Gas Carpet Cleaning:

In 1927, W. E. McCorquodale invented and was granted a patent on the first thermostatically-controlled instantaneous gas water heater. He called the device the “Hotomatic.”

Today, Little Giant has taken his original ideas and improved on the design to offer a dependable, reliable, and long lasting water heater for the carpet cleaning industry.

Using today’s technology and the original ideas of Mr. McCorquodale, we manufacture a heater that rivals any exhaust heat exchanger on the market, at half the cost.

We offer btu ratings from 65,000 to 180,000 for even the largest systems. We also offer pressure ranges from 600psi to 2200psi for tile and grout cleaning. Our three models, the #2HT, #3HT, and #4HT are designed to cover all areas of carpet cleaning and tile & grout cleaning. 

We now are offering extreme high pressure models in the #3HTXP and #4HTXP to cover everything else.

Portable Carpet Cleaning:

We are proud to offer the #2 and #3 Little Giant Hotomatic heaters in a small compact cart system to reach those inaccessible and hard to reach carpets.

These systems are full turn key systems that include a dolley cart, the #2 or #3 heater, gas regulator, pressure relief valve, LP hose, and 20# LP tank.

The system also comes with the tank foot and fasteners to attach everything securely to the cart. Everything you need to take your hot water with you. 

Not to be used indoors without proper ventilation due to the risk of carbon monoxide poisoning. 

Electric portable heaters

An electric portable baptistry heater is the most popular choice because it can be used for baptistries such as portable baptistry, single-entry baptistry, or double-entry baptistry, as they’re relatively economical and easy to install. However, they can have less heater efficiency than other types of heaters, and they may not be able to warm the water as quickly as some people prefer.

Electric Circulation heaters

Electric circulation heaters are more expensive than an electric immersion heater, but they’re much more energy efficient. They also tend to warm water more quickly, making them a good choice for people who want to be able to take a quick dip in their baptistry.

Gas Heaters

Gas-fired heating systems are the most expensive option, but they’re also the most energy efficient. They’re also very fast, so they’re ideal for people who want to be able to get in and out of the water quickly.

How to pick the right baptistry heater for you

When choosing a heater, the first thing you need to consider is the size of your baptistry. Baptismal heaters are available in a range of sizes, so it’s important to pick one that will be able to warm the entire pool. You also need to consider the location of your baptistry. If it’s located outdoors, you’ll need to make sure that the heater you choose is weather-resistant.

Finally, you need to consider the power source. Baptismal heaters can be powered by electricity, propane, or natural gas. Choose the power source that is most convenient for you and that you have easy access to. With these factors in mind, you should have no trouble picking the right baptistry heater for you.

How a portable baptistry heater operates

When you turn on an electric immersion heater, an element begins to warm up. This element is submerged in the water, which causes the water to warm up as well. The element will continue to warm up until it reaches its thermostat settings, at which point the thermostat cuts the heater off. 

Gas-powered baptistry heating process:

When you turn on a gas baptistry heater, a pilot light will ignite the propane or natural gas that is flowing into the heater. The warmth from the pilot light will then cause the propane or natural gas to explode, which creates heat that is used to warm up the water. The heated water rises through the pipes and into the baptistry.

FAQs about baptistry heaters

How long does it take the average heater to heat up? This can vary depending on the model and size of the heater, but most of our heaters will bring the water temperature up to between 90 and 95 degrees Fahrenheit in around an hour.
