Marey GA5F & GA10F Tankless Water Heaters

 Globakltowne would like to announce we are now carrying the new Marey GA5F & Marey GA10F tankless water heaters.  These units come set for either Natural Gas (NG) or Liquid Propane (LP).  The Marey GA5F & GA10F are small gas tankless water heaters for small low flow applications and good for camps and cottages.  These units require no electrical power and ignite using 2 D-Cell batteries.  

The previous Marey GA models were activated by a water valve that contains a diaphragm that activates the unit through pressure, and the new Marey GAF models are activated with less pressure because it contains an impeller that turns and activates the unit when sensing water flow.  the new Marey GAF models contain 2 solenoids, the previous Marey GA models contained only one, it means that if the batteries of the new GAF models are bad they will not activate the unit due to lack of voltage, and the improvement in the units is that they activate with less water pressure than the previous one.  Please see more specifications listed below:

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.

Marey Power Gas GA5L/10L/16L Tankless Water Heaters at Elevation

The Marey Power Gas naturally drafting gas tankless water heaters model GA5L/GA10L/GA16L are good for up to 6,000 ft elevation.  There are many people running the units at even higher elevations and the units will still operate well.  The air and gas mix at higher elevations will cause sooting in the heater exchanger and flue exhaust so this wants to be checked periodically.  You have to be aware that you will also loose 4% of your heat rise for every 1,000 ft above sea level...  this is applicable to all gas appliances.

The Marey ECO085 is a 8.5KW point of use electric tankless water heater.  It is recommended that you have at least a 150 amp electrical service to your home before installing the Marey ECO 085. The Marey ECO085 gets hard wired in using 8 gauge wire to a 40 amp breaker.

Marey heating elements are made from a single piece of cast aluminum, so there will never be water leakage non electric leakage in the heating chamber. Marey heaters also have an extra stainless steel water flow channel instead of the previous layered plate style, so no matter how your water quality is inside the heating element, it will provide a long life of service.  The compact and powerful Marey electric tankless water heaters are CE and ETL Approved and designed with German Technology.

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.

Determining The Proper Tankless Water Heater

The Marey tankless water heaters come in many different shapes and sizes and there is not really one that fits all needs.  Determining the proper water heater to fit your application should be based on the number of fixtures that are to be used simultaneously, and their accompanying flow rates. Every home and every end user is different, so the sizing of the tankless water heater should be calculated to fit the needs and each home and user.  Many end users have homes with low flow water fixtures and they are cautious of the water they use while others have high flow fixtures and use many applications at one time.  What this really comes down to is the end users preference and their demands.  The Marey tankless water heaters come in either gas or electric so you will need to determine which will be best for you and is most cost efficient.

Step 1:  List your fixtures
Go around your home and add up the total number of water fixtures that use hot water.  These will be shower heads, bathroom sinks, kitchen sinks, etc.  Do not forget to add in washing machines and any other fixture that uses hot water.

Step 2:  Choose your simultaneous needs
Now it's time to figure out which of these fixtures/machinery will need hot water at the same time. Try to keep in mind the more simultaneous water fixtures you need.

Step 3:  Calculate Gallons Per Minute (GPM) for selected fixtures
GPM is the standard flow rate in the US and most of your faucets and showerheads will have their GPM flow rate stamped into the side of the fixture.  If the flow rate is not listed then you can use a gallon jug and time the flow of the water into the jug and this will give you the GPM for that fixture. After you have your flow rates of each fixture you will need to supply hot water to you can add them up and this will help determine which tankless water heater is good for you.  Please see the chart below for a better understanding of determining your flow rates.

Venting Your Marey Gas Tankless Water Heater

Marey is always updating and trying to improve on their manuals and installation guides.  Marey will soon be updating their installation manuals for the gas tankless water heaters.  Please follow the installation manual when installing a Marey tankless water heater.  You will also want to check local code as all local codes sometimes supersede the manufacturers recommendations. Below is a list of the venting required for the Marey gas tankless water heaters.

Venting Requirements
Marey GA16NGETL Power Gas 16L ETL - unit requires 3" stainless steel single wall sealed venting. This unit can be vented either vertically up through the roof or horizontally out the sidewall of the building.  Please click on this link for 3" stainless steel venting and vent kits:  3" Stainless Steel Venting
