Best for Hobbyists – Wilesco D18 Steam Engine with Generator
If you’re already a model steam engine geek, this is definitely the one for you. The Wilesco D18 Steam Engine with Generator is one of the pricier products on the market, but it’s very well made. The craftsmanship is beautiful and it feels very solid – it oozes class and quality. It’s versatile too because you can connect other accessories with the flywheel. The little street light is a nice touch as well! Overall, this model is just very well done in all areas.
Along with the quality of the product, my favorite thing about this model is the sounds it makes. If you’re a steam engine nut, you’ll appreciate the noises it generates – it just sounds like a real steam engine would sound! It’s hard to get the steam whistle to sound right in model products, but this one is almost spot on. Given the hefty price tag for this model, it’s probably better suited to adult enthusiasts rather than children learning about STEM, but either way, it will definitely impress its users.
Best Budget Option – DjuiinoStar Mini Hot Air Stirling Engine
DjuiinoStar Mini Hot Air Stirling Engine
A pocket-sized model that packs a punch and holds its own for quality and performance.
This model engine is not only small in price – it’s also small in size! The DjuiinoStar Mini Hot Air Stirling Engine is slightly smaller than a soda can but does everything the larger models can do. Despite its less expensive price tag, it’s made from quality materials such as the mirrored stainless steel base. It not only feels solid, but it also looks good.
If you’re after a desktop toy, the compact design means it won’t take up much room on your workspace. It’s also a great option for teachers because it’s small in size and lightweight, which means it’s easy to move between classrooms.
The mini design is a full working model. There’s no assembly required though, so if you prefer to construct your model you’d be disappointed. Otherwise, you can start converting energy straight away! The Stirling engine might be small in stature, but there’s no lack of attention to detail. For example, the glass jar has a magnet under it to hold it in place. I also appreciated the instructions – clear and concise without unnecessary details.
Best for Younger Kids – Playz Model Steam Engine Kit
If you have a younger child that can’t get enough trains in their life, this is the product for them. The Playz Model Steam Engine Kit is a great buy for a younger audience. The locomotive design means it’s a bit more child-friendly than the other models and they will love seeing the steam come out of the train’s chimney. They can also get the lights to flash and the whistle to blow. It’s every train-lovers dream!
This kit is full of good quality pieces that fit together nicely and it feels like a nice, solid product once it’s all assembled. The instructions are really worth a mention too. They’re perfect for children: clear and easy to understand with plenty of colorful diagrams, rather than a lot of text. This is helpful for younger minds and means they won’t need a lot of adult help putting it together. This steam engine kit is marketed at children aged 10 and up though, so younger children may still need a bit of adult assistance.
If you’re buying your model steam engine kit with kids in mind, this one is the ideal choice.
Best for Educators – Sunnytech Mini Hot Live Steam Engine Kit
This steam engine kit is simple, but it works well and it’s one of the best at showing exactly how steam engines work. The Sunnytech Mini Hot Live Steam Engine Kit uses a V-twin cylinder/piston set up and this makes it very easy to see the energy transfer process in action. This would be the perfect model for teachers or anyone who wants to explain the process to others (or learn it for themselves!). Keeping it simple is often the best way to see the process clearly, and that’s what this model does well.
Assembly is required for this steam engine kit, but it’s not complicated. The manual is easy to follow and all the pieces go together well. Once assembled, the model feels quite solid and it’s really simple to get things moving. It ran a little rough, to begin with, but started running smoothly after a few goes. It’s an impressive option for educators or anyone who wants to take a closer look at the energy transfer process.
What to Consider when Buying a Model Steam Engine Kit
Safety should be your number one consideration, especially if you’re buying a kit to use with children. Model steam engine kits can get very hot and usually remain hot for a while after use. Many of them use breakable materials like glass and they often flick or spray hot liquid about. Of course, adult supervision should always be used but even so, make sure you consider whether the kit you’re buying is safe and suitable for the intended age range. There are plenty of safe, child-friendly models on the market so make these your number one picks.
When you’re looking at model steam engine kits, you’ll notice the quality of construction varies greatly. You get what you pay for but whichever kit you choose, make sure it’s made of solid materials that are appropriate to the task at hand. There’s nothing more disappointing than getting your kit home to find a switch is broken. Or you’ve spent a long time assembling the product only to find the pieces don’t fit together well. It might be worth spending a little bit extra to make sure you get a kit that won’t let you down or present a safety hazard.
It’s easy to get carried away when you’re shopping for a model steam engine kit. They’re all so cool that you could easily blow your budget if you’ll go with the top of the range model. But think about what you need the kit for. Do you want to use it frequently or will it be something you only use a few times to show someone how the steam engine process works? Do you want a model you can display on your desk or on a shelf, or are you happy to put it back in the cupboard after use? There’s no point in spending a lot of money unless you want this to be a real investment. The less expensive models are usually still of good quality and will do exactly what you need them to do.
