Two gas tankless heaters close to it on our rating, each with a dated price.



That's the maximum flow the listing states, and headline flows are usually quoted at a mild temperature rise. A cold January asks for a 63 °F rise (42 °F in, 105 °F out), and at that rise every tankless gives less than its headline; the maker's chart says how much. Counting 2 GPM per shower, as our calculator does, that's a sink or one low-flow shower.
What it has going for it
Freeze protection. Stated in the listing. Useful in a garage, a crawl space or a cabin that sits empty in winter, as long as the unit keeps power.
Propane: that's what the listing names. A propane unit runs off a tank outside, so the tank size and the regulator are part of the plan.
Natural gas: it's a different set of gas jets and pressures. Only the maker's conversion kit, if there is one, and a licensed gas fitter can switch it; ask before you order.
The seller states, word for word, in the GASLAND BE158B Propane (1.58 GPM) listing:
The temperature rise is 109.4°F (43°C) at its highest point and 55.4°F (13°C) is at its lowest point of 1.58 GPM.
Runs on a standard 20 lb. liquid propane tank and is equipped with an electronic ignition powered by two D-cell batteries.
With CSA certification safe as per Canadian and US Standard.
That's the seller talking, not us. No listing tells you how it copes with 42 °F water at 6:45 in the morning.

What the GASLAND BE158B Propane (1.58 GPM) listing names:
Warranty & support: 1-year warranty, as stated in the listing · CSA, ETL or UL certification named in the listing.
That is the maker's promise, not ours. Keep the invoice, register the GASLAND BE158B Propane (1.58 GPM) if the maker asks, and read the install conditions: many tankless warranties need a licensed install and regular flushing.
The installation manual has the last word on venting, gas line and clearances; your installer reads it before you order.

At the price on Sep 30, 2026, each GPM of stated maximum flow works out at about $107.59 (price ÷ stated GPM, our arithmetic). That puts it around the middle of the 10 gas tankless heaters we have a price and a stated flow for.
The heater is often the smaller half of the bill: the venting, a gas line that may need upsizing and a licensed installer's day come on top.

Our take
We like the GASLAND BE158B Propane (1.58 GPM) for up to 1.58 GPM and built-in freeze protection. No buyer has reviewed it yet, so our 7.4/10 comes from the spec sheet alone. Where it falls short: no stated temperature hold, while most picks here claim ±1 °F. We'd pick it if you need one shower or one sink at a time, not the whole house; otherwise, put it next to the Rheem RTG 8.4 GPM Propane Outdoor first.
Old tank out, unit on the wall, vent through the wall or the roof. a licensed pro handles it, and often a permit.
Hot water arrives after the cold already in the pipes, then stays. It switches on at 0.58 GPM, so a trickle from a bathroom tap may not light it.
January water comes in colder, so the same unit gives fewer GPM. Stagger the showers if you sized it tight.
Flush the heat exchanger with a pump and a descaler (the service valves make it an hour's job), and clean the inlet filter. Our flushing and descaling guide has the checklist.
Before the GASLAND BE158B Propane (1.58 GPM) goes in your cart, check your winter flow: 1.58 GPM is a best case, so run your January numbers in our calculator first.
Count the fixtures that run together on a busy morning (our calculator uses 2 GPM a shower, 1.5 for the kitchen), then compare with the maker's chart. Our sizing guide shows how.
A licensed plumber or gas fitter confirms the vent route, the combustion air and a gas line that can deliver its full input. Get that quote before you order; our installation guide lists what they will ask.
1 years are stated. Read what it requires: a licensed install, the gas type and regular flushing are the usual conditions.
Hard water scales the heat exchanger. Service valves on the water lines turn the yearly flush into an hour with a bucket and a pump; our flushing and descaling guide shows the routine.

We rate it 7.4/10 (good). The rating comes from its documented listing alone, as no customer-review record is captured yet.
The listing states a maximum flow of 1.58 GPM. The headline flow is a mild-weather number: with cold winter water coming in, the same unit gives you less. Read the maker's flow chart at your winter rise, or let our flow-rate calculator do the sums.
Its listing states up to 1.58 GPM and freeze protection. These are the seller's figures, not our measurements: how steady the temperature is in your shower and how it copes with your winter water can't be read from a listing.
