Gasland CE528LP
Amazon customer rating as of
Tankless Geek editorial score: 4/5
The Gasland CE528LP (Gasmart E) is a budget indoor whole-house propane tankless: 150,000 BTU/h, up to 5.8 GPM, with an oxygen-free copper heat exchanger, tempered-glass front, and freeze protection that kicks in at 41 °F. It's compact and wall-mountable — about 24.7 × 14.25 inches and 38.6 pounds — so it tucks into a closet or laundry room, and it's CSA certified for residential indoor use.
One number deserves a caveat: Gasland advertises "96.9% efficiency," but that's a combustion/thermal figure, not the Uniform Energy Factor used to compare real-world running costs. As a non-condensing unit its honest UEF is around 0.80 — good, but not the near-condensing efficiency the headline implies, and it still needs proper venting (no condensate drain). The unit is well-liked so far, but its review base is small, and the warranty is a first-year replacement rather than a long heat-exchanger term. For a buyer who wants whole-house propane flow at a low price and accepts a budget brand's shorter track record, it's a lot of capacity for the money.

Best Use Cases
Our Verdict
A low-cost indoor whole-house propane unit with genuine 5.8 GPM capacity and a compact footprint. Just read the efficiency honestly — it's a ~0.80 UEF non-condensing heater, not the ~97% the marketing suggests — and weigh the short warranty and thin review history. A sensible budget pick for a mid-size home that values price over pedigree.

How much hot water you'll actually get
Usable flow drops as incoming water gets colder. Figures are calculated from rated output (150,000 BTU × 0.8 UEF) and labeled as such — not bench-tested by us.
| Temperature rise | Typical scenario | Usable flow |
|---|---|---|
| 35 °F | Warm climate (75 °F in → 110 °F) — capped at max | 5.8 GPM |
| 45 °F | Mild climate (65 °F in → 110 °F) | 5.3 GPM |
| 60 °F | Cool climate (50 °F in → 110 °F) | 4 GPM |
| 70 °F | Cold climate (40 °F in → 110 °F) | 3.4 GPM |
Usable flow at a 110 °F target: BTU × UEF ÷ (ΔF × 500), capped at the 5.8 GPM maximum. We use the honest ~0.80 UEF, not the advertised ~97% thermal figure.
Pros
Cons
Buy it if…
- Mid-size homes wanting whole-house propane flow on a budget
- Tight installs — closets, laundry rooms, small utility spaces
- Cold-snap regions valuing built-in 41 °F freeze protection
- Buyers comfortable with a value brand's shorter track record
Skip it if…
- Buyers expecting condensing-level efficiency from the ~97% claim
- Anyone wanting a long, established heat-exchanger warranty
- Cold climates needing full 5.8 GPM in deep winter
Installation Requirements
Professional vs DIY
Propane and venting make professional installation the safe route for indoor use.
Gas and electrical work should be done by a licensed professional, and most installs require a permit and must meet local building codes — DIY work can void the manufacturer warranty. Always confirm the unit's own manual for exact clearances, venting, and sizing.
What owners report
Themes summarized from retailer customer feedback (4.6/5 Amazon customer rating, 14 ratings, as of 2026-09-06). These are owner opinions, not our own bench testing.
Early owners report near-instant hot water and enough flow for a mid-size home, at a price well below mainstream brands.
The small wall-mount cabinet is praised for fitting closets and laundry rooms where a tank wouldn't.
The high rating rests on only a handful of reviews — real long-term reliability is not yet well established for this SKU.
Coverage is a first-year free replacement rather than a long heat-exchanger term; keep documentation and register.
Gasland CE528LP FAQ
Is it really 96.9% efficient?+
That's the advertised combustion/thermal figure. The more meaningful Uniform Energy Factor for a non-condensing unit like this is around 0.80 — good for the price, but not the near-condensing efficiency the headline implies.
Is it condensing?+
No — it's non-condensing, so there's no condensate drain, but it needs proper venting and uses more gas per gallon than a true condensing unit.
How many fixtures can it run?+
Up to 5.8 GPM — roughly two bathrooms in warm/mild climates, dropping toward one to two in the cold.
What's the warranty?+
A first-year free replacement if it fails. That's shorter than the multi-year heat-exchanger warranties from mainstream brands, which is part of the budget trade-off.
What hot-water flow can the CE528LP deliver in winter?+
The 5.8 GPM rating is a warm-inlet figure. Estimated from its 150,000 BTU/h propane input at about 0.80 efficiency, realistic usable flow is roughly 5.3 GPM at a 45 °F rise but closer to 3.4 GPM at a 70 °F winter rise. That's still enough for two fixtures in mild climates or one strong shower in cold ones. Its freeze protection activates at 41 °F but needs power to work, so if you expect outages in freezing weather, drain the unit to protect the copper heat exchanger.
