Portable Water Heaters

At National Heater Shops, our selection of portable water heaters and hot water pumps help to supply fast, safe warm water.

Temporary Heating Solutions

Our portable water boilers are ideal for temporary solutions for use on construction sites, temporary builds, during events, or for use in emergencies. A portable electric heater can be used safely on sites with no gas or oil supply, meaning they are reliable and can be used anywhere there is a suitable power supply or generator available.

Easy Installation

Our portable water heaters are easily installed and relocated. They come mounted on a trolley frame, so they are easily transported around an area wherever warm water is needed. Their tough, industrial design allows them to be used across a multitude of industries safely and without risk.

Electric Under Sink Heaters

Our selection of portable water heaters also include electric under sink heaters. These heaters are designed to be installed under a sink to provide warm water without the use of a gas or oil supply.
