The Best Bivvy Heaters

2021 Review by Jason Sawyer

The best bivvy heaters are the ones that are SAFE and can provide you with the right amount of warmth without burning a hole in your pocket.

When fishing in the cold I always recommend taking thermal fishing clothing and a sleeping bag to keep warm, which is far safer than accidentally leaving a gas heater switched on inside your fishing tent. It’s just not worth the risk! If you have to use a heater inside your bivvy when you sleep then opt for a decent candle lantern instead.

In this article, I’ll guide you through the best bivvy heaters available. I’ll cover important things to look at when selecting a bivvy heater, and I’ll also review five of my favourite heaters for bivvy use. Let’s crack on:

My Top 3 Bivvy Heaters

Here are my 3 best bivvy heaters for chasing that chill out your fishing bivvy while you sleep:

Best Overall: UCO 3 Candle Lantern

3 Candle Lanterns from UCO are a safe and reliable heat source for your next fishing trip. The lanterns have three built-in candles that provide a warm ambient glow and reduce condensation, helping to keep the inside of your tent dry and clear of flying insects. The windproof glass chimney helps contain the flames in strong winds so you can enjoy their warm glow at night.

My Top 5 Portable Gas Camping Heaters

You can use these portable gas heaters outside your bivvy or temporarily inside your bivvy (providing there is adequate ventilation) to warm it up before you go to sleep, but never fall asleep or lie down next to a gas heater inside your bivvy or you’re at serious risk of gas poisoning, lack of CO2 and death. Just use a bit of common sense and you can still use a gas heater to stay warm.

Frequently Asked Questions

Here are some common questions I get asked about bivvy heaters:

Are bivvy heaters safe?

Unless you have a proper ventilation system portable gas heaters should never be used inside as bivvy heaters. Carbon monoxide gas poisoning kills anglers every year. This UCO 3 Candle Lantern positioned on your table or hung on a bivvy hook is much safer and more economical.

If you want to really keep toasty inside your bivvy then instead of using a bivvy heater try the NGT 5 Seasons Sleeping Bag or these fishing fleeces which I take with me during winter seasons.
