How to be more efficient with your hot water

For most people, central heating and hot water make up the largest part of their energy bills, especially over the winter months. If you are on an economy drive, it makes sense to look at these areas and see if there is potential to make savings.

Types of systems

First, you need to understand what type of heating system you have. Smaller properties these days often have a combi boiler. These types of boilers will heat water on demand, so when you turn on the hot tap, the boiler fires up and there may be a short delay in the water that comes through the tap getting warm.

Larger properties or those that have more than one bathroom are more likely to have a conventional or system boiler that heats water and stores it in an insulated cylinder.

What are the pros and cons of these technologies? With a combi system, you will always have hot water whenever you want it with no effort. With a storage cylinder, it is possible to use up all of the water and have to run the boiler again to heat up some more; this is always more efficient than using an immersion heater. The best type for you really depends on the size of your family and how you use water throughout the day. If you are likely to need hot water in more than one location at once, a combi is probably not the best option.


To save money on your water heating, you need to make sure your boiler is running efficiently. Companies offering boiler repair Gloucester, such as http://www.hprservicesltd.com/gloucester-boilers/boiler-repair-gloucester/, will be able to service your boiler and make sure it’s running at its best.

If you have a hot water cylinder, make sure the cylinder and the pipes surrounding it are properly insulated. A good modern cylinder should be able to keep water at an acceptable temperature for several hours.

Bear in mind that appliances like washing machines and dishwashers these days are fed with cold water only and do their own heating as part of the process, so they won’t be using hot water from your boiler.
