Marey GA16LPDP and GA16NGDP Units Discontinued

Marey has discontinued manufacturing their popular 16 liter tankless water heaters -- the GA16LPDP and GA16NGDP.

Marey 16L Tankless Water Heater

These 120,000 BTU tankless water heaters required a 5" B-Vent exhaust stack run vertically up through the roof. These "off-grid" water heaters use two D-cell batteries as their ignition source and do not have electric hookups.

The liquid propane GA16LPDP unit was the closest available replacement for the 117,000 BTU Bosch 125B-LP, 125HX-LP, 1600P-LP, 1600H-LP, 425PN-L, 425HN-L, 520PN-LP and 520HN-LP propane tankless water heaters.

The natural gas GA16NGDP unit was the closest available replacement for the 117,000 BTU Bosch 125B-NG, 125HX-NG, 1600P-NG, 1600H-NG, 425PN-N, 425HN-N, 520PN-NG and 520HN-NG natural gas tankless water heaters.

GlobalTowne still has a limited supply of new Marey GA16LPDP and GA16NGDP units available for sale. Available only while supply lasts.

Marey Replacement for Bosch 80VP, Bosch 38B and Bosch 330PN

The Marey Power Gas GA10 or GA10DP 10L tankless water heater is the closest possible replacement for Bosch's popular line of 80VP, 38B or the 330PN tankless water heaters.  These units come in either Natural Gas (NG) or Liquid Propane (LP).  The only difference of the Marey GA10 and the GA10DP is that the GA10DP has a small digital panel on the front that shows the temperature when the heater is in use.

Like these Bosch tankless water heaters, the Marey GA10 or GA10DP tankless water heater has no electric requirement and uses 4" double-walled galvanized B-Vent for its exhaust venting. The Marey GA10 or GA10DP is perfect for off-grid applications.

While the Bosch 80VP, 38B and 330PN tankless water heaters all had a standing pilot light, the Marey 10L 2.6 GPM unit uses two D-Cell batteries for its ignition source.

At 79,000 BTUs, the Marey GA10 or GA10DP is very close to the 78,000 BTU maximum input of the Bosch 80VP, 38B and 330PN water heaters.

Marey GA10 or GA10DP 10L 2.6 GPM Tankless Water Heater
If you are looking to replace your existing Bosch 80VP, 38B or 330PN tankless water heater and your current unit is vented vertically through the roof then the Marey GA10 or GA10DP will be a simple and straightforward replacement.

The Marey Power Gas GA10 or GA10DP must be vented vertically with 4" galvanized B vent and there is no sidewall power vent for these units.

The Marey GA10 or GA10DP will work with lower water pressures than the Bosch tankless water heaters; the Marey GA10 or GA10DP will run on a minimum of 10 PSI water pressure.

The Marey GA10 and GA10DP 10L tankless water heaters are approved for installation throughout the US (including California) and Canada.

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.
