Water Heater System GuideEccotemp and Marey both appear in this source set through tankless water-heater facts, but this page is not a controlled head-to-head, and an apples-to-apples spec match was not verified. Eccotemp's copied facts come from Eccotemp's cited record. Marey's copied positioning fact comes from Marey's site, while the detailed Marey ECO model facts are retailer-sourced as stated in the copied facts. This page does not declare a winner.
A note on how to read this comparison
The cited facts do not test Eccotemp and Marey units under the same household, installation, water temperature, fuel, electrical, or use-case assumptions. Eccotemp's record includes positioning, product-line scope, and selected model examples from its cited record. Marey's record separates manufacturer positioning from retailer-listed model details. Those source boundaries matter.
A fair quote review should keep each claim attached to the source that makes it. Eccotemp's cited model examples are SH22 and L5. Marey's cited model examples are ECO110 and ECO150, with the copied facts explicitly marked as retailer-sourced. If a quote uses a different model or adds warranty, installed cost, or sizing claims, those claims need their own supporting documentation.
Eccotemp published specs
Eccotemp's cited record positions the brand around budget smart eco-friendly tankless products, markets it as #1 Portable Tankless Water Heater, and describes indoor and outdoor residential and commercial scope. The same cited record lists product categories: portable tankless, gas tankless using propane or natural gas, electric tankless, SmartHome products with Alexa and Google, and electric mini-tank.
The cited SH22 model evidence lists 6.8 GPM, gas operation, and smart app integration. The cited L5 portable evidence lists 1.5 GPM and propane or natural gas operation. Those are narrow model facts. They should not be stretched into claims about every Eccotemp product category.
For quote review, the key question is whether the seller or installer names the exact Eccotemp product and matches it to the right category, fuel or power source, placement, controls, and any missing warranty or installation documentation.
Marey published and retailer-listed specs
Marey's cited manufacturer positioning describes it as a tankless water-heater specialist serving the continental US and Puerto Rico, with electric and gas lines. That is brand-level context, not a model-level performance claim.
The detailed model facts in this copied source set are retailer-sourced. The ECO110 fact lists 11 kW, 3.0 GPM, 220-240V, electric, self-modulating operation, and a 60A double-pole breaker, with Lowe's named in the copied fact. The ECO150 fact lists 14.6 kW, 3.5 GPM, 220V, self-modulating operation, multiple points of use, and electric operation, with Home Depot named in the copied fact.
Those Marey facts should be used with the source type intact. A quote should confirm the exact model, seller documentation, electrical requirements, flow value, warranty terms, and installation scope before the buyer compares it with an Eccotemp product.
How to actually choose
Use this page as a source-bound checklist. Eccotemp's cited record supports questions about product category, SH22, L5, fuel or power source, smart app integration, and portable use. Marey's cited record supports questions about tankless brand positioning and retailer-listed ECO110 and ECO150 electrical and flow details.
The comparison should not produce a brand winner. It should push the quote into specifics: exact model, intended use, fuel or electrical setup, placement, flow basis, control features, warranty terms, and installation scope. If a claim is not present in the cited record or supplied by the seller or installer, keep it out of the decision.
