Installing an Instant Water Heater Installing an Instant Water Heater

What You'll Need
Drill with masonry bit
Spirit level
Wrench and socket set
Electric cabling (for an electrical installation)
Iron piping (for a gas installation)
Soldering iron and solder

Providing hot water on demand, an instant hot water heater can be an extremely useful thing to have in any home. Instant hot water heaters are different from the traditional tank water heaters. The traditional heaters heat up water slowly and then store it for later usage. An instant hot water heater can save money since there are no tanks involved and electricity consumption is considerably lower. Less water needs to be heated and there is no wastage since hot water is provided on demand.

Step 1 - Make the Preparations

Determine the best place for installing the new water heater. The location may be subject to certain local planning permission rules and regulations. It will also need to be a certain distance away from utilities and from various structural components. Refer to your local planning permission regulations for more information.

When you have determined the location of the hot water heater, mark its position on the outside of the wall for the vent. Also, you should mark the location of the heater unit. This will serve as a template for mounting it.

Electrical cabling or iron piping (depending on whether the heater is gas or electrically powered) will need to be installed to reach the location of the heater. A licensed tradesman should do this.

Step 2 - Making the Vent Hole

Drill a pilot hole through the mark that you specified for the vent hole. When you have drilled the pilot hole, drill out the hole to the width recommended by the manufacturer of the water heater.

Step 3 - Place the Heater on the Wall

Using the template guidelines that you drew earlier on the wall, attach the heater to the wall. Use the brackets and bolts provided with the kit to mount it on the wall securely. You should also make sure that it is completely level before attaching it permanently. To do this, use the spirit level.

Step 4 - Assemble the Vent Pipe

You will then need to construct the vent pipe. The elbow of the vent pipe should be located on the top of the heater and you will need to have somebody helping you on the exterior side to attach the exterior part of the vent. The exterior part of the pipe needs to be slid into the vent hole and attached to the elbow of the pipe.

Step 5 - Connecting the Water Heater to the Gas or Electricity Supply

While the process of mounting the heater and constructing the vent is not a particularly challenging one, it is strongly advisable that a licensed professional attach the gas or electricity to power the heater. When everything has been assembled, the installation will need to be thoroughly tested before usage. Buckets should be placed under the valves of the water heater unit and valves should also be opened to remove any air from the pipes.
