If you have recently moved into a new property, particularly one that may be older and need a little bit of modernising, you may find that it still uses an old water tank system for hot water. Even some relatively newer properties still operate water tanks, particularly where there is no gas supply and only an electric one. This month we look at the options available to you to replace that old water tank with a newer, more efficient hot water system.
Hot water-only systems
If you are on a separate heating system or only have electricity without a gas supply to your home, a hot water-only system may be the best option for you. There are two options to choose from:
- Instant systems. These will heat water on demand and are also known as continuous flow systems. Cheaper than storage systems as they only heat the amount of water you need they are also good options if you have space restrictions. They will work best with high flow rates so if your water pressure is low you may need a back-up pump. For homes with numerous water outlets your flow rate should be high.
- Storage tank systems. These are a great option if you are on an off-peak energy tariff and have enough space for a tank. They work by heating water during off-peak times and storing it for the day. The downside? Once the hot water is used up there is no more left unless you heat it up again. If this is likely to happen during peak electricity times it could end up being an expensive option.
The benefits of electric water systems are realised if you do have access to off-peak energy tariffs, and they are available in a wide range of sizes which could suit any home and family size.
Gas hot water systems
If you have a gas supply and are also considering combining hot water with central heating then a gas combi boiler is probably your best option.
Although they are more expensive to install than electric hot water systems, they are cheaper to run as gas is less expensive than electricity. They operate on either natural gas or LPG (liquid petroleum gas) and will need to be vented. This means that they will either need to be installed outside the home or have a flue for indoor installations.
Hot water heat pumps
A relatively new option on the market, hot water heat pumps work by harnessing heat as it moves from one place to the other rather than generate it. They are increasing in popularity as they are more energy efficient than conventional electric hot water heaters and come in a range of sizes to suit your household needs.
