While some people change to a new type of hot water system when their old one needs replacing, you can simply go for a like-for-like replacement. Here, you stick with the same type of energy supply and even the same manufacturer.

A like-for-like replacement has its benefits. For example, you're likely to see reduced installation costs. How will you save money?

1. Stick With Your Current Placement

While the parts of your hot water system are in specific places now, you might need a different configuration if you install a different type of system. If your new system is bigger than your current one or needs a different venting placement, then you might need to move it somewhere else. You might have to run extra pipes and connections to make the system work in its new position.

The more work you have to do to move a system, the higher your installation costs will be. You'll pay for extra parts, and your labour costs will be higher because the job will take longer. If you stick with a similar system to the one you already have, then you can simply slot each part in the same place.

2. Use Existing Connections

A new type of hot water system might not match your current pipes and connections. You might need to install different types of pipes and valves or put new ones in different places. These parts, and the work it takes to set them up, add to your installation costs.

If your current hot water system isn't too old, then its pipes and connections might still be in good shape. If you're lucky, you can attach a new like-for-like system without installing new pipes and connections. Even if you do need to replace some parts, they'll go in the same places. So they're easier and quicker to install.

3. Avoid Power Switching Costs

If you install a hot water system that uses a different kind of energy than your existing one, then you have to pay extra costs. You have to set up your new power source and, sometimes, disconnect the old one.

For example, if you install a new gas hot water system, then you might have to pay for a gas connection and pipe installation. Or if you switch from gas to electricity, then you'll pay to have your gas supply to your hot water capped and disconnected. You might need to upgrade your electrics to cope with the new system.

If you stick with the same hot water system, then all your connections are in place. You won't have these extra costs.
