1.5 Gallon Aquarium Heater Options for Nano Tanks
As an Amazon Associate we earn from qualifying purchases.
Finding a 1.5 gallon aquarium heater is harder than it sounds, because the product data we have for this keyword holds no stand-alone heater at all. What it does hold is six nano setups, five of them 1.5 gallon kits and one a 2.5 gallon kit, plus two clip-on lights. Only one of the six, the Oltraman kit, lists a heater among its parts. This guide goes through what each listing actually includes, so you can see which tanks arrive without a heater and what to look for when you add one.
Quick answer
- Only the Oltraman 2.5 gallon kit lists a heater in its contents. The listing does not give the heater’s wattage or temperature range.
- The five 1.5 gallon kits (Craftsboys, iPriro, Wagrvuy, Dimind and ERAARK) list a filter or pump and a light, and none lists a heater.
- The two clip-on lights in the data (Pawfly and Novique) are lights, not heaters, and are left out of the picks below.
- For a heater that fits a 1 to 5 gallon tank, see our separate heater guides linked at the end.
What a 1.5 gallon setup has to solve
A 1.5 gallon tank holds very little water, which has two consequences for heating. There is little room inside for equipment, and the temperature moves quickly when the room changes. That is why a heater for this size has to be small and why the kit design matters: a tank with a hang-on-back filter keeps the inside clear, while a tank with a submersible pump and sponge puts more hardware inside the water.
The listings here do not give a recommended temperature for any fish, and we do not offer one. Ask a vet or an experienced fish store for the temperature range that suits the species you keep. What the listings do allow us to do is compare size, material, what is in the box and what is not, which is the information you need to plan a heater purchase.

The kits, one by one
Oltraman 2.5 Gallon Betta Fish Tank Kit (the only one that lists a heater)
This is the one listing that names a heater. The seller describes a complete starter kit with an LED light, rock, heater, filter, pump, net, thermometer sticker, water changer and gravel cleaner. The tank is 2.5 gallons, not 1.5, and the footprint is 12.3 by 10.2 by 7.1 inches, so it is wider and lower than the glass cubes. The listing also describes a self-cleaning system in which plants grow alongside the fish, a waterfall feature, three LED lighting options and artificial plants. The pack shows an air pump, filter, light, plant and rock as the components and a one-year manufacturer warranty. The weight is 3.55 kg. The target species list is long and includes betta, guppies, angelfish and shrimp, which is the seller’s wording and not a care recommendation. The listing gives no wattage for its heater, so if you need to know whether it suits your room, ask the seller. If you have space for 2.5 gallons and want the heater included, this is the match.
iPriro 1.5 Gallon Glass Betta Starter Kit
The iPriro kit is a square glass tank about 6.3 inches on each side and 8.67 inches tall, with 4 mm glass, a black back panel and a black EVA base cushion. The listing gives details for the hang-on-back filter: 2.5 watts, 250 liters per hour, with adjustable flow, and a reminder to fill the filter with water before every start-up. The clip-on light is listed at 8 watts and 450 lumens, full spectrum, and the kit includes a lid. The seller names betta, guppy and angelfish as suitable fish, which we treat as the seller’s description. The pack shows a one-year warranty and a weight of 2.49 kg. There is no heater in the contents. Because the filter hangs on the back, the inside of the tank is empty, which leaves the most room for a small heater of your own choosing. The lid is also worth noting, since the seller says it is custom made.
Craftsboys 1.5 Gallon Nano Glass Starter Kit
The Craftsboys tank is the other glass cube, with a footprint of 6.29 by 6.29 by 8.66 inches and glass 4.2 mm thick. The listing describes a 3 watt hang-on-back filter with adjustable flow and a 3 watt COB LED light. The seller recommends it for aquascape beginners and says it is also a good tank for small fish. Contents include the filter, light, decorations and a fish care guide. The weight is 2.17 kg and the warranty reads one month, the shortest in this group. There is no heater in the contents. This listing is a fit for someone who wants a tank to plant and decorate first, with equipment added afterwards.
Wagrvuy 1.5 Gallon Plastic Tank Kit
This tank measures 8.7 by 6 by 10 inches and is made of PET plastic, according to the listing, which also gives the spec material as polycarbonate. The seller says the plastic avoids the weight and fragility of glass and weighs 1.07 kg, the lightest in the group. The kit includes a silent pump, a tricolor LED light powered by USB (adapter not included) and plastic plants. The listing says the tank is designed for cold-water species such as betta, goldfish and shrimp. That statement is worth reading closely: it describes the tank as made for cold-water species, and the contents list no heater. If you want to keep a fish that needs warmer water, check the care needs with a vet or fish store first. The listing also advises washing all components with clean water and air-drying them before use.
Dimind 1.5 Gallon Floating Acrylic Tank
The Dimind tank is oval, made of clear acrylic, and sits on a floating base. The listing describes a 360 degree view, 7-color LED lighting, a submersible pump and filter sponge running under 30 dB, and a bottom drain system for removing waste. Contents are the tank, pump, filter sponge and light; decorations shown in the photos are not included. The listing names betta, guppies, shrimp and small aquatic pets. Package dimensions are given as 11.6 by 10 by 6.1 inches and 2.1 pounds. Since the pump and sponge sit inside the water, the free space for a heater is smaller than in the cubes with hang-on filters. The listing does not state its inside dimensions, so measure before adding equipment.
ERAARK 1.5 Gallon Betta Tank Kit
The ERAARK listing gives a size of 6.4 by 6.4 by 8.3 inches and a 1.5 gallon capacity. It is made of ABS, with a light whose color the seller says you can change among red, orange, yellow, green, blue and purple, and a filter that uses multiple pieces of filter cotton for physical filtration. The kit holds the aquarium, LED light, filter and water pump; fish and sand are not included. The warranty is listed as none. Without a stated heater, it is the same story as the others: add your own. Its weight is 1.25 kg and the package is 9.72 by 7.95 by 7.83 inches.
Why the two lights are not in the picks
The data for this keyword also lists the Pawfly 6W LED clip-on light for 1 to 5 gallon tanks and the Novique 8W clip-on light. Both are lights. The Pawfly listing describes full-spectrum light, six intensity levels and a timer, and the Novique listing describes a rotating gooseneck. Neither listing mentions heating, so they do not answer a heater question and we have not linked them here. They might suit one of the kits above if its own light is not what you want, and our light guides cover that.
Filters and lights side by side
Because a heater shares the tank with the rest of the kit, it helps to see what else will be running. The iPriro lists a 2.5 watt filter at 250 liters per hour with adjustable flow and an 8 watt light rated at 450 lumens. The Craftsboys lists a 3 watt filter with adjustable flow and a 3 watt COB light. The Wagrvuy lists a silent pump and a USB light with three color modes, and notes that the USB adapter is not included, so you will need to supply one. The Dimind lists a submersible pump with a sponge and says it runs below 30 dB, with a seven-color light. The ERAARK lists a filter with several pieces of filter cotton and a light with changeable colors. The Oltraman lists an air pump, filter and light in the contents.
Two practical notes follow from this. First, every one of these kits needs a mains socket or a USB adapter for each powered part, so count the plugs on your desk before you add a heater. Second, adjustable flow, which the iPriro and Craftsboys listings both mention, is a useful feature in a tank this small, because a heater sitting close to a strong outlet can end up in the current. The listings do not give placement advice, so follow the instructions that come with the heater you choose.
The size of the tank also affects what you can hide. The glass cubes are about 6.3 inches square, so a heater that is a few inches long will stand upright in a corner, while the wider Wagrvuy at 8.7 by 6 inches and the Oltraman at 12.3 by 10.2 inches give more room to lay equipment out flat. The listings for the Dimind and the ERAARK do not state the inside dimensions, so measure the interior yourself if you have a particular heater in mind.
What to check before you add a heater to a 1.5 gallon tank
- Inside space. A cube with a hang-on-back filter leaves the inside empty. The Craftsboys and iPriro kits use this layout. The Dimind and ERAARK kits use an internal pump, which takes up space.
- Heater size. Use a heater whose own listing states a tank range that includes 1.5 gallons. Do not choose by the keyword alone, because many “small” heaters start at 2 gallons.
- Material. The kits here are glass, polycarbonate, acrylic and ABS. A heater listing should say it suits the tank material; some listings name glass or acrylic tanks specifically.
- Warranty. Warranties range from none (ERAARK) to one year (iPriro, Oltraman), and the heater will have its own.
- Safety. Look for listing text on overheating and out-of-water protection, and follow the directions for submerging before plugging in.
FAQ
Does any 1.5 gallon kit here include a heater?
No. The five 1.5 gallon listings contain a filter or pump and a light, and none lists a heater. The only kit with a heater is the 2.5 gallon Oltraman.
Is the Oltraman kit the same as a 1.5 gallon heater?
No. It is a 2.5 gallon tank and the listing does not state the heater’s wattage, so we cannot say how it would suit a smaller tank.
Which 1.5 gallon tank has the most room for a heater?
The two glass cubes, iPriro and Craftsboys, both use a hang-on-back filter, which keeps the water space clear. That is a layout observation drawn from the listings, not a measured clearance.
Which kit is lightest?
The Wagrvuy plastic tank is listed at 1.07 kg, the lowest weight among the kits.
Can I use the lights above to warm the tank?
The listings describe them only as lights and say nothing about heating the water. Use a heater made for the job.
What temperature should I set?
The listings do not give a temperature for the fish. Ask a vet or a fish store for the range your species needs.
Bottom line
If you want a heater included, the Oltraman is the only listing that names one, at 2.5 gallons. If you want a true 1.5 gallon tank, plan to buy the heater separately and pick a kit by layout: a hang-on-back filter for the most free space, an internal pump if you value a floating or acrylic look. Check that any heater you buy states a tank range that includes 1.5 gallons.
