How to Boost Your Water Heater Performance

If you’re finding it takes longer to wait for hot water, this could be a sign your water heater isn’t working as well as it could. The Water Heater Company can help you boost your water heater performance. Alternatively, there are many ways of helping your water heater at home, depending on the season. 

The preparation you use depends on the water heater to improve its performance or you can look for the cause of the problem such as sediment build-up. Here are a few ways you can improve the performance of your water heater.

Keep your pipes insulated

During the winter, your pipes are more likely to cool down due to heat loss if they’re not properly insulated. If part of your pipework is exposed, consider covering it in foam insulation. This will reduce their chances of freezing, and either reducing their level of performance, or at least keep them from bursting.

Insulate the tank itself

If you have a tank water heater you can use an insulating blanket or jacket specifically designed for water heaters. This will help it retain the heat. You may need professional help with this especially if you have a gas water heater with vents and pipes that need to be exposed. A water heater company can also insulate the tank for you.

Check for leaks

Often reduced water temperature is caused by a leaky dip tube. The dip tube normally runs cold water through the tank without cooling down the hot water, but if it’s leaking this could affect the temperature of the water. 

Inspect the dip tube for cracks or corrosion as these could cause a leak and mean it needs replacing. If you’re concerned your water heater or any parts need repair or replacing, contact a water heater company.

Remove excess sediment

One of the reasons your water heater might not be performing as it should, could be a build-up of sediment such as limescale. This can clog the valves and reduce water flow. A telltale sign you have a sediment build-up is strange noises coming from the water heater. 

You can dissolve this sediment using phosphoric acid or vinegar, but it’s best to seek advice from a water heater company first. They will be able to flush your water heater of any excess sediment for you.


Take preventative measures such as sealing off any drafts in doors and windows around the water heater, particularly if it’s situated in a cold environment. You can also carry out regular maintenance on your water heater, for example draining and flushing. 

This is the process of removing loose sediments before they create a problem. This can be done by attaching a garden hose to the drain valve, while the water heater is switched off. A professional water heater company can help you with this. 

If you’re concerned your water heater isn’t performing as well as before, or that it might need repair or replacement, contact The Water Heater Company for professional advice.
