Is it Time to Replace Your Hot Water System?

Hot water systems can be problematic. When they’re working, you would hardly every think about them. But as soon as they start playing up, it can be frustrating and very stressful.

Usually, all a hot water system needs is a service or repair to get it back into perfect working order. But eventually, there will come a time in every hot water system’s life when it needs to be replaced completely.

So how can you tell when a hot water system just needs to be fixed or that it’s reached the end of its working life?

The following signs all point to the fact that hot water system might be on its last legs. If you run through this list and check each of them as soon as you notice any issues with your hot water system, you’ll have a pretty good idea of whether it’s time to organise a repair, or start looking at replacement options.

If your hot water system is closer to 15-20 years old, and it has started playing up (making noises or tepid water), it’s almost certainly time to replace the unit.

If you’re in an older property, or you don’t have any information about when the hot water system was installed, it’s a good idea to get a professional plumber out to take a look and determine whether it can be repaired.

Is the water hot enough?

Before you rush out to replace the whole system, this problem can be often be caused by a faulty thermostat or a broken heating element. Sometimes, resetting the thermostat can improve the situation almost immediately. Replacing the thermostat might be the only work needed to restore full heating functionality.

This is something you can do this yourself, but make sure you get the correct type of valve with the correct pressure rating. If there is a leak evident, it may need replacement. It’s always best to call an expert it to check it for you.
