an affordable price for our customers.

Marey Power Gas GA16L Gas Tankless Discontinued

GlobalTowne would like to announce that Marey has recently stopped making the Marey Power Gas 16L gas tankless water heater.  The GA16L came in either NG or LP gas and was a one use at a time whole house gas tankless water heater.

Marey still continues to make the Power Gas 16LDP (Digital Panel) unit and also the Marey 16L ETL.  These units are great for small households that use 1 major application at a time.  These units require no power and operate off 2 D cell batteries which make them great for camps and cottages.
