Best Portable Water Heater – Buying Guide & Reviews


Many people are reluctant campers. They love the outdoors, but they prefer the luxury of home conveniences. However, there is a product that has changed the minds of many reluctant campers — the portable water heater.

A portable water heater not only provides campers with warm showers and hot water for dishwashing and hand washing, but it is very useful in the home as well. It can be used for washing your dog, washing your car or patio furniture. You can even use it for thawing frozen water lines, for shampooing rugs, or for giving your horse a delightful treat on a cold winter’s morning.

There are both tank-type and portable tankless water heater models. Some of them are free-standing, others are table-top units, or units that need to be hung from a nail or the branch of a tree.
