If you are planning on having a new hot water system installed in your home, there are a few things you should check and do which will help to keep things running smoothly. Follow the tips below to ensure that your new hot water system has a long and efficient life.

Check the insulation

Insulation is a key part of your hot water system. A properly insulated water heater will not lose heat energy, ensuring that your water is heated in an efficient and environmentally friendly way. To check that your heater has adequate insulation, you should place the palm of your hand on the side of the tank when it is in use. If you can feel any heat, it is likely that the tank requires better insulation. Your plumber should be able to recommend a suitable insulation blanket which can be wrapped around the water heater.

Check the ventilation

If your water heater has been installed in an enclosed space, it is extremely important that you ensure that the area has enough ventilation. If the area does not have adequate venation, condensation may begin to form on the outside of the tank as it begins to 'sweat'. If it is left to gather, this moisture can cause water damage and mould growth in other areas of your property. To ventilate the space around the water heater, you should install a wall vent placed relatively high up, to allow any hot air which gathers there to dissipate. 

Check the sacrificial anode

Your water heater contains a rod of magnesium or zinc, called a sacrificial anode, which is designed to prevent corrosion inside the unit. You should ask the plumber installing your unit to check that the sacrificial anode is present and correct before they install the unit. This will help to ensure that your tank will be protected against corrosion for years to come.

Make sure the tempering valve and thermostat are configured

The final thing you need to check is that the tempering valve, which will prevent water in the heater from exceeding a certain temperature, and the thermostat are correctly set. The instruction manual supplied with your hot water heater should detail exactly how to do this, but if you are in any doubt, you can also ask your plumber to explain.

After installation, if you have any questions or concerns about your water heater you should contact a hot water service professional.
