Have Questions About Chillers?

We have answers. Get quick help for common questions.

What size aquarium chiller do I need?
The size of your chiller depends on your aquarium’s total water volume, heat sources, and the temperature difference needed. Generally, the larger your tank or the warmer your ambient room, the higher the BTU/hr or cooling power required. Product listings on Charterhouse Aquatics specify suitable tank sizes for each model.
Can I use a chiller with a reef tank?
Absolutely. In fact, chillers are often essential in reef systems where temperature stability is critical for coral health. Many reef aquarists rely on chillers to offset heat from strong lighting or enclosed cabinetry.
Do I need a controller or thermostat?
Most aquarium chillers include built-in digital thermostats, but for fans or non-integrated setups, a dedicated aquarium temperature controller can help automate and safeguard your tank’s climate.
Are fans or chillers better for cooling an aquarium?
Fans are great for small to medium tanks with slight overheating issues and are more energy-efficient. Chillers, on the other hand, are ideal for larger systems, reef tanks, and cases where consistent temperature control is essential. In extreme cases, a fan alone may not be sufficient.
How do aquarium fans cool the water?
Aquarium fans promote evaporation at the water surface, which naturally lowers the temperature. While not as powerful as chillers, fans are easy to install, energy-saving, and effective in moderately warm conditions.

Stay Cool, Keep Your Tank Stable

Temperature fluctuations can cause stress, illness, and even death in sensitive aquatic species. That’s why choosing the right cooling solution—whether a compact aquarium fan or a full-performance chiller—is one of the smartest investments you can make for your tank’s long-term health.

Good to know

Why are some points pending?

Purchase points have an approval period before they become available. Your balance shows available points separately from pending points.

How long do my points last?

When points expiry applies, your balance stays valid for 365 days from qualifying rewards activity. Earning eligible rewards, redeeming points or a balance adjustment renews that window. Simply visiting the shop does not renew it.

Can I use points with my stamp reward?

Yes. Add your 10% stamp reward code at checkout and switch on your points. Your final saving depends on the eligible product total and any other discount restrictions.

What happens if I return something?

Earned points are adjusted for returns. Points used on refunded products are restored proportionally. If a refund takes a qualifying order below £250, its stamp is removed.
